Groundbreaking Ceremony

Thank you to everyone who attended the Groundbreaking Ceremony on May 22, 2015. We had to move indoors due to the rain but still had a nice time celebrating this exciting step for our wastewater treatment plant improvements. The video replay is now available on YouTube.

In December 2014 and February 2015 the District issued bonds to fund needed improvements to the wastewater treatment plant. The plant will utilize a state-of-the-art treatment process known as Membrane Bioreactor System (MBR) to treat wastewater to a purity level that meets current State standards and new limits expected in the next permit.

The District accepted competitive sealed bids for construction of the new facility. The Board of Directors awarded the contract to Webber/Cadagua, and the project will be overseen by engineers from The Wallace Group. Construction is expected to begin in late May, 2015 and take approximately 18 months for completion.


The Trophy Club Municipal Utility District No. 1 maintains a Wastewater Treatment Plant at 1499 Junction Way (at the end of Indian Creek past the Harmony Park area).  Please contact Wastewater Superintendent Karl Schlielig at 817-430-1218 for more information.



How does the treatment plant work?

Here’s a step-by-step guide describing what happens at each stage of the treatment process and how pollutants are removed to help keep our waterways clean.

1. Screening: Wastewater entering the treatment plant includes various solids.  Unless they are removed, they could cause problems later in the treatment process. These materials are screened out, bagged and sent to a landfill.

2. Pumping: Many wastewater systems rely on the force of gravity. Trophy Club has ten lift stations (which are mostly located on the east side of town) to move sewage to the treatment plant.  Our plant is built at one of the lower points in Trophy Club so the lift stations only have to pump the water to where the ground starts dropping to turn it into gravity flow. The wet well is 32’ deep and wastewater is pumped from there to the screening process, and then gravity takes over throughout the plant unless the different steps are required to recycle the wastewater back to the head of the facility.

3. Biological Treatment:  Aeration basins provide an aerobic environment that promotes bacteria to metabolize organic matter. This is achieved by creating an environment where the oxidation and stabilization can take place, thus allowing pollutants that can negatively impact the receiving stream to be removed.

4. Sludge Removal: Wastewater is then pumped to large circular tanks called sedimentation tanks or clarifiers. Here, the sludge (the organic portion of the sewage) settles out of the wastewater and is pumped out of the tanks.   The majority of the water is decanted from the top and the sludge is then pumped to and processed in large tanks called digesters. Most of the sludge is sent back to the aeration basins to keep a continuous flow of microorganisms so the majority of incoming organic load can be absorbed. This is called Return Activated Sludge (RAS).

5. Scum Removal: As sludge is settling to the bottom of the sedimentation tanks, lighter materials float to the surface. This ‘scum’ includes grease, oils, plastics, and soap.  Very little scum is collected in our operation but when needed, it is vacuumed from the tanks and pumped to the digesters along with the sludge.

6. Killing bacteria: Finally, the wastewater flows through a final filter, then into an ultraviolet contact tank, where the water is subjected to a battery of UV light to kill bacteria that could pose a health risk. The treated water (called effluent) is then discharged either to Marshall Branch or to a holding pond at the Trophy Club Country Club, where it is used for watering the golf course.

7. Wastewater Residuals: Another part of treating wastewater is dealing with the solid-waste material. These solids are kept for 20 to 30 days in large tanks called ‘digesters.’ Here, bacteria breaks down or digests the material, reducing its volume, odors, and getting rid of organisms that can cause disease. The finished product is pumped to a filter press where the water is removed and the sludge is sent to landfills.  Liquid from the filter press is returned to the start of the process.
