Sewer under pressure

The Lake Hawea sewer is under pressure and likely to overflow during high rainfalls, so the Queenstown Lakes District Council is keen to talk to property owners next month about ways to reduce the problem.

Early next month, council engineers Martin Ellis and Mark Gendell will contact those Lake Hawea property owners where better storm water solutions could be introduced.

The measures should be relatively simple and cost $150-$600, 3 Waters manager Gerry Essenberg said in an update to the Lake Hawea Community Association this week.

The most common problem is with gulley traps being lower than ground level, which allows storm water to drain into foul water drainage on the property and then the sewer, resulting in an overload at the sewage treatment facilities.

Some storm water down pipes and other drains are also discharging into the foul drainage system.

The association will meet on January 9 at the Lake Hawea Community Centre at 10am to discuss the sewers, storm water solutions and the council's draft management plan for the lake shore.

The meeting is open to the public.
