OVERVIEW

This report is for Water Services activities for October 2018. Significant items in this period include:

No Lost Time Injuries occurred during October 2018.

The Mount Pleasant No.1 Reservoir Refurbishment Project was awarded the winner of the Asset Management Category at the IPWEAQ Excellence Awards held at the Gold Coast on 11 October 2018. An officer attended the AWA QWater’18 Conference on the Gold Coast from 1-2 November 2018 to present the paper.

Officers attended Victor Harbour in South Australia on 3 October 2018 for an operations benchmarking exercise. Our large sewage treatment plants, the Mackay North Water Recycling Facility (MNWRF) and Mackay South Water Recycling Facility (MSWRF), currently operated by Downer, will come back under MRC control on 1 July 2019. As part of the handback conditions, both plants must be in good condition for their age. Victor Harbour was chosen because it's facility is about the same age but also designed, constructed and operated in much the same way (e.g. Design Build Operate) as MNWRF and MSWRF. The visit provided valuable bench marking information.

An officer attended the Customer and Industry Leadership Committee Meeting in Canberra on 9 October 2018 which was hosted by the Water Services Association of Australian.

Representatives from Gympie Regional Council Water Department visited with Water Network, for two days, on 10 & 11 October 2018 to gain an understanding of how Mackay Water is using Assetic. Gympie Regional Council is currently implementing Assetic as an asset management and maintenance system.

Corporate Communications has been working in conjunction with Water Networks to design and install six Water Refill Stations as part of the National Water Week Celebrations. The locations of stations installed in high traffic areas include: Botanic Gardens, John Breen Park, Sarina Field of Dreams, Mirani Railway Playground, Quota Park, Blacks Beach Park. An unveiling of the Water Refill Station at the Botanic Gardens occurred on 22 October 2018.

Whitsunday, Isaac, Mackay (WIM) Water Alliance has been successful in applying for funding through the Queensland Water Regional Alliance Program (QWRAP) for a Learning & Development Project Officer. The officer will be responsible for developing a plan to assist in the implementation of the Water Industry Worker (WIW) framework across Cairns, Burdekin, Whitsunday and Mackay Regional Councils and Townsville City Council.

Officers visited Logan City Council’s Laboratory and Queensland Urban Utilities Laboratory in Brisbane on 26 October 2018. Logan City Council has just recently completed building a new laboratory and provided some useful insights into what went well and what didn’t. Queensland Urban Utilities laboratory is the largest Water Utility laboratory in Queensland and valuable information was gained reviewing the systems and processes used to manage a high workload.

An officer attended a Sewerage & Water Environmental Advisory Panel (SWEAP) Meeting held by the QLD Water Directorate in Brisbane on 31 October 2018.

Brief overview of recycled water usage and availability via the Mackay Water Recycling Facility (MWRF) Reuse Scheme:

a) 2,270 ML used for the financial year to date

b) Recycled Water Storage 3 (RWS3) is at 40% capacity (880 ML) of which approximately 680 ML is accessible

Page 4


c) Recycled Water Storage 2 (RWS2) is at 50% capacity (265 ML) of which approximately 165 ML is accessible

d) Current total usage is approximately 60 ML per day

e) Inflow from Mackay South Water Recycling Facility (MSWRF) amounts to approximately 12 ML per day

3.2. Request Types

The following chart displays a summary of the customer request types received for the month.


The number of requests received in October 2018 was 333 and the majority of the requests were for Water Leak Services; i.e. 162 requests.

When a customer lodges a request via the Call Centre, it is sometimes not reflective of the actual problem. Therefore, the following graph is included showing the actual work undertaken. The numbers of Customer Requests will not exactly match the number of actions undertaken mainly due to multiple customers reporting the one issue and the timing of completed work (i.e. a request being received at the end of one month but being actioned at the start of the next month). As the majority of Customer Requests are water related, the following graph is a breakdown of the action type for the current month based on the Customer Requests above, along with the yearly trend for Water.

3.3. Plumbing Applications

In accordance with the Plumbing and Drainage Act, a plumbing application is required for all new or modifications to plumbing installations. A plumbing application must be lodged to Local Government. Water Services has a regulatory time frame of 20 business days to assess a plumbing application. An internal target of five business days has been set for all residential plumbing applications.


The number of Plumbing Applications approved decreased from 61 in September 2018 to 46 in October 2018. The Approval Turnaround Time is at two days which is inside the five-day target.

3.4. Trade Waste Approvals

There is an ongoing program for undertaking trade waste assessment and licensing applicable businesses that discharge trade waste. As part of the trade waste assessment process a temporary Trade Waste Approval is established while the formal approval process is undertaken. The table below summarises the number of Trade Waste Approvals for the Mackay region.


Six new Trade Waste Approvals were provided to businesses during October 2018 after the Trade Waste requirements were completed. These businesses were: three for a change of ownership and three new businesses.

3.5. Annual Trade Waste Activity

Annual targets are set for the Trade Waste team with respect to licensing trade waste businesses. The target has been set at 250 for new licensed businesses and audits completed by June 2019. The following chart shows the actual approvals, temporary approvals and audits achieved and the number of the target remaining.


Six Approvals were issued, and eight audits were conducted during October 2018.

3.6. Building Over Adjacent Sewers

Building Over Adjacent Sewer (BOAS) applications are lodged where the construction of a structure is proposed within close proximity of a sewer main. The application is assessed against Queensland Development Code Mandatory Part 1.4 with council reviewing applications that do not comply with acceptable solutions identified in the code. Building over sewer applications are assessed within a target timeframe of 20 business days.


One BOAS referral was received in October 2018. Plumbing Inspectors continue to handle enquiries and provide information on infrastructure locations and general information regarding the Queensland Development Code.

3.9. Leak Detection Notifications

Leak Detection notifications are sent to customers, when a leak on their property is identified that is greater than 10 litres per hour (L/h). Follow up notices are sent to residents, monthly for a three-month period after the initial notification.


Residential

The number of new leaks identified during October 2018 for residential customers was 2,302, an increase from last month, and the number of meters with leaks increased to 794. The number of leaks ceased during the period has increased to 2,294 indicating that residents fixed the leak.

Non-Residential

The number of new leaks for non-residential customers was 498 (i.e. a decrease), however, the number of meters with leaks increased by 300 for non-residential customers. The number of leaks ceased for non-residential customers decreased to 468 indicating that the non-residential customers have yet to fix the leaks. Due to the complexity of some non-residential properties (multiple tenants, large properties, etc), leaks are difficult to identify and locate and fixing the leaks for non-residential customers is sometimes not cost effective.

The Average Leak Days (Current Leaks) identified during October 2018 for customers has slightly decreased for residential and slightly increased for non-residential. The difference between non-residential and residential for current leak days is 58 days. The Average Leak Days (Ceased Leaks) show that the residential customer has leaks repaired within 9 days on average, whereas the non-residential customer takes 11 days to have leaks repaired on average. Considerable effort is undertaken with non-residential customers to encourage attention to fix the identified leaks, however, some of these leaks are very difficult to track down and are not cost effective to rectify.

ASSET MANAGEMENT 4.1. Surface Water Raw Water Storage Capacities

Water is sourced from a combination of surface and groundwater sources. With the exception of Middle Creek Dam, the storage facilities are owned and operated by SunWater. Middle Creek Dam is under Council’s control. The water stored in each of the storages is detailed below.


Mirani Weir, Marian Weir and Dumbleton Weir are at full capacity. Teemburra Dam is at 88% capacity. Middle Creek Dam and Peter Faust Dam are at 50% and 62% capacity respectively.
