We're building a new Water Treatment Plant for Newport
Background
The City of Newport Oregon has a potable water system that includes many individual components including intakes, piping networks, treatment and storage facilities, and others system components that together provide potable water to the community.
The City completed a master water planning effort that included, as part of the recommendations, a high priority project to address deficiencies related to the water treatment facilities in Newport. (Click on the "City Master Water Plan" tab on the left side of the page for more information).
What's the issue?
The current water treatment plant in Newport was constructed in the 1950’s. The facility utilizes circular solids contact clarifiers, multi-media filters, and liquid hypochlorite disinfection. The plant has been well maintained, though it has begun to show its age with numerous structural, foundation, and process problems, making peak operation a challenge.
The City of Newport water treatment plant is currently capable of treating as much as 4 million gallons of water per day. However, as the plant ages, maintaining peak production at this high rate for extended periods is becoming difficult. Currently, the plant is operated 24 hours per day for periods longer than a month each year as the City struggles to produce the required water for the community. The new plant will be able to treat 7 million gallons a day, (expandable to 10 million gallons a day), enabling Newport to meet demand far into the future.
Where does all the water go?
While the majority of the water use in the community is for domestic purposes, the City provides water to a number of high-water-demand industries. This includes an active fishing fleet, a brewery industry, hotels, restaurants, and others. The highest water demand in the system is recorded annually during the various fishery seasons as fish are processed and other dock activities result in voluminous water consumption.
The Solution:
Water master planning was undertaken by a water system task force with panelists appointed by the mayor. The task force worked in conjunction with HDR, Inc., the consulting engineers, to formulate a set of recommendations that were ultimately taken to the City Council for approval.
A number of alternatives were considered, and the most cost effective alternative was determined to be the construction of a new water treatment facility at the existing site utilizing membrane technology. The new plant is currently under construction and is scheduled to go on-line late spring of 2012. The general contractor is Slayden Construction Group of Stayton, Oregon.
