Hello,
we have purchased a plot of land in a new residential area that runs north to south and measures 16 x 37 meters (north/south 37m (121 feet)). The street is located next to the plot on the east side. We naturally intended to build the house on the northern part of the plot (7 meters (23 feet) from the northern property boundary). Yesterday, we discovered that the water authority has installed the manholes at the very bottom corner of our property by the street. They are supposed to be 1–1.5 meters (3–5 feet) deep. Based on our rough estimates, the sewer pipes would have to be over 30 meters (98 feet) long, as the utility room and bathroom will be located in the northern part of the house. Strangely, both our northern and southern neighbors have their sewer shafts positioned at the northern boundaries of their properties. 😕
Our concerns and questions:
- Could we face problems with the wastewater connection due to the length (pipe slope 1–2%)? We are building a house without a basement.
- Additionally, the street slopes down slightly from south to north by a few centimeters; we want to avoid having to raise the house because of this.
- Isn’t such a long piping system more prone to blockages?
- What are the typical costs per meter for laying wastewater pipes (sewage/stormwater), including the necessary groundwork?

Kind regards

Additionally, the street slopes down a few centimeters from south to north... hopefully we won’t have to raise the house because of that.

- Isn’t such a long pipe run prone to blockages?
gigi schrieb:This varies by region, so someone who has built in your area would be better able to answer. The good news is that once the public portion is completed—from the street to your property—you are allowed to do the digging yourself; this can save a lot of money over those meters.
- What is the cost per meter of installing wastewater pipes (wastewater/rainwater) including the necessary groundworks?
Kind regards
