Upper Hutt grew quickly after the war on farmland around the town centre, with early subdivisions such as the Buckleton Estate in 1947, the Coltman Estate in Ebdentown in 1949, Windsor Park Estate in Clouston Park in 1950 and the Cottle Block in Trentham in 1955. Tōtara Park, Timberlea, Parkdale and Kingsley Heights followed in the 1960s and 1970s, and subdivision in areas such as Maoribank and Kingsley Heights continued into the 1980s. We handle all of it: placement and sizing, connecting to spouting and downpipes, pressure pumps, first-flush diverters, filtration and UV, and any mains top-up with the backflow protection it needs.
Rainwater tanks in Upper Hutt: year-round Level 1 and the valley's heavier rain
Upper Hutt is the part of the region where watering rules never fully switch off. Tiaki Wai's Level 1 restrictions apply all year round there, which means sprinklers and irrigation on alternate days only, by house number, between 6 and 8am and 7 and 9pm. For keen gardeners and anyone with a large section, a rainwater tank is the simplest way to water more freely, because the water comes off your own roof rather than the public network. We can fit a pump and garden taps so the tank is as easy to use as the mains.
The valley gets plenty of rain to fill a tank. Wallaceville, in Upper Hutt, averages about 1,268 mm a year, noticeably wetter than Wellington Airport, and winter is the wettest season. A tank sized to the roof and to summer garden use will usually refill well between dry spells, and a larger tank carries you through a longer one. The town's own supply comes from the Te Mārua treatment plant, which takes Hutt River water at the Kaitoke Weir and keeps the Macaskill storage lakes as a backup. Tank water is not treated like that supply, so if you want to drink it, we can add filtration and UV.
Upper Hutt's housing suits tanks well. Post-war estates in Trentham, Ebdentown and Clouston Park have reasonable sections, and lifestyle blocks at the city edge often have sheds and outbuildings with large roofs ideal for collection. We set tanks on firm, level bases on the gravelly valley floor, fit leaf screens and first-flush diverters, and run overflows to stormwater, which in Upper Hutt is always the owner's responsibility right down to the point of discharge. If the tank is plumbed into the house with mains top-up, we add backflow protection.
Local tip: Collect from a shed or garage roof as well as the house in Upper Hutt, because extra roof area keeps a garden tank full through the year-round Level 1 rules.

Water Tanks Upper Hutt FAQs
Do Upper Hutt water restrictions stop me watering from my tank?
Restrictions apply to water from the public network. A tank gives you a separate supply for the garden; if you are unsure how the rules apply to your setup, check with Tiaki Wai.
Can a tank supply my toilets and washing machine?
Yes. That needs a pump and usually a building consent, and the plumbing must be done by a licensed plumber.
Do I need consent for a rainwater tank in Wellington?
Not always. Some outdoor-use tanks sitting on the ground are exempt under national guidance, but tanks feeding internal plumbing or with a mains top-up usually need consent. Check with your council, or we will check for you.
