Bentley Motors were installing new concrete drainage across their 5.5 hectare site in Crewe. Bentley Motors Limited design, develop, and manufacture luxury motorcars which are largely hand-built.
The Overall Objective
Due to the volumes of concrete being poured there was an issue with some leakage into the lagoons onsite, leading to an increase in the pH levels.
Bentley attended one of our Managing Pollution on Construction Sites CPD courses and as a direct result, asked Siltbuster to provide a suitable treatment solution to effectively treat the pH 10 water to be between 6-9 and subsequently safely discharged.
Siltbuster supplied a PMPU20 unit and installed onsite in November 2015 and has been in continuous use since. The unit has proved so successful that Bentley are now purchasing the unit as a permanent installation.
