Water supply

Christchurch drinking water is mainly drawn from aquifers deep underground. The Council has a network of wells, reservoirs, pipes and pump stations. It does regular testing and maintenance in line with the Drinking Water Standards for New Zealand(external link).

Water chlorination

Water chlorination is the process of adding chlorine to the water supply to keep it safe from harmful bacteria. Sodium Hypochlorite is used in Christchurch.
