PROBLEMS at a sewage pumping station left people in a hamlet near Truro with flooded gardens when bad weather struck.
South West Water (SWW) admitted the pumping station was "unable to cope" and has apologised to residents of Calenick.
Rachel Damerell, who lives on Ropewalk Terrace, said: "We had repeated spillages of sewage. Largely as a result of the very heavy rain and the inability of the SWW pumping station to cope with that."
Steve Chamberlain, Cornwall Council member for the area, visited following the flooding and said: "My concern is that the drains that were installed to overcome this kind of episode seem to be clogged with resurfacing gravel as much as mud and they were not cleaned out in anticipation of this kind of weather."
A spokesman for SWW said: "Electrical problems with the pumps at Calenick sewage pumping station meant they were unable to cope with the large volumes of surface water entering the sewerage network. Waste water backed up into the sewers feeding the pumping station and flooded through manholes into nearby gardens.
"Staff operated the pumping station manually until replacement parts arrived later the same day. We have since thoroughly cleaned the area.
"We do appreciate how unpleasant sewer flooding is for affected customers."
