The Waikerie Community Wastewater Management System
May 2008
United Utilities Australia (UUA) has partnered Loxton Waikerie Council, located in South Australia’s Riverland, in the development of an affordable and environmentally sound, wastewater management scheme.
The scheme was essential because wastewater treatment lagoons currently in use are located on a flood plain and now overloaded. Both the EPA and the Department of Health in South Australia had raised concerns about these issues.
Future growth of the Waikerie township cannot proceed until new wastewater treatment infrastructure is commissioned.
UUA in collaboration with Council developed a proposal which included :
- Construction of a Class B package wastewater treatment plant allowing reuse of treated effluent in the irrigation of the local golf course;
- Upgrade of an existing pump station;
- Nine km 200mm pipeline to the disposal site;
- 40 ML capacity lined recycled water storage lagoon;
- Disposal of recycled water via an existing irrigation network.
Benefits
After detailed reviews Council determined that this scheme was by far its preferred option in that :- It provided a beneficial use for treated water which would substitute for water currently drawn from the River Murray;
- It was sustainable;
- The scheme could be augmented to cater for township growth including the opening up of new residential subdivisions.
Project Delivery
UUA then assumed responsibility for all aspects of project delivery including preparation of final design and tender documentation, project approvals, calling tenders which were also evaluated by Council and construction.
This is currently well advanced and the scheme is expected to be commissioned by the middle of 2008.
A purpose built aerated biological treatment plant has been sized to cater for a population of up to 2400 prior to augmentation. It will provide treated water that complies with the Department of Health and Environment Reclaimed Water
Guidelines for Class B treated effluent.
The plant will be operated in accordance with Environment Protection Authority and Department of Health approvals with regular sampling undertaken to verify performance. A long-term operations contract is currently being negotiated.
Capital cost of the project is $3.6m.
Project Sustainability
Extensive irrigation modeling confirmed that there would be no negative impacts from the long term use of reclaimed water on the golf course.
The reclaimed water contains nutrients and phosphorous which will significantly reduce the need to apply fertilisers. This process will be controlled by a detailed irrigation management plan which includes regular monitoring of soil samples
and ground water.
