Mesa Consolidated Colored Water Treatment Facility

The Colored Water Treatment Facility project was an $11 million design/build effort to produce high quality potable water from naturally colored groundwater. The project included construction of a facility to pump, disinfect, filter, and ozonate groundwater at 4000 gpm to the effect of lowering the water's color units. As Construction Manager, Butier Engineering, Inc. oversaw the following aspects of facility construction:

• 1.25-million gallon capacity water storage tank (prestressed concrete tank designed by DYK) to receive the disinfected product water
• Product water pump station to transfer the potable water from the storage tank into MCWD's existing water distribution system
• Ozone generation system and associated housing structure
• Biologically active filtration
• Disinfection system

Project Challenges/Constraints

Unique to the project was its location in a residential neighborhood. Mesa Consolidated Water District requested the Contractor to abide by certain environmental constraints by responding to the requests of the nearby community. The project team, including Butier Engineering, Mesa Consolidated Water District, and JW Contracting, discussed community's interests at every project meeting. Several challenges addressed by the team were as follows:

• Noise Abatement — Sound walls were installed to both the existing and newly installed well pumps to reduce noise. Additionally, the Contractor did not start work before 8:00 a.m.
• Dust-Prevention — The Contractor continually hosed the project area to keep dust from rising, and applied a coating to dirt piles when not in use.
• Aesthetics — The District and JW Contracting took great efforts to ensure the new facility would not be an industrial "eyesore" to the community. Such efforts included effective architecture, higher aesthetic walls in combination with low rooflines and natural landscaping.
