Wingham WTW

Project: Wingham WTW Client: CMDP (Costain/MWH Delivery Partnership) Location: Canterbury, Kent

Project Introduction

Coleman Construction & Utilities Limited has received high praise during the completion of its civil engineering sub-contract for Principal Contractor CMDP JV, on behalf of Southern Water. The works encompassed a new WTW Ferric Dosing package and was secured off the back of Coleman Construction & Utilities Limited’s (CC&UL) previous contract delivery, company progression, safety performance, as well as the quality of their workmanship. 

Coleman Construction & Utilities Limited’s contracted civil engineering scope comprised bulk excavation, new chambers, pipework, drainage and manholes, extension of a roadway and provision of hardstanding’s, site wide ducting, draw pits and new reinforced concrete structures, including a new LV kiosk base. The total amount of concrete poured was 673m3, including a single pour of 128m3, the largest to date on any CMDP JV project.

These works were in support of Southern Water’s wastewater directive to reduce the phosphorous from 1.0mg/l to 0.08mg/l in line with the new permit (Driven by Habitats 1 and No Deterioration 2).

The contract was underpinned throughout by a collaborative approach with CMDP JV and Southern Water, as well as other project stakeholders, providing the basis for proactive communication and highly coordinated activities, resulting in the safe and successful completion of this wastewater civil engineering project – meeting time and budget requirements.
