Start at 3:30 am. Putting plugs in line and getting ready to cut sewer line. Took 2 men and dug out MH #4 and set and tie in. Built invert and ready for paint. Density man came and top lifts on MH #3-2 area passed.
Arrived at 3:30am. Installed two 24" by-pass plugs and started pumps. Checked for leaks and found none. Cored 28" hole in existing MH #1 but could not remove cone due to attached liner. Cut existing 24" sewer, set MH #4 and connected to existing system. Mudded pipes and back-filled around structure. Set riser on #4. Carls concrete cored existing sanitary MH #1. Density tests on all back-fill done yesterday passed.
Larry came out set get dimensions,make and thickness of riser to MH #1. Thompson pump came to check pumps and I told them to install float switches that were in their quote and set up auto dial system. Didn't get connection of 24" sewer to MH #1 because generator quit putting out power and we couldn't finish chipping out the invert. Remaining sidewalk and valley gutter still not complete. Called contractor and left a message. Called for fuel delivery tomorrow due to the two 12" by-pass pumps.
