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?

Sebastian7924 Aug 2016 08:30The question is: For what purpose?
I have installed two systems in the basement – one is a sump pump basin that collects wastewater from the washing machine, two washbasins, the shower, air conditioning condensate, and the heating overflow. It can also help reduce flooding to some extent.
For this, I installed two submersible pumps that are set up with fail-safe controls to back each other up.
Then, I have the classic macerator pump, a Sanibroy. It only pumps sewage upwards and is located in the room next to the bathroom.
In your case, I would also install just a sump basin with pumps, but no complete macerator system.

Yes, exactly. The question is: for what purpose? Do I even need anything, or can I skip all that stuff? When do you use something like this, and when not? Backwater valves are also a topic. I’m not familiar with this area at all and don’t know what I should plan for, or if I need any of it at all.
There was an incident where it rained so heavily that the sewer system couldn’t handle the water and pushed it back through the drains onto the street (though that must have been about 15 years ago).
Does the sewage lifting unit have anything to do with this, or do you only need the backwater valve for that, with the lifting unit just used to pump water from below sewer level into the sewer?

A lifting station is used to raise wastewater/sewage from the basement to the sewer level, allowing it to then flow away normally by gravity.
A backwater valve is installed to prevent external impacts such as sewer blockages or unwanted intruders like rats.
If there are no toilets in the basement and none are planned, using submersible pumps (preferably two pumps for redundancy, each on separate circuit breakers or electrical circuits, with float switches at two different levels) along with a sump pit is a more cost-effective solution.
Backwater valves come in mechanical and electrical types. Mechanical valves are cheaper but tend to close improperly over time due to deposits and may fail when needed. Electrical valves are more expensive; they open and close at regular intervals to stay operational, require power, and should be easily accessible. How they behave during a simultaneous flood and power outage is uncertain.
