Demolition of Old Reservoirs

26 November 2013

We’ve been progressively upgrading the city’s reservoirs and developing some strong new ones and are now demolishing a few that are no longer required.

Capacity Infrastructure Services, the council-owned water services management company, has started removing tanks in Northland and Khandallah, and will be demolishing others in Karori, Seatoun, Woodridge and Mt Cook soon.

Project manager Sarath Amaresekera says the tanks are no longer needed as a result of work programmes over the past few years to improve the resilience of the city’s water supply network.

“Some of the tanks being removed are nearly 100 years old and most are quite small,” he says. “It’s safer to pull them down than leave them in place.”

Extensive work has been going on over the past 20 years to earthquake strengthen reservoirs or build new ones to stringent seismic standards. The biggest project in recent years was the $6 million redevelopment of the reservoir in Messines Road in Karori. It involved the demolition of two old tanks and construction of new ones with twice the capacity.
