Using tap water for outdoor tasks like washing the car, watering plants or filling paddling pools in the garden accounts for around 7 per cent of total household use in a year and this can be much higher in dry weather. In fact, on a hot summer’s day we can put up to an extra 80 million litres of water into supply.
Water saving tips
Smarter watering:
- Lawns do not need to be watered as grass is drought-resistant - as soon as the rain returns it will go from brown to green! New turf only needs watering for the first month
- Only water seedlings and young plants regularly mature plants can usually go five days or more without a top-up
- Encourage deep, strong roots by watering less often but more thoroughly
- Use a watering can filled from your water butt, remove the rosehead and aim directly at the base of the plant - watering the surrounding soil only feeds weeds
- Collect rain water in water butts – plants prefer untreated water
- Use water storage gels or granules in pot plants and hanging baskets which means you can water them less often
- You could also consider planting drought-resistant plants and flowers which can better withstand long dry spells and require minimal water to survive
- Water early in the morning or late in the evening to reduce evaporation and make every drop count.
Be water-wise when washing your car:
- Try waterless car wash products for quick, eco-friendly cleaning
- Use a bucket and sponge instead of a hose to cut water use
- Fill your bucket from a water butt - plants love it, and so will your car
- Spot clean between full washes to avoid using water unnecessarily
- Wash early or late in the day to reduce evaporation.
