What is the Waiari Water Supply Project?
A new water processing plant is planned to meet Tauranga’s needs as a growing city.
The Waiari Water Supply Project is designed to help meet the future water supply needs of Tauranga City and Western Bay of Plenty.
The project involves the development of a new water supply intake from the Waiari Stream, a water processing plant in No.1 Road, Te Puke and a water pipeline from the plant to Papamoa.
Why is a New Water Supply Needed?
Existing Water Abstraction Consent
Tauranga City Council (TCC) and Western Bay of Plenty District Council (WBOPDC) currently share a resource consent to abstract ((take) up to 60,000m3/day from the Waiari Stream, located on the southern side of Te Puke. However, at this time no water is being abstracted from the Waiari Stream.
Increased Demand in the Coastal Strip
The coastal strip from Mount Maunganui to Papamoa is Tauranga’s highest predicted growth area over the next 50 years. According to the Smart Growth sub-regional development plan, the Papamoa population itself is expected to increase three fold from the present 12,300 over the next 30 years.
It is expected that the water demand from Mount Maunganui and Papamoa will exceed the supply available from existing water pipelines in the next ten years.
Security of Supply for Western Bay of Plenty
In order to provide a back up water supply to the existing groundwater bores which service the Te Puke area, and also to ensure future increases in water demand can be met, WBOPDC wishes to share 15,000m3/day of the Waiari Stream abstraction consent for the next 50 or more years.
Waiari Water Supply Project Stage 1
In order to address the predicted shortfall in water supply capacity, TCC plans to construct the first stage of the Waiari Water Supply project consisting of a new water intake at the Waiari Stream in No1 Road near Te Puke along with a new water treatment plant, water storage and a new trunk main to deliver the water to the existing infrastructure serving Papamoa. The capacity of the first stage will be 30,000m3/day.
Depending on the rate of population growth and the success of new measures to reduce water use, construction is expected to start around 2018 and be finished around 2021.
