Mowhanau Village at Kai Iwi Beach is about 16km from central Whanganui.
The city’s wastewater treatment plant is on Airport Rd.
Hooper told the Whanganui Rural Community Board a new pipe would run from Mowhanau along Rapanui, Francis and Tayforth Roads, and join with the reticulation at Springvale Rd, a distance of about 14km.
Piping waste to the city would cost $8.1m over 50 years, while a “like-for-like” local system would cost $13.9m, the report said.
He told the board waste from septic tanks in the village went through sand filter beds - “quite old technology” - and on to an irrigation paddock.
“During summer, we just spray the effluent over the paddock and during winter, when soakage is not so good, there are soak pits which we discharge to.”
It had been planned to install a new pump station opposite the Mowhanau Lookout carpark on Sunset Parade but the community did not want it so close to a popular location, he said.
“We’ve gone back to the designer, looking at where we can relocate it,” he said.
“The first part of the construction will be installing the pipeline and I’m hopeful that by mid-year we’ll be started on that.”
