Projects to maintain and upgrade our wastewater system are an important part of what we do to help protect public health and the environment across Sydney, the Blue Mountains and the Illawarra. Whether it's our pipes, wastewater overflows, pumping stations or treatment and recycling plants, we're committed to making the system better.
We improve the reliability of our wastewater system by repairing or replacing old wastewater pipes. We also install new pipes to increase the system’s capacity.
We repair or replace small sections of cracked, collapsed or damaged wastewater pipes across our system throughout Sydney. Thousands of jobs are completed each year as part of our Network Repairs Program.
We’re investigating options to deliver a permanent long-term solution to manage the last remaining untreated wastewater ocean outfalls in NSW. See what we're doing at Vaucluse and Diamond Bay in Sydney.
We're upgrading lengths of our wastewater and stormwater pipes throughout Sydney. This work helps prevent leaks in pipes for the next 50 years.

Specialist crews usually need to make several visits to affected properties. Each project takes about 4 weeks to complete.
This work is part of our SewerFix Program to:
When the wastewater system is blocked or reaches capacity in heavy wet weather, wastewater can overflow to the local environment or within private properties. Our work includes removing blockages from pipes and building infrastructure or installing new pipes to store excess wastewater flows when needed. This helps to:
Our Internal Surcharge Improvement Program is helping us fix wastewater (sewage) surcharges at private properties.

Wastewater pumping stations move wastewater flows uphill, where gravity is not effective in transporting wastewater through the system.
We build, modify or repair our wastewater pumping stations to help the wastewater system operate efficiently.
Wastewater from homes, businesses and industry is treated to a high level at our wastewater treatment and water recycling plants.
Our wastewater treatment plant improvement program helps increase our plants' performance and reliability. This includes minimising odours and expanding the capacity of our treatment plants to service the growing population.
We're upgrading our Picton Water Recycling Plant to service new connections and growth in the area.
We're also improving the odour management system at our North Head Wastewater Treatment Plant.
We're working at Malabar Wastewater Treatment Plant to:
Our work to improve existing infrastructure above and below ground at the plant includes replacing or upgrading the:
We'll also remove equipment that's no longer required and landscape the site.
This work is being delivered by 4Malabar, an alliance between Sydney Water, John Holland, UGL Engineering and GHD.
