Consider a memorandum/resolution to authorize a Letter of Agreement with Pipeline Analysis, LLC for Wastewater Flow Monitoring Study in an amount of $352,598.
Summary
DATE: March 7, 2023
TO: Kent Cagle, City Manager
FROM: Jeffery Reynolds, Executive Director of Public Works
SUBJECT: Authorize the execution of a Letter of Agreement with Pipeline Analysis, LLC for a Wastewater Flow Monitoring Study
BACKGROUND AND FINDINGS:
In 2009, Pipeline Analysis completed the last citywide wastewater flow monitoring study. This study became the foundation of a ten-year sanitary sewer overflow initiative (SSOI) agreement with the Texas Commission on Environmental Quality (TCEQ) to find and fix infrastructure deficiencies throughout the wastewater system. Killeen's SSOI included the rehabilitation of 2,281 manholes and 91,400 linear feet of wastewater mains, resulting in a sanitary sewer overflow reduction from 95 in 2010 to 8 in 2022.
With Killeen's SSOI agreement with TCEQ complete, city staff recommends continuing the success of the initial SSOI by developing a new program to find and fix wastewater collection system deficiencies. This new series of wastewater rehabilitation projects, which is part of the 2019 Water and Wastewater Masterplan (Project 9S), and was approved in the FY 2023 CIP budget, will begin with a citywide wastewater flow monitoring study. This study will give staff a complete dry and wet weather flow assessment of the wastewater collection system. The flow assessment will prioritize the city's 26 wastewater basins for future evaluation and rehabilitation.
Pipeline Analysis has submitted a professional services agreement that includes temporary wastewater flow monitoring at 26 sites, temporary rainfall monitoring at 8 sites, analysis of systemwide infiltration/inflow, comparison with previous flow monitoring study, and determination of pipeline capacity at each metering site.
