As the rising cost of living in Auckland continues to hit all our wallets, nothing stings like opening a water bill after a month of heavy use. Switching to harvested rainwater can make a real dent in your costs and put clean water to work where it matters most. Here are five simple ways to use rainwater from your tank and start seeing those savings.
Toilet Flushing
Toilets account for nearly a third of household water use. By routing harvested rainwater to your cisterns, you can reduce mains water demand dramatically. Modern pumps and filtration make it safe, hygienic, and reliable.
Laundry and Washing Machines
Rainwater is actually softer than treated tap supply water and it is kinder to delicate fabrics. Connecting your washing machine to a dedicated rainwater line cuts your water bill and improves wash quality in one go.
Garden and Lawn Irrigation
Watering plants can eat up (or drink up) hundreds of litres each week. Using stored roof runoff keeps flower beds and vegetable patches thriving without dipping into treated water reservoirs. Timed drip irrigation systems make every drop count.
Car and Equipment Cleaning
Washing cars, outdoor furniture, or animal pens with rainwater avoids some of the harsh minerals found in mains water. You will see fewer spots on paintwork and pay a fraction of the cost charged by water utilities.
Household Cleaning Tasks
For mopping floors, wiping down surfaces, or pressure cleaning outdoor areas, rainwater is ideal. Your tank becomes a ready-to-use source for heavy-duty cleaning, with zero impact on your water bill.
