Background Information: The City of Southlake requires the assistance of a third party utility contractor to complete large scale emergency repairs of critical Water and Wastewater infrastructure as the need arises. Smaller scale emergency repairs are performed in-house by Public Works Water Division and Wastewater Division personnel. Public Works utility personnel are able to make repairs on water and wastewater pipes that are less than 16 inches in diameter and at a depth of less than 12 feet. Emergency repairs of leaks and breaks on the 20-inch, 30-inch, 36-inch, and 42-inch diameter water transmission mains are generally at a depth greater than 12 feet and require larger excavation equipment which the City does not own; extensive safety shoring boxes; large cranes; and the fabrication of large segments of custom pipe. Financial Considerations: Expenditures for emergency repairs to the City’s Water and Wastewater utility infrastructure is exempt from bidding under the Texas Local Government Code Chapter 252 Sec tion 252.022 General Exemptions: (a)(2) “a procurement necessary to preserve or protect the public health or safety of the municipality’s residents.” Funding for Water and Wastewater utility infrastructure repairs and system maintenance is budgeted in the FY 2019 Public Works Operating Budget. Item 4E In FY 2018, the City spent $46,880 on emergency utility repairs with Wildstone, and in FY 2019 to date, $43,050 has been encumbered for emergency repairs.
