MWH Treatment Ltd

Delivering a £40m scheme to design and build Severn Trent Water’s largest sewage works in Burton-on-Trent has been a considerable success for MWH Treatment Ltd.

The contractor, who has been carrying out a major extension of the Claymills treatment works for client Severn Trent Water, has been highly praised by the Scheme for its good practice, already scooping two Silver National Site Awards.

Scheme Monitor Barry Grimes said the site management’s attention to detail in all aspects of this high risk civil engineering project had been “exemplary” and should be “held up as an example to other contractors in the Severn Trent Framework”.

Paying tribute to the Scheme for steering the image of the industry and his own project in a very positive direction is MWH Project Manager Richard Thomson.

The Scheme has done wonders for the image of construction and it is great to reflect on how much improvement there has been throughout the construction industry in all sectors.

Sites appear more professional, are now far less disruptive to local communities, environmental impacts are minimised and stakeholders are better managed.

The workforce is valued and health and safety standards are improved, resulting in less accidents or illness.

The Claymills Team has really embraced the Considerate Constructors Scheme and this has driven best practice on this large and complex project.

Team members have gone the extra mile to minimise disruption to the Burton-on-Trent residents, and businesses, who will realise the environmental benefits from the new sewage treatment works for many years to come.

All clients and contractors in the water industry have really pushed the standards and the Considerate Constructors Scheme has helped encourage and quantify the benefit by rewarding good performance.

Located on the River Trent flood plain, the Claymills ASP project has been especially considerate towards the environment, retaining a storage lagoon to provide a haven for wild birds and newts. It has also recycled 100 per cent of its waste and reduced its CO2 emissions by 25 per cent.

The community has also been greatly considered by the team, with good communications shown to residents, involvement with the local primary school and support to the Claymills Victorian Pumping Station, a working historic utility.

Odour from the modern Bio-P (phosphorous recovery) activated sewage works has also been reduced to the minimum, thanks to a more effective treatment process, and the team has been working with local farmers, installing land drains and repairing sludge pipes to prevent flooding.

Praising the considerable considerate initiatives demonstrated on the project, Scheme Monitor Mr Grimes said: “This site, during its three-year construction period, has consistently operated at the very highest levels that are to be found in the construction industry.”

He said that exceptional cost savings had been made through the re-routing of the site’s main electrical cable, the re-use of cleaned filter media and the use of pre-cast components for the holding tanks.

“The site has consistently worked to help local charities, the Parish Council, farmers, provided school talks and assisted in the preservation of the Victorian Pumping Station,” he explained.

Not without its challenges, the project involved the team modifying the Environmental Agency Flood Barrier and carrying out a high voltage power upgrade to the works while working near to a busy railway crossing and close to local residents, businesses and farmers.


Mr Thomson said:

The project had to be well planned due to its scale and complexity, and resourcing was a key area where we focused on providing the workforce with the best facilities we could due to the long-term nature of the works. This has enhanced the team spirit and benefited performance.

We have used the core values of the CCS to drive best practice at Claymills and we set the team goals of commitment, ownership and trust.

The Monitor’s report gives a really good independent review of the site and encourages high standards. The site reputation has been enhanced by achieving consistently good scores and two silver awards. The whole team are proud of this achievement.

A well-run site is a safer site and our accident-free record is testament to this. The CCS is another tool to help the site managers raise health and safety standards.

Mr Thomson said the Scheme’s Code of Considerate Practice aligned very well with MWH Global’s mission statement “Building a better World”, which is dedicated to fostering good relationships with clients, local communities and MWH’s own employees.

MWH is committed to actively encouraging diversity through its people and activities, and truly believes in the value of a diverse workforce to both inspire its people and grow its business.

Its everyday work is focused on reducing impacts to the environment improving society, while meeting client needs with superior project design and delivery.

Mr Thomson added: “By getting all these right, delivered through our project management, quality, safety, health and environmental management systems, we serve our clients’ needs successfully.”
