Practical Australian actions

Use less, fix leaks, then talk about tanks

Australian household water efficiency starts with WELS-rated fittings and visible leaks. Rainwater and greywater are legal questions as much as plumbing questions.

Home / Water

Water advice that skips the label and the leak is just a slogan. Your Home and the Water Rating scheme already give Australian households a way to compare fittings and to see why a dripping tap defeats a motivational sticker. This hub keeps that order and refuses to invent a household bill saving for your town.

Answer first

If water is the problem you can see, fix the leak and read the WELS label on the next tap, shower, toilet or washer you buy. If the garden is the problem, water in the cool part of the day, mulch, and choose plants that match the rainfall you actually get — then read the gardens hub. If you are considering rainwater or greywater, stop at the planning and plumbing question before you stop at the tank colour.

Indoor water is mostly fittings and time

Your Home is blunt about showers, taps and toilets because that is where indoor water usually goes. An inefficient shower can run in the teens to twenties of litres per minute; a high-WELS rose is much lower. Those ranges are Your Home’s, not ours. The label also shows the flow figure, which is the number to compare when two products have similar stars.

Mixer taps reduce the circus of waiting for a temperature. Dual-flush toilets should be used as dual-flush toilets. Dishwashers and clothes washers belong on the WELS and Energy Rating labels together, because the efficient cycle is both a water and an energy setting. Your Home’s habit list — full loads, eco cycles, scraping rather than rinsing — does not need a new brand name.

We will not reprint a national “save $X” line as if it were your bill. Your Home discusses scheme-level household framing on the WELS page. Use that page if you want the official wording. Use your water utility’s own calculator if they publish one.

Leaks are not a personality flaw

A washer, a cistern inlet, an irrigation solenoid and a forgotten hose bibb can each waste more than a shorter shower. Put a mark on the water meter (where you have one) and wait with no fittings in use. If the meter still climbs, you have a leak hunt, not a lifestyle lecture. Underground leaks need a licensed plumber. Garden drips often need a tap reseat you can see.

Hot leaks are energy leaks. That is why this hub and the energy hub keep linking to each other.

Outdoor water is design, not willpower

A lawn that only exists because the sprinkler exists is a design problem. The gardens hub covers soil, mulch, natives and hydrozoning. This page only needs one sentence: irrigation without a controller, a season, and a plant list is a leak with a timer.

Some utilities publish outdoor watering rules during restrictions. Those rules are local and change. We will not freeze them here.

Rainwater is a site, not a personality

A tank can offset toilet, laundry or garden demand where the roof, the first-flush, the overflow and the plumbing isolation are done properly. It can also sit unused because nobody plumbed a toilet or because strata said no. State health departments and plumbing standards govern potable versus non-potable uses. Your Home discusses rainwater as part of a household water strategy; your certifier and plumber apply it. Bushfire, mosquito and structural-pad questions are real. This site will not size your tank.

Greywater is a health document

Laundry-to-landscape hoses, diversions from showers, and fully treated systems are not the same product. Untreated greywater can carry pathogens, salts and boron from detergents. Several states restrict untreated greywater to certain subsurface uses and ban it on food plants or after storage. Treat that as a regulator conversation. If a page on this site ever sounds like a plumbing diagram, ignore it and call a licensed plumber.

Utilities, data and courtesy

The Bureau of Meteorology publishes water information for catchments and storages. That is context, not a household target. Your retailer or council may have a rebate for fittings. Those dollar figures change. We will not copy them. If you want help finding the right official page, use contact.

Water efficiency is one of the few household actions that still feels like a civic habit in Australian summers. Keep it civic: cite WELS, fix the washer, and do not pour a mystery pipe into the veggie bed.

Apartments and central hot water

Many apartments cannot choose a tank and cannot read a unique meter. They can still choose WELS fittings the owner will accept, report cistern leaks, and stop running the shower while they hunt for a towel. Strata reports that name a leaking common riser are water policy.

Central hot water makes a dripping shower an energy complaint for the whole building. Say so in the email to the manager and attach Your Home.

The indoor water guide and the reuse guide split the detail so this hub can stay the order: leak, label, then law.

Questions people ask first

How do I use less water at home in Australia?

Fix leaks, choose higher-WELS taps, showers, toilets and appliances, and change the habits Your Home lists — shorter showers, full loads, and no unnecessary rinsing. Check tank and greywater rules locally.

What is a WELS star rating?

The Water Efficiency Labelling and Standards scheme rates certain products sold in Australia. More stars mean a more efficient product. The label also shows litres per minute or per use. See waterrating.gov.au.

Can I water the garden with greywater?

Sometimes, depending on the system, the state or territory, and whether the work is licensed. Untreated greywater has health and soil limits. Ask the local plumbing regulator and health authority before installing anything.
