Ty Gwyn Special School in Cardiff have recently modified their sports facility to incorporate 3 classrooms and numerous ancillary spaces including staff rooms and pupil shower facilities.
T
he old 1960’s sports hall has been divided in two and the best practical design for both staff and children meant the staff kitchen and additional shower room needed to be introduced into the centre of the space. However, this placed them too far from the existing sewer to allow any gravity drainage. In the new location the wastewater from the staff kitchen area (which included a sink and dishwasher) needed to travel through a waste discharge pipe which would be routed 3 meters high into the new ceiling void and then fall for a length of 10 meters into the nearest gravity drain.
The SL designation means the collecting tank is fitted with a Jung Pumpen U3K Spezial submersible pump, manufactured in Germany. This features a large triangular float on a rigid arm external to the pump body, ensuring minimum residual wastewater is left in the tank. This greatly reduces the potential for stagnation when the system is not regularly used.
Ian Mullett, Owner of W. Mullett Ltd, was responsible for providing the installation of the services for this project. He says “We contacted specialist Pump Technology Ltd. because we required a simple yet compact and rugged pumping solution. The system needed to cope with food debris and relatively hot wastewater from the dishwasher, but also be installed inside a kitchen cupboard”

A DrainMinor SL was selected. This unit is designed to fit in a cupboard or under a counter and the lid can be easily removed so the pumping system can be inspected as and when required without the need for any tools.
A key feature of this well proven pump is the fact that it is fitted with a mechanical shaft seal rather than a stationary lip seal arrangement. This means that the submersible pump electric motor is better protected from water ingress. This mechanical seal arrangement has proved superior for higher wastewater temperatures and mitigating against damage from food waste such as coffee granules and milk skin.
