Biosolids Dewatering A sophisticated Biosolids Dewatering System was built and installed by the  CCSD Wastewater Department. In November 2002, the CCSD Board of Directors approved purchase of new Biosolids Dewatering equipment for the Wastewater Treatment Plant.  The system was constructed and installed by employees of the CCSD Wastewater Department and has been operational since 2008. Currently, biosolids from the plant are being hauled to Kern County for disposal. This equipment has significantly reduced waste transport costs and improved the quality of Cambria's waste. The dewatering equipment extracts water from the waste, disinfects and pasteurizes it, resulting in a higher quality end product that can be disposed of locally, and potentially be used as soil amendment.
