ᐅ Do we need a sewage lifting system, as the architect suggests?

Created on: 4 Nov 2018 15:12

Hello! My architect (very old and always stressed) says that I need a lifting station. However, my sewer connections are 2.5m (8 feet) below the foundation slab. What should I do?
Thanks in advance!

Make a sketch showing the heights of different elements and where the slope and street side can be identified. It’s quite a mess.

Your water drainage system must be positioned above the inspection chamber. Then everything is fine.

The toilet is lower than the sewer line but higher than the connections to the sewer, as mentioned, due to the sloped terrain

If I understand you correctly, your wastewater would first have to flow uphill before it can reach the lower sewer connection. This only works with a pump for the first few meters; otherwise, everything would flow back into the lower toilet.

No, just downward.

My concrete slab is situated at 332.5 meters (1,091 feet) above sea level.
This height also applies to the survey points used by my surveyor. The road runs past on the right side.

Bzp 334 is indicated there. This means the sewer line is higher than the floor slab, so you will definitely need a lifting station. What exactly is unclear now? 🙂
