About the program

We're currently in the planning or construction stage for a number of projects that will help fix wastewater surcharges at private properties in Sydney.

This work is part of our SewerFix Program to improve the wastewater system and protect public health and the environment.

When it rains, rainwater enters the wastewater system causing the pipes to fill to capacity.  In some areas, the pipes overflow onto private properties when they reach capacity.

The Internal Surcharge Improvement Program addresses this problem.
