Open Meeting Thursday 31st May
With less than a year to go before we increase Mogden’s treatment capacity by 50 per cent, preparations for the commissioning of the new works are ramping up.
This involves a rigorous testing process, which is currently underway to ensure the new structures are fully watertight and all the new equipment operates correctly before we start to use it.
This process is nearly complete on the new inlet works and primary settlement tanks – where we will remove grit, rags and the heaviest solids from the large volume of sewage that enters the site.
Next in line are the recently completed aeration lanes – where we pump air into the wastewater to encourage naturally occurring micro organisms to break down the organic matter.
In order to conserve as much drinking water as possible we are using treated water from the works, known as final effluent, for the testing process. This final effluent will be reused to test each of the five aeration lanes, cutting water usage by around 80 per cent – equivalent to the daily water use of around 1 million people.
Elsewhere, work to reduce the height of the western embankment is entering its fourth month, with soil being removed at a steady pace as we continue to fill around the recently completed tanks. We are also using final effluent here, to damp down the soil on the western embankment where necessary to minimise dust.
Thank you for bearing with us while carry out work to improve Mogden, which will reduce the amount of sewage that overflows into the River Thames after heavy rain.
Come and meet the team
On Thursday 31 May, 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 hour a day.
