TREATED wastewater will continue flowing into Burrumbeet Creek while work is underway on the Ballarat North Wastewater Reclamation Plant.Last February, Central Highlands Water said the $30 million plant upgrade was complete but had not been approved, preventing it from releasing water into Lake Wendouree.Last month, it said work on the pipeline to send wastewater to the lake was complete, but the treated water was too salty to be released.But the water is considered of an acceptable standard to send down the Burrumbeet Creek and into Lake Burrumbeet, according to the Environment Protection Authority.The water being sent down Burrumbeet Creek is separate to the 600 megalitres allocated for Lake Wendouree.An EPA spokeswoman yesterday said the authority had to monitor the water sent down the creek.She said the limit on salt content for water being released into the creek was 1000mg/L. The authority's latest report showed salt levels of water being released into the creek were 700mg/L.The treated wastewater has about twice the salt content of Ballarat tap water. To meet the standard for Lake Wendouree, the agreement between CHW and the City of Ballarat requires that treated water be blended with stormwater, inflows or other fresh water sources.The EPA also requires it to be Class A standard.CHW spokeswoman Nicky McMaster said currently no Class A water was being produced from the Ballarat North treatment facility until works on the disinfection plant were complete.She said this was expected shortly.The authority also has an agreement with the City of Ballarat to provide treated wastewater from the plant to use on its redevelopment of Austar Arena at Ballarat North Football Club and Ballarat Botanical Gardens.
