Water: Recycled but still not grey

Narrandera Shire Council’s recycled water system is operational and providing raw water to customers and Council facilities from the town’s bore system, but the Council is not currently supplying recycled effluent (grey) water.

Narrandera Shire Council’s recycled water system is operational and providing raw water to customers and Council facilities from the town’s bore system, but the Council is not currently supplying recycled effluent (grey) water.

Six years ago the Council completed the installation of a raw water and effluent re-use scheme, which has been providing up to 9ML per day of relatively inexpensive raw water to key public recreational areas in Narrandera ever since, thus reducing the load on the potable water supply.

However, Council has been unable to utilise the effluent re-use component of the scheme as the treatment plant does not consistently produce effluent of sufficient quality to allow it to be irrigated on active sporting fields. Improvements to the treatment plant are planned including an upgrade of the UV and filtration system. Works are currently being undertaken at the plant to analyse and establish the appropriate effluent combination to ensure the treated effluent water will be of consistently high quality if the Council decides to supply treated water to these facilities.

When completed Council’s recycled water management plan will be reviewed and submitted for approval by the NSW Office of Water. This administrative process is required prior to effluent entering the system.

It has also been stated that using treated water will increase the costs of water and Council will need to create a usage plan that meets all of the safety requirements associated with treated water usage.

Once these works are carried out the plant should be capable of producing 1ML per day to add into the system. Facilities currently using recycled water include Marie Bashir Park, the Narrandera Memorial Gardens, Narrandera Sportsground, Narrandera High School and Narrandera Racecourse.

The Council aims to expand supply for usage of the raw water system to further facilities and public spaces in the township to enhance vegetation. The Council’s effluent re-use project was due for completion in 2012, with the five kilometre trunk pipeline started at the sewerage treatment works and terminating at the Golf Course.

At that time a former Council Technical Services Director stated that the effluent treatment plant was operational and Council was busy fulfilling the verification process with the Department of Water to get the plant operational.
