PROGRAM/ACTIVITY FIELD OPERATIONS
MISSION/PROGRAM DESCRIPTION Utility Field Operations is responsible for the day-to-day operation and maintenance of the water distribution system and the wastewater collection system. The water distribution system consists of more than 200 miles of piping with over 6,500 valves and 2,200 fire hydrants. Water distribution activities involve exercising system valves, collecting water samples, and making necessary system repairs in order to maintain adequate flow and pressure. The Texas Commission on Environmental Quality (TCEQ) mandates that each dead-end line on the distribution system be flushed monthly to help maintain water quality. Dead-end lines typically occur in cul-de-sacs or at the end of streets with only a single point of entry. Because dead-end lines are only tied in to the distribution at one end, the water reaches the end of the line and stops. During periods of low water usage, the water quality at the end of the line can deteriorate. Routine flushing forces the old water out of the line and introduces fresh water. The wastewater collection system consists of over 200 miles of piping and over 3,000 sewer manholes. Wastewater collection activities involve maintaining the system through proactive flushing, cleaning and making system repairs as needed.
GOALS AND OBJECTIVES
*Maintain the water distribution system by repairing leaks and breaks in a timely manner.
*Maintain the wastewater system by making necessary repairs and preforming proactive flushing and cleaning. *Ensure the operability of valves on the water distribution system by routinely exercising and operating each valve. *Maintain water quality in the distribution system by performing monthly flushing activities and by responding to water quality complaints in a timely manner.
