Update of the Tarrant Regional Water District Eagle Mountain Connection Project

摘要

Tarrant Regional Water District (TRWD) supplies raw water to over thirty wholesale customers (approximately 1.6 million people) in ten Texas counties. TRWD's existing raw water supply system includes two major reservoirs in East Texas, pipelines and pump stations to deliver water from East Texas to Tarrant County, the West Fork reservoirs, two terminal storage lakes in Tarrant County, and the Benbrook Connection, which delivers East Texas water to the southwest side of Fort Worth. The Eagle Mountain Connection Project will allow TRWD to pump water from their East Texas Reservoirs to Eagle Mountain Lake, which is one of the West Fork reservoirs. The $130-million project will allow TRWD to meet increasing demands in their West Fork service area and will result in power cost savings while increasing the available yield of the TRWD water supplies and the reliability of the TRWD system. The project includes 19 miles of 96-inch (244-cm) and 84-inch (213-cm) pipeline to connect TRWD's East Texas System to their West Fork System, two booster pump stations, a 120-million-gallon balancing reservoir, and a number of other required facilities. This paper presents a project update and lessons learned from the System Reliability and Enhancement Study, Pipeline Route Studies, Operational Study, and Preliminary Design Phases of the project. The project is currently in the Final Design Phase. Construction is scheduled to begin in May 2006.
