Water supply unaffected by spill

Sep 14, 2009

A sewage spill at Kelvin Heights yesterday had no impact on water supply and was quickly dispersed, Queenstown Lakes District Council water services manager Garry McGraw said.

A blockage in a sewerage main caused a manhole to overflow, sending approximately 1000 litres of wastewater into the lake, below Peninsula Road at around 12.30pm.

“With any spill in the Frankton Arm area, the council must act in an entirely precautionary way, due to the Kelvin Heights water supply intake,” Mr McGraw said.

Although the intake is situated deep in the lake, contractors were quick to close off the intake and isolate the supply, on detection of the spill.

“As usual we are grateful to members of the public for alerting the council quickly and allowing our contractors to ensure there was no major incident,” Mr McGraw said.

The main was found to be blocked with material.

“There are limits as to what can be safely disposed of, certainly we would ask that nobody places any inappropriate material in the system, otherwise people are placing the environment at risk,” Mr McGraw said.

The spill was quickly dispersed yesterday; the area sanitised and water samples taken.

“The results today show that the water is clear of any contamination and again we have taken a further set of tests today as a precaution,” Mr McGraw said.
