Residential Wastewater Treatment Systems
Lifewater Engineering Company 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.
Lifewater’s residential ExtremeSTP® sewage treatment plants:
• Will operate at -60°F (-53°C), provided reliable electrical power is available
• Will not corrode and never need painting
• Are sized for aircraft transport to remote northern communities
• Utilize submerged fixed film activated sludge aerobic sewage treatment
• Include UV disinfection
• Include an effluent pump
The following types of systems are available:
• Double-walled, fully insulated systems for outdoor installation above ground
• Single-walled, uninsulated systems for indoor installation
• Single-walled, insulated or uninsulated systems for installation below ground
The following optional equipment is available for residential or small commercial use:
• Arctic outdoor lift station (to lift raw sewage up into an above ground treatment plant)
• Thermosyphon (to keep the permafrost underneath the system frozen )
