The Johnsonville water main
Tiaki Wai is renewing an ageing drinking water pipe, in poor condition, that was laid between 1957 and 1960 along Johnsonville Road, Disraeli Street and Broderick Road. The first phase runs on Broderick Road between Bannister Avenue and Moorefield Road and should take three months; the whole project is planned to take a year. Separately, the pumps at the Johnsonville Pump Station, which move bulk drinking water through the network, are being upgraded for Greater Wellington.
The main is Tiaki Wai's. If your supply cuts out or the pressure changes while crews are nearby, check with Tiaki Wai before calling a plumber.
Johnsonville homes
Many households don't own
In 2023, 39.5% of Johnsonville households neither owned their home nor held it in a family trust, above the 34% national rate. If that's you, involve the owner early: the lateral is theirs to maintain.
Smaller homes
A quarter of the 4,206 occupied homes (25.4%) had two bedrooms, against 19.5% nationally.
Electric and gas heat
Heat pumps (68%) and electric heaters (54.6%) were the main heating. Fixed gas heaters were in 16.1% of homes, so gasfitting work comes up too.
On a major fault
WREMO says Wellington City sits on the Wellington Fault, one of the most active in the plate collision zone, with many more faults nearby.
Pipes that are yours
Tiaki Wai's rule is that the lateral, the pipe linking your home to the public wastewater network, is the property owner's to look after. Blocked or damaged gully traps and private pipes need a plumber. Where exactly its water pipe ends at the boundary isn't published for Wellington City, so ask Tiaki Wai before work near the street.

What we would do
Planning an extension, sleepout or retaining wall? Find out first whether a public pipe crosses your section. Tiaki Wai says works within 3 metres of its network generally need its approval, and it won't approve building over service connections, water supply pipes or sewer pressure pipes. Tiaki Wai has guidance on locating public pipes, a drainlayer can trace private ones, and asking before the plans are final saves a redesign.
