Meet the contractor: COMA/Wessex Water
If you live in the South West you’re probably already familiar with the name Wessex Water. They provide water and sewerage services to 2.8 million customers across Somerset, Dorset, Bristol, Wiltshire, Gloucestershire and Hampshire. Wessex Water is also involved in the Hinkley Point C project – providing utilities and construction services through the Construction Operations Maintenance Alliance (COMA).
Q. Tell us a bit about COMA and how it’s supporting Hinkley Point C
A. The Construction Operations Maintenance Alliance (COMA) is a partnering arrangement led by the Wessex Water Group. We bring together local contractors and suppliers from the south west to work on large infrastructure projects, such as Hinkley Point C.
The benefit of having one alliance is that we provide a single, sustainable, end-to-end solution for infrastructure projects. Ultimately, this saves money, reduces waste, and adds long-term value to local communities and the economy.
Q. How long has COMA been on site?
A. Wessex Water began working on site since November 2015, with some of our people seconded into the NNB (Nuclear New Build) site operations team at Hinkley Point C. It was in June 2017 that COMA came into being, when Wessex Water was awarded the contract for delivering construction utilities operations and maintenance team services at Hinkley Point C.
The contract scope covers the design, build, operation and maintenance of all temporary site utilities – including waste and surface water network, as well as all electrical supplies and sub stations outside of the main construction areas, until the reactors are commissioned in 2025 and beyond.
Q. What sort of services does COMA provide?
A. We deliver the following services on site:
- Waste and water management: managing the waste and clean water networks
- Asset management and permitting: ensuring adherence and acceptance of policy and procedures
- Project delivery
- Compliance and performance monitoring: operation and management of consented discharges and compliant sampling
- Electrical services: along with controlling all work on electrical apparatus
