r JAN 4 1994 BOOK 91 FACE 39877 After the pump was started, the mechanic noticed the walkway on the South side of the clarifier had dropped lower than the rest of the walkway. After further inspection, we found the wall was bowed out a considerable amount. I notified Bill McCain and asked if he could come look at the problem with the wall. Bill looked at the wall and started thinking of ways to keep the wall from moving any more. Jerry Schuckers and Emory Bailes both came up with some good ideas to keep the wall from shifting further South. We presented our ideas to Bill and he agreed that the important thing to do first was to support the wall from the outside. We had some large poles in stock and Ron Lefebure took charge of a four man crew to wedge poles against the South wall. Terry Pinto then instructed us to put poles at the bottom of the wedge poles to keep them from sinking into the ground. After Ron Lefebure's crew placed eleven poles in place, Mr. Pinto put Roland McNeal in charge of the operation. Roland brought in a D-7 dozer and pushed dirt on the poles to help hold them in place. After the dirt was pushed into place, the dozer was parked on the sloped dirt to help hold the poles. During the installation of the wedge poles, Bill notified Risk Management and the Fire Department of the problem. The guide rail and chain was repaired and the clarifier drive unit was operated to check for proper operation. The first time the unit was tested it worked, but then as the tank was being filled, the chain started to jam. The pump was placed back into position, and we started pumping the clarifier out again. During the inspection of the bottom of the clarifier, several big concrete rocks were found and a chunk of concrete was wedged in the chain. The chain had to be broken so that it could be put back on the lower Northwest sprocket. The drive unit was tested and we began to fill the tank. During the time of the repair to the clarifier, we had to store the raw inflow in our surge tank and spare digester. When both tanks became full, Ron Lefebure used the Data Flow system to shut down all the West County liftstations. During this time, six stations went into high level alarms, but there were no sewer back-ups. As the clarifier was being filled, the stations with the highest water level was pumped down first. The clarifier was full and back in operation by 10:30 p.m. Operator, Kevin Gibson, worked from 11:00 p.m. to 7:00 a.m. to watch the clarij!ier operations and pump down the stored .300 gallons. A11'operations were back to normal by 9:00 a.m., Sunday. Below is a list of the County Wastewater crew that worked on Christmas day. As you saw for yourself, this is a hard working crew. When I called and asked them to come in, there were not any problems or complaints.
