The owners of any building sewer having such connections, leaks or defects shall bear all of the costs incidental to removal of such sources. Pipes, sumps and pumps for such sources of ground water shall be separate from the sanitary sewer.
(2) Missing or damaged sewer cleanout covers, or any rainfall inflow to city sewer:
Impact | Action Taken |

(b) The minimum depth of a building sewer shall be 18 inches;

Where existing wye or tee branches are not available, connections of building services shall be made by either removing a length of pipe and replacing it with a wye or tee fitting using flexible neoprene adapters with stainless steel bands of a type approved by the Superintendent. Bedding must support pipe to prevent damage or sagging. All such connections shall be made gas-tight and water-tight;
