Greywater recycling projects
Greywater from the kitchen sink contains grease and food particles, which can cause clogging and slow infiltration into the soil. After years of sometimes foul-smelling experimentation, greywater pioneers have concluded that the best way to trap grease and food particles and create habitat for decomposers is with woodchips in a mulch basin, not in a woodchip biofilter.
Year-round greywater reuse in cold climates can be a challenge. What to do with all that water when the garden's under snow? Will greywater freeze in the pipes? Many greywater users divert greywater to a sewer or septic system during the cold season, but it's possible to ecologically dispose of greywater even in the dead of winter.
