ForewordThe Department of Water (Department) has prepared this Drinking Water Source Protection Plan (DWSPP) to report on the activities and risks to water quality within the Victoria Reservoir Catchment Area and to recommend management strategies to minimise the identified risks.

A safe drinking water supply is critical to the wellbeing of a community and catchment protection is necessary to help avoid, minimise or manage risks to water quality in Public Drinking Water Source Areas (PDWSA). The Department is committed to protecting these areas to ensure the continued supply of ‘safe, good quality drinking water’ to consumers to protect public health now and in the future.

The Australian Drinking Water Guidelines recommend a multiple barrier ‘catchment to consumer’ approach to protect public drinking water. The protection and management of a PDWSA is the ‘first barrier’, with subsequent barriers implemented at the water storage, treatment and distribution stages of a water supply system. Catchment protection includes:

• understanding the catchment, the hazards and hazardous events that can compromise drinking water quality; and

• developing and implementing preventive strategies and operational controls necessary to ensure the safest possible raw water supply (i.e. before treatment).

This Plan details the location and boundary of the drinking water catchment that provides potable water to the Integrated Water Supply System. It discusses existing use of the water source, describes the water supply system, identifies risks and recommends management approaches to maximise protection of the catchment.

The Plan should be used to guide State and local government land use planning decisions in Western Australia. This DWSPP should be recognised in the Shire of Kalamunda, City of Gosnells and City of Armadale Town Planning Schemes and other local planning strategies and plans, consistent with the Western Australian Planning Commission’s Statement of Planning Policy No. 2.7 Public Drinking Water Source Policy. Other stakeholders should use this document as a guide for protecting the quality of water in the PDWSA.

Department of Water 1


SummaryThe Victoria Reservoir and its catchment are located in the Darling Range approximately 25 km east of Perth. The reservoir was constructed in 1891 on the Munday Brook, a tributary of the Canning River, and was the first permanent source of drinking water for the Perth metropolitan area. Victoria Reservoir is now an important source of public drinking water for the Integrated Water Supply System which provides scheme water to Perth, Mandurah, Pinjarra, Harvey and the Goldfields agricultural regions.

The Victoria Reservoir Catchment Area was proclaimed in 1923 under the Metropolitan Water Supply, Sewerage and Drainage Act 1909 to ensure protection of the water source from potential contamination. An amendment to the original boundary has been agreed on to ensure it more accurately represents the physical catchment boundary.

The objective of this Drinking Water Source Protection Plan is to protect the quality of drinking water in the Victoria Reservoir Catchment Area for public supply. In part, this can be achieved through the decision making and management processes that are used to approve land use practices and activities in the catchment. The following Plan:

• identifies potential drinking water quality contamination risks from land use activities within the catchment; and

• recommends strategies to manage these potential risks whilst recognising current land use rights.

Much of the Victoria catchment is under Crown ownership with an extensive area being State forest. A Special Lease (granted under the State Agreement Act) covers part of the Crown land in the catchment and enables bauxite extraction by Alcoa of Australia. To date, no mining activity has occurred in the catchment and there are currently no plans to mine this area.

State forest is managed for the purposes defined in the Forest Management Plan 2004-2013 as conservation, recreation, timber production on a sustainable yield basis, water catchment protection and other purposes prescribed by the regulations. The Forest Management Plan is a statutory plan for State forest and recognises water catchment protection as a statutory purpose of State forest.

The Kattamorda Heritage Trail and the Munda Biddi cycle track pass through the catchment, and a golf course and shooting range are also located in the reservoir’s catchment. Unauthorised recreational activities within the catchment include fishing and marroning, camping and off-road vehicle use. Rubbish and vehicle dumping are particularly prevalent within the catchment and pose a risk to water quality.

The remainder of land in the catchment is privately owned, with the majority near the southern boundary of the catchment. Land uses on these properties include several orchards, a cold store, a general shop, a fuel station and a garage. Several parcels of land are owned freehold by the Department of Water (Department) and Water Corporation.

