General cold condition greywater suggestions
- Continuous downhill slope in all collection and distribution plumbing. No standing water = nothing to freeze. Branched drain systems are a distribution system with continuous downhill slope.
- Clear discharge outlets. At least six inches of fall from the greywater outlet to the surface the water lands on will prevent the outlet from plugging with ice. The ground should slope away steeply from the outlet at first, then may gradually flatten—transitioning from say, 4% slope to 1-2% within the four feet of the outlet.
- Insulate the system.
- Burying the pipes in the soil and covering them with mulch will certainly provide some insulation.
- Mulch basins generally will stay unfrozen well above frost line, because of heat from applied greywater and composting, held in by insulating mulch and snow above.
- The composting heat can be cranked up by adding plenty of carbonaceous yard waste in the fall (leaves, for example) then adding nitrogen throughout the winter via the greywater (by peeing in the shower, for example).
