The Owhango community is set to benefit from the end of
boil water notices with installation of a new state-of-the-art containerised
Water Treatment Plant (WTP). The $4.2 million project will bring safe,
high-quality drinking water to Owhango, fully compliant with the Drinking Water
Quality Assurance Rules.
Executive Manager Infrastructure, Vini Dutra, shared his
enthusiasm for the project, noting the long-standing need for an upgraded
treatment facility. "Council has been wanting to upgrade the Owhango Water
Treatment Plant for some time, and it's very exciting to finally be at this
stage," he said. "This investment ensures a reliable, safe water
supply for the community, using the latest technology to meet required drinking
water standards."
The containerised WTP is expected on-site later this month,
with essential electrical and mechanical installations to be completed before
Christmas. Commissioning of the plant will commence in the new year, with final
compliance testing scheduled for February.
The Owhango water supply is sourced from Deep Creek, a
tributary of the Whakapapa River flowing through the Tongariro State Forest.
Although generally clear, this water source can become turbid during rain
events, prompting the need for precautionary boil water notices.
"The new plant’s advanced coagulation and
ultrafiltration systems, combined with UV disinfection, chlorination, and pH
correction, will filter particles and impurities, delivering crystal-clear
drinking water all year round," Dutra explained. "Additionally, the
plant is designed to conserve water by recycling approximately 90% of its
wastewater back into the treatment process, reducing environmental impact and
waste."
Mr Dutra noted that the end of boil water notices will
undoubtedly be welcomed by Owhango residents and businesses, as well as Council
staff and contractors, who have had to manage community notifications, water
tankers, and other logistical needs—often after-hours—each time a notice was
issued. “This new WTP represents a significant step toward a more secure,
resilient water supply for Owhango,” he said.
