Sewer Mains and Sewerage Services

Customer Service Standards

Every two years, Council adopts Customer Service Standards for Sewerage Services. These define the level of service Council aims to supply to its sewerage customers. The Water Supply and Sewerage Customer Service Plan 2022/2023 & 2023/2024 (PDF 4.6MB) was adopted at the November 2022 Council meeting.

Depending on where you live, there may be differences in the level of service. This is because Council has adopted different Customer Service Levels within the Local Government area.

Council's pricing policy is based on the NSW Government best practice principals and complies with State Plan NSW 2021.  Best practice sewerage pricing involves a uniform annual sewerage bill for residential customers.  The uniform bill is based on the estimated volume of sewage discharged from residential customers.

For non-residential customers an appropriate sewer usage charge is required for the estimated volume discharged to the sewerage system, together with an access charge based on the capacity requirements.

Council's  Sewerage Services Pricing Policy fact sheet (PDF 1.3MB) details the annual Access Charges and Usage Charges for residential and non-residential customers.

Keeping Tree Roots out of Sewer Lines

Trees and shrubs have a place in residential areas by creating pleasant environments that provide shade during summer, create colourful landscapes and screen out neighbours. Trees have many environmental benefits by providing habitat for native animals and insects, and also reduce salinity and erosion.       

Drains, sewers and water mains can become disrupted, blocked and damaged, sometimes involving costly repairs and removal, because of tree roots.

Council has produced the following guides to assist residents in choosing appropriate plant species to reduce damage and blockages to nearby pipes and structures.

Pressure Sewerage

In outlying areas Council has adopted pressure sewerage as a means of providing sewerage. In such cases the pressure sewerage system replaces the gravity sewerage network Council would have constructed in the past. Please contact Council to obtain a copy of Council's Pressure Sewerage Systems Policy.

If you are the occupier serviced by a pressure sewerage system you should have a Pressure Sewerage Manual  (PDF 897.9KB)
