Laterals serving complexes.

Where a private sewer is to serve a complex of industrial, commercial, institutional, or dwelling structures, special design of the private sewer system to which laterals shall be constructed for each of these structures shall be required. These sewers shall be sized in accordance with metered or estimated water use, using sound professional engineering judgment. Such lateral sewers shall be connected to the public sewer through a manhole. The Commissioner of Public Works and/or Chief Plant Operator and/or Superintendent of Sewers shall determine where this connection to the public sewer is required.

The new sewers and manholes shall be installed and tested in accordance with this chapter.
