A pair of new boreholes are being drilled in Sidford this month that will supply two million litres of drinking water to 8,000 East Devon residents. South West Water (SWW) is investing £730,000 installing the boreholes at the Two Bridges Road pumping station to replace one in the Otter Valley, which was dug more than a century ago.

Work will start on the smaller of the two boreholes, which will act as a monitoring point for the main borehole, on Monday, January 23.

Drilling the borehole will take about a week, followed by a three-week period of testing.

Construction of the main borehole will start on or around Thursday, February 23, and take about eight weeks.

Chris Rockey, SWW’s head of drinking water quality, said: “Delivering a clean, safe and reliable supply of drinking water to our customers is our top priority and the two new boreholes represent a £730,000 investment in East Devon.”

A 14-metre drilling rig will be used during construction. The monitoring borehole will be about 120 metres deep with an internal diameter of 15cm. The main borehole will also be about 120 metres deep but with an internal diameter of 30cm.

Mr Rockey added: “All the work is taking place within the boundary of the pumping station site.

“We have written to our neighbours and we will do our best to minimise any impact during the construction work.

“Once the borehole is operational, water from it will be treated with ultraviolet disinfection on site and supplied to customers on the coast of East Devon via the existing water pumping station.”
