The scheme assets are owned by the Water Administration Ministerial Corporation and are managed under delegation by the Office of Environment and Heritage (OEH). Scheme assets are located on private land.
Hunter Local Land Services' share is funded by the Hunter Catchment Contributions. Local government ratepayers in the Hunter catchment pay an annual levy, known as Hunter catchment contributions. Local councils also provide a small contribution. Chapter 5 Public Works – Part 2 of the Water Management Act refers directly to Hunter Valley Flood Mitigation works. Works are approved under Part 5 of the Environment Planning and Assessment Act 1979.
OEH is responsible for all maintenance activities of scheme assets. Maintenance activities include:
- levee mowing
- spraying of aquatic and terrestrial weeds
- cleaning of drains
- floodgate repairs.
In some cases, drainage channels extend beyond OEH's jurisdiction and OEH has no authority to undertake any works in these areas.
OEH also contracts other agencies and organisations to do work on their behalf. This can include project design and management, construction work, assessment of environmental factors and stakeholder engagement.
