Sewage network - distribution and collectors
A system of covered canals (underground) discharging sewage from buildings and other objects to collectors or wastewater treatment facilities.
Data regarding the length of the sewage network, apart from street conduits, include collectors, i.e. conduits receiving sewage from the street network, while they do not include sewers designed exclusively for draining runoff.
