1 INTRODUCTION

The District Council of Yankalilla is seeking to engage a suitably qualified contractor to undertake maintenance services for the Normanville Community Wastewater Management System (CWMS), Wirrina Cove (CWMS) and Wirrina Cove Water Supply System.

This document outlines the guidelines, standards and scope of services required to be met by the Maintenance Contractor.

There are three major components of this Maintenance Contract:

Regular maintenance and servicing of the system components.

Emergency response.

Equipment repairs (subject to individual quotation and approval).

During the Maintenance Contract period District Council of Yankalilla will continue to operate the facilities and will receive initial emergency calls.

This Contract is for one year period with the extension for the next two years subject to the performance assessment.




2 BACKGROUND

2.1 Normanville CWMS

The Normanville CWMS utilises a combination of gravity drains and rising mains to collect and to transport effluent to Normanville – Yankalilla Waste Water Treatment Plant (WWTP) along Hay Flat Road. Recycled Class B water from the WWTP is then used for irrigation of the golf course and public spaces.

The CWMS system which services approximately 2000 connections within the Normanville area is currently owned and operated by the District Council of Yankalilla. The Normanville CWMS is comprised of:<

• Network

− STED gravity drains

− Full sewer gravity drains

− Rising mains

− 13 x Council operated pump stations

− 3 x privately operated pump stations (not included in this Contract)

• Normanville, Hay Flat Road WWTP (1.7ML/day)

− 2 x Sequencing Batch Reactor (SBR) tanks

− Sludge tank

− Sewage overflow tank

− Decant tank

− Disk filtration system

− Multimedia filtration

− Chlorine disinfection (to be upgraded in 2015/16)

− 3 x Storage tanks

− 2 x Inline munchers

− Septic sludge receival tank

− Sludge mixing tank

− V belt filter press

• Recycled water reuse

− Rising main to Links Bay Storage Lagoon (Golf Course)

− Rising main to Yankalilla Memorial Park Storage Tanks

− Pipe branch to Yankalilla Skate Park Storage Tank




Individual irrigation systems of Links Bay Golf Course and public spaces within Yankalilla Township (not included in this Contract)

Layout plans of the system can be found in Appendix A.

2.1.1 CWMS Network

The gravity network drainage system services the majority of allotments which then feed into 13 pump stations operated by Council and 3 privately operated pump stations. The majority of these pump stations are for STEDS (Septic Tanks Effluent Disposal Scheme). The Links Lady Bay stations are however full sewer.

The Normanville gravity drain network has been installed in the last 20 years, given this it is estimated that the system has adequate capacity to distribute flows throughout the network.

The pump stations allow for the transportation of effluent and sewage to the Hay Flat Road WWTP. The majority of the pump stations within the scheme feed to pump station No 3 along Jetty Road, which directly transfers effluent to the WWTP, with the exception of Links Lady Bay, which utilises a dedicated rising main to transport effluent to the WWTP.

2.1.2 Waste Water Treatment Plant

The WWTP was originally constructed in 1997 by Aeroflo, and was then upgraded by Factor UTB in 2009-2013. It has been identified that the capacity of the plant is 1.7ML/day with average flows entering the plant being approximately 360kL/day and peak flows 500kL/day during the summer period.

The treatment train consists of extended aeration system including two SBR reactors and a tertiary treatment system including disk and media filters and chlorine disinfection.

Waste activated sludge and septic sludge, which is received at the plant are mixed and dewatered using V belt filter press. Dewatered sludge is transported to a Council dump facility for disposal.

2.1.3 Water Reuse

The WWTP currently pumps treated water to a storage lagoon situated within the Links Lady Bay Golf Course and storage tanks situated within the Yankalilla Township.

All recycled water produced by the WWTP is used for irrigation of golf course and the Yankalilla public spaces.

The Yankalilla Memorial Park has two 244kL storage tanks that are fed by the recycled water pumping main. Irrigation from these tanks is controlled by Yankalilla Memorial Park Inc. The tanks are located at an elevation such that the irrigation system can be gravity fed.

The Skate Park has one 244kL storage tank fed by the recycled water pumping main. An irrigation pump is used to irrigate areas around the Skate Park.




