Background to the Project

• In 2017 the Bay of Plenty Regional Council proposed a change to the Regional Plan that manages on-site effluent treatment systems Bay of Plenty region.
• Under “Plan Change 14” the installation of new septic tanks in the Tarawera area is prohibited and consents for existing septic tanks will not be renewed.
• The Tarawera Ratepayers Association asked Rotorua Lakes Council to assist them in finding a workable solution.
• Several options for sewage management were investigated and a Low Pressure Grinder Pump (LPGP) scheme was subsequently selected as the most suitable.
• Concept design studies were subsequently carried out to obtain early estimates of cost.
• On 28th June 2021 Rotorua Lakes Council adopted the design and delivery of a reticulated sewerage scheme for Tarawera and approved work to progress the detailed design of the scheme. This would enable a more accurate construction cost to be defined which will determine the ‘contribution’ that would be paid by residents for construction of the scheme.
• In November 2021 Rotorua Lakes Council engaged TRILITY to complete the detailed design of the LPGP scheme.
• The visual survey of each property will allow TRILITY to accurately work out the LPGP requirements for each.
• In order to meet funding deadlines TRILITY need to complete the design by the end of March 2022.

Frequently Asked Questions

I maintain my septic tank and it is in good order. Can I continue to use it?

No. Under Plan Change 14 Rotorua Regional Council will no longer issue new consents for septic tank systems or renew consents for existing septic tanks. The Local Government Act requires that properties connect to a reticulated wastewater system if one is provided.

I have an Aerated Waste Treatment System (AWTS or AWTS+NR) on my property. Can I continue to use it?

No. The Local Government Act requires that properties connect to a reticulated wastewater system if one is provided.

How many dwellings on a single property can be connected to a single LPGP system?

A separate LPGP unit will be required for each household / dwelling on each property. An out-building (such as a granny flat or sleep-out) can discharge waste water into the LPGP of the dwelling it belongs to if it is practicable to do so. Larger dwellings, or dwellings with more than one household within them may be required to install a larger capacity ‘Duplex’ or ‘Quadplex’ LPGP unit.

Who maintains the LPGP scheme once it’s installed?

Rotorua Lakes Council will service and repair the pressure sewerage installation on your Property and in the street. The Council is not responsible for the household plumbing that drains to the storage tank. Repairs to the property owner’s plumbing system (up to the connection to the LPGP storage tank) are at the owner’s expense, as are repairs for any other form of sewerage system.

What can I flush and what can’t I flush?

You should use the toilet in the same way as you do for a septic tank or AWTS system. No nappies, sanitary napkins, tampons or wet wipes (including those that are marked as flushable) can be flushed through the LPGP system.

What do I do if there’s a fault with my LPGP?

Rotorua Lakes Council can be called 24 hours for assistance. The operator will help you to resolve simple issues over the phone, and dispatch a contractor to your home if required. If the LPGP unit detects a fault, a red warning light will illuminate on the unit’s control box. The user instructions provided with the unit will describe what to do when this happens.

I use my property infrequently. What should I know?

If your property is to be left unused for a significant period of time, the only thing you need to do is to flush water through the system to make sure that the pipe from your house to the street is clear of waste. Instructions on how to do this are provided with the unit.

I let my property (long term rental or short term holiday let). What should I know?

You must make sure that clear instructions are left so that non-flushable items are not flushed into the system by your tenants. Signs and stickers will be available from Rotorua Lakes Council if you wish to display a warning adjacent to each sanitary fitting.

I am planning to build a new dwelling within my property or subdivide while the scheme is being designed and constructed. What must I do?

Discharge to land falls within the Bay Of Plenty Regional Council jurisdiction. It may be possible to install an interim wastewater system until the LPGP installation for the property is installed. Please contact Monique Ullyett at the BOP Regional Council to discuss your plans.

What will I pay?

The scheme is partially funded by the Ministry for the Environment, Rotorua Lakes Council and Bay of Plenty Regional Council. The rest of the cost will be met by contributions from each property that will benefit from the scheme.

The financial contribution is broken down into 2 parts:
• Part 1: A share of the cost of installing the Tarawera network
• Part 2: The cost for installing the LPGP systems onto each property

The current design work being undertaken by TRILITY will determine the construction costs for each Part. Each property benefiting from the scheme will pay an equal share of the Part 1 and Part 2 contribution.

Properties with existing dwellings will pay both Part 1 and Part 2 contributions.

Undeveloped sections will pay Part 1 only. This would cover the section’s contribution to the cost of the network construction and would leave a connection point in the street pipe for any future installation. Part 2 would only become payable when the section is developed and an LPGP pump is connected to the network. The Part 2 amount to be paid at the time of development may be influenced by the cost of installation (construction market rates etc.) at the time it is done.

How will I pay?

Payment options are currently being discussed through the Tarawera Wastewater Reticulation Funding Working Group (which includes representatives from the Tarawera community and Ratepayers). More information on payment options will be available in the near future.

Will the pipeline along Spencer Road be trenched or thrust?

This will be determined following completion of the detailed design process. Different installation methods may be required depending on the location and design requirements of the section of pipe being installed.
