SUBJECT
Title

*In alignment with Infrastructure Maintenance.
Body
BACKGROUND
The City of Dallas owns and operates two wastewater treatment plants with a combined treatment capacity of 280 million gallons per day. Central Wastewater Treatment Plant (CWWTP) is the largest of the two plants, located just south of downtown. During recent construction improvements, it was discovered that two existing 48-inch diameter influent pipelines, not included with the construction improvements, were in poor structural condition and in need of rehabilitation. A quote was requested to complete the rehabilitation as part of the construction contract but found to be significantly more expensive than expected.
As a result, Dallas Water Utilities Department approached three vendors to obtain quotes to rehabilitate the 48-inch diameter pipelines under an emergency services contract using cured-in-place pipe technology. The three quotes were reviewed and the lowest quote from Advanced Pipe Repair was found to be a good value and properly addressed the technical requirements for rehabilitation of the pipelines. This action will authorize an emergency services contract with Advanced Pipe Repair to complete the rehabilitation of the pipelines and address the structural deficiencies.
The scope of services includes the rehabilitation of two 48-inch diameter pipelines with an internal resin cured liner, each approximately 302 feet in length. Each pipeline conveys wastewater flow from the Dallas Headworks valve pit to Primary Clarifiers A and B. Although the pipelines remain operational, continued deterioration increases the risk of pipe structural failure and potential service disruption and regulatory noncompliance. Failure of either pipeline could result in permit violations and enforcement actions, including fines, from the Texas Commission on Environmental Quality and/or the U.S. Environmental Protection Agency.
In addition, performing the work at this time presents significant operational and cost advantages. The Dallas Plant at the CWWTP is currently offline, and both ends of the pipelines are exposed as part of the ongoing construction of the Dallas Clarifier Improvement Project. Deferring rehabilitation would likely result in substantially higher costs, increased complexity, and greater risk of regulatory violations.
