• Do buildings located in private streets have to be connected to the municipal sewer system?
• The building located inside a courtyard has a sewerage system connected to the building on the street. Is it legal? Instead of a shed located inside a courtyard area I want to build a new building. Do I have to connect myself or can I download into the network of the building located facing the street?
• I have drains below the road surface and above the connection exit level. Don't I have to do anything? The courtyard/basement where there are drains feeds directly into the sewer which runs at a lower level, is this correct?
• How should the waste be introduced into the municipal sewer system?
• When are the checks carried out? I already have the eligibility so am I in order?
• Should the Imhoff, Caser or purification facilities be eliminated?
• Which wastewater should I discharge into the sewer?
• What sanctions are incurred for failure to comply with the law?
• What regulations must be respected for discharging domestic wastewater into the sewer?
• Following the modification of the internal sewerage network of a pre-existing building or the construction of a new building, is it always necessary to obtain prior authorization for discharge from the Office?
