Can someone advise me regarding a lifting station? We are building a house with a basement. The ground floor is at street level. The basement will be used only as a utility room, with wastewater coming only from the washing machine and a sink. Our area has groundwater pressure, so the basement will be constructed as a waterproof tank ("black tank").
My parents and in-laws each have a lifting station. The general contractor recently offered a small one (“small lifting station Arma-Drainer-Box or Sanifix”). Is it advisable to use a small lifting station or not? What criteria should I consider when deciding?

Hi,
A backwater valve might be sufficient in theory, but only if it doesn’t get stuck...
A sewage lifting station has two functions:

Does the sewage lifting station have anything to do with this, or do you only need the backwater valve, and the lifting station is just to pump the water below sewer level into the sewer?

A sewage lifting station has two functions:
- Raising wastewater to a level where it can flow into the sewer by gravity. For example, when the sewer invert level is higher than your basement sink.
- Raising wastewater above the backwater level. From there, it can flow into the sewer by itself. This prevents basement flooding during sewer overflow because water would have to rise inside the house above the backwater level, which is impossible.
Best regards,
Andreas
