Clean water in the pipeline

Posted: Monday 22nd January 2007

Mid Kent Water is spending nearly £1 million to improve water supplies in the Charing and Challock areas.

The company is using the very latest technology to remove minute traces of nitrates from water that has percolated into the underground sandstone aquifer in the Charing area.

An ion exchange unit has now been installed at Charing Pumping Station to convert the nitrates to harmless chlorides and safeguard the supply.

Increased levels of nitrates in water are usually associated with the historic use of agricultural fertilisers which often takes decades to filter down to the water table.

Water Quality Manager David Smith said: “Although the quality of water supplied to customer’s homes has remained at a very high standard, we are taking action now to safeguard this valuable source of water for the future. We have had a slight rise in nitrate levels at one of our borehole sites and this equipment will ensure that the source can be used not only for this generation but for generations to come.

Charing Pumping Station has four boreholes drilled deep into the sandstone aquifer and can supply up to 4.5 million litres of water a day to a population of 12,000 people in the area.

The £960,000 scheme is part of Mid Kent Water’s £25 million annual programme of improvements to water resources, leakage and water quality.
