Q. 7 Sewage installation
31. Dwellings are considered as having installations for a sewage system when the housing unit uses a piped system for draining waste water that is connected to a public sewage disposal plant (mark an x will in the box for code 1), as well as when the dwelling has available a piped system for draining waste water to a place that acts as an absorbent pit (mark an x in the box for code 2).
The following answers will be checked for consistency:
- If in Q.6 - hot water supply installation - an x mark was recorded in the box for code 1 or 2 (from the public network or from private/own system), then Q.7 - sewage installation - an x mark has to be recorded in the box for code 1 or 2 (from a public network or from private/own system).
