Water System Improvement Project – Vale, Oregon

T BAILEY operated as the general contractor and was awarded the Water System Improvement Project for the City of Vale, Oregon. The project was designed to eliminate toxins from the city’s drinking water, specifically arsenic. The City of Vale received funding from the Federal Safe Drinking Water Revolving Loan Fund which utilizes American Iron and Steel (AIS) Requirements for the Project. AIS requires all building materials utilizing iron or steel products to be produced in the United States.

The Process

T BAILEY operated as the general contractor and was awarded the Water System Improvement Project for the City of Vale, Oregon. The project was designed to eliminate toxins from the City’s drinking water, specifically arsenic. The City of Vale received funding from the Federal Safe Drinking Water Revolving Loan Fund which utilizes American Iron and Steel (AIS) Requirements for the Project. AIS requires all building materials utilizing iron or steel products to be produced in the United States.

The scope of the project included:

  • Building a new 70’ x 60’ water treatment facility
  • Field erecting one (1) AWWA D100 tank 65’dia x 32’tall welded steel water reservoir
  • Field erect two (2) AWWA D100 tanks 18’dia x 29’tall welded steel backwash tanks
  • The project had approx. 8,000 LF of underground transmission water line
  • Modifications to an existing well pump station
  • All associated site work: electrical, controls and instrumentation, plumbing, HVAC, mechanical piping and equipment, building finishes and the final startup, testing and commissioning of the treatment facility.

The project location of the reservoir and treatment facility was located at the City of Vale’s Airport. Vale, Oregon has a very arid environment (hot in the summer months and cold during the winter), so when it came time to excavate, T BAILEY had to be extremely careful as to not create too much dust, as it posed a safety risk to the airplanes nearby. To help keep dust at a minimum water trucks were used.

Working during the cold winter, crews worked to field erect all three AWWA D100 welded steel tanks, along with constructing the foundation for the treatment building. The concrete for the treatment building was poured over the course of several weeks, due to the numerous equipment pads within the building, and in order to meet engineering specifications. The treatment facility was built in accordance with International Building Code (IBC). It was necessary to ensure the concrete cured properly in such a cold environment.

The procurement of the equipment for the job included a pressure filter, booster pumps, backwash recycle pumps, finish water pumps, well pumps and sand filter, plus all of the electric actuated valves and generators. T BAILEY had to ensure that upfront planning and preparation was made in order to ensure all equipment was placed per design and onsite in time to begin assembling the interior mechanical piping system.

Along with the construction and installation of the treatment facility building, the project also required installing approx. 8000 LF of underground water transmission. The water line spanned from the existing well pump station to the new treatment facility; the transmission line ran thru the streets, over a bridge and crossed a main highway. In order to ensure the project was performed safely, careful planning, execution, and traffic control was necessary for the successful completion of this phase of the project.

The project was subject to the mandated provisions of EPA’s American Iron and Steel (AIS) requirements, which meant all permanent construction material which consisted of more than 50% steel was produced in the United States. With these standards, it required extra attention in material submittals and gathering AIS certificates to guarantee and prove all procedures material were in compliance with this standard.
