Sewer project puts 44t drilling platform in Lake Windemere

A 44t drilling platform has been erected on Lake Windemere to enable ground investigations on a £5M project for water comany United Utilities that involves laying a new sewer pipe under the lake bed.

“We need to drill five boreholes in Parsonage Bay along the route of a new pipe, which we are building there next year,” said United Utilities project manager Roger Woodcock. The survey points range from one just offshore to one 150m into the lake. The investigations will take up to two weeks.

The 12m² jack-up barge that acts as the drilling platform was constructed in the lake at Lakeside, near Newby Bridge, and was then towed to its current location in an operation that took several hours. Once floated into position, the jack-up barge platform was lifted clear of the water on four 18m long “legs”.

Geotechnical survey contractor Fugro Engineering Services and sister company Fugro Seacore will carry out the drilling operations. The first phase of work will be finished by the end of March 2012, and work on the pipeline will start in September 2012. The project also includes the construction of a new underground pumping station, and the scheme will roughly double the local sewer network’s capacity for stormwater.
