Comment on this story on the

This month marks an important milestone for the Mogden upgrade project, as we are now entering the final year of work to increase the site’s treatment capacity by March 2013.

With just months left before all the structures are finally formed, work to provide power to the extension is ramping up.

This will allow us to bring half of the new works into service in May, along with a new odour-control plant.

Work to reduce the height of the embankment is now into its second month, and we are working hard to keep dust down for people living nearby by watering the haul routes in this area.  We are very aware of the need to conserve water supplies, particularly in the current drought.  We are therefore dampening the embankment with some of the cleaned water we pump back into the River Thames at the end of the treatment process.

Come and meet the team
On Thursday 29 March, from 5pm to 6.30pm, 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 the Ivybridge Link Centre in Summerwood Road, Isleworth.  Free parking will be available in the centre’s car park and refreshments will be provided.
