Northern Adelaide Irrigation Scheme (NAIS)

A key priority of the Northern Adelaide Plains Agribusiness Initiative is to achieve growth in agricultural industries through increased access to water resources.

The South Australian Government is acting to grow the capacity of the Northern Adelaide Plains region to ensure the long-term viability of its horticulture industry and the social and economic future of its communities.

Through the Northern Adelaide Irrigation Scheme (NAIS), the government is proposing to help secure large volumes of affordable, high security, recycled water for the region.

An additional 12 gigalitres (GL) per year of recycled water suitable for irrigation would be sourced from the Bolivar Waste Water Treatment Plant, increasing the reuse of treated water from this site by 60 per cent.

The South Australian Government has applied to the Australian Government's National Water Infrastructure Development Fund (NWIDF) for $45.6 million in funding to construct the infrastructure for the NAIS.

A decision on the NWIDF funding is expected to be announced in mid-2017. If NWIDF funding is approved, the State Government, through SA Water, will co-invest $110 million in the NAIS project.

A combined investment of $155.6 million would be used to:

  • upgrade infrastructure at the Bolivar Waste Water Treatment Plant to produce an additional 12 GL per year of recycled water suitable for irrigation
  • build core recycled water distribution infrastructure to the area north of the Gawler River
  • enable a major new irrigation area to be constructed, including high-tech, high-value intensive food production.

This would transform the region into the national leader in intensive, high-tech food production, support existing industry to expand and become more competitive, as well as drive employment growth and attract new skills and talent into South Australia.
