Dundee council discusses the city's drinking water supply
he Dundee City Council discussed at its Tuesday meeting a water supply study the city commissioned for future development in the Riverside area.
According to council documents, the city is developing "planning-level requirements, codes and standards for the future development of the Riverside area located westerly and adjacent to the Willamette River and within close proximity to the city's wastewater treatment plant."
The development will "significantly increase drinking water demands and tax the city's distribution system." The drinking water supply is provided through wells and due to the increase in demand for drinking water, the city wanted to find viable alternatives to assist with "optimizing, expanding and providing improved redundancy for the city's current potable drinking water supply."
A previous study identified highly treated water from the wastewater treatment facility as "a key potential contributor to help offset the increased drinking water demands associated with development of the Riverside area. Another asset available for consideration is the city's well #4, which is not used for potable water supply because it has been identified as surface water influenced."
The evaluation looked at three questions: how much non-potable water demand is anticipated in the Riverside area for irrigation and other non-potable uses? If this demand is high enough, is it cost-effective or viable to consider using wastewater treatment plant-recycled water or well 3 non-potable water for irrigation and other non-potable uses? And if so, does the use of wastewater treatment plant-recycled water or well 4 non-potable water delay the need for augmenting the city's drinking water demand associated with the Riverside area?
The study found that 75 percent of maximum day water demand is being met, so there is time to address the issue while the city continues to grow. The study recommends constructing a new groundwater well at Falcon Crest Park to increase new term capacity; reevaluating and rehabilitating existing wells; work with Newberg to regionalize efforts; and for Dundee to begin environmental permitting for the future.
