2) Side sewer is in poor condition has sags or"bellies", areas with no slope, and it <br /> appears that it was repaired in the past using improper materials. This could cause <br /> future blockages and flooding. <br /> Solution: Replace side sewer by trenching. <br /> 3) Downspout is tied into side sewer upstream of backwater valve. During a surcharge <br /> event when the backwater valve closes storm water from this downspout may back up <br /> into the house and cause flooding. <br /> Solution: Disconnect downspout from side sewer, extend outfall 3' or more from <br /> foundation, and provide splash block. Cap or plug existing downspout line in the ground. <br /> 4) Basement stair drain is upstream of backwater valve. During a storm event when the <br /> backwater valve closes surface water that enters the drain could flow back into the <br /> basement. <br /> Solution: Install sump pump for rain that routes storm water to the yard during storms <br /> where the system surcharges. <br /> As-Built of Sewer and Plumbing <br /> See attached drawing. <br /> Comments <br /> • Down spouts connected to the side sewer could be disconnected and routed to <br /> splash blocks so that less flow is in the side sewer causing potential surcharge <br /> events. Where downspouts are routed to splash blocks the ground surface <br /> should be sloped away from the house. <br /> • Installing a grinder pump would provide increased protection from sewer backups <br /> beyond the protection a backwater valve can provide. <br />
