The Darwin Region Water Supply proposal involves upgrades to existing infrastructure and additional water infrastructure.
There are two key components of the proposal :
- Returning Manton Dam to service – increasing water supply for the short term (from 2025-2027).
- The Adelaide River Off-stream Water Storage (AROWS) scheme – increasing medium to long term water supply
The proposal aligns with key initiatives identified within the Darwin Region Water Supply Strategy, which details the Northern Territory Government’s plan to balance demand for water with supply capacity over time.
The proposal also aligns with a range of other state and commonwealth government strategies, policies and priorities.
The proposal is expected to deliver benefits to a range of users by providing improved access to a secure water supply, including industrial, agricultural and urban consumers.
The proponent’s stated benefit–cost ratio is 1.04, with a net present value of $44.05 million (7% real discount rate).
