The Department of Planning, Industry and Environment (DPIE) is responsible for developing strategic plans which integrate land use and infrastructure planning. It also delivers planning and infrastructure programs for housing and jobs both in new land release areas and urban renewal precincts. This includes developing zoning and development controls through Local Environmental Plans (LEPs) to guide planning decisions locally.

DPIE’s Water Group leads and coordinates metropolitan water planning for Greater Sydney. They are not represented at the symposium as they are currently finalising the Draft Greater Sydney Water Strategy for public consultation. WaterNSW manages the that collect rainwater run-off from catchments to the south and west of Sydney. The water is stored and transported via a network of , pipes and canals to Sydney Water. WaterNSW is also responsible for protecting the health of Greater Sydney’s drinking water catchments.

Sydney Water operates the nine water filtration plants that treat the raw water provided by WaterNSW, and delivers the treated drinking water to customers in the Greater Sydney, Blue Mountains and . Sydney Water also collects and treats wastewater, provides recycled water services to some areas and manages some major stormwater infrastructure. Sydney Water is also responsible for water supply planning in line with numerous drivers, such as growth, climate change and environmental performance.

Note: Private water utilities licensed under the Water Industry Competition Act 2006 provide water services to a number of communities in Greater Sydney, often using supply solutions that include recycled water. 5 How is Sydney Water working to provide a secure water supply for the growing Wollondilly region?

Reimagining Water in Western Sydney

• Western Sydney is critical to Sydney’s future growth and prosperity. • It is ’s third largest economy and home to over 1 million people. • Western Sydney is forecast to accommodate 800,000 new residents by 2036. • It has some of the cities most sensitive waterways • The emerging Parkland City will require our relationship with water to change The vision for Western Sydney is: Our customers enjoy and afford essential water services, healthy waterways and vibrant green spaces.

11 Our plan for a circular economy Lessons learned from drought

• Plan for drought before the next drought starts and consider worst case scenarios, even though they are unlikely • Recognise that some parts of the system will deplete faster than others • Increase the diversity of water supply sources, including more rainfall-independent supply • Have options at-the-ready to respond quickly when drought conditions return • Have an adaptive approach that gives us the flexibility to adjust our policies, plans and investment decisions as circumstances change — including changes to the climate, rates of population growth and where and how people choose to live and work.

13 Greater Sydney Water Strategy

• Sydney's experience with severe drought and rain shows how quickly our water supply can deplete and replenish. The Greater Sydney Water Strategy will help us respond and adapt quickly so that we have a secure, integrated water supply for the future. • Sydney Water is working together with the Department of Planning, Industry and Environment and Water NSW, to deliver an integrated, innovative and cost-effective plan. • It is also keen to partner with other agencies, including local government, to make sure the views of all our communities and stakeholders are considered. • Community will have an opportunity to provide feedback on the strategy in future. • The Greater Sydney Water Strategy is considering  All options for augmenting water supply, including rainfall independent sources.  Nodal Risks and System Interconnections  Water Conservation and Demand Management  Waterways Values and the Environment  Integrated Water Cycle Management Approaches

18 Water supply planning – the past does not reflect the future

Greater Sydney experienced one of the worst drought sequences on record between mid-2017 and early 2020.

• record low inflows • unprecedented storage depletion rates

Total storage reduced by over 50% in 2.5 years Redundancy concepts Each concept below can provide a mix of benefits for delivering reliable water products By creating redundancy in our delivery systems, Sydney can leverage supply and configuration options and resistance to threats. For any given to achieve a more resilient system overall. To produce the map below, we canvassed a range of combination of concepts, what resilience experts from across strategy, planning, and operations in Sydney Water and WaterNSW to identify benefits will that provide, and at what cost? options for making our overall water system more resilient (see dotted lines in Figure 11 below).

Welcome Reef Head of City Growth and Development Chris Gantt Supporting growth

We plan our delivery of services to align with the NSW Government’s land release program. Our main guide is the DPIE dwelling projection forecast, but we also consider:

• NSW Government benchmarks for zoned and serviced land

• Sub-regional analysis of greenfield areas

• Development application activities and dwelling completions

• Comparison of annual completion rates to the corresponding dwelling production forecasts

• Capacity of existing infrastructure
