The extensive 50-week project comprised an upgrade to the existing 40m3 Caustic Dosing Facility, a new Tertiary Treatment Plant, converting/upgrading the existing Pumping Station, upgrading the Sewage Pumps, a new 12.5 metre diameter Radial Settlement Tank, a new 31 metre diameter Trickling Filter, new cross site pipework and ductwork installations and an upgrade to the site power supplies and telemetry to meet the Environment Agency and Water Industry National Environment Programme requirements.

Our scope comprised bulk excavation, new chambers, pipework, drainage and manholes, roadways and provision of hardstanding’s, site wide ducting, draw pits and new reinforced concrete bases and structures. The construction of the new Humus Tank represented our first experience with this type of project and involved the creation of a complex concrete structure within a 20 metre circular cofferdam, extending over 6 metres in depth.

The final deliverables of the project included a road extension to enable the large tankers to manoeuvre more easily, reinstating footpaths and landscaping, drainage pipework and concreting footpaths to the Humus Tank.

“Coleman Construction & Utilities’ performance at Lingfield has been instrumental in ensuring the successful progress of this key project. The quality of work has been exceptional throughout all the stages of the project from the upfront preparations right through to the end. Safety and compliance have been adhered to and they have consistently demonstrated a commitment to performing to the highest of safety standards. This was despite some very challenging work interfaces, including deep pipelines/ excavations, cofferdams and large concrete structures. Communication and collaboration throughout the project have been excellent and it has been a pleasure working with CCU on this Scheme.”
