Understand the strategy landscape

NSW’s metropolitan and regional water strategies provide different geographic planning contexts. Use the current strategy for the study area and distinguish a long-term strategic option from a funded or commissioned project. Publication of an option does not establish its delivery status.

Portfolio planning

Compare conservation, operational improvements and additional sources against a consistent service objective. Desalination, recycling, groundwater and transfers have different dependencies. Examine energy, source quality, environmental impacts, treatment barriers and network integration.

Regional constraints

For river-dependent towns, low flows and water quality may constrain supply before a nominal storage volume is exhausted. For groundwater-dependent systems, sustainable extraction and aquifer response require their own assessment. Do not assume a metropolitan solution scales directly to a small community.

People, Country and evidence

Water planning affects cultural, social and ecological outcomes. The NSW Aboriginal Water Strategy is a primary reference for the state’s approach; local engagement is still essential. Combine that context with a transparent system water balance and scenario testing.
