DRC is a member of the O&M Support Services team of consultants supporting the San Diego Metropolitan Wastewater Department (MWWD). DRC developed Unit Process Operating Strategies. DRC provided operations and maintenance support services for the San Diego Clean Water projects at the North City Water Reclamation Plant (NCWRP) and the Northern Sludge Processing Facility (NSPF). Our team reviewed all engineering construction documentation to develop training documents, site-specific training programs, certification training, standard operating procedures, start-up training and assistance and interacts effectively with other team members, client personnel, regulatory agencies, contractors, vendors and consultants. DRC facilitated the development of Metropolitan Biosolids Center (MBC) to replace the city’s solids processing facility at Fiesta Island to treat biosolids produced at the Point Loma Wastewater Treatment Plant, the North City Water Reclamation Plant (NCWRP), and future water recycling facilities in northern San Diego County. MBC’s key functions included digesting biosolids generated at the NCWRP; dewatering bio-solids produced at NCWRP and Point Loma; producing beneficial soil amendment products; and harnessing methane gas from the digestion process to generate MBC’s electrical power and sell surplus power to other facilities or agencies. Commissioning and start-up services for MBC: Phase I: The start-up of the Fiesta Island Replacement Project (FIRP) included developing student study guides, standard operating procedures, training aids, classroom materials, database management and document control. Commissioning and start-up addressed the Raw Solids Receiving Tank Complex, the Centrifuge Building, a portion of the Chemical Building, the Dewatered Bio-solids Storage Building, the Wastewater Pump Station, the Biogas Flare Facility and the Biogas Holding Tank. Phase II: FIRP and the Northern Sludge Processing Facility (NSPF) eventually merged to form MBC. Dividing the commissioning/start-up into two phases allowed MBC to treat digested solids from Point Loma while decommissioning and remediating the Fiesta Island Facility and, at a later date, treat NCWRP solids when NCWRP was fully functional. Commissioning and startup of Phase II involved the remaining MBC facilities and equipment. Commissioning and Start-up services for NCWRP: DRC developed several training programs to provide a thorough understanding of the facility operation: student study guides, classroom presentations, standard operating procedures, field exercises, regulatory compliance, and safety awareness materials. The North City Water Reclamation Plant (NCWRP) is the first large-scale water reclamation plant in San Diego’s history. DRC developed Student Study Guides for Influent Pump Stations, Coagulation/Tertiary Filtration, Effluent Disinfection, Chemical Storage and Distribution; Standard Operating Procedures, training aids, classroom presentations and database management. The EPA mandated the NCWRP for the city to obtain a secondary treatment level waiver for its 180 million-gallon-per-day (gpd) primary treatment facility at Point Loma. This state-of-the-art facility is designed to treat and reclaim up to 30 million gpd of wastewater generated by northern San Diego communities and can be expanded up to 60 million gpd.
