If you live in a un-sewered area, you must have an EPA approved wastewater treatment system which is capable of treating the wastes produced from your house within the boundary of your premise.
How you treat the wastewater will depend on your site conditions and personal choice. Onsite wastewater is divided into five categories:
- Sewage: All wastewater
- Greywater: Water from the shower, bath, basins, washing machine, laundry trough and kitchen (also referred to as sullage).
- Blackwater: Toilet waste
- Yellowwater: Urine with or without water
- Brownwater: Sewage without urine
