Wellington Water was established in September 2014 as a result of a merger between Capacity Infrastructure Services and Greater Wellington Regional Councils water supply group.

We are owned by the Hutt, Porirua, Upper Hutt and Wellington city councils, South Wairarapa District Council and Greater Wellington Regional Council. The councils are all equal shareholders.

Our role is to manage the drinking water, wastewater and stormwater services of our council owners.

Capacity Infrastructure Services

Capacity was established in 2004 as a shared service council controlled trading organisation, jointly owned by the Hutt and Wellington city councils. Its focus was to provide high quality, safe and environmentally sustainable services to its shareholders with a focus on asset management planning and contracted service delivery. In 2008 Upper Hutt City Council contracted Capacity to manage its water, stormwater and wastewater services and assets.

Capacity achieved ISO 9001:2000 certification in November 2008.

On November 1, 2013, Capacity's ownership was restructured with Hutt, Porirua, Upper Hutt and Wellington city councils all becoming equal shareholders.
