• Drinking-water supply safety

Temporary water supplies and water supplies at events

If you are organising an event for more than 24 people, and intend to offer drinking water that is not commercially bottled, you need to seek permission from the Nelson Marlborough Public Health Service.

You may also be responsible for other suppliers of drinking water at the event.

If the drinking water is not approved (or you have not allowed sufficient time for the approval process) you will have to find an alternative source of approved drinking-water or postpone the event. This may also affect any required alcohol licences because free drinking water is a legal requirement when alcohol is provided at an event.

How to seek permission

contact the Drinking Water Team (DWT) at Nelson Marlborough Health's Public Health Service
ask for a 'WS03 notification form' or download one from the Ministry of Health website
submit your completed form to the DWT at least 14 days (10 working days) prior to the event

Why do you need to seek permission

under the Health (Drinking-Water) Amendment Act (HDWAA) Section 69ZI there is a duty to advise a Medical Officer of Health at your Public Health Service if you intend to supply drinking water at an event for more than 25 persons
this helps protect people from the risks of pathogenic organisms that are commonly found in untreated, unboiled water
should event attendees contract an infection or disease then your notification (and compliance with any set specified conditions) could help your defence by demonstrating due diligence
under Section 69 ZZR (3)(g) a person who fails to advise the Medical Officer of Health may, upon summary conviction, be liable to a fine of up to $5,000.
