Three electric submersible pumps supplied by hire specialist, Sykes Pumps, have completed a key assignment at the busy Mancunian Way site in Manchester, following a successful over pumping operation to allow construction of a sewer diversion.

The over pumping project was part of Amey emergency remediation works for United Utilities following a collapse of a section of the Manchester ring road fly over in August 2015. Around 3000 tonnes of the road construction collapsed into the sewer 12 metres below ground and the decision was taken to construct a whole new section of sewer.

Sykes Pumps' submersibles were lowered into the sewer via a seven metre diameter shaft excavated to a depth of 12 metres by the project team. The pumps were then able to pump the sewage and rain water up to ground level and 150 metres across at surface level into a temporary outflow beyond the blocked sewer section, while works on the new section were completed.

One of the pumps has now been removed from site while the remaining two are on standby, pending repair works to a sewer junction between the Mancunian Way and Hoyle Street, which will require a further over pumping scheme. Once these works have been completed, the remaining road infrastructure will be reinstated enabling the Mancunian Way to be fully opened to traffic again.

Comments Mike Cook from Sykes Pumps: "The Mancunian Way is an important part of Manchester's road infrastructure designed to reduce traffic in the city centre.

"Addressing the damage caused by the collapse last year has been a painstaking process and the over pumping operation using our electric submersibles has played a vital role in ensuring that the sewage system could cope during this challenging period."
