WERRE SUBDIVISION, CHUGIAK, ALASKA
This 2,500 gallons per day system is designed to handle the wastewater from nine homes in a ten-lot subdivision. The tenth lot was used for the treatment system. Each home has it's own steel septic tank where the effluent gravity flows into a centrally located liftstation tank. The liftstation sends the septic tank effluent up to a 4,000 gallon steel recirculation tank with an extra 1,500 gallon compartment for filtered effluent discharge to one of two drainfields. One AdvanTex AX100 filter treats the effluent. The entire system was elevated to maintain separation from groundwater.
The developer set up a homeowners association that owns the water wells and wastewater treatment system as a private utility. The association dues pay for the system monitoring and maintenance.
A system like this is a great alternative for subdivisions. Each lot has its own septic tank for primary treatment but the drainfield and secondary treatment are located elsewhere.
Photos of installation and startup are below:

The pod is carefully lifted off the truck and placed in position.
There is a drainfield on each side of the system so there is always a spare.
November System Startup
It was ten degrees out that day. At least the wind wasn't blowing.
