A blocked sewer pipe led to about 5000 litres of wastewater
ending up in Lake Wakatipu via a drain into Horne Creek early
The Queenstown Lakes District Council was investigating the
cause of the blocked pipe yesterday but said contractors had
reported it appeared to be gravel and stone.
Following the discovery, the blockage was removed, the
foreshore where Horne Creek meets the lake disinfected and
the water tested.
As a precaution, a small area of beach around the creek
outlet was closed yesterday, the council infrastructure and
assets general manager Erik Barnes said.
Because of the blocked pipe, pressure had forced the liquid
up through a manhole.
The council said it was too soon to say what had caused the
overflow, but contractors who cleared the blockage said that
there appeared to be gravel and stone, possibly from
construction debris, in the pipe.
