Water shortages are becoming more common in many areas, and heating water is a significant part of home energy use.

The biggest savings often come from things you cannot see — leaks and inefficient watering.

Find leaks

A dripping tap or a toilet that runs continuously can waste large amounts of water. To check a toilet, add a few drops of food colouring to the cistern; if colour appears in the bowl without flushing, it is leaking.

In the bathroom

Efficient shower heads and dual-flush toilets reduce water use without changing your routine. Turning off the tap while brushing your teeth is a simple habit with real impact.

In the kitchen

Run the dishwasher only when full — it usually uses less water than washing by hand. Keep a jug of tap water in the fridge rather than running the tap until it is cold.

In the garden

Collect rainwater in a water butt
Water early in the morning or in the evening to reduce evaporation
Water deeply and less often to encourage deep roots
Mulch beds to keep moisture in
Choose drought-tolerant plants

Reuse grey water carefully

Bath and washing-up water can be used on ornamental plants if it does not contain harsh chemicals. Do not use it on edible crops, and check any local regulations on grey-water systems.

This is general sustainability information. Recycling, composting, and disposal rules vary by municipality — check local guidance. Cost and energy savings are estimates and depend on your home and usage.
