Thousands of people who live in east Wiltshire, Swindon and parts of Gloucestershire and Dorset will be affected by the hosepipe ban. But the ban doesn't affect Bristol Water and Wessex Water customers. The map below show the area where a hosepipe ban is being enforced:
Richard Fisher, head of Swindon Borough Council's StreetSmart department says the town's parks and flower beds cannot be watered. The council will also have to postpone the opening of its new splash park at Coate Water country park.
The pool is just about to be finished but the hosepipe ban stops it being filled.
Lewis Fox, manager of the Swindon Garden Centre said the hosepipe ban wasn't great news. But he added gardeners can keep beds moist by mulching, using a micro-irrigation system or even using bath water in the garden.
The maximum fine for using a hosepipe is £1000. The last time Thames Water had a hosepipe ban was in 2006. They prosecuted just one person that year. If the dry weather continues, Thames Water will apply for a drought order. That could be in place by early July and would mean commercial water users like window cleaners and car washes have to stop work.