Department of Water2


The following strategies are recommended to protect the Victoria Reservoir drinking water source:

• all Crown land should be managed for Priority 1 source protection, except for reserve 26315, managed by Kalamunda Shire as a golf course, which should be Priority 2;

• private land should be managed for Priority 2 source protection, except for the shopping area on the corner of Pickering Brook Rd and Canning Rd, including a fuel station, automotive workshop and general store, which should be managed for Priority 3 source protection;

• the catchment, including the Reservoir Protection Zone and Priority 1 classification area, should be recognised in the relevant land planning strategies and schemes, specifically the Shire of Kalamunda, City of Gosnells and City of Armadale Town Planning Schemes; and

• best management practices for current or approved land uses in the catchment should be implemented.



1. IntroductionThe Victoria Reservoir was the first permanent source of drinking water for the Perth metropolitan area and was constructed in 1891 on Munday Brook, a tributary of the Canning River, approximately 25 kilometres east of Perth. In 1990 the original dam was decommissioned, and a new dam was constructed in 1991 approximately 110 metres further upstream. The reservoir remains a strategic source of public drinking water for the Integrated Water Supply System (IWSS) which supplies water to Perth, Mandurah, Pinjarra, Harvey and the Goldfields agricultural regions.

The majority of the Victoria Reservoir catchment falls within the Shire of Kalamunda, with small sections in the Cities of Gosnells and Armadale. Refer to Figure 1 for the location of the reservoir and its catchment and Figure 2 for the administrative boundaries.

The objective of this Plan is to recommend protection strategies to ensure land uses and activities in the catchment are managed to protect the water quality of this important drinking water source. The Plan will be reviewed on a five year rotating cycle.

1.1 Water supply systemThe Victoria Reservoir has a capacity of 9.5 gigalitres, and a full supply level of 202 metres Australian Height Datum (AHD). It is an important source of water for the Integrated Water Supply System (IWSS) and also supplies water locally to the foothills, which includes Kalamunda and its adjacent suburbs.

The Victoria Reservoir is currently supplemented with water from Bickley Reservoir via a pumpback scheme. The volume of water that the pumpback provides ranges between 30 percent to 40 percent of the total water taken from Victoria Reservoir used to supply the Perth metropolitan area. Since 2002 this volume has increased due to chlorinated groundwater from the metropolitan water supply system being transferred into Bickley Reservoir (thus increasing the volume of water available from Bickley).

1.2 Existing water source protectionThe Victoria Reservoir Catchment Area was proclaimed in 1923 under the Metropolitan Water Supply, Sewerage and Drainage (MWSSD) Act 1909 to ensure protection of the water source from potential contamination. Refer to Figures 2 or 3 for the existing Victoria Reservoir Catchment boundary.

The catchment area for the Bickley Reservoir has also been proclaimed under the MWSSD Act. Refer to the Bickley Reservoir Catchment Area Drinking Water Source Protection Plan for details on source protection issues in this catchment.

1.3 Water resource allocationThe Department of Water is responsible for the allocation and licensing of any water use in areas proclaimed as Surface Water or Groundwater Areas under the Rights in Water and Irrigation (RIWI) Act 1914. Water licence allocations are aimed at ensuring equitable use of the State’s water resources between competing interests and protection of the long term security of those resources.



The Victoria Reservoir and its catchment area has been proclaimed under the Rights in Water and Irrigation (RIWI) Act 1914 as the Victoria Reservoir Surface Water Area.

1.3.1 Current allocation licence

The Water Corporation has an allocation licence for the Victoria Reservoir, which permits the diversion of up to 4.3 gigalitres per annum from Munday Brook.

1.3.2 Future water supply

The Victoria Reservoir will continue to be used to supply water to the Integrated Water Supply System.

2. Catchment description

2.1 ClimateThe Perth region has a Mediterranean climate, characterised by warm dry summers and mild wet winters. The average annual precipitation for the catchment is approximately 906 millimetres, with the majority of this rainfall falling between the months of May and September.

Over recent decades Western Australia has experienced an unprecedented and mostly unpredictable shift in its climate. In the south-west, changes in climate (as a result of the greenhouse gas effect and natural variability) have resulted in a ‘drying climate’, with a 10-20 percent decline in winter rainfall since 1975. As rainfall is a key driver for the environment, such changes have significant implications for our limited water resources.

