Septic tanks are the most common type of underground sewage and wastewater system for homes where the typical municipal system does not reach. They do the main storage and filtration work of septic systems. The bacteria in the tank treat the majority of sewage solids and nearly all grease from household wastewater.
Septic tanks are available in precast concrete or high-density polyethylene (HDPE). Concrete offers exceptional strength and durability. HDPE tanks combine lightness and easy shipping and handling to enable installations on hard-to-access sites. Both types are corrosion resistant.
Armtec septic tanks are designed to match household needs ranging from 3,600 litres (800 gallons) to 30,000 litres (6,600 gallons).
