The Council provides a water supply system for the supply of potable water as well as for fire-fighting purposes. Water is drawn from the Heretaunga Plains artesian aquifer and reticulated to the Napier urban area and to Bay View. While the Heretaunga Plains aquifer is the source of high quality water, NCC adopted Ministry of Health and Hawke’s Bay District Health Board’s recommendations to continue with chlorination of our water supply.
The Napier water supply system consists of 481km of mains, nine reservoirs and 18 pump stations. Each month 27 residential zones, nine bores and all eight reservoirs are sampled and tested by an IANZ-accredited laboratory to ensure your drinking water is safe.
A total of 9.5 million cubic metres of water was distributed for the year ending 30 June 2017.
Napier City is primarily urban with 93% of the citizens living within the urban area. Water is reticulated to the Napier and Bay View urban areas. A small number of rural properties adjacent to the urban reticulation system are connected to this supply for domestic use.
The remainder of the rural area is not forgotten. Council considers all water supply proposals from rural residents, providing assistance and, where appropriate, funding.
Council runs a water conservation programme during the summer months to raise awareness and promote the efficient use of water.
Napier's water journey from aquifer to tap
We draw our town water supply from an aquifer deep underground. This water may be high quality, but before we can drink it, we need to transport the water up through bores, into our reservoirs, and through our pipe network to the taps in our homes and businesses.
This pathway from aquifer to tap is where the risk factors of contamination lie — in the 9 bores, the 11 reservoirs on seven
different sites, and the 481km of pipes that transport water around Napier. At each stage we need multiple barriers in place to deliver safe drinking water.
We’ve learned a lot about our aquifer in the last year. In some bores the water is just two years old. So the old thinking that water was 40 to 70 years old is no longer valid. We also know there are seasonal variations in water age, and we're continually carrying out testing to further understand such trends. Take a look at the diagram below to learn more about how you get the water to your home.
