No more £££ diesel as M&C Engineering keep sludge moving with Borger Pump
M&C Engineering has helped awater company bring an end to a costly and time- consuming diesel pump application, by introducing a newskid-mounted unit from Borger.
Whilst a tankwas being replaced at a treatmentworks, thewater companywere paying significant hire and running costs, as well as dealingwith excessive noise – but the flowis nowbeing diverted by a 24.4kWBorger EL 1550 pump,which has been skid-mounted
byM&C Engineering,who also supplied valves, control panel and canopy.
Richard Shipp, Director atM&C Engineering, a full turnkey services provider, said: “We’re very impressedwith Borger, as is our customer. The newpump has been running 24/7with no problemswhatsoever. The diesel pumps that were at the plantwere very hungry and expensive to run – and although this is a temporary set-up to keep the RAS (Return Activated Sludge),moving, the Borger pump is
lined up for a permanent installationwith our customer,making good use of CAPEX”.
Benefitting fromitsMaintenance-In-Place design,which requires only basic tools for servicing, Borger’s self-priming rotary lobe pumps are provenworldwide across a multitude of industries, aswell as inmunicipal wastewater treatment.With a reversible flow option, Borger’s rotary lobe pumps are also suitable for loading and unloading applications.
Adoption of Sewage Pumping Stations challenged by household wipes
One of the biggest problemswhen pumping domestic sewage is the volume of household wipes that enter the sewage system. Current specifications for Sewers for Adoption realistically only cater for normal domestic sewage beforewipeswere introduced into everyday life.
Newdevelopments,where a sewage pumping station is required, are having to prove the stations compliance to specification and reliability before the localwater companywill adopt the pumping station.
Many builders and developers are facing 28
difficultiesmaintaining reliability of the pumping station during themaintenance period leading up to adoption due to continual failure because of ragging up and blocking of the pump(s).
The failure is caused by vast volumes ofwipes and fibrousmaterial collecting and inundating the pump(s),with somuchmatter creating a blockage leading to pumping station failure.
Normally the failure is identified early enough by built inwarning systems to prevent an environmental event, but this is not always the case, resulting in environmental consequences.

Many builders and developers have tried to educate residents thatwipes and fibrous materials should not be disposed of via the sewage systemwith limited success.
A Bloor Homes development on a site in providing 500+ newhomes had severe blocking problemswith an adoptable pumping stationwith regular failure after commissioning,which became aweekly event.
T-T Pumpswere asked to investigate and itwas identified that surges ofwipes arrived in such volume to cause the pumps to block. The installed pumping station designwas fully
