Answer 1

Greywater (or greywater, sullage, also spelled gray water in the United States) refers to domestic wastewater generated in households or office buildings from streams without fecal contamination, i.e., all streams except for the wastewater from toilets.

Benefits of using greywater are:

• Freshwater Conservation
• Reduction of water wastage
• Reduced energy consumption
• Reduced chemical consumption
• Reuse of nutrients

Basic Greywater Guidelines

1. Don’t store greywater (more than 24 hours).
2. Minimize contact with greywater.
3. Infiltrate greywater into the ground, don’t allow it to pool up or runoff.
4. Keep your system as simple as possible, avoid pumps, avoid filters that need upkeep.
5. Install a 3-way valve for easy switching between the greywater system and the sewer/septic.
6. Match the amount of greywater your plants will receive with their irrigation needs.
