Residential System

Lifewater Engineering Company’s offers above ground and below ground ExtremeSTP® residential sewage treatment plants. The above ground units are specifically designed for areas where permafrost, bedrock or other ground or soil conditions make it impractical to install a below ground system. For the above ground systems, the preferred location for discharge is undisturbed, thick, natural vegetation such as a black spruce forest floor, the tundra surface, or a peat bog.

Will operate at -60^oF (-53^oC), provided reliable electrical power is available
will not corrode and never need painting
can be sized for aircraft transport to remote northern communities
utilize submerged fixed film activated sludge aerobic sewage treatment unit
