Water saving life hacks
In your home
- Turn the tap off while brushing your teeth.
- Take shorter showers.
- Fix any leaky taps, toilets, showers, and dripping garden taps.
- Install dual-flush toilets instead of single flush toilets when renovating.
- Use the dishwasher and washing machine only when you have a full load.
- Put the plug in the sink when shaving or washing hands, dishes or vegetables, and run just enough water for what you’re doing.
- Don’t use your toilet as a rubbish bin; it takes a lot more water to flush down sanitary waste, cigarette butts, food leftovers, etc.
- Install a shower flow-saver disc to your existing shower to not only reduce the excess flow of water but also your water heating bill.
- Use water-efficient appliances, bathroom fittings and tapware.
- The “star” rating stickers indicate the water-efficiency, and there can be large differences in water use between products, so make sure to buy or upgrade to water-efficient when possible.
Outside your home
- Use a hose with a trigger to control the water flow and the start-stop action. It also helps direct water without wasting any.
- Turn the tap off when you’re finished.
- Use a broom to sweep hard surfaces like paths and driveways instead of trying to hose down leaves and twigs.
- Use a bucket and sponge instead of a hose to wash your car and, where possible, wash your car on the lawn to prevent soapy water from entering the street drain and into streams and rivers.
In your garden
- Switch to drought-tolerant plants to cope with dry summer weather and watering restrictions.
- Recycle bath/shower water or water used in your washing machine (also called greywater) on the garden, but only on plants that are not going to be eaten. Greywater should not be stored and should be used immediately to prevent disease.
- Group your plants into high or low water users to develop an efficient watering system.
- Use mulch to retain moisture in the soil and to protect from drying effects of wind and sun. Mulching also helps keep weeds AWAY.
- Weed your garden regularly as weeds compete for available moisture.
- Leaf cover and lawn clippings left on the lawn serve as a good mulch to provide shade, slow water loss, conserve moisture and help preserve nutrients in the soil.
- Test soil moisture every 4-7 days during dry weather conditions, and only water if needed.
- Don’t let the sun and wind strip your plants off their moisture. Water your garden on calm days during the cool hours – early morning or evening – to avoid rapid evaporation.
- Water your garden low and slow – plants take up moisture through their feeder roots and low, slow watering by hand is the best way to get it there. Moveable sprinklers are the least water effective.
- Deep soak your plants to encourage feeder roots to grow deeply in search of water instead of sprinkling, which encourages shallow roots.
- Avoid over-watering your plants as it encourages fungus, root rot, rusts, mildew and black-spot.
