Construction of East Rotoiti | Rotomā Sewerage scheme is underway

09 October 2018 - Progress on building a sewerage scheme for the east Rotoiti and Rotomā communities is on track.

Construction of a Wastewater Treatment Plant behind the Emery Store in Rotoiti and a road to the plant is underway.

Contractors have also laid about 13km of the 22km reticulation line starting from Matahī Road and, will in time, be connected to the plant.


The aim is to initially connect Rotomā properties including non-residential to the new service by April next year, via on-property Septic Tank Effluent Pumping systems - known as STEP.

The on-site pre-treatment devices will be hooked up to the reticulation network which will be connected to the Wastewater Treatment Plant.

As of the first week of October, 114 of the total 212 consents to install the STEP system in Rotomā have been signed and received by Rotorua Lakes Council.

Its General Manager of Infrastructure, Stavros Michael, reported this to elected members last week.

A decision for a pre-treatment effluent system for Rotoiti homes hasn’t been made yet.

Last year, a system called Biolytix was trialled.

Mr Michael told elected members at last week’s Operations and Monitoring Committee meeting that Council is looking for a supplier which will provide the most cost effective system for the community.

He says a device that also complies to the needs of resource consent for Rotoiti.

A request for tender process is being prepared to determine whether Biolytix or the alternative, STEP system, should be adopted for the community.

Council aims to find a supplier which will install the preferred pre-treatment system that runs it for 15 years.

Mr Michael says that it will make a decision based on objectives such as:

· Providing an essential service for the community

· Helps protect the mauri (life force) of the lake and the health of the people; as well as

· Providing a service in a way that is culturally appropriate
