You will need approval if you intend to install an on-site wastewater system. A wastewater management system is a system for the collection and management of wastewater which consists of all greywater or black water, but does not include stormwater or commercial and industrial wastewater.
This approval applies to on-site waste water management systems, including:
- septic tanks
- greywater systems
- composting toilets
- secondary treatment systems
- aerated wastewater treatment systems.
