As Sydney's population grows, our water and wastewater services continue to evolve. We're still investing in major infrastructure, but we're also working with the NSW Government and other agencies to plan more vibrant urban communities and helping developers make these a reality. We're supporting the NSW Government's vision of 3 sustainable, productive and liveable cities – the Western Parkland City, the Central River City and the Eastern Harbour City – and incorporating the coastline city in the Illawarra.
We're moving beyond traditional water servicing to consider alternative water servicing pathways and ways o provide more parks, trees and water bodies. We're looking for more opportunities for recycling and reuse as we enable a transition to water resilience, with less dependance on rainfall.
By 2056, we’ll be providing water services to about eight million customers. We see our role going beyond our current high-quality water and wastewater services, with water playing a lead role in cooling and greening the city.

We plan delivery of our trunk services to align with the their land release program, but we also consider other factors.
Building infrastructure is expensive so the timing of construction is important. Developments must be ready to connect to infrastructure soon after construction to be an efficent and economical investment. And for large areas, we often need to stage water and wastewater infrastructure to account for changes like
From time to time, we may need to acquire privately owned land or establish an easement to build or upgrade infrastructure. Read ourfact sheet to learn more.
When we're building wastewater infrastructure we need to create maintenance holes, so that we can access the network and build vent shafts toallow air to move through the system. Sometimes these are on privte land. Read more aboutand .

Sydney's North West is growing, with half a million people expected to live and work in the area by 2040. To ensure we're ready to meet future demand, we've started the $450 million Lower South Creek Treatment Program (LSCTP). This is one of the largest wastewater programs in the country, which includes:
Delivered by a joint venture between UGL Limited and WSP, the Lower South Creek Treatment Program introduces new leading edge wastewater technology that delivers significant sustainability benefits. The Infrastructure Sustainability Council of Australia (ISCA) has given the program the highest ever rating for an Australian water infrastructure project.
The program is set to achieve a 42% reduction in whole of life greenhouse gas emissions which earned an Infrastructure Sustainability (IS) Design 'Excellent' rating of 69.7 points using innovative processes and technologies such as the transfer of sludge for consolidated biosolids processing and installation of mechanical primary sedimentation screens, which were Australian firsts.
The program's innovative wastewater technologies include:
The Riverstone Wastewater Treatment Plant Upgrade became operational in January 2019, and can serve up to 90,000 new residents. Work is now progressing at our Quakers Hill and St Marys sites. We expect the work to be completed by the end of 2022, weather permitting.

Theis made up of 16 precincts that will accommodate about 33,000 new homes over the next 10 years. Due to the size of the area, we'll deliver the infrastructure in stages.
We'll deliver infrastructure to meet development timeframes. We work closely with other agencies including councils and the Growth Servicing Plan to see timeframes for infrastructure development.to ensure we're servicing the right areas at the right times. See our
We'll continue to consult with affected stakeholders throughout the planning, design and construction process. This includes government agencies, land owners, developers and the wider community.
Upgrades to the existing wastewater network are needed in parts of Liverpool CBD to service new high density developments. We're delivering these services as a priority to meet specific development timeframes.
Liverpool CBD is 28 kilometres west of Sydney on the western bank of the Georges River. Although development is well progressed in Liverpool, there are major high-rise developments proposed along Castlereagh Street, Macquarie Street and Copeland Street, which would have exceeded the capacity of our existing wastewater infrastructure. So we've prioritised servicing this area to meet the development timeframes.
Work should be completed in 2022.
The South West Growth Area is made up of 18 precincts across 17,000 hectares south of Elizabeth Drive to Oran Park. It includes both Camden and Liverpool Local Government Areas. Due to the size of the area and the amount of work, we'll deliver the required infrastructure in stages.
We're building new drinking water and wastewater infrastructure to service about 200,000 new homes over the next 10 years.
We'll deliver the infrastructure to meet development timeframes. We work closely with other agencies including council and theto ensure we're servicing the right areas at the right time.
As work started in 2015 and will continue to 2030, many things could influence timing. Factors that affect the staging of the water and wastewater in the area include:
Austral and Leppington wastewater – Stages 1 and 2
Denham Court wastewater carrier
Oran Park wastewater – Stage 1
SWGA 2nd release water
Leppington reservoir water
We're planning new drinking water, wastewater and recycled water services for about 15,000 new homes in Wilton, in the Wollondilly Shire. We'll be delivering infrastructure in stages until 2025 to service growth demand.
We've been investigating water management system options to accommodate the expected growth and meet projected demands for water-related services to 2046.
The development of Wilton will require significant water-related infrastructure such as new reservoirs, trunk mains, pumping stations and treatment facilities. This infrastructure and the timing of delivery depends on development uptake. Our delivery will be staged to match development demand.
The West Dapto Urban Release Area and Adjacent Growth Areas are about 15 kilometres south west of Wollongong within Wollongong and Shellharbour City Council areas. Covering about 550 hectares, the area will need new water and wastewater infrastructure for about 30,000 homes and non-residential development by 2048. Due to timeframes and the size of the area, we'll be delivering the infrastructure in stages.
Areas covered include Avondale, Cleveland, Kembla Grange, Sheaffes/Wongawilli, West Horsley, and Yallah/Marshall Mount. Adjacent areas Calderwood, Huntley, Tullimbar and Tallawarra.
We worked closely with many stakeholders while developing our plan, including:
