Council closes Perseverance Dam to the Public

Perseverance Dam

Toowoomba Regional Council has closed Perseverance Dam to the public until further notice as a precautionary move due to elevated numbers of E.Coli bacteria.

Toowoomba Regional Council Water and Waste portfolio leader Cr Bill Cahill said Council officers were satisfied that the increased bacterial numbers were due to an environmental phenomenon rather than contamination of the dam water.

“Council will erect signage indicating the areas are closed to the public until further notice. Council are also notifying relevant stakeholders in the area of the closure.

“Reticulated water within the Perseverance Dam Park is sourced from the Cressbrook Dam and so is unaffected by the closure.

“The bacteria represent no risk to drinking water supplies as they are removed by the water treatment and disinfection process.

“Council monitors the three dams on a weekly basis for algae and numerous microbiological parameters including E.coli. We also test chemical parameters such as iron, manganese, alkalinity, hardness, ammonia, nitrate, colour, turbidity and phosphate.

“When a weekly test returns a result below the minimum recognised safety level for E.Coli council will increase its testing to daily.

“Daily monitoring will ensure affected areas can be re-opened as soon as possible after the first acceptable test result is returned,” Cr Cahill said.

“Council will undertake daily monitoring of these levels and will re-open affected areas as soon as measured levels are below the recognised safety standards,” Cr Cahill said.

“The treatment process is also closely monitored (daily). When the water leaves the treatment plant we conduct tests in the distribution system in accordance with our Drinking Water Quality Management Plans.

“These plans line up with the Water Supply (Safety and Reliability) Act 2008.

“Even if we are not using a particular dam, but a test shows that levels are too high for primary contact (swimming) or secondary contact (boating) we inform Council’s Parks and Recreation Services branch about closing a facility to the public.”

Cressbrook Dam is currently unaffected by this issue and therefore remains open for recreational based activities and camping.
