The soil mass failure is approx 10'x 30'x 5' deep and dislodged <br />a portion of the 12" dia concrete SD. Soils adjacent to the slump is saturated & more soil movement is possible. <br />A large bolder slide in front of the SD pipe blocking the outlet and creating a surcharged line condition. <br />A review of collection system in the area shows the pipe in generally in good structural condition, however joint <br />slippage is evident. Numerous opened several joints are visible along with voids outside the pipe <br />(LS 65556-65555-67181). <br />The SD pipe is a non-bell type without gaskets, with a tongue length of only a couple of inches. i <br />Despite pipe anchors (MF#2500.010) pipe joints has occurred presumably allowing infiltration/exfiltration. <br />This system was constructed in 1976.
