Work has started on a £6.3million project to deliver even better drinking water to customers in North Devon.

South West Water is investing £6.3million at Northcombe Water Treatment Works, near Okehampton, to install six new granulator activated carbon filters.

Granular activated carbon is a specially engineered porous material with a large internal surface area - just one teaspoon has the same surface area as a football pitch. Due to its large surface area and special surface chemistry it can remove natural and manmade organic matter sometimes present in Roadford reservoir, which supplies the water treatment works.

Chris Rockey, Head of Drinking Water Quality, explained: "We already have some of the best tap water in the country but this major investment in additional treatment will deliver even better drinking water to our customers in North Devon."

Water that has passed through the GAC treatment process will start being introduced into supply from October 2017.

Chris added: "In the very short term, the smell or taste of chlorine may become more noticeable to some customers. For this reason, we will bring the new filters on line one at a time and blend the new and improved water with the water currently produced by the works to ensure a smooth transition."

This approach was undertaken successfully at Restormel and Wendron water treatment works in Cornwall in 2014.
