Backflow Prevention

You could be affected.

Recent events (in Havelock North in particular) have highlighted the need for backflow prevention devices to be more readily enforced. Backflow prevention requirements haven't been enforced for a number of years but are a legal requirement on certain properties identified in the water supply regulations in the Health Act. Is your property compliant?

WHAT IS BACKFLOW?

Backflow can occur from anyone’s water connection when the pressure in their private system exceeds the pressure in the public water supply. This can create a syphon effect that could allow any contaminates present inside the private property to enter the public water supply. Backflow prevention devices are fitted at the property boundary to protect the public water supply from contamination.


Matamata-Piako District Requirements

Information brochures and letters have been issued to those in the Matamata- Piako area that will require a backflow device, in accordance with the Health Act.

Over the next 12 months, all properties that require backflow prevention devices will be required to install a device or air gap separation device at the property boundary. This will then need to be inspected and recertified annually.

The council is enforcing deadlines for these installations based on priority with the soonest happening on 31 December 2018.

Properties that require Backflow Prevention devices


High riskIncludes operations in urban/industrial areas – e.g. chemical plants, sites using, processing or manufacturing toxic materials, hospitals, rest homes, medical and dental centres, vets, funeral directors, truck washing, butchers’ shops, and commercial laundries.

Operations in rural areas such as farms and equine establishments.

Connections on the trunk mains connecting water sources to the towns in Matamata, Morrinsville and Te Aroha are regarded as a high risk due to the number of persons who could be potentially affected.
Medium riskRisks in rural/urban areas – e.g. lifestyle blocks under 2 ha where stock is grazed, hairdressers and car washing facilities.
Low riskProcesses on the property have the potential to discolour water or change water taste or odour but do not endanger health.

Examples include hose taps for domestic irrigation systems and hose taps used for filling swimming pools and spa pools.
