Guidelines for Drinking-water Quality Management for New Zealand

Summary

The Guidelines for Drinking-water Quality Management for New Zealand complement the Drinking-water Standards for New Zealand 2005 (revised 2008). The Guidelines explain the development of the Standards and provide advice for achieving high level of water quality management. The Guidelines will help water suppliers to achieve the Standards.

Note: The Guidelines are updated on an ongoing basis. The date on the footer of each chapter or datasheet is an indication of when that section of the Guidelines was last updated. It is recommended that anyone using these Guidelines uses this web version and does not print the Guidelines, as chapters and datasheets may become out of date.
