What systems and components are considered basic and advanced?

Basic systems and components consist of sewer lines, septic tanks and aerobic treatments units (ATUs), gravity distribution, gravity laterals, dosed gravity systems, shallow placed gravity systems, lagoons, holding tanks and privies.

Advanced systems and components include sand filters, bio-filters, constructed wetlands, sand mounds, low-pressure pipe (LPP) distribution, subsurface drip distribution (SDD), pressure distribution to conventional sized fields, modified shallow conventional systems and other systems using fill soil.

More information about these systems and components is available on our systems page.
