Thames Water has implemented a temporary usage ban affecting 10.1 million customers, citing high water demand exacerbated by recent heatwaves and prolonged dry weather conditions.
The restrictions prohibit the use of hosepipes for various activities, including watering gardens, washing vehicles, filling ornamental ponds, paddling pools, or swimming pools, and cleaning windows. The use of sprinkler systems is also restricted.
However, certain exemptions are in place. These include needs related to health and safety, animal welfare (encompassing pets, livestock, and fish), watering food crops and newly planted trees. Customers with severe mobility issues, disabilities, or medical conditions that prevent them from adjusting their water use are also exempt, as are wastewater-only customers and Blue Badge holders.
In response to hot weather and potential restrictions, the Royal Horticultural Society (RHS) has advised gardeners to utilize stored rainwater or grey water. They recommend watering plants deeply but infrequently, directing water to the base of the plants rather than frequent, light watering.
"As our climate continues to change, adapting how we manage water is essential," said Guy Barter, chief horticulturalist at the RHS. He noted that observing which plants thrive in current conditions at RHS Gardens and seeking advice from their teams can provide support.
Longer-term strategies for gardens to become more resilient to dry conditions include planting more drought-tolerant species, improving soil health, and increasing tree cover to provide shade.
