Steve I think what you saw would have been as a result of mis-connections - properties connected to an overflow or surface run-off drain instead of the proper foul drain.
There hasn't been a great deal of rain so don't think it would have been as a result of main sewer overflow, but if there was a little it would cause standing matter to be flushed out.
Should be reported to Thames Water and the EA really, then they can make the owners fix it.
If you can get photo's and post them up on Google/Picasa with a precise map location marked it helps (so long as you're OK giving away the location of the swim ha ha!).

The Mogden sewage plant is getting a 50% increase in capacity.

Serious question....does that mean instead of it dumping millions of litres of sewage into the river when we get 2mm of rain, that it will now take 3mm of rain before it dumps millions of litres of sewage?

What a good web page - nice work Dave.

So since June our beloved tidal river has already had 7,504,295 cubic metres of sewage dumped into it.....and that's just the numbers from 4 of the 57 pumping stations Shocked

Take a look at these sludge gas graphs
http://www.thameswater.co.uk/cps/rde/xchg/corp/hs.xsl/923.htm
Why don't TW publish the same style reports for sewage discharges, correlated with rainfall?

Dear Resident

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.

To find out more about the drought, including tips on how to use water wisely, please visit: www.thameswater.co.uk/drought.

Thank you for bearing with us while we carry out this essential work, which will significantly reduce the amount of sewage that overflows into the Thames after heavy rain.

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.

We will continue to update you on our progress, but if you have any questions please call 0845 641 0030, quoting 'Mogden'. Our lines are always open.

Kind regards
------------------------------

If anyone can get along on Thursday and check out the progress, be good to get a report back.

Dear resident,

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.

Dear Resident

After months of preparation, September saw a major milestone in Mogden’s £140m extension.

We have now switched on around half of the new works, including the new inlet area and primary tanks - where solid and heavy particles are removed.

This step has allowed us to start taking the existing uncovered primary tanks on the west side of the works out of service so that they can be upgraded, and then covered to control odour.

We are now gearing up to gradually switch on the remainder of the new works by the end of March 2013. At this point the site's treatment capacity will have been boosted by 50 per cent so it can cope better following heavy rain.

As we get closer to reducing the embankment to its final height by the end of the year, there will be an increase in activity in this area, particularly at the northern end as we remove our construction offices. You may notice some vibration as a result.

We are committed to minimising this as best as we can but we are sorry for any disruption you may experience.

By the end of this month we will be returning to our normal working hours, between 8am and 6pm for the main activities. This follows weeks of working on the embankment until 7pm to recover time lost as a result of this year's unusually wet weather.

Thank you for bearing with us.

Come and meet the team
On Thursday September 27, 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 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 always open.

Dear Resident

We are now into the final phase of Mogden's £140 million upgrade.

This involves gradually bringing more of the new treatment plant into
service and landscaping the site's western embankment.

We are already just weeks away from reducing the embankment to its final
height.

Over the coming months, people living nearby are likely to see an increase
in earth-moving machinery working close to their properties. This will be
particularly noticeable at the northern end of the site – the area
previously occupied by our construction offices.

Section by section, we will carefully be shaping the mound. This will then
be finished with a layer of good quality topsoil, currently reserved in
piles at the foot of the embankment. Unfortunately the nature of this work
will involve some noise and vibration. We are sorry for any disturbance you
may experience, and will do our best to minimise this as much as possible.

Early next year, the embankment will be fully shaped and ready for us to
start planting a range of native trees such as English oak and hornbeam,
and shrubs including holly and hawthorn – encouraging biodiversity and
local wildlife.

Meanwhile, over the embankment, the team are gearing up to bring the next
set of treatment tanks into operational service.

Thank you for bearing with us during this important project. On completion
in March 2013, we will have increased the site's treatment capacity by 50
per cent. This will significantly reduce the need to discharge
partially-treated sewage into the River Thames.

Come and meet the team
On Thursday November 8, 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 and view our landscaping plans.

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
always open.

Dear Resident,

Mogden’s £140 million three-year construction project is drawing to a close.

At the end of March, we will have increased the site’s treatment capacity by 50 per cent so it can cope better during heavy rain. In the run up to this, the project team will continue working hard to switch on each part of the new works – a meticulous and complex operation which began in the autumn.

Over the next few months we also plan to complete the landscaping of the embankment. Although recent adverse weather conditions have affected progress, the shaping of the embankment is almost complete, with the north-west corner of this area following closely behind.

Weather-permitting, we plan to start planting the embankment next month, working from the south to the north of this area. We will be introducing a selection of young native species. This includes trees such as English oak, Scots pine, birch and hornbeam, shrubs such as holly, hazel, blackthorn and hawthorn, and herb-rich grassland – encouraging biodiversity and wildlife.

