REQUIREMENT

We were asked to survey an existing pumping station and to carry out a full refurbishment. Confined entry installation was required. Due to the system being live, we were required to carry out the installation within one day.

METHOD

• Carry out a site survey and produce a report for the client. This included a quotation to replace the internal galvanised steel pipework and guiderails.
• Scheduled a period when the facilities would not be used and arranged for a suction tanker to clear and wash down the wet well.
• Cut out the existing corroded pipework and replaced it with new galvanised steel pipework of the same diameter and configuration.

RESULT

• Galvanized steel pipework offer a long life span.
• The float switches were also changed as a precautionary measure.
• Following our inspection, we judged that the existing pumps did not need replacing as they were quite new.
• Changing the non-return valves, which showed signs of failure, helped prevent costly pump replacement in the future as any backflow / recirculation will be prevented.

 

 

FOCUS ON:

 

REGULAR CLEANING OF THE CHAMBER PREVENTS PROBLEMS

Regular clearing out of the wet well using a suction tanker removes silt and debris, as well as floating wet wipes.

Fat can form a biscuit on top of the water. This can interfere with the float switch operation.
