Onsite Wastewater Treatment Systems
Engineered Onsite Wastewater Treatment Systems (OWTS) are employed for commercial and residential sites not serviced by municipal sewers. The State of California as administered by each County, closely monitors and controls the design, construction and maintenance of onsite systems. Inappropriate design, use and maintenance can pose a significant health risk to the general public.
Several onsite systems are available including long used conventional Leachlines and Seepage Pits. Alternate systems such as sand filtration, mound systems and packaged systems can be considered if conventional systems do not meet the required standards.
Geotechnical Design and construction of Onsite Wastewater Treatment Systems commonly requires a subsurface investigation, percolation testing, site (and structure) specific system design, and construction follow-up testing observations.
