Servicing frequencies for your pre-treatment device are specified in your Trade Waste Approval. Frequencies vary according to:
- type and size
- type and size of the business discharging to the pre-treatment device
- cooking and cleaning practices used at the business.
As a general guide, the periods between servicing should not be greater than three months.
The business owner is responsible for arranging service and maintenance of their pre-treatment device. Evidence of this service is required by Unitywater in the form of a receipt issued by the private contractor. This information must be in an acceptable format to Unitywater.
