Hello everyone,
We are now proud landowners, and the site development is slowly taking shape.
We have just learned that the wastewater pipe on the west side (indicated in green on the sketch) is planned to be connected from our cul-de-sac.
I am imagining our house positioned on the east side to be farther from the main road, with the garden on the west side. My thought was to have the pipe moved further east so that the gap between the house and the pipe would be smaller later on.
However, I was told that the pipe would then be at a higher elevation because it slopes from east to west. This could be important since we want to build a basement with living space, including a bathroom with a toilet and shower.
On the west side, the pipe would be at about -3.95m (-12.9 ft), and further east it would be only around -3.10 to -3.20m (-10.2 to -10.5 ft) deep. At this point, I could still influence the pipe’s location, but after that, I will have to accept it.
Should I just leave the wastewater pipe on the west side as planned? How expensive or difficult is it if there is a larger gap? Should I also keep the other utilities (electricity/water) there?
Or would you recommend having the pipe placed further inside the cul-de-sac? Could the missing centimeters cause problems later in the basement, making a sump pump system absolutely necessary?
Maybe this is also important: The entire new development slopes from south to north!
What experience do you have with this?
Unfortunately, we don’t yet have an architect or general contractor on board to ask. :-/
Thanks in advance.

Where is the difference between extending the sewer line further into the dead-end street, making it higher, or having it end at the marked spot, where it is lower but then the sewer on your private property must have the necessary slope?
If you have to cover the full cost of both options yourself, I don't see any difference. A sewage lift station would be required if a toilet is planned in the basement. Unfortunately, it's probably not a bargain.

Hello,
first of all, thank you for the replies.
My thought was that it would probably be very expensive if the sewer connection is on the "wrong side" and all utilities then have to be routed "across" the property to the house.
Apparently, the costs for a few meters are manageable, so it hardly makes a difference. And regarding the slope, there doesn’t seem to be a big problem either, since the sewer line would still be deep enough when installed. At least, that was the information from the friendly city official. He said that for a bathroom in the basement, only a backwater valve is required.
I think I will have the connection placed in the middle and hope that won’t cause issues later on...

You need a lifting station (lifting unit) to pump the wastewater above the backflow level. For blackwater (toilets, toilet paper, etc.), this requires a proper lifting station, which can cost in the four-figure range. Greywater (shower water, hand basins) can be handled with a small lifting unit, which is typically one order of magnitude less costly.

Hello,
this statement is incorrect.
