As Thames Water drains and cleans tanks
As part of the project to increase capacity at Mogden Sewage Treatment 
Works, we have recently commissioned the new inlet works and primary 
settlement tanks, which are all covered and odour-controlled.
With this extra treatment capacity, we are now taking the existing 
uncovered rectangular primary settlement tanks out of service so that we 
can refurbish and cover them, reducing any odour associated with these 
tanks.  The tanks are located on the west side of the works, and require 
draining and cleaning, which may be temporarily odorous.
There are three tanks to drain and clean.  Draining and cleaning the third 
and final tank will commence on the evening of Sunday 21 October and is 
expected to take 3 days.
We apologise for any inconvenience caused.
