A RADIO campaign across Sussex is asking for everyone’s help to reduce demand for water in order to avoid drought measures in the coming summer.
Below-average rainfall in January did little to refill the Sussex reservoirs in time for the expected Spring and Summer demand, and the snow in February was insufficient to make up the shortfall.
As a result the refilling of Ardingly reservoir, which picked up in December, has slowed down and the reservoir is now standing at only 42% full.
The Arlington reservoir near Eastbourne has fared better, and is now at about 75% full, but underground aquifers in Sussex and Kent are still showing no real signs of re-filling.
More than three-quarters of the region’s drinking water comes from aquifers which are filled by rain which soaks through porous ground such as chalk and limestone.
These natural underground water-bearing rocks act like a sponge to absorb rainwater which has percolated its way down through the soil over many weeks and months, and they take much longer to refill than rivers and reservoirs.
The February snow will help, but a foot of snow only produces about an inch of water, and frozen ground makes it harder for water to percolate quickly through the soil.
In the absence of any prolonged periods of rainfall to bring all local water resources back to normal for this time of year, South East Water is now facing the prospect of further measures to protect public water supplies.
“We cannot rule out the possibility that we may have to ask for special powers to abstract more water than we usually do from rivers, and also to restrict customers’ non-essential use of water with sprinklers and hosepipes,” said spokesman Lee Dance.
“Following our Drought Plan we have increased efforts to find and fix leaks in the Sussex and West Kent area, we are carrying out maintenance at water treatment works to ensure they work as efficiently as possible, and also re-routing water around our network of pipes from areas with more water available to allow the reservoirs to recover.”
But consumers need to do their part and a radio campaign across the county is reminding everyone to save water where they can, to report leaks as quickly as possible, install water butts in their gardens and fix dripping taps.
