Connect New Main to Existing Manhole

    • 2.3.8.D. New sewers to existing manholes:
      • The base of the manhole shall be core-drilled in accordance with Section 3.16.4 and an appropriate seal boot, per Agency’s approved materials list, shall be used to positively seal against infiltration and exfiltration. Break-in connections shall not be permitted. The flow channels in the bases of existing manholes to which new sewers are connected shall be modified in accordance with Section 2.3.19.b to provide for efficient passage of wastewater flows. Manhole flow channel modifications shall generally conform to Standard Drawing SD-9. Where the new sewers are larger than 15-inches in diameter, the connection requirements to existing manholes will be determined on a case-by-case basis. The Engineer shall contact the Agency as soon as possible in the Project design process to determine sewer connection requirements.
