THE first phase of the controversial £140million upgrade to Mogden sewage works is almost complete.
Thames Water has moved more than 450,000 tonnes of soil from the western embankment to make way for new sewage treatment equipment, which has temporarily resulted in the embankment being higher than it will be when work is finished.
In October, the Chronicle reported how the piles of mud were overshadowing the home of Michelle Chisholm, who lives in neighbouring Harvesters Close.
A spokeswoman for Thames Water said: "This has avoided the need for 750 lorry movements per day in and out of Mogden over the past three months. The soil will gradually be used to fill around each new structure as it is built between 2011 and 2012."
Last Thursday, Thames Water held an informal drop-in session at Twickenham Rugby Football Union for people who wanted to find out more about progress and provide feedback.
Matt Warburton, Thames Water's project manager, said: "The improvement work is progressing really well. We have now started to prepare the foundations for the additional sewage treatment equipment, which involved 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 would like to thank residents for their patience during this essential work."
The utility giant also has plans to plant the new embankment with native trees and hedgerows to create new habitats for wildlife in spring next year.
Residents hope the finished work will reduce the smell that has blighted their homes for many years. .
