Water Utilities

The City of Denton Water Utilities provide 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 in stormwater monitoring and drinking water quality protection. The laboratory performs approximately 30,000 analysis per year and is able to perform bacteriological testing on water samples submitted by the public.
  • 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 David Hunter at (940) 349-7123.

  • Watershed Protection
    Watershed Protection is a division within the Environmental Services and Sustainability Department. The Watershed Protection Program was initiated in January 2001 as a part of a plan 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. As a NPDES phase II City, Denton operates and maintains a ‘municipal separate storm sewer system’ or MS4 for residents and businesses within the City of Denton.

    Watershed Protection services include (but not limited to):
    • Detecting and eliminating illicit discharge
    • Construction stormwater inspections
    • Review of Stormwater Pollution Prevention Plans (SWPPPs) and erosion control plans
    • Ensuring regulatory compliance with NPDES
    • Environmentally Sensitive Area Assessments
    • Coordination of City of Denton Volunteer Environmental Monitors
    • Industrial stormwater inspections
    • Municipal good housekeeping
    This program incorporates the infrastructure established by an Environmental Protection Agency EMPACT grant awarded to the City of Denton and the University of North Texas in 1998. During the first year of the Watershed Protection Program, monitoring results from the EMPACT system and additional watershed monitoring were used to establish preliminary baseline conditions for the physical, chemical, and biological components of the city's surface water resources. Results from this monitoring program are used to support the requirements of the Phase II storm water program, assess water quality for the purposes of source water protection, and establish baseline conditions that can be used to evaluate any future changes in water quality.

    Cooper Creek, Hickory Creek, Pecan Creek and Clear Creek are the four main watersheds that convey water through Denton. Using topographical information, approximately 85 sub-basins have been delineated within the city. Sampling stations were established within these sub-basins at locations that would likely represent the water quality of the sub-basins. Monitoring of these sub-basins during base-flow conditions was initiated in January 2001 and has continued on a monthly basis ever since. Parameters analyzed in the tributary samples include conventional flow, temperature, dissolved oxygen, pH, conductivity, turbidity, salinity, litter index, visual evaluation and odor.  Bimonthly, ten sampling stations are randomly selected for more intense analysis which included E. coli bacteria, metals, phosphorus, nitrogen, ammonia, nitrate, chlorides, sulfates, alkalinity, hardness, total solids and total suspended solids.

    Permanent monitoring stations were established near the ends of the three major watersheds (Hickory, Pecan and Cooper Creeks) prior to the confluence of the watersheds with Lewisville Lake. These include a station above and below the Pecan Creek Water Reclamation Plant's outfall. More extensive monitoring is conducted at these stations to provide a more comprehensive assessment of the combined effects of sub-basin water quality just prior to entering the city's main drinking water source, Lewisville Lake.
    The data from the stream monitoring program are analyzed with the following objectives:
    • Characterize the general water quality condition of the stream
    • Identify illicit discharges
    • Identify long-term water quality trends
  • Plant Tours & Presentations
    The City works closely with the University of North Texas, Texas Woman’s University, and the Denton Independent School District to provide educational plant tours of the Lake Lewisville Water Treatment Plant and the Pecan Creek Water Reclamation plant. The City also provides presentations on a variety of water-related topics, including water conservation and protection, stormwater pollution, and careers in the water industry. To schedule a plant tour or presentation, contact David Hunter at (940) 349-7123 or David.Hunter@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

Frequently Asked Questions

  • What is the Drainage Fee based on?
    The Drainage Fee is based on impervious surfaces within the city. Impervious surfaces, measured in square feet, represent surfaces that contribute runoff into the storm water system. Impervious surfaces include the basic building structure, garages, roofs, patios, driveways, parking lots, etc.
  • How can I request a review of the rate block or square footage total?
    To request a review of the rate block (residential) or square footage total (non-residential), you may download a drainage review request form by clicking here or you may obtain one from Utilities Customer Service. The online form is in PDF format.

    Complete the review request form and attach the data sheet obtained from the Denton County Appraisal District at 3911 Morse Street or by visiting their web site http://www.dentoncad.org. Please return the completed review request form and attachments to Utilities Customer Service, at City Hall East, 601 E. Hickory Suite F, or City Hall in the Mall, Golden Triangle Mall next to Old Country Buffet.
  • Why do I have to pay to meet EPA requirements?
    The EPA now enforces strict storm water drainage regulations under the Clean Water Act. These regulations are the result of an unfunded federal mandate to clean up pollution from storm water, which drains into rivers, lakes, and streams. Because these regulations are unfunded, each city must pay to meet these requirements. The monthly drainage fee in part pays for work we must do to meet these new EPA drainage standards and requirements.
