Depth of side sewer 10ft from house: 5' 5" <br /> Sewer Report: <br /> Material: concrete <br /> Sewer Length: 70ft <br /> Condition: Bad <br /> Explain: New backwater valve installed in front yard but from the valve to the sidewalk <br /> the line is flat, holding water and worse lots of debris. This could cause the valve to not <br /> close and seal properly when it is needed. <br /> Recommend: Replacement of sewer with trenching. <br /> Problems Identified <br /> 1) Current backwater valve may not function properly because of poor side sewer <br /> condition and the valve does not have anything on it to securely hold it in the proper <br /> position for a tight seal (see Additional Photos). <br /> Solution: Replace side sewer and replace backwater valve with a valve that can be <br /> securely fastened in place. <br /> 2) Side sewer is in poor condition (see Sewer Report). <br /> Solution: Replace side sewer. <br /> 3) (OPTIONAL IMPROVEMENT) Downspouts are connected to the side sewer. This <br /> causes increased flow in the side sewer. They are properly connected to the side sewer <br /> downstream of the backwater valve. <br /> Solution A: Disconnect downspouts from side sewer, extend outfall 3' or more from <br /> foundation, and provide splash block. <br /> Solution B: Disconnect downspouts and install rain barrels to retain rain water runoff at <br /> base of downspouts. <br /> As-Built of Sewer and Plumbing <br /> See attached drawing. <br /> Comments <br /> • All down spouts that are connected to the side sewer could be disconnected and <br /> routed to splash blocks so that less flow is in the side sewer causing potential <br /> surcharge events. Where downspouts are routed to splash blocks the ground <br /> surface should be sloped away from the house. <br /> S:\#Common\clerical\SIDE SEWER&PLUMBING INVESTIGATION\Final Reports\Sewer L Batch\1320 Lombard final.dOCX 4/21/2011 <br />
