Clutha District Council

Contract 883 - Mt Cooee LPS and Owaka WWPS

Clutha District Council is now inviting tenders for the renewal of wastewater upgrades at Mt Cooee and Owaka Sewer Pump Stations.

Mt Cooee:
Installation of a new leachate pumping station at a deeper depth to allow gravity flow from the collection manhole, a reduction in size of the leachate pond, new pipework connection to the existing emergency overflow pond and reconnection to the existing rising main out to the sewer pump station.
There are three ponds at Mt Cooee, two are used for stormwater and one for leachate detention. The two stormwater ponds will be connected to the new irrigation pump manhole and a rising main will be installed for future use.

Owaka:
Installation of new wastewater pump station at a new location, upstream of the existing pump station. The new WWPS will be located at a higher elevation, compared to the existing site, and upgraded with an increased pump flow capacity and emergency storage.
