(A) No person shall make connection of roof downspouts, basement wall seepage or floor seepage, exterior foundation drains, areaway drains, or other surface runoff or groundwater to a building sewer or building drain which in turn is connected directly or indirectly to a public sanitary sewer. Any such connections which already exist on the effective date of this chapter shall be completely and permanently disconnected within 60 days of the effective date of this chapter. The owner(s) of any building sewers having such connections, leaks or defects shall bear all costs incidental to removal of such sources. Pipes, sumps, and pumps for such sources of ground and surface water shall be separate from wastewater facilities. Removal of such sources of water without presence of separate facilities shall be evidence of drainage to public sanitary sewer.
(B) Floor, basement, or crawl space drains which are lower than ground surfaces surrounding the building shall not be connected to the building sanitary sewer. No sanitary inlet which is lower than six inches above the top of the lowest of the two adjacent public sanitary sewer manholes shall be connected by direct drainage to the building sanitary sewer. Building sanitary sewer connections in structures not meeting the criteria of this section will be permitted only if the property owner has:
(1) Installed an individual pumping facility at the structure to receive the building sewage. The pumping facility shall include a discharge pipe with a high point which meets the criteria above; or,
(2) Installed a sewer backflow stop or flap of such nature and design to provide gravity flow to the sanitary sewer system and to prevent sewage backflow into the property improvement.
