Wastewater projects

Significant projects are undertaken by the Council to provide for growth, to upgrade wastewater treatment plants and to reduce wastewater overflows to waterways.

These major projects include upgrades and additions to the Council's wastewater reticulation and treatment plants as part of the Council's Long Term Plan (LTP).
