Do you need to alter an onsite wastewater management system? You will need a permit to alter an existing system.
Types of Permit to Alter
A Permit to Alter is required when works are required to repair or upgrade your system. There are two types of alters:
- Major alter: Consists of works that adds to or replaces the tank or effluent field of the system.
- Minor alter: Consists only of the installation, replacement or relocation of the internal plumbing, fixtures or fittings of the OWMS.
