Sewage pipeline to cause disruption

Disruptions are unavoidable as construction of a new sewage pipeline enters Waitara's urban area, the New Plymouth District Council says.

Work on the Waitara to New Plymouth pipeline is currently taking place on the section of Brown Rd from Tate Rd to Te Rangitahi Heritage Walkway, formerly known as the Waitara West Walkway.

The pipeline's installation on the walkway itself is due to start on October 19, and will then take place on Norman St, Broadway, High St West and across Queen St to the Waitara wastewater treatment plant.

Some properties along the pipeline's route may have no vehicle access for up to four days, but foot access will remain at all times.

Roads and intersections will be either closed or down to one lane during the installation.

“Unfortunately there will be a lot of disruption for residents along the pipeline's route," NPDC operations manager Graeme Pool said.

"We'll try to minimise this as much as we possibly can but it's important that people are aware of the impact the work will have.”

The council is organising letter drops and door-knocks along the route and there will be an information display at the Waitara Library and Service Centre.

"We'll also have the latest information on the project's schedule on our website at newplymouthnz.com/WaitaraPipeline - we encourage people to check that webpage regularly during the construction period,” Mr Pool said.

However, those affected should bear in mind Wills Rd residents, near Bell Block, had to endure waits as long as 40 minutes and had no communication about the work when the pipeline was laid through their patch.

Work would take place from 7am to 7pm from Monday to Saturday and would be noisy. There would be no work outside those hours unless it was an emergency, he said.

Vehicle access could be blocked for up to four days to each property on the side of the road where the pipeline was being laid and residents would only be able to get into their homes by foot.

“We encourage residents to consider where they'll park their cars during that period,” Mr Pool said.

Residents would see pipes being stacked on nearby sections or grass berms before being laid in 90m to 100m sections.

“One day before the pipeline trench is dug, topsoil will be stripped to check for items of archaeological interest under the supervision of a cultural monitor from Otaraoa hapu," he said.

Once the pipe is laid, the trench will be backfilled and the next section will have the topsoil stripped.

“This entire process may take up to four days depending on weather conditions, ground conditions and the number of underground services encountered.”

Full reinstatement of roads and entranceways could take up to two weeks and the full reinstatement of grass berms up to four weeks.

Excavations at air valve chambers and certain welds may remain open for up to four weeks until testing of the pipeline is completed. These excavations will be fenced off and made secure.

The installation is due for completion by Christmas.

Should New Plymouth switch to energy-saving streetlights?

No. They're a nice-to-have and too expensive to implement right now.