2.2 Physiography and vegetationThe Victoria Reservoir catchment is located on the Darling Scarp which forms the western boundary of the Darling Range. This area forms part of the Archaean Yilgarn Block, which consists mainly of granite, gneisses, migmatite and doleritic intrusions (King and Wells, 1990).

The Murray, Yarragil and Dwellingup vegetation type complexes cover the majority of the catchment. Much of the land is open forest or woodland dominated by several Eucalyptus species. Private land exists along the southern boundary of the catchment and has been cleared for agriculture purposes and other uses.

The major valleys of the Victoria catchment are defined as the Murray soil type, which is characterised by red and yellow soils. The minor valleys consist of the Yarragil soil type, which includes sandy gravels on the slopes, and swampy floors.

The lateritic uplands are represented predominantly by the Dwellingup soil type, which forms a gently undulating landscape. This soil type consists of duricrusts on the ridges, and sands and gravels in shallow depressions. There are also some smaller areas of the Cook soil type, which includes hills mantled by laterite with some rock outcrop.

2.3 HydrologyThe catchment for Victoria Reservoir covers an area of 37 square kilometres with Munday Brook the major tributary supplying the reservoir. The long term average yield entering Victoria Reservoir via catchment inflows is 3.1 gigalitres per year (1994-2001) and includes an average input of 1.4 gigalitres via the Bickley pumpback connection.

Since 2002, Bickley Reservoir has been used to transfer chlorinated groundwater to Victoria Reservoir. This has increased the total volume of water supplied via the pumpback from Bickley to between 25 percent and 50 percent of the total water volume held in the Victoria Reservoir.



3. Water quality and treatment

3.1 Water qualityA wide range of chemical, physical and microbiological properties can affect the health and aesthetic quality of drinking water. The Water Corporation monitors the raw (source) water quality from Victoria Reservoir consistent with the Australian Drinking Water Guidelines (ADWG). For details of the raw water quality analyses undertaken by the Water Corporation (between 1999 and 2004) refer to Appendix 1.

The Water Corporation undertake catchment sampling according to their operational guidelines. As part of the catchment water quality sampling program, risks are identified and sampling carried out downstream of any potential contamination source as well as sampling on each major feeder stream and the reservoir itself. Point and non-point source microbiological risks have been identified in the Victoria Catchment Management Strategy and a recommended sampling program for raw water, the reservoir and catchment streams has been defined.

3.2 Water treatmentThe water abstracted from the Victoria Reservoir is disinfected (chlorinated), and fluoridated before supplying the Integrated Water Supply System (IWSS). Chlorination is the primary barrier used against unwanted bacteriological activity to ensure good quality public drinking water. Under high turbidity water conditions chlorination can be ineffective in treating raw water for microbiological contamination (NHMRC and ARMCANZ, 1996). As such the Water Corporation monitors turbidity concentrations in raw water supplies.

Pumpback from Bickley to the Victoria Reservoir only operates during the winter months when the Victoria Reservoir is ‘offline’. In order to facilitate mixing and dilution of the water transferred from Bickley, Victoria remains offline for approximately one month after the cessation of pumpback activities.

Although reservoir storage and disinfection by chlorination generally removes contamination to provide safe drinking water, treatment processes alone cannot and should not be relied upon. Where possible, contamination should be prevented or reduced through appropriate land use or activity controls in the catchment area. This approach is endorsed by the Australian Drinking Water Guidelines (NHMRC and ARMCANZ, 1996) and reflects a ‘catchment to consumer’ multiple barrier approach for the provision of safe drinking water to consumers.

Western Australia has adopted this approach in the management of its public drinking water catchment and it is also recommended for the protection of private water supplies.



4. Land use

4.1 Current land useCurrent land use in the Victoria Reservoir catchment includes:

• land and forest management on Crown land;

• recreation on Crown land;

• rural and commercial land use on private land; and

• land management on Department of Water and Water Corporation freehold land.

Land use and tenure in the catchment are shown in Figure 2. The source protection area falls across the administrative boundaries of the Shire of Kalamunda, City of Gosnells and City of Armadale.

Native Title claims (Reference: WAG0142_98) exist over the land within the Victoria Reservoir Catchment Area. The claimants are represented by the South West Aboriginal Land and Sea Council.

