The system includes a two-stage biological trickling filter with recirculation to reduce the BOD and total suspended solids to less than 30 mg/L for a design flow of 30,000 gallons per day. Routine water quality results have demonstrated the treatment system produces effluent with BOD and TSS less than 15 mg/L, exceeding the design goals. Treated effluent is reused for landscape irrigation and excess effluent is disposed of in seepage pits. The main control panel includes a SCADA system to allow for local and remote operation and monitoring and alarm notifications.

  • san-lorenzo-1san-lorenzo-2

    The San Lorenzo Valley Unified School District owns and operates the San Lorenzo Valley School Complex in the Santa Cruz Mountains. The complex includes a pre-school, elementary school, junior and high school facilities with a total campus population of approximately 2,500 students and 140 faculty. The California Regional Water Quality Control Board requires the District to remove 50% of the total nitrogen in the wastewater to protect water quality in the San Lorenzo River. FCE designed and supervised the construction of an advanced wastewater treatment system to reduce nitrogen in the wastewater. The system was designed for an average flow of 15,000 gallons per day and uses a single stage trickling filter and two-stage constructed wetland system. Due to the particularly high level of ammonia and low level of carbon in the wastewater a constructed wetland has been a long-term effective treatment system for the campus meeting the State Standards for over 15 years.

  • mission

    FCE designed and supervised the construction of an advanced wastewater system for the Mission Springs Camp and Conference Center located in Santa Cruz County. The campus covers a total of 150 acres and is located in the nitrogen-impaired San Lorenzo River watershed. The California Regional Water Quality Control Board requires a 50% nitrogen reduction in the wastewater before it can be discharged. FCE prepared a comprehensive improvement plan to collect wastewater from the Conference Center, treat the wastewater in a centralized enhanced biological treatment system, and dispose of the water in pressure-dosed leachfields. The system was designed to treat up to 36,000 gallons per day. The treatment system uses an anaerobic baffled reactor (ABR), stacked trickling filter/clarifiers, and recirculation to reduce BOD and TSS to less than 10 mg/L and total nitrogen by fifty percent. FCE included provisions for a second phase of improvements that would include filtering and reusing the treated water in subsurface dispersal. The main control panel is a SCADA-enabled system that allows for local and remote operation, monitoring, and alarm notifications.

  • wildbird

    FCE designed an enhanced wastewater treatment and reuse system for the Wildbird Property. The dramatic property sits over 600 feet above the Pacific Ocean on a granite outcropping that provides very little room for a wastewater treatment and reuse/disposal system. FCE employed an OSI Advantex treatment system that includes an OSI AX 20 treatment pod for enhanced treatment of the wastewater. Treated effluent is reused for landscape irrigation using a subsurface drip dispersal system that irrigates a green roof and surround landscaping. A back up pressure dosed leachfield system was also installed for wastewater disposal during rainy periods.
