Canterbury/Waitaha has substantial water resources. They include surface waterbodies, groundwater systems, and an extensive coastal marine area.

Water quantity refers to the hydrological system of Waitaha and includes precipitation (rain and snow) and its effects on flows and water levels of our rivers, lakes, wetlands, aquifers and the interaction with marine waters. 

Water quality variability is strongly linked to, and driven by the hydrological and climatic regime.  For example, river flow is hugely influential on aquatic ecosystems (e.g. rivers and wetlands) and coastal environments (e.g. estuaries and hapūa) because it facilitates and regulates many processes.  

Here we look at the water quantity and quality issues facing our region that inform our planning framework.