4.1.1 Crown land - land and forest management

Approximately 90 percent of the Victoria catchment is under Crown ownership. An extensive area of the catchment is State forest (Number 54) which has been vested with the Conservation Commission of Western Australia and is managed by the Department of Conservation and Land Management (CALM).

State forest within the catchment has recently (2004) been reserved as national park following the Reserves (National Parks and Conservation Parks) Bill 2004. State forest is managed for the purposes defined in the Forest Management Plan 2004-2013 as conservation, recreation, timber production on a sustainable yield basis, water catchment protection and other purposes prescribed by the regulations. For further information on forest land management, refer to the Forest Management Plan 2004-2013 (Conservation Commission of Western Australia, 2004).

In addition to State forest on Crown land, Reserve 21172 (vested with Water Corporation) consists of remnant vegetation and is used for the purpose of water quality protection of the Munday Brook. There is a golf course on Reserve 26315, vested with the Shire of Kalamunda.

A Special Lease, granted under the State Agreement Act to Alcoa of Australia (Alcoa) in 1961, covers part of the Crown land area. This lease permits Alcoa to extract bauxite from the area, but includes a responsibility to ensure the environmental value of the area is protected and mine sites are rehabilitated. As yet, no mining activity has occurred in the catchment, and there are currently no plans to mine in the immediate future.

Management of State forest by CALM is in accordance with the purpose of State forest and includes fire management (for biodiversity conservation and the protection of assets) and the control of feral animals (fox baiting and feral pig trapping). All feral animal control activities on land managed by CALM must be coordinated by CALM. In addition to State forest, CALM also has management responsibilities for unallocated Crown land. Such responsibilities include the promotion of conservation of biodiversity, fire prevention, weed and animal control, harvesting of flora and forest produce and management of recreation.



Licences for commercial firewood collection are issued by CALM, with collection from State forest facilitated through the commercial harvesting of the forest by the Forest Products Commission. The collection of firewood by the public is not permitted within nature reserves, national parks or conservation parks except in designated firewood areas in State forest and timber reserves. Apiaries (nine sites), wildflower picking and seed collection also occur in the State forest and are licensed by CALM. The catchment and reservoir are also occasionally used for research projects.

Management of forest on other tenures includes softwood timber production on a small plantation in the catchment.

4.1.2 Crown land – recreation

Given the relatively unrestricted access to the Victoria catchment, numerous authorised and unauthorised recreational activities occur there.

Authorised activities include the Kattamorda Heritage Trail, an established walk trail managed by CALM that passes through the catchment to the north of the reservoir. The Munda Biddi long distance mountain bike trail, opened in 2004, also passes through the back of the Victoria catchment along Carinyah Road. It is likely that this track will increase visitor numbers in the catchment but, providing visitors keep to the designated trail, should have minimal impact.

A golf course and a shooting range are located inside the catchment. The golf course is affiliated with the Pickering Brook Sports Club that lies on the catchment boundary. Some irrigation of the golf course occurs from bore water sourced on site, but the fairways are not watered. The shooting range in State forest east of Canning Road in the north of Victoria catchment is operated by a small rifle club that uses the area on weekends.

Unauthorised recreational activities include fishing and marroning, camping and off-road vehicle use. Rubbish and vehicle dumping are particularly prevalent in the Victoria catchment.

4.2 Private landPrivate land comprises approximately 260 ha of the total catchment area (of 3686 ha) and can be found mostly near the southern boundary. Land use in this area is primarily agricultural (orchards). The remaining private land in the catchment is characterised by smaller properties close to the northern boundary and land uses include orchards, a general store, a hairdresser, a fuel station (closed) and automotive workshop, and cold store. All commercial land uses occur in the north of the catchment (refer to Figure 2).

4.3 Department of Water and Water Corporation freehold land

The Department of Water and the Water Corporation have freehold ownership of several properties in the catchment consisting of small cleared or partly revegetated blocks. The Water Corporation has vested responsibility for their management.

Land management by the Water Corporation includes fire management such as prescribed burning and maintenance of firebreaks. Prescribed burning is done in conjunction with the relevant shire authorities.

These freehold properties are frequented for the purposes of illegal recreation, often resulting in the dumping of stolen cars and rubbish.

