Hygiene Practices to Prevent Water Supply Contamination

Ensuring good industry practice when staff or contractors are working on water supply systems is an essential element of protecting the public from possible infection. At present in New Zealand, there is a range of guidance material used, with some sourced from overseas.

This guide was produced at the request of water service managers employed by local authorities, to provide advice based on best practice overseas and in New Zealand.

Water New Zealand encourages councils operating public water supplies to adopt this document, and to ensure staff and contractors working on their systems adopt the practices it contains.
