Comment on this story on the

Despite the recent wet weather and the challenges it brings to a large construction site, work to increase Mogden’s treatment capacity by 50 per cent remains on track for our March 2013 completion date.

The team continue to carry out the installation of mechanical and electrical equipment to get the extension up and running. With this process now practically complete for the new Inlet Works and Primary Tanks, final inspections are beginning to take place, which is the last step before the commissioning process can begin in earnest for these areas.

Work is now almost complete on the first of two new odour control units. This will be ready to capture and treat the odorous air from the new equipment to be put into service shortly.

One part of the site which has been affected by the recent heavy rain is the reduction of the western embankment – where we are gradually moving the soil stored temporarily on the embankment to fill around the new structures.

We are working hard to recover the lost time in this area so we remain on target to lower the embankment to its final height by the end of this year. At this point we will begin a comprehensive planting project to reintroduce various native species of trees, plants and shrubs to improve the outlook.

Thank you for bearing with us while carry out work to improve Mogden, the result of which will reduce the amount of sewage that overflows into the River Thames after heavy rain.

Come and meet the team

On Thursday 26 July, from 5pm to 6.30 pm, we will be holding an informal drop-in session where you will be able to discuss the improvement work at Mogden with members of the project team.

This will be held at Twickenham Stadium. On arrival please report to reception at Rugby House Door A, situated in the South Stand. Free car parking is available in the main car park and refreshments will be provided.

We will continue to update you on our progress, but if you have any questions please call 0845 641 0030 and quote ‘Mogden’.  Our lines are open 24 hours a day.
