Depth of side sewer 10 ft from house: 4 ft from house depth was 4-5 ft. but the line was under stairs could be a 2 ft dig. Sewer Report: Material: Concrete Sewer Length: Unknown Condition: Holding water and would not let the camera get past, camera is 1.25 inches and drain is 4 inch. Explain: Could not get past the stairs, camera showed water and debris, line needs to be snaked or jetted to try to clean it out for further evaluation. Recommend: Replacement with trenching will probably be needed. Further evaluation of the side sewer after it is cleaned could determine full extent of repair needed. Problems Identified 1) This home does not currently have a backwater valve to prevent backups during high flow surcharge events. Solution: Install backwater valve upstream of all downspout and exterior drain connections. See attached site drainage and plumbing sketch for proposed location. 2) Side sewer is in poor condition, and was holding standing water during inspection. Solution: Replace side sewer via trench excavation and ensure adequate constant grade towards sewer main. 3) Downspout line on south side of house is restricting the flow of water. It seeps out at bottom of basement stairs; this could lead to basement flooding during a storm event. Solution: Disconnect downspouts from underground system, extend 3 feet minimum from building, and route to splash blocks. Where downspouts are routed to splash blocks the ground surface should be sloped away from the house. As-Built of Sewer and Plumbing See attached drawing. Comments • All down spouts that are connected to the side sewer could be disconnected and routed to splash blocks so that less flow is in the side sewer causing potential surcharge events.
