River & Drainage Schemes

The river management team at Horizons is responsible for maintaining the river and drainage systems in the region to minimise erosion and ensure optimum flood protection for our communities. With many urban communities located on flood plains, it is important to have an appropriate standard of flood risk mitigation for the safety of the community. The protection of the flood plains is also important for protecting productive land, which is important to the economic goals of the immediately affected areas as well as the wider region.

Flood protection is funded through general and Scheme rates based on the amount of protection benefit each ratepayer receives. Horizons currently manages 34 River and Drainage Schemes across our region, maintains over 490 km of stopbanks, 1090 km of drains, 23 pumping stations and 53 dams.
