Case Study: How an Office Solved Basement Wastewater Drainage Without Major Civil Work Using SFA's Sanicubic 2 Classic Lifting Pump
Adding a pantry or washroom to an office basement often becomes a drainage challenge when the space sits below the main sewer line. This case study shows how SFA India overcame that problem using the Sanicubic 2 Classic, a dual-motor wastewater lifting station that delivered reliable drainage without excavation, floor breaking, or disruption to the finished office environment.
Many office buildings are designed with the basement used for parking, storage or utility rooms, not for a pantry or a washroom. So when a business later needs to add these facilities below ground, the drainage rarely falls into place on its own. This case study looks at how SFA India solved that exact problem using the Sanicubic 2 Classic, a reliable dual-motor lifting station that pumped wastewater out of a basement with no gravity fall, no major excavation, and no disruption to the finished office space.
The Challenge: Basement Wastewater With No Way Out
An office was facing a wastewater drainage problem in its basement. Both the pantry sink and the washroom needed to discharge into the main drainage line, but the basement sat below the natural gravity drainage point. Left on its own, the wastewater simply had nowhere to go.
This created a real risk of backflow, slow drainage and foul odour, none of which are acceptable in a working office environment. To make things harder, the basement already had finished surfaces and existing service lines in place. Breaking through the floor for conventional civil work would have meant disruption, mess and downtime the office could not afford.
The Solution: Sanicubic 2 Classic Lifting Station
SFA India recommended the Sanicubic 2 Classic, a floor-standing wastewater lifting station built for exactly this kind of situation. The unit was installed in the office basement to collect wastewater from the pantry sink and the washroom, then pump it up to the available drainage line.
It was placed on a dedicated support frame and connected neatly to the incoming waste pipes and the vertical discharge line. No slab needed to be broken, and no new drainage path had to be dug through the floor. The finished basement stayed exactly as it was, apart from one compact unit doing all the work.
The twin-motor configuration made the real difference here. In an office, the pantry sink and washroom can both be in use at the same time, especially during busy hours. With two motors working alternately, and both switching on together if inflow rises, the Sanicubic 2 Classic keeps up with demand instead of struggling to catch up. If one motor ever needs servicing, the second continues running on its own, so the office restroom and pantry are never left without drainage.
About the Sanicubic 2 Classic
The Sanicubic 2 Classic is a tough, floor-standing wastewater lifting station built for busy commercial spaces and larger residential properties. Its two load-balanced pumps operate alternately under normal use and together during peak inflow, spreading wear evenly and adding a built-in layer of backup.
With 5 inlets, including two low-level side inlets, it connects easily to sinks, washrooms and other fixtures without extra pipework or elevation. Its Pro X K2 grinding system breaks down solid waste before it is pumped out, so it can discharge through a compact 50 mm pipe without the risk of clogging. The motors and level sensors are also designed to be removed easily, which keeps servicing simple.
