A major storm can trigger a natural
flushing mechanism within mains
sewers with the excess foul water
carrying larger quantities of rag and
debris into the works. This can result
in the main invert system being
overridden, choking pumps and
flooding tanks, and perhaps
compromising local water courses.

P&M Pumps identified the
potential for a combined mixing,
aeration and cleaning system that
conditions and deals with problem
solids and rags without causing
blockages. The Stormthrust system
can meet the requirements through
bespoke tank designs (any size and
shape of tank). The system uses a
Vaughan Chopper pump which
conditions heavy solids and creates
sufficient flows through multiple
high velocity venturi nozzles on the
floor of the tank. The result is solids
suspension and, as liquid levels fall,
the system directs flow towards the
drain end of the tank.
