Rainwater harvesting, greywater recycling, smart irrigation and pressure-reducing fixtures — we'll cut your water bill and your environmental footprint.
Australian water bills are climbing fast. A typical home can cut water consumption 30–50% with the right fixture upgrades, rainwater harvesting and greywater recycling — paying back the investment in 4–8 years.
We design and install rainwater tanks, greywater treatment systems, smart irrigation controllers, and pressure-reducing/aerating tap and shower fixtures.
Typical savings: 30–50% with the right combination of low-flow fixtures, rainwater harvesting and pressure reduction. Payback on the package is usually 4–8 years through reduced water and waste-water bills.
Yes for laundry, toilets and garden — these uses don't need potable water. A 5,000L tank in a typical Sydney/Melbourne house captures 50–70% of total household water demand. Installation includes pump, controls and integration with your existing plumbing.
Greywater systems treat shower and laundry water for reuse on garden irrigation. They make sense for larger gardens (200m²+) and homes in water-restricted areas. Council compliance certificates included.
"AHHAC delivered our 22-zone underfloor system on time, on budget and to spec. The crew were tidy, the documentation was thorough, and the commissioning was textbook."
"We've worked with AHHAC for 17 years. They've installed and serviced our hot water plant across three commercial buildings — and they pick up the phone on weekends."
"Three mobs quoted us; AHHAC's design was the only one based on a proper heat-loss calculation. The system runs beautifully — the others would've been oversized and expensive."
