Whanganui District Council provides the city’s residents with a continuous supply of water at acceptable volume, pressure and quality, as well as a fire-fighting capacity in defined areas.
Water used in Whanganui’s urban area comes from four artesian bores – three at Kai Iwi and one at Aramoho.

An auxiliary bore is also available at the Westmere water facility on State Highway 3 – three large reservoirs, each holding 23,000 cubic metres of water, provide the bulk of supply storage. Some auxiliary storage is also available at Bastia Hill and Aramoho.
After treatment, water is supplied to the city and distributed to consumers through the reticulation network using pump stations in certain areas to maintain the desired pressure and flow.
Separate rural schemes are operated at Fordell, Mowhanau, Westmere and Maxwell. Each scheme has its own committee.

Brown tap water
If your tap water is brown, it’s likely that work on the pipes in your area has dislodged some silt from inside of the pipes. Run the COLD tap for 10 minutes to see if it clears. If it doesn't clear, please report it to Whanganui District Council on the 24-hour phone line (06) 349-0001.
Use of sprinklers
There are NO restrictions on the use of automatic garden sprinklers. Hand-held hoses can also be used at any time.
Ministry of Health Public Notice
Some plumbing fittings have the potential to allow minute traces of metals to accumulate in water standing in the fittings for several hours.
Although the health risk is small, the Ministry of Health recommends that you flush a mugful of water from your drinking-water tap each morning before use to remove any metals that may have dissolved from the plumbing fittings.
We are recommending this simple precaution for all households, including those on public and private water supplies.