Figure 3. Victoria Reservoir catchment area, Reservoir Protection Zone and Priority Classifications



5. Public Drinking Water Source Area protection

The protection of Public Drinking Water Source Areas (PDWSAs) by the Department of Water is consistent with government policy and involves three key elements:

• the proclamation of the PDWSA;

• the determination of ‘priority classification areas’ for land within the PDWSA; and

• the establishment of a Reservoir Protection Zone within the PDWSA.

The preparation of this Drinking Water Source Protection Plan forms part of the ‘multiple barrier’ approach for the protection of public drinking water sources from potential contamination. The strategies used to protect PDWSAs in this Plan recognise the rights of existing and approved land uses and activities.

5.1 Proclaimed areaAreas ‘proclaimed’ for drinking water purposes include Underground Water Pollution Control Areas (UWPCA), Water Reserves and Catchment Areas declared under the Metropolitan Water Supply, Sewerage and Drainage Act 1909 or the Country Areas Water Supply Act 1947.

The Victoria Reservoir Catchment Area was proclaimed in 1923 under the Metropolitan Water Supply, Sewerage and Drainage Act. An amendment to the original boundary has been adopted so that it will more accurately represent the physical catchment boundary.

The proposed Victoria Reservoir Catchment Area is shown in Figures 2 and 3.

5.2 Priority classificationLand within PDWSAs is allocated one of three priority classifications (1, 2 or 3). The classification looks to prioritise areas for the protection of water quality and has been defined using present land use information, existing or approved land zoning, ownership, the importance of the water source, and the vulnerability of the water body. Each priority classification allows different levels of activity according to the degree of risk to the water resource. Additional constraints may also apply in zones closest to the point where drinking water is harvested or stored. These areas are known as Wellhead Protection Zones (WPZ) or Reservoir Protection Zones (RPZ).

Further details of the priority classifications and the detail of land use compatibility with each priority classification are provided on the Department’s Internet site at www.drinkingwater.water.wa.gov.au.

The majority of the land in the Victoria catchment is Crown land. Where possible Crown land should be managed for Priority 1 (P1) source protection. The objective of a P1 classification is risk avoidance for the protection of water quality. A P1 source protection classification is appropriate for Crown land as:

• the Victoria Reservoir Catchment Area is an important source of public drinking water for the Integrated Water Supply System, and should be afforded the highest level of protection;



• the land is State forest or owned freehold by State government agencies; and

• most existing land use practices are compatible with P1 source protection, or can be managed for P1 source protection with the use of best management practices.

The golf course (located on Crown land Reserve 26315) on the northern boundary of the catchment should be managed for Priority 2 source protection to minimise any potential water quality impacts (see Table 1). The objective of Priority 2 classification is to protect water quality according to the principle of risk minimisation.

Private land in the Victoria catchment should largely be managed for Priority 2 (P2) source protection. The cold store on Canning Road should also be managed for P2 source protection due to the proximity of the property to streams and its drainage from the property down the road reserve. A P2 source protection classification is appropriate for these areas as:

• the Victoria Reservoir is a strategic source of public drinking water for the Integrated Water Supply System; and

• existing land use practices are compatible with P2 source protection with implementation of best management practices.

The shopping area on the corner of Pickering Brook Road and Canning Road which includes a fuel station, an automotive workshop and general store, should be managed for Priority 3 (P3) source protection. Discussions with the owner should continue to investigate the option of permanent removal of the fuel station structures as the underground fuel tanks pose an unacceptable risk to water quality (see Table 1). Should dismantling of the structures not be deemed appropriate regular environmental assessments of the site should be conducted.

5.3 Reservoir Protection ZoneTo protect the reservoir from immediate risks to water contamination, a prohibited zone (also known as a Reservoir Protection Zone (RPZ)) extends for 2 km from the top water level of the reservoir and includes the reservoir itself (refer to Figure 3). Within these zones, by-laws prohibit, restrict and regulate land use and human activities to prevent water source contamination. For further details on RPZs refer to the Department’s Internet site at http://drinkingwater.water.wa.gov.au.

There are no trails or private land within the RPZ for the Victoria catchment, with only State forest or freehold land falling within the 2 km RPZ area.



