As the summer months bring dry and hot weather, many areas are facing hosepipe bans to conserve water and protect public supplies. However, this can be devastating for gardeners who rely on regular watering to keep their plants healthy and thriving. Fortunately, consumer experts at Which? have discovered a way to get around the ban without breaking any rules. The solution is called 'grey water', which is essentially recycled domestic wastewater that can be used to water plants and lawns.
Grey water is broken down into two types: 'light grey' water, which comes from washing hands or taking a bath or shower, and 'dark grey' water, which is soapy dish water. The easiest way to collect grey water is by using a washing-up bowl in the sink or shower, which catches any runoff water that can be used for watering plants. This method is not only eco-friendly but also perfectly legal, as it does not place extra demand on public water treatment supplies.
It is essential to note that grey water should be used quickly and not stored for too long, as stagnant water can become a breeding ground for bacteria and attract bugs and pests. Additionally, not all grey water is safe to reuse, and some types should be avoided altogether. For example, water with a softener in it, especially sodium-based, can damage soil structure and harm plants and the ecosystem. Water mixed with strong cleaning chemicals like bleach or petroleum-based products should also be avoided, as they can harm plants and contaminate the soil.
While flower and grass lawns can benefit from recycled grey water, gardeners who grow fruit or vegetable patches should exercise caution due to the risk of contamination. To minimize this risk, it is recommended to alternate between grey water and tap water, allowing any salts or contaminants added to the soil to be washed through and preventing buildup. This is particularly important for plants in pots and baskets, which contain relatively small amounts of compost.
Hosepipe bans, also known as Temporary Use Bans, are enforced by water companies to protect public water supplies, safeguard essential needs like drinking and sanitation, and prevent environmental damage to low rivers and reservoirs during dry weather and heatwaves. The bans can carry a fine of up to £1,000 for homes that break the rules, and water company staff monitor compliance, with members of the public able to report suspected rulebreakers directly to their regional water provider.
By using grey water, gardeners can keep their plants healthy and thriving while also doing their part to conserve water and protect the environment. As the summer months continue to bring dry and hot weather, it is essential to explore alternative methods of watering plants and lawns. With a little creativity and resourcefulness, gardeners can beat the hosepipe ban and enjoy a lush and vibrant garden all season long.
