Watercare hopes to start work next year on a wastewater pipeline from a site just north of the new community transport hub on State Highway 1 to the pump station in Lucy Moore Memorial Park.
Five routes were originally under consideration, but Watercare has discarded the option of a route along the riverfront due to the impact on public space and the susceptibility to river flooding.
While Watercare did not disclose what the other four routes were, it is understood the most favoured route will see it cross the river west of the The Bridgehouse and then come underground down Percy Street, past the supermarket, and through the park.
Head of strategy and planning Priyan Perera says the new pipeline is part of Watercare’s programme of work to cater to growth in Warkworth and the surrounding area, and clean up the Mahurangi River.
“The pipeline will serve the new developments in the north-west of Warkworth and will allow us to eliminate an overflow point that discharges into the Mahurangi River,” he says.
“We have not yet settled on a route for the pipeline and are exploring a number of options and construction methodologies.
“We have been talking with key stakeholders as part of this process and intend to continue these discussions in a transparent manner, so everyone understands how we select a preferred route.
“At this time no decisions have been made and we will continue engaging with the Local Board and key stakeholders as we gather more information.”
Perera says construction is expected to start next year, subject to Watercare obtaining the necessary consents and landowner approvals.
