High winds damaged one of two new reservoirs being built for the upgrade to Methven’s water supply last week.

Methven’s water supply upgrade suffered an estimated two-month delay due to damage from recent high winds.

As wild weather last week forced another precautionary boil water advisory in Methven, one of two new reservoirs being built was badly damaged. The tanks are part of a $9.4 million project that will end the need for parking tankers in town.

Ashburton District Council’s Infrastructure Services Group manager, Neil McCann, said the damage would cause the project to be delayed by two months as spares had to be imported from the UK.

“The other tank was fortunately untouched as the roof had already been fitted.”

“The contractors did what they could, but with winds of over 150 km/h on the exposed site, there was not much to do in the circumstances.

“Methven’s water supply will not be affected as we continue to use the existing concrete reservoir.”

The costs of damage and delay were covered by the contractor‘s insurance, McCann said.

Construction of the new reservoirs is the first stage of upgrading Methven’s water supply, and the next stage involves the construction of a new membrane treatment plant which will provide effective treatment even in the event of flooding. – and the end of boil water advisories.

The other of Methven's two water tanks was undamaged as its roof had already been installed.

“As soon as the other tank is completed and commissioned, it will come online to complement the existing storage tank.”

“Work on the other stage involving the membrane processing plant will not be affected.”

When the new tanks, with a combined capacity of 1,128 cubic meters, are finally complete, the old concrete tank will be drained to allow a full structural inspection to determine its future viability.

Construction of the membrane plant is expected to begin later this year and could take nine months.
