The City of Denton Water Utilities provides high quality water and wastewater, and drainage services at an affordable cost while striving for exceptional customer service and environmental stewardship.

During Business Hours​ After Business Hours​
  • For all utilities-related incidents, including service interruptions, call (940) 349-7000.
  • To report illegal dumping, call the Police Department at (940) 349-8181.
  • Municipal Laboratory
    The Denton Municipal Laboratory provides technical support to the following Divisions:
    • Water Production
    • Wastewater Reclamation
    • Industrial Pretreatment
    • Watershed Management
    The laboratory, located at 1056 S. Mayhill Rd., 76209 (same location as the Pecan Creek Water Reclamation Facility), is National Environmental Laboratory Accreditation Program (NELAP) certified to perform bacteriological testing on water and waste water samples. This certification allows the lab to perform bacteriological testing on samples submitted by the public and other municipalities. The analysis fee is $20 - $25 per sample (depending on test type) which includes sample container, Chain-Of-Custody sheet, consultation and sampling instructions.

  • Drainage
    The Drainage Division maintains the city storm water drainage system, which directs all storm runoff to Denton's three creeks: Cooper, Pecan, and Hickory, which channel it to Lake Lewisville. The Drainage Division is also responsible for closing floodgates, placing high water barricades on city streets during floods. Drainage programs are paid for by a drainage fee, which is dedicated solely to that purpose.
  • Sanitary Sewer System Overflows
    Occasional unintentional discharges of raw sewage from municipal sanitary sewers occur in almost every system. These types of discharges are called Sanitary Sewer Overflows (SSOs). The EPA estimates that there are at least 40,000 SSOs each year. The untreated sewage from these overflows can contaminate our waters, causing serious water quality problems. It can also back-up into basements, causing property damage and threatening public health. If you see or suspect there is an overflow please call (940) 349-8400.
  • Inflow & Infiltration
    Inflow and infiltration is water that enters the sewer system through cracked pipes, leaky manholes, broken cleanouts, and improperly connected storm drains and down spouts. Inflow generally comes from rain, while infiltration comes from groundwater. The City constantly works to reduce inflow and infiltration through smoke testing, dye testing, TV inspection, and flow monitoring. For more information regarding inflow and infiltration, call (940) 349-8489.
  • Wastewater and Treatment

    The Wastewater Utility manages the daily operations of Denton’s wastewater system. The Division supports the collection system to 125,000 sanitary sewer customers and responsibilities include daily operation and maintenance of the wastewater collection system, sewer manholes, sanitary sewer lift stations, and compliance with the Clean Water Act.

    The Pecan Creek Water Reclamation Plant treats about 15 million gallons per day. Our plant meets some of the strictest discharge standards to protect the quality of Pecan Creek, and meets all Environmental Protection Agency and Texas Commission on Environmental Quality permits and regulations. The City has an Industrial Pretreatment Program developed according to EPA and TCEQ regulations. This program assists commercial and industrial users in complying with EPA wastewater discharge regulations. For more information, call Heather Goins at (940) 349-8610.

  • Wastewater Collection System Smoke Testing

    To perform smoke testing, crews access manholes and force air combined with non-toxic smoke into sewer mains to discover the locations of leaks and non-permitted connections. Smoke testing helps locate defective openings and inappropriate connections in the City’s sewer system that allow rainwater runoff to enter, decreasing the system’s capacity and ability to handle normal flows. By finding and repairing these defects, the city is able to defer expensive infrastructure needs and reduce the burden on utility customers.

    A defective opening is detected if smoke is seen coming up out of the ground or other unexpected locations. During testing, residents will see smoke exit from rooftop vents pipes on homes and commercial businesses, from manholes, and from the ground where broken sewer pipes may exist. The smoke is non-toxic, creates no fire hazard, leaves no residue, dissipates quickly and is harmless to animals. The smoke will not enter a home or business unless there is defective plumbing present, or the drains have dried out.

    When wastewater collection system repairs are needed, City crews will schedule repairs and notify homeowners in advance of the work. Due to the number of defects typically identified during this process, repairs may be scheduled several months after smoke testing is completed. 

    For any questions, please call or email Tyler Dawson, Field Service Tech Manager, at Tyler.Dawson@cityofdenton.com or (940) 349-8944.

  • Watershed Protection
    The Watershed Protection division administers programs to reduce the overall pollutants within the surface waters of Denton and to ensure compliance with the National Pollution Discharge Elimination System (NPDES) Storm Water Phase II rule. The mission of the Denton Watershed Protection program is to maintain the surface water quality of each watershed, ultimately protecting our water sources and the ecosystems within our watersheds.
  • Plant Tours & Presentations
    To reduce the spread of COVID-19, water and wastewater plant tours are currently suspended. For more information, please contact us at watershed@cityofdenton.com.
  • Drought Contingency Plan
    Recognizing the need for efficient use of existing water supplies, the Texas Commission on Environmental Quality (TCEQ) has developed guidelines and requirements governing the development of water Conservation and drought contingency plans for public water suppliers. The City of Denton has adopted this water conservation and drought contingency plan pursuant to TCEQ guidelines and requirements.
  • The objectives of the water conservation plan are:
    • To reduce water consumption.
    • To reduce the loss and waste of water.
    • To identify the level of water reuse.
    • To improve efficiency in the use of water.
    • To extend the life of current water supplies by reducing the rate of growth in demand.
  • The objectives of the drought contingency plan are:
    • To conserve the available water supply in times of drought and emergency
    • To maintain supplies for domestic water use, sanitation, and fire protection
    • To protect and preserve public health, welfare, and safety
    • To minimize the adverse impacts of water supply shortages
    • To minimize the adverse impacts of emergency water supply conditions
