REQUIREMENT

We were tasked with specifying and designing two pump sets for a new build apartment block to enable foul and storm water to be pumped separately from the building. Once approved, we were to install and commission the pump sets.

METHOD

• A full site survey was carried out to specify sump dimensions and access cover requirements.
• Monitored the construction of the concrete sump during each phase of the build to ensure they were constructed and installed to our specification.
• Supplied two twin-pump sets and installed them into concrete sump below B2 level (the development has a two storey basement).
• Commissioned the pumps sets and installed the discharge pipe work to the sewer connection at B1 level using electrofusion HDPE pipe.

RESULT

• Liaised directly with the main contractor through every phase of the build to ensure the sump was built to our requirements. This facilitated an easier and more cost effective installation.
• DN80 pumps with an 80mm solids clearance were specified for the foul sump to reduce the risk of breakdowns.
• Each pumping station control panel is capable of connecting to either our own telemetric dialers (optional) or the owner’s building management system. This allows real-time monitoring of both systems from the concierge office or offsite.
• Both systems have battery backup high level alarms in case of power failure.
• Upon completion the client was tasked with incorporating 60 degree benching to the wall/floor joint to direct the waste water towards the pump and prevent dead zone.

 

 

FOCUS ON:

 

CONCRETE SUMP

When forming the structure of a building it can be cost effective to cast a concrete sump instead of using a polyethylene/ GRP chamber.

It is important that the concrete/ waterproof slurry used is signed off by building control to ensure its suitability and ensure no ground contamination can take place.

We can install our pumpset into concrete sumps, using one of our qualified confined entry pump engineers.
