ANS:A - house sewers

The sewerage system originates from house sewers. House sewers are the pipes that connect individual buildings (such as houses, businesses, or other structures) to the larger sewer system. They collect wastewater generated within the buildings and convey it to the municipal sewer system for treatment or disposal. House sewers typically extend from the building's plumbing system to the property line or to a connection point with the municipal sewer network. The other types of sewers mentioned in the options—lateral sewers, branch sewers, main sewers, and outfall sewers—play roles in conveying sewage from smaller to larger pipes, eventually leading to treatment facilities or discharge points. However, the initial point of connection for sewage from individual buildings is through the house sewers.
