Water Treatment Plant Construction

The City of Granbury is in the process of building a new water treatment plant to be able to provide drinking water for the community and meet the future needs of Granbury’s growing population.

Currently, The City operates a .48 MGD surface water plant, 34 groundwater wells, and purchases water from BRUPA surface water plant (formerly BRA SWATS plant) in order to meet the community’s water needs. The existing facility was constructed in 1985 is not able to meet Granbury’s current water demands.

By building a new water treatment plant, the City will be able to provide the amount of water needed ensure a much higher quality of drinking water. The construction of the plant will also eliminate the need to purchase water from BRPUA SWTP. The new plant will use microfiltration and reverse osmosis methods to treat the high levels of salinity in the water in Lake Granbury. All water treatment will meet Texas Commission on Environmental Quality (TCEQ) requirements.

The water treatment upgrades are designed in three phases. Phase one, which will be complete when the plant opens in fall 2017, will be able to produce 2.5 million gallons of water per day. This will meet Granbury’s current daily water requirements, except on peak demand days when groundwater wells would supplement demand.

Phase One: 2.5 million gallons per day – October 2017
Phase Two: 5.0 million gallons per day – as needed, based on capacity projections
Phase Three: 7.5 million gallons per day – as needed, based on capacity projections

The current water treatment plant remains open and operational until the new plant is completed. The new plant is scheduled to be open and operational in fall 2017.

Water Treatment Plant Construction Updates

February 1, 2016: Construction for the water treatment plant began with initial clearing and excavating.
September 2016: Multilevel concrete slab and piping structure was completed.
January 2017: Walls, precast walls, and double tee roof were completed.
March 2017: Crews are working on electrical work, assembly of microfiltration and reverse osmosis skids, and construction of the flocculation basin area of the plant.
April 2017: The building and roof of the main center is completely constructed. Rooms inside the building are framed in. Membrane, controls, and lighting are in the process of being installed. The flocculation basin has been excavated and is being constructed. The existing ground storage tank is being refurbished.
August 2017: The ground storage tank rehabilitation has been completed. Flocculation basin construction and the 24-inch overflow line to the lake are complete. The Pall membrane microfilter and reverse osmosis equipment is approximately one month from being fully installed. The chemical storage tanks, feed pumps, and the high service pumpWaterProjects102417_1 station are nearly complete. The power generator has been installed, and electricians continue to run wire and controls to the building.
October 2017: The pre-treatment raw pump station, flocculators, and plate settlers are in and have been leak and function tested. Start-up chemicals are delivered and are undergoing lab tests for dosage rates. The micro-filtration skids are installed and water is being run through the system to test integrity. All pieces of the reverse osmosis filtration have been installed. Office and lab installation is finishing. Operator training has begun.

Plant Capacity

The water treatment upgrades are designed in three phases. Phase one of the plant, which will be complete when the plant opens in fall 2017, will be able to produce 2.5 million gallons of water per day. This will meet Granbury’s current daily water requirements, except on peak demand days when groundwater wells would supplement demand. 

The three phases for water production:

• Phase One: 2.5 million gallons per day – Fall 2017
• Phase Two: 5.0 million gallons per day – as needed, based on capacity projections
• Phase Three: 7.5 million gallons per day – as needed, based on capacity projections
