The Council’s $6 million investment in a pump station to reduce the flooding risk in the Flockton area is already paying dividends.
The new Tay Street pump station was activated at the weekend as Christchurch was hit by 24 millimetres of rain in nine hours.
At the height of its operation the pump station was removing about two tonnes of water a second from the Flockton area.
“It was the first true test of the pump station and it certainly proved its worth as we had no major flooding issues. It was only a fairly typical winter storm event we were dealing with but everything worked as it should,’’ said Land Drainage Manager Keith Davison.
The Tay St pump station was installed by the Council last year as part of a raft of measures to reduce the flood risk in the Flockton area, which has become more susceptible to flooding since the earthquakes.
A bypass to divert water away from Dudley Creek is currently under construction as part of a $48 million flood mitigation scheme for the area that is due to be completed by winter next year.
“When work on the main scheme is completed by this time next year the flood risk should be back to pre-quake levels,’’ Mr Davison said.
Activating the Tay Street pump station was one of many precautions the Council took in response to the heavy rain forecast last weekend.
City Care was out clearing grates, checks were made on outlets and other pumps, and temporary pumps where on standby.
