Methodological explanations
A residential building is a building structure where at least half of the total usable area is used for residential purposes. In cases where less than half of the total usable area is used for residential purposes, such a building is classified as non-residential, in accordance with its intended use.
Sewerage is a complex of sewage facilities: sewage networks, outlets of devices used to introduce sewage into water or the ground, and devices for pre-treatment and purification of sewage, as well as sewage pumping stations.
