Wastewater Capacity: Updated Data

Post Date:10/21/2025 12:00 PM

Union County Water owns and operates five wastewater treatment plants, or Water Reclamation Facilities (WRF). Each of these facilities treat wastewater from specific drainage areas:

  • Twelve Mile Creek (our primary wastewater treatment plant),
  • Crooked Creek;
  • Tallwood Estates;
  • Grassy Branch; and
  • Olde Sycamore.

Our staff closely monitors the wastewater treatment capacities at these facilities. Permitting capacity is evaluated using the actual plant flows plus the permitted/obligated flows. 

The latest information on our wastewater capacity is published on our website. The information was recently updated and can be found on this page

We invite you to learn more about our wastewater operations and the steps we take every day to protect water quality and the natural environment. You can help support our wastewater operations and protect your property's pipes by putting fats, oils and grease (FOG) and wipes in the trash where they belong.
