< . . <br /> Problems Identified <br /> 1) House is not protected from sewer surcharge event. <br /> Suggested Solution: Instali backwater valve in front yard area 7' deep. (See sketch). <br /> 2)The drain system installed at carpoR and inside French drain go to sewer, as does <br /> future balhroom slubs. <br /> Suggested Solution (A): Route drainage to sump pump that pumps to the front yard. <br /> Suggesled Solulion (B): Re-route drainage oulside of house to connect to side sewer <br /> downstream of proposed backwater valve. <br /> Suggested Solulion (C): Disconnect drainage from sewer syslem where adequate <br /> dislance from adjacent steep slopes exist. <br /> 3) Sewer line is flat inside basement. From north wall to side sewer. <br /> Solution: Trench basement and replace lp fix grade issue. <br /> Comments <br /> . All down spouts that are connecled 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.W here downspouts are routed to splash blocks the ground <br /> surface should be sloped away from the house. <br /> • Inslalling a grinder pump would provide increased protection from sewer backups <br /> beyond the protection a backwater valve can provide. <br /> Photos <br /> '� . .T, �i���.}� '� F� rt., ;t� <br /> ,e.
