How to Save Water at Home: Practical Tips
Cut your water use (and your bills) with simple changes in the bathroom, kitchen, laundry, and garden - no expensive equipment required.
Why Saving Water Matters
Clean fresh water is a limited resource, and treating and pumping it uses significant energy. Using less saves money on water and heating bills, eases pressure on local supplies, and shrinks your environmental footprint. The good news: most households can cut water use substantially with simple, free or low-cost changes.
In the Bathroom
The bathroom is where most household water is used, so it offers the biggest savings.
- Shorten showers: Cutting two minutes saves many litres each time. A timer or a favourite song helps.
- Fit a low-flow showerhead and tap aerators: Cheap to install and they cut flow without you noticing.
- Turn off the tap while brushing teeth or shaving.
- Fix leaks promptly: A dripping tap or running toilet can waste thousands of litres a year.
- Displace toilet volume: A filled bottle in an older cistern reduces water per flush.
In the Kitchen & Laundry
- Run full loads only: Dishwashers and washing machines use about the same water whether full or half-full.
- Don't rinse under a running tap: Use a bowl of water for washing produce and dishes.
- Catch the cold: Collect the water that runs while waiting for it to heat, and use it for plants.
- Keep drinking water in the fridge instead of running the tap until it's cold.
- Wash clothes less often and on cooler, efficient cycles - better for clothes and water alike.
In the Garden
- Water early or late: Watering in the cool of the day reduces evaporation loss.
- Mulch beds: A layer of mulch keeps soil moist and cuts watering needs dramatically.
- Harvest rainwater: A simple barrel off a downpipe gives free water for the garden.
- Choose suitable plants: Native and drought-tolerant species need far less water.
- Reuse greywater: Safe household water (e.g. from rinsing produce) can water non-edible plants.

Frequently Asked Questions
What uses the most water at home?
For most households the bathroom - showers, baths, and toilets - is the largest use, followed by laundry. That's where saving efforts pay off most.
Do low-flow showerheads really work?
Yes. Modern low-flow heads maintain good pressure while using noticeably less water, cutting both water and water-heating energy with no real loss of comfort.
How much water does a dripping tap waste?
A steady drip can waste thousands of litres a year. Fixing leaks is one of the cheapest, highest-impact water savings available.
Is collecting rainwater worth it?
For garden use, yes - a simple barrel captures free water during rain and reduces demand on mains supply during dry spells.
