The On-Site Effluent Treatment Regional Plan 2006 (OSET Plan) directs the management of domestic wastewater to protect water quality in the Bay of Plenty. On-site effluent treatment systems include septic tanks and associated soakage fields and advanced aerobic systems.

NOTE: Draft Plan Change 14 (OSET) to the Regional Natural Resources Plan will eventually replace the On-Site Effluent Treatment Regional Plan.

Reticulation

In many parts of the Bay of Plenty, communities have been provided with sewers or reticulated wastewater systems. Where a sewer is available, then you must connect. This is subject to the provisions of the Local Government Act 1974 section 459. Your District Council or City Council should be able to advise you if your area has been or is scheduled for reticulation.

There are maps of some areas where reticulation has been provided in the OSET Plan.

Western Bay of Plenty District Council has proposed a reticulation scheme for the Te Puna West Maintenance Zone. Find out more.

OSET system design training

On-site effluent treatment systems must be designed by a Suitably Qualified and Experienced Person (SQEP). To ensure the wastewater system is properly designed, we have developed a training course for system designers. 

The OSET system training course incorporates the following unit standards.

We have contracted Opus Environmental Training Centre to deliver this course.  You can register your interest by visiting their website.

Choose Wastewater and then scroll down to Onsite Wastewater Training. The first half of this course will be delivered during late March 2014.  Some designers may already be qualified to undertake this work. If you think you are already qualified and want to use the “Recognition of Prior Learning RPL” process, contact NZWeta on the website above.
