Cogeneration Project: The scope of this project included 1) installing heat exchangers on the existing Cummins generator to capture the waste heat, 2) utilizing this waste heat to heat the floor of the lined drying bed and 3) constructing a metal building to cover the existing drying bed that measures 315-feet in length and 60-feet in width. The construction of the building was completed on June 20. We have installed the hot water lines from the generators to the floor of the drying bed, and plumbed the heat exchangers to the generator...

Oxidation Ditch Rotor #4 Repair: On September 27, one of our oxidation ditch rotor shafts broke in half. The purpose of the rotor shaft is to support stainless steel paddles that mix and aerate the oxidation ditches. The oxidation ditches are where the wastewater treatment takes place. Fortunately, the failure occurred during the Big Bear Valley’s off-season and we can utilize another ditch that was out of service because of this slow time of year. This rotor was 35 years old and has been in continuous service since 1978. Age and corrosion appear to have caused the failure of the shaft. The new shaft was replaced on January 28, 2014 at a cost of...

Natural Gas Generator Rebuild: The wastewater treatment plant generates all of its own electricity. We have three natural gas generators: two 250 KW Cummins generators and one Waukesha generator with a rating of 600 kilowatts for a total generating capacity of 1100 kilowatts. The Cummins generators are undergoing a complete rebuild of each of the engines. This rebuild is being performed by a combination of Cummins mechanics and our own certified...
