Storms haven’t ended Cornwall’s drought, South West Water warns

If the last week of wind and rain had you thinking the drought must be over, the people in charge of Cornwall’s water supply have news for you.

South West Water says the recent stormy weather has started to help its water resources after months of exceptionally dry conditions. But some reservoirs remain at critically low levels, and the company says it needs far more sustained rainfall, in the right places, before rivers and reservoirs properly recover.

Why a week of rain isn’t enough

Richard Stanbrook, South West Water’s Drought Programme Director, said the rain had been welcome.

“The recent rain and stormy weather have started to have a positive impact on our water resources, which is welcome after months of exceptionally dry conditions,” he said.

“However, we need much more sustained rainfall in the right places to replenish our rivers and reservoirs and secure a lasting recovery. Some reservoirs remain at critically low levels, and the pressure on supplies remains significant. A week of heavy rain does not undo the effects of a prolonged drought.”

Part of the problem is the ground itself. The company says much of the recent rain has been soaked up by dry soil rather than adding to river flows, so reservoirs are being drawn on more heavily.

Severe drought and the hosepipe ban

The Environment Agency has confirmed that parts of Cornwall, Devon and Dorset have entered severe drought status. A hosepipe ban is in place across South West Water’s network.

What South West Water is doing

Richard said the company is repairing an average of 440 leaks each week, moving water around its network and “taking every practical step to strengthen supplies”.

Around three million litres of water a day are being transferred to the areas in greatest need. The company is also exploring additional water sources and working directly with households and with businesses that use the most water.

What you can do at home

Households and businesses are being asked to keep cutting back on unnecessary water use. South West Water’s suggestions include:

• Keep showers to four minutes or less. A shower uses around 10 litres of water a minute.
• Turn the tap off while you brush your teeth, which could save up to 20 litres each time.
• Check your toilet for leaks. A leaking toilet can waste up to 400 litres a day.

Anyone with a medical condition, a disability or caring responsibilities should carry on using the water they need, the company says.

“We’re asking households and businesses to keep playing their part by reducing unnecessary water use,” Richard said. “Every litre saved helps protect supplies while our resources recover.”
