1) Factors Affecting Approval of Greywater Systems
2) Types of Systems 3) System Capacity



It is important to recognize the definition of blackwater, and that blackwater can be generated by what would usually be considered greywater sources. For example, homes with babies or ill individuals can generate wastewater classifiable as blackwater out of clothes washers.

Wastewater systems that incorporate greywater irrigation should permit flexibility in response to occupant's wastewater patterns, seasonal variations in demand for irrigation, and weather. This system would entail a separate sewer or septic connected blackwater system that is linked to the greywater system for overflow and other backup purposes. However, the fact that blackwater can occasionally be generated by greywater sources is less of a concern in sub-surface systems than in above-ground systems.
