Hosepipe bans in force as drought declared - is your area affected?

Drought declarations have been issued across significant portions of England and the entirety of Wales due to excessive heatwaves depleting water supplies. The Environment Agency (EA) reports that more than half of England is now in drought, with the most affected regions being central, eastern, and southern areas. Wales, too, is experiencing drought, following an extension of the measure initially implemented for North Wales and the Upper Severn river basin by Natural Resources Wales (NRW).

Both England and Wales are on track to record the driest July on record, compounded by hot and dry conditions throughout spring and early summer, as well as heightened water demand. Over 20 million individuals in England and Wales have now been mandated to adhere to a hosepipe ban, prohibiting the use of hosepipes for gardening, vehicle washing, window cleaning, and pool filling.

Determining drought or water scarcity involves evaluating current water resources against weather forecasts. Both conditions can result in hosepipe bans. While drought is caused by extended periods of dry weather, water scarcity arises when water demand surpasses the available supply. This summer, restrictions have been implemented in certain areas to manage high demand.

However, the unusually hot summer has raised concerns about the UK's preparedness for drier summers anticipated due to climate change. Eight UK water companies have already imposed hosepipe bans, with seven located in central, southern, and eastern England, and one in Wales. England's drought covers East Anglia, Hertfordshire, and the entire London, Thames Valley, Hampshire, Isle of Wight, Devon and Cornwall, West Midlands, and Wessex regions.

Several other areas of England are experiencing prolonged dry weather, falling below drought status, while Yorkshire and the North East remain unaffected.

Wales is also under drought conditions, with Natural Resources Wales (NRW) stating that sustained high temperatures are deteriorating the natural environment. Northern Ireland does not currently have any official droughts, and Scotland does not declare droughts but monitors water scarcity, with several areas in significant scarcity.

Scotland's main sources of water are rivers, reservoirs, and deep underground sources. The Environment Agency (EA) has noted that nearly 80% of England's rivers are experiencing flows below normal or lower due to the hot and dry weather. Reservoirs are crucial water sources, but England's reservoirs are below average levels for this time of year, especially in South-east England, which relies more on groundwater.

Groundwater levels in June were generally at or just below normal after winter rains but have been depleted by a drier spring in most regions. Groundwater responds more slowly to climate changes than rivers, leading to longer-lasting droughts if they occur. Droughts result from a combination of natural and human factors, with the Met Office predicting drier summers as the world warms.

However, there is no clear trend so far. Warmer temperatures draw more moisture from the soil, exacerbating water depletion in rivers, reservoirs, and the soil. This can lead to rapidly onsetting droughts, heatwaves, and wildfires. Water companies in England and Wales have been criticized for underinvestment in water infrastructure.

The government and water companies are planning nine new reservoirs for England by 2050, with one under construction in Hampshire. Additionally, measures such as hosepipe bans and smart meters may be necessary to control water demand.
