Case study on Apartment Complex Sewage & Surface Water Pumping System

Client: FIMA Developments, Newbridge, Co. Kildare.

Address: Tyrone Court, Inchicore, Co. Dublin.

Brief: FIMA Developments were employed to complete a Groundworks Upgrade on a New Apartment Complex, which had stalled and was being finished off by a new Developer.  A complete sewage and surface water pumping solution was required for the large apartment complex to pump both the domestic and surface water generated by the development.

BMS worked with FIMA developments to supply, manufacture, install and commission an appropriate solution.  All pump solutions were by BMS main pump partner, Jung Pumpen of Germany, who are one of the world’s premier dirty water pump manufacturers. 

Firstly, a sewage pump sump and a holding tank providing 24 hour emergency storage was required.  Limited space for installation and ease of installation were important considerations, along with narrow rising mains.  BMS used its experience as the largest manufacturer of GRP (Fibreglass) tanks in Ireland to design, manufacture and install a special ‘all in one’ pump sump and overflow tank with integrated stop and non-return valves to provide a ‘plug and play’ solution.  The tank was comprised of a 5000 l sump separated from a 45,000 l overflow tank by a full length baffle with a cut out.  If there is an electricity cut, the level will rise up in the sump and when it reaches the cut out will begin to flow into the overflow tank.  The baffle contains an integral non-return valve which allows the sewage to flow back into the sump from the overflow tank when the pumps switch back on and the sump level is pumped down.  A Jung Pumpen Dual UFK 20/M Plus Multicut Macerator pump system was installed.  The Multicut system is an extremely robust system which chops up fibrous matter in incoming sewage and also utilises intelligent thrash rejection technology.

A concrete attenuation tank along with a concrete sump were already in place.  BMS supplied an interceptor and hydrobrake to finish off the attenuation tank, along with installed, fitted and commissioned a Jung Pumpen Dual UFK 20/M Plus Multicut Macerator pump system to pump to the local authority sewer outside the complex.

The complex had an underground car park.  A drainage solution was required for the existing concrete drainage sump. An important consideration was the very low invert of the inlet pipe into the sump, which made a conventional pumping solution unsuitable.  BMS proposed, installed and commissioned a Jung Pumpen Compli Dual Pump Package Pumping Station.  The Compli is delivered ‘ready to go’ and can be fully submerged making it an ideal solution for the project.   All pumping stations were supplied with audible and visual alarms along with GSM Dial outs in the event of a fault.
