A town of about 28,800 people with older town housing and new subdivisions, surrounded by market gardens, farms and lifestyle properties. We handle both. That includes tank placement and sizing, connecting to spouting and downpipes, pressure pumps, first-flush diverters, filtration and UV, and any mains top-up or backflow protection the setup needs.
Pukekohe rainwater tanks: when the tank is the household's whole supply
Pukekohe town is supplied by Watercare from deep bores, about 270 metres underground, with iron and manganese filtered out at the treatment plant. Out past the town boundary it is a different story. Rural properties among the market gardens, farms and lifestyle blocks commonly rely on rainwater tanks for every drop they use, which Auckland Council describes as typical for rural Auckland. On those properties the tank is not a garden extra. It is the drinking water.
That changes how a tank system is designed. We size for summer, when rainfall drops and garden and stock use climb, and look at roof area, number of people and how long the household needs to last between good rains. Where one tank is not enough, a second tank or a plan for water carrier top-ups may be needed. Pumps need to be reliable, with a pressure tank to reduce cycling, because a failed pump means no water at all.
Rural roofs collect more than rain. Pukekohe's cultivated land, worked for generations as Auckland's and Wellington's vegetable garden, means dust can settle on roofs during dry, windy spells, along with leaves, bird droppings and pollen. A first-flush diverter, leaf guards, a calmed inlet and a floating intake keep most of that out of the drinking supply, followed by a sediment cartridge, a carbon stage and a UV lamp downstream of the pump. We also check that the roof and spouting materials are suitable for collecting drinking water.
Pukekohe sits on the older South Auckland volcanic field, and the weathered volcanic soils give a reasonable tank base on most sites, though large tanks still need a level, compacted pad. Inside town, tanks are usually for gardens and toilets, with consent and backflow checked where they connect to internal plumbing.
Local tip: On a rural Pukekohe block, rinse dust off the roof and clear the first-flush chamber after a long dry spell before the first big rain refills the tank.

Water Tanks Pukekohe FAQs
Our Pukekohe lifestyle block has no town water. How big should our rainwater tank be?
It depends on roof area, household size and how long you need to last through summer. We size for the dry months and look at whether a second tank or water carrier top-ups make sense.
Can I drink rainwater from my tank?
It can be made safe with good roof and tank maintenance, a first-flush diverter, filtration and UV treatment.
Do I need backflow protection if my tank has a mains top-up?
Yes. Any connection between a tank and the mains needs the right backflow protection to protect the public supply.