6. Management of water quality risks

6.1 Land use planningIt is recognised under the State Planning Strategy (Western Australian Planning Commission, 1997) that the establishment of appropriate protection mechanisms in statutory land use planning processes is essential to secure the long term protection of water sources.

It is therefore recommended that the Metropolitan Region Scheme and the Town Planning Schemes for the Shire of Kalamunda, City of Gosnells and City of Armadale recognise priority classification areas and protection zones assigned to land in the Victoria Reservoir Catchment Area. This is consistent with the Western Australian Planning Commission’s Statement of Planning Policy 2.7 Public Drinking Water Source Policy (June 2003).

The Department of Water provides advice on the compatibility of land uses within the proposed priority classification areas based on the guidance document Land Use Compatibility in Public Drinking Water Source Areas (see www.drinkingwater.water.wa.gov.au/wqpn). Development and work proposals in the catchment that are inconsistent with the land use table should be referred to the Department’s Swan Goldfields office for assessment and recommendation.

6.2 Surveillance and by-law enforcementThe Department of Water has delegated the responsibility for surveillance and associated by-law enforcement in the Victoria Reservoir catchment to the Water Corporation who report annually to the Department. As the catchment area has been proclaimed under the MWSSD Act, the by-laws of this Act can be used to control potentially contaminating activities within the catchment.

By-law enforcement, through on-ground surveillance of land uses and activities, is a critical mechanism in protecting the quality of drinking water sources. Water Corporation Ranger communication with visitors to the catchment also assists in increasing public awareness of the need to protect drinking water quality.

The use of signs and other informative material is also an important component of water quality protection for those who visit the catchment and for landowners in the catchment.

6.3 Best management practicesTo help protect water quality in the catchment, best management practices for land use activities are encouraged. These are often in the form of industry codes of practice and environmental guidelines. Guidance documents are usually developed in consultation with industry groups, producers and State government agencies.

Best management practices can be developed for an individual enterprise or have a local or regional focus and must consider the full range of economic, social and environmental issues associated with land, water and vegetation use. Development of best management practices must also take into consideration the needs and concerns of users, consumers and the wider community (ARMCANZ & ANZECC, 1996).



The potential risks to water quality from existing land uses can be reduced by the implementation of best management practices. For example, fencing to control stock access to watercourses, retention of vegetation along streamlines (riparian zones), appropriate pesticide, herbicide and fertiliser application practices (as detailed in Statewide Policy No.2 Pesticide Use in Public Drinking Water Source Areas (WRC, 2000)) and septic tank management. The implementation of best management practices for land use activities in the catchment is encouraged to protect water quality.

Similarly, the potential risks to water quality associated with forestry activities can be managed by the adoption of best management practices such as appropriate road construction and maintenance, use of sumps or drains for sediment control, and appropriate retention of buffer zones along watercourses. Refer to the Manual of Management Guidelines for Timber Harvesting in Western Australia (CALM, 1999a) and the Department’s Water Quality Protection Note Buffers to Sensitive Water Resources.

The implementation of best management practices for land use activities in the catchment is encouraged and expected to assist in protecting water quality.

A reference list of best management practice documents for some of the catchment activities in Victoria Reservoir is provided in Appendix 2.

6.4 Emergency responseDischarge of chemicals during unforeseen incidents and use of chemicals during emergency response can result in the contamination of water sources. The Shire of Kalamunda, City of Armadale and the City of Gosnells Local Emergency Management Advisory Committees through the Cannington and Midland Emergency Management Districts should be familiar with the location and purpose of the Victoria Reservoir Catchment Area. A locality plan should be provided to the Fire and Rescue Services headquarters for the HAZMAT Emergency Advisory Team. The Water Corporation should also have an advisory role in any HAZMAT incident in the catchment area.

Personnel who deal with WESTPLAN - HAZMAT incidents within the area should be given ready access to a locality map of the Victoria Reservoir Catchment Area. These personnel should receive training on the potential impacts of spills on the surface water resources.

6.5 Recommended protection strategiesTable 1 identifies the potential water quality risks associated with existing land uses in the Victoria catchment, and recommends protection strategies to manage these risks.

The potential water quality risks were identified and resulting management priorities designated using a risk assessment process. Strategies have been developed in line with the Australian Drinking Water Guidelines (NHMRC and ARMCANZ, 1996).