2.2 Wirrina Cove Sewer Scheme

The Wirrina Cove CWMS comprises of full sewer gravity drains, pumping stations and rising mains, which convey flows to the WWTP along Wirrina Avenue.

The full sewer system is estimated to have capacity of 3200 and was designed to cater for original population of Wirrina Cove of 1661.

The Wirrina Cove CWMS consists of:7

• Wirrina Cove Sewer Network

− 150 ND gravity sewer network

− 5 x pump stations

− Rising mains

• Wirrina Avenue WWTP

− Raw Sewage Pump Station

− Demand Aeration Tank

− Intermittent Aeration Tank

− Sludge Tank

− Effluent Storage Tank

− Effluent Pump Station

• Post Treatment

− Storage Lagoon

− Two Evaporation Ponds

Layout plans of the system can be found in Appendix A and the equipment installed is listed in Appendix B.

2.2.1 Gravity Network

Gravity drains are used to collect full sewer from allotments prior to entering sump/pump stations which transport flows to the WWTP. Within the Wirrina Cove development there are 6 distinct gravity drain catchments:

1. Condos to Sunrise Court draining to Pump Station 1

2. Eagle Court, part Seaview Avenue and Bayview Avenue draining to

Pump Station 2

3. Part Seaview Avenue draining to Pump Station 3

4. Marina Avenue draining to Pump Station 4

5. Caravan Park draining to Pump Station 5

6. Wirrina Resort and unnamed Road 1 draining directly to the WWTP

Each pump station has a duty/standby pump arrangement.




All gravity drain infrastructure within the Wirrina Cove area is UPVC.

2.2.2 Rising Main and Pump Stations

The pressure network operates as a series of pump stations and rising mains. Pump Station 1 currently lifts sewage into the gravity network of Pump Station 2. Pump Stations 2 & 4 lift sewage into the gravity network of Pump Station 3. Pump Stations 3 & 5 deliver sewage directly to the Wirrina Waste Water Treatment Plant Raw Sewage Pump Station.

Rising main pipework is a combination of HDPE and UPVC pipes.

2.2.3 Waste Water Treatment Plant

The WWTP is located at the eastern end of Wirrina Avenue directly adjacent the Wirrina Golf Course. The treatment train is the Aeroflo system and consists of the Intermittent Aeration Tank and Demand Aeration Tank. There is also sludge tank to store and thicken waste activated sludge and treated effluent storage tank. All tanks are concrete tanks with concrete roofs. Once the waste water has been processed it is then pumped to a series of evaporation ponds situated within the Wirrina Golf Course directly adjacent the plant.

The WWTP has capacity to service the current population within Wirrina Cove, however if the population were to expand an upgrade to the current treatment plant would be required.

2.3 Wirrina Cove Water Treatment Plant Scheme

The water supply scheme within Wirrina Cove relies on the Wirrina Reservoir for supply of irrigation water and drinking water.

Raw water from the reservoir is pumped using two submersible pontoon pumps via a 200 mm diameter main into two raw water tanks located near the Water Treatment Plant (WTP) shed.

Raw water is then distributed for the irrigation and for the production of potable water. For irrigation purposes water is filtered via mechanical filters. The potable water treatment train consist of flocculation, sedimentation, media filtration and disinfection.

The Wirrina WTP consists of:-

Storage Tanks

2 x Raw Water Storage Tanks (external concrete)

Shandy Tank (external concrete)

2 x Treated Water Storage Tanks (external steel)

Treatment

2 x self cleaning screen filters (Irrigation water)

Flocculation tank and clarifier

Soda ash dosing for pH control

Polymer and alum dosing




Media filters

UV disinfection

Chlorine disinfection (sodium hypochlorite)

A detailed schedule of all the equipment associated with the Wirrina Water Treatment Plant can be found in Appendix B.

The WTP has been sized to supply water for original design peak flow demand based on the initial residential population of approximately 1600. The treatment plant has been identified to be operating within the range of 2.5L/s – 3L/s.

It should be noted that the equipment list included in Attachment B may not be complete. The list has been created by inspections of the plant and the review of available drawings and documentation.

Should the Contractor indentify equipment which is not on the list it should be added to the list by the Contractor.
