Flood protection

Click here for Flood Scheme PDF mapFlood protection and land drainage are paramount to our role in keeping people safe and are a major part of our business. Managing rivers through engineering works allows us to help prevent floods and provide adequate land drainage when necessary.

We manage 30 river and drainage schemes across our Region, and maintain over 460 km of stopbanks, 700 km of drains, 20 pumping stations and 53 dams.

This protection is funded through scheme rates based on the amount of protection benefit each ratepayer receives.

If a landowner is not in a designated scheme, Horizons can assist with environmental grants to complete relevant river engineering works.

To ensure people's needs are met we take many things into consideration including type of use, level of flood protection needed, erosion control, disposal of waste products, native habitat protection, recreation, and spiritual values.

River control involves some technical terms that people may not be familiar with. We have included a glossary to help people understand more about flood protection and drainage.

Part of our flood protection is to monitor river heights and rainfall levels so that we can adequately protect our communities. This is done through our Waterline automated warning system and our River Heights and Rainfall service.

Our Waterline warning system is a 24-hour, freephone service which provides river height and rainfall information.

Using our Waterline brochures you can find out how to dial various sites to obtain updates on river height at any time - including during periods of heavy rainfall.
