MEMO TO: File FROM: Russ Zastrow RE: DATE: R_~pair of Sanitary Sewer Service at L13, B2 of Flintwood Hills 2nd Addition December 13~ 1985 On Tuesday, December 10, 1985, I was sent by the City Engineer, Peter Raatikka, to investigate a report of a clogged sanitary sewer service at the above location. Prior to my arrival, an attempt had been made to clear the line with a "sewer snake". This was done under the direction of Dick Carson, the developer. At that time, the cleaner operator indicated that the clog was probably composed of sand and was located approximately 80-85 feet from the cleanout located in the house basement. Upon my arrival, I met with the service line installer and, with him, surveyed the situation in the basement of the residence. Damage to the basement interior was nil. Whatever sewage backup that had occured had dumped over into a perimeter drain sump that was adjacent to the floor drain. This appears to have been minimal and at the time of observation the area was dry. There was no evidence of an odor problem. After locating the general area of the city's service riser, the installer proceeded to break through approximately 1 to 1-1/2 feet of frost and dig up the connection he had made to the city line. In the process of excavating the service, the line was broken and the lines' contents spilled into the hole. Also, considerable cavitation occured both toward the house and under the driveway owing to the sandy, wet soil below the frost line. At Dick Carson's direction, the sewer cleaner was again called and an attempt was made to clear the line from a point approximately four feet from the City's riser. Again, no progress could be made against the clog, as the "snake" would bury itself and could not move the sand. At this point, it was decided that a sewer jet would be required to remove the sand from the line. Roto Rooter was called by Mr. Carson and they said they could be on-site tomorrow a.m.
