Bill Carlson, Utility Foreman, received a call � from the Orono Police Department informing hir_m of • an alarm sounding off at Lift Station #6. At approximately 6 : 06 A.P-s. , Psr. Carlson arrived � at the station, turned off the alarm, inspected the station, and found all pumps out on low � voltage because of single phasin_q. NSP was called at approximately 6 : 10 A.P�. At approximately ' 7: 00 A.M. , NSP was called again. At approximately � 8 : 00 A.PA. , NSP arrived and it was determined that a wire in a lOD amp box had burned out. During • this time, all Lift Stations #7, #8 , #13 , and #22, which feed into gravity lines to Lift Station #6 , � were turned off. � Lift Station #6 was back in operation by 9 : 30 A.M. after which Lift Stations #7, #8, #13 , and #22 were � placed into operation, one at a time, at approximately � one hour intervals. � The procedures used during Lift Station #6 failure were responsive and followed corrective action � methods. Lift Station #6 has never had a failure due to a mechanical problem. In order to avoid � sewer backing up into a resident' s hor.le, who has a flat service line discharging into a flat sewer � lateral, the City has recommended installation of a • backwater value in the discharge line leaving the house. These were never installed at the Breen � residence (now PZr. Tom Frahm' s) and PZr. . Svang' s residence, as have been installed by other residents. ��e have requested the City Engineer to do a study on this area and lift stations to determine hydraulic conditions � that exist and to review whatever steps that can be taken to prevent power failures.
