Sump Cleaning


Sewage pumping stations are prone to build-up of 'non-biological' matter which floats and forms a layer on the surface of the sump.

Overtime this build-up can prevent float-switches operating and should the layer be drawn into the pumps themselves can lead to a blockage and system failure. To prevent failure and maximise the working-life of the pumps Watlling Hope recommend periodic de-sludging and washing down of the pump chamber. The frequency of sump cleaning depends upon the nature of the connected property, for example a pub may require sump cleaning twice yearly or quarterly whereas a domestic system may only require cleaning once every two years.

Cleaning of the sump is typically carried out in conjunction with a Watling Hope service engineers maintenance visit. Our engineers will be able to recommend a bespoke cleaning schedule for each site thereby minimising costs by only cleaning when necessary.


Grease Problems in Pumping Stations

Grease accumulations on pump station floats

Accumulations of fat, oil and grease are a major cause of pump station problems for both private systems and network systems operated by UK Water Utilities.

Fat, oil and grease (FOG) builds up around pumps, floats and within the pump station pipework / manifold. FOG deposits can lead to premature pump-wear and ultimately total system failure.

However many of these issues can be avoided using effective grease management equipment to either prevent FOG from entering the sump or controlling it as it enters using biological treatment to prevent it leading to problems.

Indeed effective management of grease can dramatically cut-down the need for sump cleaning, in some cases to Zero.
