Why Reducing Hot Water Usage Can Cut Your Utility Bill

In New Zealand, the right sewage system at home can also spell the difference for your water consumption. It’s better to choose a natural treatment system to avoid paying the extra cost for electricity and even help the environment further.

Hot Water Use

The Energy Efficiency and Conservation Authority reminded households to turn off the faucet when washing dishes or taking a hot shower while soaping. If you have a dishwasher, you can use more it efficiently by only turning it on with a full load. This ensures that the machine maximises the use of hot water.

Those who can’t simply reduce their consumption of heated water should consider upgrading their system. Some newer models are preset to certain temperatures. They not only prevent people from burning themselves but also set a predetermined energy usage. Another way to reduce your reliance on hot water involves reusing grey water around the house.

Recycling Used Water

Grey water is defined as waste water coming from washing machines, showers, kitchen and bathroom sinks. You should find out if your area requires a permit for reusing grey water. Take note that grey water can be used for watering plants and flushing the toilet, although kitchen grey water should probably go straight to your sewage system.

If you solely plan to use for watering the garden, the installation should be structured in a way that distributes grey water below the ground. Don’t use it for food plants and other types of crops for household consumption.


It’s easier said than done when planning to reduce hot water use, especially if you live in colder climates in New Zealand. However, there are now more options for households to reduce their consumption and save their wallets from expensive utility bills.
