SUBJECT Authorize a contract for the installation of a 48-inch wastewater interceptor main along the northern perimeter of Bachman Lake from Denton Drive to Lemmon Avenue Southland Contracting, Inc., lowest responsible bidder of two - Not to exceed $15,243,612 - Financing: Water Utilities Capital Improvement Funds BACKGROUND This project consists of the installation of approximately 8,210 feet of a 48-inch wastewater interceptor main generally along the northern perimeter of Bachman Lake Park from Denton Drive to Lemmon Avenue. This installation will replace the existing 36-inch and 45-inch wastewater interceptor mains that were built in 1967. Through our inspection and maintenance program, the mains have been identified to be in poor structural condition and requires upsizing to provide additional capacity for the wastewater collection system. Construction of the new line improves system reliability and helps reduce potential sanitary sewer overflows which is one of the main goals by the Texas Commission on Environmental Quality. Completion of the project will reduce operation and maintenance costs and better positions the City of Dallas in meeting regulatory requirements regarding wastewater collection systems. Approximately 5,700 feet of wastewater main will be installed utilizing technologies that when compared to typical open-cut construction methods, will require less excavation, thereby minimizing disturbance to the existing pavement as well as minimizing inconveniences to the public.
