Increased system redundancy for operational flexibility
The City of Lubbock, Texas' North Water Treatment Plant currently has a 6 MG ground storage tank (GST) that supplies Pump Station 11 for water distribution. During a freeze event in 2018, the air vent to the tank froze shut causing the tank to over pressurize, resulting in severe structural damage. Increased system redundancy allowed for operational flexibility for tank cleaning and maintenance. Garver also planned for future space requirements for future rehabilitation/replacement of Pump Station 11.
The project also included 48-inch suction and discharge piping with flow control valves and vault. Consideration was given to flexible piping connections at structures to accommodate structure settlement, which will preserve long-term structural integrity. Construction sequencing and tie-ins were designed to accommodate continuous operation of the water treatment plant. The system connects to a 72-inch transmission pipeline, which required Garver to design for specific pressure and surge relief to protect this critical pipeline serving over 300,000 people.
