Kerepehi Water Treatment Plant
Two new drinking water reservoirs
The Council is installing two new 4,015m3 drinking water reservoirs at the Kerepehi Water Treatment Plant. The existing reservoir holds 2000m3, which is not enough to keep Hauraki Plains taps running for long in the event of an unexpected plant shutdown.
The addition of the new tanks will allow the storage 10,000m3 of clean drinking water, which means about 24 hours of supply in the event of a temporary plant shutdown.
The site was pre-loaded with gravel due to the unstable ground conditions of the Plains. The weight of this gravel compresses the site to find out what will happen to the ground when the weight of a structure is added. The gravel was then removed.
The testing revealed a few things that required a redesign to the reservoir foundations. Not so surprising given the nature of building on the Plains but this held up work at the site for a couple of weeks. It also resulted in a slight increase to our overall investment in the project.

Reservoirs nearing completion
Both reservoirs are now nearing completion with the roof on the easterly tank finished and nearly completed on the second tank. Work will then continue on the inside of the reservoirs.
Council's Construction and Maintenance team will install the remainder of the pipe work between the two tanks.
The connection to the water treatment plant will require two water shutdowns. These will be notified to those affected nearer to the date.
Kerepehi Town Road
Surface work to Kerepehi Town Road will be completed in April.
A large trench had been dug across the road while new water pipes were installed.
Dates to be advised.
The new reservoirs are on track to be up and running in April 2019.
