Pātai Putuputu FAQs
The Committee identified and considered five possible and viable wastewater options:
A Septic Tank Effluent Pump (STEP) system located on your property. A STEP system is a 3800 litre septic tank with a filter and pump inside the tank. The filtered effluent is pumped through pressure pipes to a local Wastewater Treatment Plant and the solids remain in the system, which have to be removed periodically.
A STEP system where the filtered effluent is pumped to Ōkāreka and on to the Rotorua Wastewater Treatment Plant.
A Low Pressure Grinder Pump (LPGP) would be located on your property to pump all the waste to a local Wastewater Treatment Plant.
A Low Pressure Grinder Pump that pumps the waste to Ōkāreka and then on to the Rotorua Wastewater Treatment Plant.
If no decision is made to have a community reticulation system, then each individual property owner will need to: Install an Aerated Wastewater Treatment System with Nutrient Reducing capabilities (AWTS+NR), which is also referred to as OSET (Onsite Effluent Treatment) system. The wastewater from this system would be discharged to a soil soakage system. This system would be an improvement in performance over septic tanks but would not fully remove the N and P from the catchment. It would also require a reasonable amount of land for disposal of the effluent.
*Option 5 was the least preferred option. It was not eligible for subsidy and not all properties would be able to accommodate one of these systems because of land slope and stability, available space, proximity to ground water and unsuitable soils. Property owners in this category would need to apply for a resource consent which would seek to mitigate the effects of the discharge.
The committee determined that option 4 appeared to best meet the objectives of being more environmentally friendly and affordable.
A Cultural Impact Assessment was undertaken by iwi to confirm that this option (Option 4) met cultural aspirations.
