All plumbing outlets from any building or structure hereafter constructed or made available for human occupation and use for any purpose shall, when required by this section, be connected to a public sewer for the District before the completion of the construction of such building or structure or before any occupancy or use thereof or (in the event public sewer capable of serving the building or structure had not been completed by the District prior to the construction or occupancy of such building or structure) within 30 days after written notification from the Board of Sewer Commissioners of the District, as aforesaid, whichever event first occurs.
Any needed repair to a building sewer or connection to a public sewer that is found to be a source of exfiltration, i.e., sewer leak, shall be made within 30 days, and sources of inflow and or infiltration shall be made within 180 days after the date of mailing or personal service of a notice by District staff to the owner of the property served notifying such owner to make such repair.
