Tenders have been called for the construction of the 12.5km-long sewer pipeline from Waitara to New Plymouth.
Manager Projects Mark Hall says the pipeline will run from the Waitara Wastewater Treatment Plant in Queen Street to the New Plymouth WWTP in Waiwhakaiho.
“We are running the pipeline construction as two separate contracts: The first is the rising or pressure main from Waitara to a high point near The Links, and the second is the falling or gravity main from The Links to Waiwhakaiho,” says Mr Hall.
“We expect construction to start in October.”
Registrations of interest have already been received on the upgrade of the New Plymouth WWTP, and three companies have been invited to tender for this specialist job. Construction at the plant will begin in the New Year.
Once the Waitara to New Plymouth pipeline is completed, tenders will be called for the conversion of the Waitara WWTP into a pump station.
The entire project is expected to be completed by the end of 2013, after which Waitara’s wastewater will be treated at the New Plymouth’s upgraded plant.
