The sewage works in Mogden, west London, are currently being overhauled and upgraded to bring them into the 21st century. At an estimated cost of £140m the works will reduce the amount of storm sewage that gets pumped into the Theames when the system becomes overloaded.
The first part of the works has nearly been completed, with nearly 500,000 tonnes of soil being moved from the western Thames embankment so new treatment equipment can be fitted. It would have taken over 750 trucks per day to move the amount of soil that needed to be moved, so to speed up the process, the soil has been left on site while the works are completed and then used around the site. When the work is complete, the embankment will be planted with native tree species and hedgerows to encourage a natural renewal of the area.
Thames Water project manager Matt Warburton stated:
“The improvement work is progressing really well. We have now started to prepare the foundations for the additional sewage treatment equipment, which involves driving steel and concrete piles 12 metres into the ground.
“After Christmas, most of our activities will take place further within the site, and will therefore be less noticeable from neighbouring properties.
“We will, as always, continue to monitor noise and limit disruption as best we can. This includes continually reviewing our working techniques. We would like to thank residents for their ongoing patience during this essential work.”
