Dean Ryan is a significant member of the O & M Support Services team of consultants working on projects supporting the Metropolitan Wastewater Department (MWWD).
Dean Ryan is providing 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). Dean Ryan is responsible for the Metropolitan Biosolids Center (MBC) which is San Diego's new regional biosolids treatment facility. Dean Ryan reviews all engineering construction documentation to develop training documents, site specific training programs, certification training, standard operating procedures, start up training and assistance. It is Dean Ryan's responsibility to effectively interact with other team members, client personnel, regulatory agencies, contractors, vendors and other consultants.
The MBC replaces the City's existing solids processing facility at Fiesta Island and is designed to treat biosolids produced at the Point Loma Wastewater Treatment Plant (PLWTP), the North City Water Reclamation Plant (NCWRP) and any future water recycling facilities in the northern portion of San Diego County. The MBC is located on 39 acres next to the Miramar Naval Air Station. The name Metropolitan Biosolids Center was chosen for three reasons.
Metropolitan emphasizes the regional importance of the facility, Biosolids is the standard industry term for recyclable wastewater solids, and Center conveys the multiplicity of functions for the facility.
The MBC's key functions include: Digesting biosolids generated at the NCWRP; dewatering biosolids produced at NCWRP and Point Loma; producing a range of beneficial soil amendment products; and harnessing methane gas produced during the digestion process to generate the electricity used by the MBC, with any surplus being sold to other facilities or agencies.
Commissioning and start-up of MBC has been divided up into two phases:
Phase I addresses the start-up of the Fiesta Island Replacement Project (FIRP) including the development of student study guides, standard operating procedures, training aids, classroom materials, database management and document control. Phase I commissioning and start-up addresses the Raw Solids Receiving Tank Complex, the Centrifuge Building, a portion of the Chemical Building, the Dewatered Biosolids Storage Building, the Wastewater Pump Station, the Biogas Flare Facility and the Biogas Holding Tank
Phase II addresses the start-up of the Northern Sludge Processing Facility (NSPF). Both FIRM and NSPF will eventually merge to form MBC. The intent of dividing the commissioning/start-up plan into two phases was to allow MBC to treat digested solids from Point Loma while decommissioning and remediating the Fiesta Island Facility, and then at a later date, treat NCWRP solids once NCWRP is fully functional. Commissioning and startup of Phase II involves the remaining MBC facilities and equipment (the Degritting, Centrifuge Thickening, Screening, Digestion and Blending Facilities).
Dean Ryan personnel also provide Commissioning and Start-up services for the North City Water Reclamation Plant (NCWRP) and the Metropolitan Biosolids Center (MBC) facilities. Our Operations and Maintenance specialists have over twenty years experience in the wastewater treatment field. Dean Ryan is responsible for developing several training programs for the North City Water Reclamation Plant (NCWRP). These training programs encompass student study guides, classroom presentations, standard operating procedures, field exercises, regulatory compliance and safety awareness materials. These training programs provide a thorough understanding of the facility operation, thus enabling the staff to to provide quality and efficient service to the citizens of San Diego.
The North City Water Reclamation Plant (NCWRP) is the first large-scale water reclamation plant in San Diego's history and is the largest seweage system expansion in the area in the more than thirty years. Dean Ryan is responsible for the development of Student Study Guides for Influent Pump Stations, Coagulation/Tertiary Filtration, Effluent Disinfection, Chemical Storage and Distribution; Standard Operating Procedures, training aids and classroom presentations and database management. Dean Ryan O & M personnel are members of the Executive Start up committee and are responsible for the development of Unit Process Operating Strategies. The NCWRP is a result of a requirement mandated by the EPA for the City of San Diego to obtain a secondary treatment level waiver for its 180 million gallon per day primary treatment facility at Point Loma. This state-of-the-art facility is designed to treat and reclaim up to 30 million gallons per day of wastewater generated by northern San Diego communities and can be expanded up to 60 million gallons per day in the future. Following tertiary treatment, the reclaimed water is primarily used for landscape irrigation, conserving a significant amount of fresh water. Long-term plans, by the City of San Diego, include repurification of the reclaimed water to supplement drinking water reservoir supplies.
Dean Ryan anticipates we will be actively involved in future actives of the Advanced Water Treatment Plant and the South Bay Water Reclamation Plant.
