About this Project

Our team designed and supervised the construction of a two-stage trickling filter system for a 61 home affordable housing project on Pinto Lake in southern Santa Cruz County.  The system was designed to reduce the BOD and total suspended solids to meet secondary treatment standards of 30 mg/L for a design flow of 20,000 gallons per day.  Routine water quality results have demonstrated that the treatment system produces effluent with BOD and TSS concentrations of 15 mg/L, exceeding secondary treatment standards.  Treated effluent is reused in a subsurface drip dispersal system to irrigate a soccer field in the community.  A pressure dosed leachfield was also installed and is used during non-irrigation periods.  The main control panel includes a SCADA system to allow for local and remote operation and monitoring and alarm notifications.
