Woolpert Selected for Oklahoma City Multimillion-Dollar Sanitary Sewer Project

The Oklahoma City Water Utilities Trust (OCWUT) has signed Woolpert to an eight-year, multimillion-dollar contract to provide asset management and sewer condition assessment services.

As the city’s policy-making body for water and wastewater utilities, OCWUT owns and maintains nearly 3,000 miles of sanitary sewer gravity lines throughout the city that range from 4 to 96 inches in diameter. These lines are connected by nearly 70,000 manholes, chambers and cleanouts.

Woolpert will perform a detailed condition assessment inspection of these sanitary sewer assets using closed-circuit television (CCTV), sonar, geographic information system (GIS) mapping, 3D scanning and multi-sensor inspections. The information will be used to establish an asset management program based on the likelihood and consequence of failure for assets across the system. It will also form the basis for OCWUT’s annual Capital Improvement Prioritization Report, and Operations and Maintenance Work Plan.

According to Carla Muscarella, Woolpert project manager, the project will protect OCWUT’s more-than-$1.5-billion investment in its infrastructure and ensure residents have consistent, reliable services.

“This project will transition OCWUT to a comprehensive, streamlined operation that prioritizes the maintenance, rehabilitation and replacement of its assets,” Muscarella said. “This will vastly improve the system’s resiliency and longevity and allow the city to focus its planning and field resources.”
