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 and 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.
- Assessing earthquake resilience – We will continue to assess the ability of our water, stormwater, and wastewater services to cope with an earthquake. We will carry out risk assessments to identify network weaknesses and then to plan for appropriate remedial programmes. Such assessments include checking the current seismic strength of water reservoirs, pump stations, telemetry systems and critical pipeline fittings/fixtures.
- Strengthening Karori Dam – We look after the Karori Dam in Zealandia. In 2013/14 we will undertake regular safety inspections and valve strengthening on the dam.
- Emergency preparedness – 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. These valves are triggered through the sudden loss of stored water following an earthquake. This work will continue in 2013/14 with seismic coupling installation and emergency water tank installation.
- New standards for fire fighting – We will continue upgrading parts of the water network to meet new standards for fire fighting.
- Regional water services – Wellington City Council and Hutt City Council have approved requests from Porirua City Council and Upper Hutt City Council to become shareholders in Capacity Infrastructure Services Ltd, our existing three-waters service management company. All shareholder customers will aim to move to a common outcomes-based business model. Under this model each Council will retain ownership of its water assets and opportunities for efficiency gains in the longer term will be investigated. We are now going through the process to commence implementation in 2013/14.
Measuring our performanceTop
Our targets for 2013/14 are:
- All water delivered to Wellington properties complies with Drinking Water Standards for New Zealand (2005).
- 90% of residents agree that water services provide good value for money
- The number of complaints regarding water quality (taste and odour) is less than 200.
- 95% of customers are satisfied with water quality and network service
- 97% of properties receive appropriate water pressure (a minimum of 250kPa)
- 95% of fire hydrants tested meet New Zealand Fire Service Code of Practice for fire fighting water supply requirements.
- The water distribution network receives an ’a’ to ’b’ grading from the Ministry of Health (‘a’ = completely satisfactory, very low level of risk, and ‘b’ = satisfactory, very low level of risk).
- 97% of service requests relating to the water network are responded to within one hour of notification.
- No more than 14% of water in the network is unaccounted for
- Residential water consumption per person per day is 290 litres (residential water consumption is based on bulk water supplied less the metered commercial consumption divided by resident population).
- Total water consumption during the year will be less than 30 billion litres