After March, a reduced number of the project team will remain on site for a short period to get the new part of the works ready to hand over to the day-to-day operations team. During this time we will carry out a number of checks and minor activities, including paving new footpaths, re-surfacing roads, and finishing off any remaining landscaping work that may be delayed by the weather.

Thank you for your ongoing support and patience throughout this project – we really do appreciate it.

Come and meet the team
Our next monthly drop-in session will be held on Thursday 31 January, from 5pm to 6.30pm, for you to discuss the improvement work with members of our project team and view our landscaping plans.

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.

Thank you for bearing with us during this important project which will increase the site’s treatment capacity by 50 per cent. This will significantly reduce the need to discharge partially-treated sewage into the River Thames.

Dear Resident

With construction almost complete, this month we will begin planting the
site's western embankment.

We will create a mixed grass and woodland area using a wide selection of
young trees and shrubs. In addition, there will be a meadow at the base of
the mound with a variety of herb-rich grasses and wildflowers such as
daisies and red campion.

To encourage wildlife we will also build several wood piles, and provide
nest boxes for bats and birds.

In preparation for planting, we have started spreading the area with the
topsoil stored at the toe of the embankment. Once complete, we will install
a shallow land drain in this location. Starting from the southern end, we
will gradually plant each section of the mound.

We have already started operational testing of a large part of the new
works and remain on target to complete the remaining construction work by
the end of March. Once everything has been tested and is running smoothly
we will have boosted the site's treatment capacity by 50 per cent so it can
cope better during heavy rain.

As is usual with work of this nature, some of the project team will remain
on site for a few months to complete the process of handing over the new
works to the site team. This includes optimising the performance of the new
equipment and completing any landscaping work that may have been delayed by
the weather.

Come and meet the team
On Thursday 28 February, from 5pm to 6.30pm, we will be holding an informal
drop-in session, where you will be able to discuss our work with members of
the project team.

This will be held at Twickenham Stadium and free car parking is available.
On arrival, please report to reception at Rugby House Door A, situated in
the South Stand, from where you will be directed to the meeting room.

We will keep you updated on our progress, but if you have any questions
please call 0845 641 0030, quoting 'Mogden'. Our lines are always open.

Mogden update as below folks.

This is fantastic news for the very upper tideway, at last the huge sewage spills will stop. If you have a look through This Data which we get from TW, its obvious just how significant theses upgrades are.

Of course its only part 1, not far way is Hammersmith pumping out millions of tonnes and so on down the river, the Thames Tunnel will stop these if approved but is at least 10 years off and many twists and turns ahead.

What this will do though is protect the nearest pound to the Richmond/ Teddington pound.

There is an open day/launch event in June and more to follow on that, its a real biggie for us even though 1st weekend of the new season.



Dear Resident

We are pleased to confirm that Mogden’s £140 million upgrade is now complete and the extension is up and running.

On behalf of the team, I’d like to say a big thank you for your patience and understanding throughout this important project.

This has boosted the site’s sewage treatment capacity by 50 per cent, which in turn will help to significantly improve water quality in the River Thames.

The project team are set to remain at Mogden until the end of June to carry out the necessary fine tuning of the new works. This is just to ensure it runs seamlessly with the existing site and to make any final tweaks.

You will notice that the embankment is nearly at its final shape. Unfortunately the past few months of wet weather has affected progress at the northern end of the mound, and this has meant a few temporary piles of soil have remained near the mature oak trees. Now the weather is looking better, we can finish off this work over the next few weeks.

We have been able to start seeding the embankment, and also plan to complete this by the end of the month. We will be introducing a variety of herb-rich grasses and native wildflowers such as daisies and red campion which will improve the look of the area as we enter the summer.

Overall, we have now planted all of the hedgerows on the embankment and a third of the trees and shrubs. This, again, has had to be delayed because of the weather. The remaining trees and shrubs will be introduced in November’s planting season to give them the best chance to get established.

Our last drop-in session

We will be holding our last informal drop-in session, where you can discuss the project with members of the team, on Monday 13 May, from 5pm to 6.30pm. As it’s the last session, we will have cakes available so please come and join us!

The drop-in will be held at Twickenham Stadium and free car parking is available. On arrival, please report to reception at Rugby House Door A, situated in the South Stand, from where you will be directed to the meeting room.

If you have any questions in the meantime, please call 0845 641 0030, quoting ‘Mogden’. Our lines are always open.

Finally, we will be marking the completion of this project with an open day on 22 June. For more details, please look out for our newsletter due out later this month.
