Irrigation Systems West Auckland

Post-war suburbs from the 1950s and 1960s across Henderson, Glen Eden and Te Atatū, bush homes in the Waitākere foothills, rural blocks around Kumeū, and new townhouses and apartments at New Lynn and Te Atatū. A good irrigation system puts the right amount of water at the roots, at the right time of day, without anyone standing there with a hose. A poor one sprays the fence, floods one bed and leaves the next to die, and in the worst case lets fertiliser-laced water siphon back into the drinking supply.

West Auckland irrigation: tank-fed gardens, steep sections and harbour clays

West Auckland is one of the places where irrigation often runs from a tank rather than the mains. Bush homes in the Waitākere foothills and rural blocks out toward Kumeū frequently rely on rainwater, and every litre used on the garden comes out of the household supply. Watering from a tank calls for a pump matched to the busiest zone, a filter to keep sediment from blocking the drippers, and a sensible schedule so the garden does not drain the tank in a dry month. Drip line under mulch uses far less water than sprays and suits these properties best.

Steep sections are common in the foothills, where the ground is the eroded remains of the ancient Waitākere volcano. If the tank sits below the garden, the pump has to lift water uphill, and the height matters as much as the distance when sizing it. Lifestyle blocks around Kumeū often have long runs from the tank to the garden, so pipe sizes are chosen to limit pressure loss over the distance. Pressure-compensating drippers keep the output even down a slope, and the overflow and any drainage from the system need to stay clear of unstable banks.

In the suburbs of Henderson, Glen Eden and Te Atatū, gardens are on the town supply and the ground is usually clay over sandstone. Short cycles with soak time between suit clay. Near the harbour edges at New Lynn, Te Atatū and Hobsonville, the ground turns to rhyolitic clays and peat that hold water longer, so those zones need lighter schedules.

On the suburban side, a mains-fed garden system needs a double-check valve where it leaves the house supply, and that device is tested once a year. If a tank system has a mains top-up or changeover, the backflow device still belongs on it, so tank water can never be drawn back into the public supply during a pressure drop.

Local tip: If your West Auckland garden runs on tank water, set the irrigation to drip and check the tank level weekly through summer so the house supply is never at risk.