The recommended protection strategies balance the need to protect water quality now and in the long term with the rights of landholders to continue to utilise their land for approved use.

Recommendations1. Amend the existing Victoria Reservoir Catchment Area under the Metropolitan Water

Supply, Sewerage and Drainage Act 1909 (Department of Water).

2. The Metropolitan Region Scheme and the Town Planning Schemes for the Shire of Kalamunda, City of Gosnells and City of Armadale should recognise priority classification areas and protection zones assigned to land in the Victoria Reservoir Catchment Area (Shire of Kalamunda, City of Gosnells and City of Armadale).

3. Ensure that the Water Corporation are advised of development and works proposals in the Victoria Reservoir Catchment Area that are likely to impact on water quality. Proposals that are inconsistent with the Department’s Land Use Compatibility Table and Water Quality Protection Notes and Guidelines should be referred to the Department of Water for assessment and recommendation (Local and State government agencies and all key stakeholders).

4. Develop a management plan for shire roads and main roads that addresses water quality protection objectives. The development of new roads through the catchment should not be promoted (Main Roads WA, Shire of Kalamunda, City of Gosnells and City of Armadale).

5. Provide information and encourage private landowners to adopt best management practices (Department of Water and Water Corporation).

6. Work with the owner of the old fuel station to ensure the underground storage tanks are removed and clean-up of any contaminated soil occurs. If this is not possible, environmental assessment around the storage tanks should be conducted on a regular basis (Department of Water, Department of Environment and Water Corporation).

7. Ensure that personnel dealing with WESTPLAN – HAZMAT incidents in the Victoria Reservoir Catchment Area are given ready access to a locality map of the catchment area and training to understand the potential impacts of spills on the surface water resource (Water Corporation).

8. Ensure that signs are installed and maintained along the boundaries of the catchment area and proposed Reservoir Protection Zone to define the areas and to promote public awareness of the importance of protecting drinking water quality (Water Corporation).

9. Continue the implementation of the catchment surveillance program and associated by-law enforcement in the Victoria Reservoir Catchment Area (Water Corporation).

10. Develop and implement environmental management plans for any recreational events within the catchment under guidance of the Water Corporation (WC). The WC should audit plans after each event. Any new proposals would also require such a plan (Organisers of approved recreational events).

11. Ensure designated picnic areas are outside the Reservoir Protection Zone and include appropriate facilities with no access to the water body (Local and State government agencies).



12. Develop environmental management strategies with both the rifle range and golf course site operators, and encourage the use of best management practices, and management of spent projectiles. After the establishment of these strategies catchment Rangers should meet biannually with the operators to ensure water quality protection measures are in place and that they are working effectively (Water Corporation, Department of Environment and Department of Water).

13. A coordinated inter-agency plan is developed to reduce rubbish dumping in the catchment (Department of Water and Water Corporation).

14. Stream zones and other areas of this catchment in Water Corporation, the Department of Water or other government ownership are assessed for the need for rehabilitation, and rehabilitation with native species carried out where necessary (Water Corporation, Department of Environment and Department of Water).

15. A Drinking Water Source Protection Plan for the Victoria Reservoir catchment should be developed and implemented by Department of Environment, Department of Water and Water Corporation to ensure water supplied to the Integrated Water Supply System is of the highest achievable standard (Department of Water).

16. Strategies detailed in Table 1. Land Use, Potential Water Quality Risks and Recommended Strategies are adopted (Local and State government agencies).

17. A review of this plan is undertaken within five years to determine the status of the water reserve and level of implementation of these recommendations (Department of Water).

AppendicesAppendix 1 Water Quality Results provided by the Water Corporation

Appendix 2 Best Management Practices documents for activities in PDWSAs



APPENDIX 1

Water Quality Results provided by the Water CorporationThe Water Corporation has monitored the raw (source) water quality from Victoria Reservoir in accordance with the Australian Drinking Water Guidelines (ADWG) and interpretations agreed to with the Department of Health. The raw water is regularly monitored for:

a. Health related characteristics• Microbiological Contaminants• Health Related Chemicals

b. Aesthetic characteristics– (Non-health related)

Following is data representative of the quality of raw water in Victoria Reservoir. In the absence of specific guidelines for raw water quality, the results have been compared with ADWG values set for drinking water. Results that exceed ADWG have been shaded to give an indication of potential raw water quality issues associated with this source.

