Milestone reached on water treatment project

Chorley Wastewater Treatment Works

A joint venture between VolkerStevin and CH2M, called C2V+, has reached a project milestone with an 18-hour concrete pour at a water treatment plant in Chorley.

The C2V+ project team completed the 18-hour continuous concrete pour to lay the foundations for new settlement tanks at Chorley Wastewater Treatment Works.

The project is part of a £14.5M upgrade contract at the treatment works for United Utilities and includes the replacement of two sludge storage tanks, enabling processes to operate in automation.

“This is a challenging project with a huge amount of work to be done to meet the regulatory date of 17 April,” said C2V+ framework director Darren Hynes.

“Most of the large structures are precast off site to minimise the amount of construction on site, improve quality as well as minimising local traffic movements.”

The project began in 2015 and includes the construction of a new inlet works, final settlement tanks and the refurbishment and change of the existing surface aeration plant to a fine bubble diffuser plant.
