ᐅ Lifting station or gravity drainage for sewer lines over 40 meters

Hello everyone,
for our new build on a hillside, we need a lifting station to connect to the sewer on the upper street.
Alternatively, it would be possible to connect through the neighboring property to the sewer on the parallel street below the building. However, this would require installing pipes of about 40m (130 feet).

What do you think? Which option makes more sense in terms of costs (purchase and installation/maintenance of the lifting station vs. pipe installation)?

You can only really know once you have specific quotes.

Having pipelines on the neighbor’s property is always a bit tricky. "If the worst happens."

Generally, I prefer the approach of "I don’t want to rely on the neighbor or use their land," but the costs for a lift station and its maintenance/repairs should not be underestimated.

Has the neighbor already given approval? Any conditions or restrictions?

If the earthworks are not too expensive, I would go for the technically simple and maintenance-free solution with the long conduit. But then make sure to properly secure the right of way in the land register. This will probably also mean that you’ll have to offer the neighbor more than just a crate of beer.

It also depends on the type of property and what is already installed along the proposed conduit route...
And how much actually crosses the neighbor’s property.
Also to check: over 40m (130 feet) with a 2% slope equals 80cm (31.5 inches). Plus 80cm (31.5 inches) for frost protection, that’s already 1.6m (5.25 feet). Is the sewer connection still deep enough then (usually it is, but better to verify).

No, I still need to obtain that as well..

The plot is currently just a "meadow" and not designated as building land, and the owner moved away a long time ago. Therefore, I actually see the chances as quite good.
