Ellora Street (Ngaio), water main renewal

Work to renew the water main in Ellora Street began on 10 May 2016 and will be completed by mid-June.

The contractor is Construction Contracts Ltd (Paul Jackson, 021 546 017).

The Esplanade (Petone)

We're installing new pipework either side of the Korokoro valve chamber (located opposite 47 The Esplanade) from Monday 4 April 2016. For more information, check out this project page.

Churchill Drive (Crofton Downs), water main renewal

Work to renew the water main in Churchill Drive began on Tuesday 29 March 2016 and will be completed in mid to late June.

Renewing the water main is important because the existing pipework is getting to the end of its life. The upgrade will help to provide a more reliable and resilient water supply network in Wellington city. Find out more about this work here.

Molesworth Street (Thorndon), stormwater and wastewater renewal

Work to renew the stormwater and wastewater pipes buried beneath Molesworth Street is scheduled to be completed before the end of September 2016.

The work involves replacing pipes from Little Pipitea Street to just past the motorway on-ramp (87 – 133 Molesworth Street).  Read more about this job here.

New Melrose reservoir bigger, stronger, safer

Work is nearing completion on a new reservoir in Mt Albert Park – part of an ongoing programme to make the Capital’s water storage facilities and supply network stronger, safer and better able to meet the needs of a growing population.

The new reservoir, being managed by Wellington Water on behalf of Wellington City Council, will provide three times more water storage for the Melrose area.

Melrose reservoir

Reservoir, what reservoir? Burying the reservoir is almost complete

Wellington City Council has done a lot of work over the past 20 years to earthquake-strengthen existing reservoirs, build new ones to stringent seismic standards and install automatic shut-off valves so the tanks don’t empty if the pipe network is damaged.

About 66 percent of the water in the city is now stored in reservoirs that have been seismically strengthened and more than 95 percent have shut-off valves.

The new Mt Albert Park reservoir will be more resilient during a severe earthquake and also allow for population growth over the next 80 years.  It will replace the older of the park’s two reservoirs, which was built in 1910.

Catchment management planning

We're working on a long term plan to improve the management of stormwater in Wellington City. Stage one of the plan looked at the characteristics of Wellington's 34 sub-catchments. In Stage Two, we'll develop action plans for five groups of catchments.

More information and the Stage one report is available. You can also read the Annual Report on the stormwater discharge consents, showing the performance of Wellington City's stormwater catchments.
