More about this product

When planning a large-scale renovation project, the hydraulic design is integral to the overall success of the project. Renovation projects however are often constrained by the location of the existing plumbing and pipework that relies on a conventional gravity-fed system to service all the wet area wastewater.

Designers and architects may consider breaking free from these constraints by using an alternative solution such as a lifting station. When attached to fixtures that drain below the sewer line, lifting stations elevate and evacuate the wastewater to the nearest drainage point on the main drain line reducing the need for expensive core drilling or digging up of concrete slabs. With numerous inlet points sized from 40mm to 100mm, Lifting Stations can accept waste from multiple fixtures including toilets, basins, showers, baths, urinals, bidets, sinks, dishwashers, laundry tubs, and washing machines.

The main consideration for architects and designers is how to select the right lifting station for each project. The major types and features are described below:

Grey Water Lifting Stations

Dedicated Grey Water Lifting Stations can accept wastewater from sinks, basins, showers, urinals, laundries, and kitchens. They are able to pump up to 350 litres per minute and able to withstand higher temperatures through to 90°C, they have an ability to pump water to the maximum 11-metres head (vertically), or up to 110 metres horizontally from the station.

Combination Lifting Stations

These units can accept both black wastewater from toilets together with grey wastewater from sinks, basins, showers, urinals, laundries and kitchens. They are able to pump up to 160 litres per minute, with a single motor option they can accept waste from multiple fixtures and are perfect for granny flats or tiny houses or commercial kitchens.

Twin motor options are suited for larger commercial projects and have been able to pump black and grey wastewater from up to nine complete ensuites to distant existing sewer points.

Newest technology provides an option for twin motor Vortex pumps. With larger open clearance on discharge lines, these pumps can accept waste from multiple fixtures, black & grey discharging up to 13 litres per second. The design of the Combination Lifting Station means it must sit below all the fixtures. It can be located in a pit, and with its IP68 rating, it would still operate for up to short periods if accidentally submerged or flooded.
