Design/Assist & Mechanical Piping Services

VALUE DELIVERED

Preparedness for meeting the city’s future clean water requirements.

DESIGN/ASSIST & MECHANICAL SERVICES SCOPE OF WORK

During the design and permitting process, UMEC (AZ) is providing design/assist services to the engineer and general contractor. This early input on constructability issues helps ensure an efficient, cost-effective approach. Once this process has been completed, UMEC (AZ) will provide full mechanical services, including installation of all process piping for the plant's chemical and disinfection systems, as well as filter piping, solids-handling system piping and equipment, and taste, odor, and organics removal piping. The company will also install ozone and UV systems piping, construct the carbon regeneration facility, and implement basic mechanical systems for the facility's visitor center.

WATER TREATMENT FACILITY BACKGROUND

The City of Phoenix provides wastewater collection for about one million people in a 530 square-mile area. To handle this, the City operates two wastewater treatment plants with a combined capacity of about 242.25 million gallons per day and about 336,000 wastewater service connections. The city maintains approximately 4,363 miles of sewer lines. Over the next two decades, the city anticipates growth of up to 300,000 households at its far northern frontier.

This water treatment facility is intended to meet the clean water need this explosive growth will present.

MECHANICAL CONSTRUCTION OBJECTIVES

To provide mechanical construction for a water treatment plant with an initial capacity of 80 mgd, expandable to 320 mgd.

DESIGN/BUILD SOLUTIONS

UMEC (AZ) has constructed, maintained, or repaired numerous water and wastewater treatment facilities in the Phoenix, AZ area, including the Phoenix 23rd Avenue and 91st Avenue Wastewater Treatment Plant expansions, Scottsdale Water Campus, the Scottsdale Central Arizona Project Treatment Plant expansion, and the Val Vista Water Treatment Plant expansion

For this design/build project, the City of Phoenix decided that, rather than take a traditional design-bid-build approach, it would pursue an innovative design-build-operate delivery strategy. This requires UMEC (AZ) to work as part of a team with the facility operator, the general contractor, and the architect/engineering firm to provide the project’s full scope of services. As part of the team’s commitment to high-level communication and continuity, it has established a centralized office in Phoenix, enabling close coordination both among themselves and between the team and the Phoenix Water Services Department.