It is important to appreciate that the raw water data presented does not represent the quality of drinking water distributed to the public. For information on the quality of drinking water supplied in the Perth Region refer to the most recent Water Corporation Drinking Water Quality Annual Report at: http://www.watercorporation.com.au/dwq/index.cfm.

Health Related Characteristics – Victoria Reservoir Raw Water• Microbiological Contaminants

Microbiological testing of raw water samples is conducted on a weekly to monthly basis, particularly during summer and autumn. Thermotolerant coliform counts are used as an indicator of the degree of faecal contamination of the raw water from warm-blooded animals. A count less than 20 colony forming units (cfu) per 100 millilitre (mL) is typically associated with low levels of contamination and is used as a microbiological contamination benchmark (WHO, 1996).

During the review period of January 1999 to October 2004 the raw water in Victoria Reservoir was sampled for thermotolerant coliforms 226 times. Positive thermotolerant counts were recorded in 56 percent of samples. Five percent of the positive samples had thermotolerant coliform counts greater than 20 cfu/100 mL.

These percentages are higher than in some of the larger more pristine hills drinking water catchments further from population centres, but lower than some of the catchments with greater human impact. This is a cause for concern as any positive result in disinfected drinking water is considered an exceedence of the ADWG guideline level and it implies that there are insufficient barriers within the catchment to prevent contamination of the raw water. These results show the importance of disinfection and will focus the ‘catchment protection’ for this reservoir on those land uses or activities that have the potential to impact bacterial contamination.



Parameter Units ADWG Health Guideline Value*

Victoria ReservoirRange Median

MetalsBarium mg/L 0.7 0.017-0.06 0.02Boron mg/L 4 0.02-0.036 0.03

InorganicsFluoride mg/L 1.5 <0.1-0.35 <0.1

Nitrate + Nitrite (as N) mg/L 11.3 0.4-0.4 0.04* A health guideline value is the concentration or measure of a water quality characteristic that, based on present knowledge, does not result in any significant risk to the health of the consumer over a lifetime of consumption.

The above parameters have been detected in the raw water at concentrations well below ADWG health guideline values, and pose no health concern. Monitoring of health parameters is ongoing.

Turbidity can affect microbiological activity in drinking water, by protecting pathogenic micro-organisms from the effects of disinfection, promoting bacterial growth and exerting a significant disinfectant demand. A turbidity of less than one NTU is desirable for effective disinfection. Adequate disinfection may be achieved at higher turbidity levels (particularly up to the guideline level of five NTU) however the efficiency of disinfection decreases with increasing turbidity. As such, the generally low turbidity levels recorded at Victoria Reservoir (see Aesthetic Characteristics section below) ensure a relatively low risk associated with detected microbiological contamination, but it is important that this is maintained.

The WC also monitor for cyanobacteria (‘Blue Green Algae’) in drinking water catchments that are considered at risk of having elevated levels of cyanobacteria, for example catchments with a significant proportion of agricultural land or a history of high nutrient levels. The WC is guided by the National Protocol for the Monitoring of Cyanobacteria and their Toxins in Surface Fresh Waters (ARMCANZ, 2003). This document is currently only in draft and therefore the alert levels are yet to be finalised. The results of the first cyanobacteria monitoring on 28 July 2004 indicate that cyanobacteria counts and densities in Victoria Reservoir were well within health limits.

• Health Related Chemicals

Health related chemicals include inorganics, heavy metals, industrial hydrocarbons and pesticides. Health related chemicals that have been measured at detectable levels in the source between January 1999 and October 2004 are summarised in the following table. All values are in milligrams per litre (mg/L).



Aesthetic characteristics – Victoria Reservoir raw waterAesthetic water quality analysis for raw water from Victoria Reservoir is summarised in the following table. These values were taken from continual monitoring for the period January 1999 to October 2004. All values are in milligrams per litre (mg/L) unless stated otherwise. The water quality parameters that have on occasion exceeded the ADWG aesthetic guideline for supplied drinking water are shaded.
