Exsel Pumps were called with an emergency requirement to supply an over-pumping system to provide duty assist backup for a failing sewage pumping station. Flow requirement was in excess of 1,500 m3/h of raw heavily rag laden sewage.
The call came in late on a Friday afternoon and after initial scoping it was established the best solution would be to install a high flow sewage pump from Exsel's fleet. Pipework needed to be able to accomodate the flow conditions and steel flange pipe with flanged wire armoured was utilised. Within a short time despite the job extending into a Friday evening the equipment was loaded on Exsel’s own vehicles and the specialist installation team mobilised.. The over-pump installation was in place later that evening in time to cover for forecasted rain storms.
Utilising it’s own truck mounted crane to assist in the set up, the Exsel Special Projects Installation Team worked safely and effectively to ensure that the over-pump system was set up and operating correctly before handing over to the site manager.
The project required the set up of a 16” (400mm) discharge submersible sewage pump with a flanged and bolted hose run. The pump utilised was a Hidrostal I16K capable of 3,000 m3/h of flow. The excellent and unrivalled raw sewage rag handling capability being a key requirement as excessive rag had accumulated in the wet well. In addition, the pump was controlled with variable speed drive with level controls so as to not overwhelm the downstream system.
