Waiāri Water Supply Scheme pipeline route decided

Tauranga City Council’s third water treatment plant has reached a major milestone with the finalising of the underground pipeline route.

The Waiāri Water Supply Scheme pipeline will start at 376 No. 1 Road, Te Puke, run down No. 1 Road through Lawrence Oliver Park, across private property and out to the Poplar Lane reservoir.

Underground pipes from there will carry the water along the Te Puke highway and Welcome Bay Road to the eastern reservoir at R942.

Tauranga City Council Environment Committee Chair Steve Morris said the route was designed to minimise disruption to Te Puke locals and ensure the best value for money for Tauranga ratepayers.

“Our engineers and consultants considered many factors when coming up with the best way to deliver water from the new treatment plant to people’s properties,” Mr Morris said.

“We’ve done our best to minimise the disruption to Te Puke residents and businesses, avoiding where we can major thoroughfares and commercial areas.

“We’ll also be avoiding work on No. 1 Road during kiwifruit-picking season, to minimise disruption to local industries and residents already affected by traffic disruptions during these busy times.”

Mr Morris added the 22-kilometre network of pipes would be located to avoid existing infrastructure as much as possible.

The pipeline works were expected to start in January 2019 and be completed by August 2021.

Mr Morris said significant safety measures were in place to protect the Waiāri Stream during the construction.

“Protecting the stream from environmental impacts has always been paramount to this project’s success,” Mr Morris said.

“We’ll also have cultural and earthworks monitors in place when earthworks are undertaken to protect cultural sites of significance, taonga and waahi tapu.

“Elected Members marked the start of the works with a blessing led by Pouroto Ngaropo of Tapuika in March this year, and this blessing really brought home the stream’s spiritual significance and the inherent relationship tangata whenua have with the waterway.

“We’ll be recognising this cultural significance by developing Mauri monitoring tools to put in place before any water is abstracted from the stream.”

In March this year, works commenced to build access routes and a stream bridge for use during the scheme’s construction.

The access route leads from Te Matai Road across the stream with a connection to No. 1 Road, allowing access to the construction site.

Once the access routes are in place, works on the abstraction facility will start this summer.

The Waiāri Water Supply Scheme involves developing a new water abstraction facility on the Waiāri Stream, a water treatment plant in No.1 Road, Te Puke, and an underground water pipeline from the plant to Poplar Lane, Eastern Reservoir and Papamoa.

The plant will mainly service the Papamoa coastal strip and the Te Tumu growth area, and may in the future provide a backup for Western Bay of Plenty District Council’s Te Puke water supply.

The scheme is expected to be completed in 2021.
