Water is life-supporting and is essential to Christchurch's cultural, social, economic and environmental well-being.
The purity of Christchurch's groundwater is an important asset and a great source of pride for Christchurch residents. Purified naturally in underground aquifers by filtering through layers of gravel, it is one of the highest quality natural water supplies of any city in the world. Our coastal, lake and river waters are a focal point for recreational activities and have major cultural, economic and environmental significance. It is therefore essential that domestic, industrial and agricultural overuse and misuse of water is minimised to ensure the quality and quantity of all water within Christchurch is maintained.
