Kilndown WTW Civil Engineering Project

Project: Kilndown WTW Civil Engineering Project Client: CMDP (Costain/MWH Delivery Partnership) Location: Kilndown, Kent

Project Introduction

Coleman Construction and Utilities Limited’s contracted civil engineering project scope comprised bulk excavation, new chambers, pipework, drainage and manholes, formation of new roadways and paths, site wide ducting, draw pits and new bases. 

The overall project scope will deliver deep bed tertiary treatment and provision of clean and dirty backwash tanks and includes a new pump station, new mcc panel, new P&FE and a new ferric/alkalinity dosing unit. These works were in support of Southern Water’s directive to reduce the phosphorous from no permit to 0.5MG/L and the FE to 4MG/L identified in the water industry national environmental programme (WINEP3) and required by 22/12/2024. 

Project Deliverables

Challenges and Solutions

A number of challenges have been met and solved throughout the project by Coleman Construction & Utilities Limited. In doing so, the team delivered the project on time and within its budget: 



“Kilndown WTW is a very small site with lots of existing equipment and also buried services and structures. This proved to be a challenge throughout the Civils Phase of works especially during excavation works.

“Coleman worked collaboratively with us (CMDP) to resolve issues with existing buried structures and offered and suggested solutions.

“A total of 126 safe working days were achieved at Kilndown without a single incident which speaks volumes as to the safe working practices which are being upheld by Coleman.

“The level of concrete finishing and quality of work was to a very high standard with comments being made from the client (Southern Water) on several occasions during their visits to site.

“The Civils package was delivered by Colemans on time, within budget and in a professional and safe manner.

“I would like to take this opportunity to thank Billy Rixon and the workforce and look forward to working with them in the future.”
