How was the 880 remediated (i./e. Stopped and cleaned up)?
Lift Station was turned off and we colsed the force main valve. set up a bypass pump, bypassing the broken
section of force main and opened the bypass valve a head of the brake and pumped the lift station wet well
while the contractor made the repair. City Crews traced how far the sanitary sewer went and set out a pump
and pued the sewer back into the Collection system while we flushed the tributary.
