Wastewater treatment approval process

There are various wastewater systems that you can install on your property, however each and every arrangement has a range of approvals to be obtained before they can be installed. This is to ensure that you, your household, your neighbours and the environment will not be negatively impacted by the system, which can have a huge range of issues if it isn't the correct system for your needs.
