Hastings residents are being asked to conserve water while bores are tested.
Bores will be checked by Hastings District Council this month to determine their capacity to meet future water needs. Information will be used to support a new resource consent application to take water from the aquifer supplying Hastings, Havelock North and Flaxmere.
Residents may experience slightly lower or fluctuating pressures during the testing, and are asked to reduce water use to ensure supply can be maintained.
"Some slight discoloration of the water may be noticeable while the testing takes place but it will be safe to drink at all times," Water Supply Manager Dylan Stuijt said.
If the discoloration doesn't clear after running a tap for a few minutes, people should contact the council.
Testing began yesterday at the Lyndhurst bore at Frimley Park, followed by the Wilson Rd bore from May 16, the Portsmouth Rd bores from May 23rd, and the Eastbourne bores on May 30.
