J. Murphy & Sons is pushing ahead with its £3.2m design and build contract for United Utilities at Maryport Pumping Station in Cumbria.
The company’s specialist piling division completed the secant piling of 96, 23-metre deep piles over a nine-week period using two Liebherr rigs. Main excavation works have been completed to intermediate ring beam level and contract completion to ’authorisation to operate’ is due early September.
The scheme is to improve sewer overflows in line with new European standards on bathing waters and shellfish habitats and is part of United Utilities’ five-year, £3.6 billion investment programme to improve water quality and the environment. A new underground storage tank is being constructed by Murphy, together with pumping equipment and pipelines. The tank will hold back up to 5,900 cub. metres of storm water which otherwise would have made its way into the sea.
