Summary First, the composting toilet eliminates urine and fecal matter from the equation. Second, the baffled tank removes solids from the greywater. Third, the chlorinator oxidizes harmful bacteria. Then the treatment tank serves as a reservoir for the chlorinated effluent and a housing for the pump and float-switch assembly. Here, the rising water-level activates an electric pump which pressurizes the 250' leach-loops uphill. A manual valve enclosed in the valve box partially closes the downhill return stream to build pressure. This injects the effluent into the soil of the leach field. After the pump switches off all excess effluent returns passively downhill for re-storage in the treatment tank.
Schematic
Requirements The designer designed the system to:
1. be fully permitted per current Coconino County permit requirements.
2. minimize energy use wherever possible.
3. include a pump to move the effluent.
4. include a filter to prevent the clogging of drip-irrigation systems.
Remarks
1. To save money I installed this system myself. I rented the heavy equipment from local renters and taught myself to run it.
2. The pump and control box were wired by a licensed electrician
3. The SunMar Non-Electric II Composting Toilet processes the waste from two regular users.
4. This system discharges around 100 gallons of effluent in 15 minutes. If discharge times increase your filter may need cleaning.
5. This system requires two filter cleanings per year. It's a messy job but it extends the life of your pump and conserves electricity.
6. The home is plumbed for a conventional flushing toilet.
