Clean, safe water is essential for residents’ quality of life and wellbeing.
What we do
- Water network
- Water collection and treatment.
We ensure Wellingtonians have high-quality water available at all times for drinking as well as other household and business uses. We are responsible for looking after the network, all new connections and making sure all statutory requirements and environmental standards are met. In November 2013 Upper Hutt and Porirua City Councils joined Wellington and Hutt City Councils as shareholders of Capacity Infrastructure Services Ltd. This means the water services for all four councils is managed by Capacity - providing the opportunity to share knowledge and ideas to provide regional solutions for water management.
- We will continue to assess the ability of our water, stormwater, and wastewater services to cope with an earthquake. Such assessments include checking the seismic strength of water reservoirs, pump stations, telemetry systems and critical pipeline fittings/fixtures. Investigations are ongoing and physical strengthening work is underway on the Maldive, Maupuia and Linden reservoirs.
- We have a programme of activities to improve the water network’s resilience and our emergency preparedness. The programme involves a range of projects including the installation of mobile water tanks at key locations and completing the installation of auto shut-off valves on reservoirs.
- We will continue upgrading parts of the water network to meet new standards for fire fighting.
- We will continue to contribute to the Porirua Harbour and Catchment Strategy with Porirua City Council and Greater Wellington Regional Council including sediment reduction plans and community education.
