Where sewers are overflowing from manhole covers there is a risk that watercourses will become polluted. Such incidents can be reported, by any member of the public, to the Environment Agency Incident Hotline on 0800 807060 (Freephone, 24 hour service). Improvements are more likely to happen if incidents are reported.
Separately, the sewer company (locally Thames Water) may offer compensation if you experience sewer flooding in your house or garden. This needs to be reported directly to Thames Water. Check their website for details http://www.thameswater.co.uk/help-and-advice/3018.htm Again, improvements are more likely to happen if incidents are reported to Thames Water as well.
