High Water & Sewer Bill Questions

Press Enter to show all options, press Tab go to next option

Recently, there have been many customer inquiries regarding high water and sewer utility bills. The City has prepared the following information to help customers understand the water & sewer utility system.

  • Water consumption multiplied by the rate equals your utility bill.  As your consumption increases, the total cost will increase.  The current water and sewer rates can be seen in the Utility Billing section on the City’s website at
  • Our water and sewer system is run like a business that is self-supported by its customers, rather than by the general taxpayer.
  • Rates are designed to only take in the amount of money needed; there’s no profit margin.
  • If revenues are insufficient, rates must be increased or come from other sources (e.g., property and sales taxes).
  • Revenues are affected by the weather: wet years = less revenue, dry years = more revenue.  Sufficient reserves are required because of this fact.
  • The City has an Inclining Block Rate structure (aka Tiered Rates); meaning rates increase as consumption increases.  These encourage conservation, but also protect lower income residents, because they typically use less water (i.e., 3,000 to 7,000 gallons) and are charged the lower rates.
  • The City has mandatory year round twice a week watering restrictions.  The operation of landscape irrigation systems is limited to the hours between 5pm and 8am of the following day during any two such periods in a given week.
  • Recent water & sewer system capital projects include:
  • Three new water wells
  • Rehabilitation of the existing wastewater treatment plant o Sewer line installations, replacements, and rehabilitations o Sanitary Sewer Overflow Initiative program
  • Sewer line to serve the new Police & Municipal Court Facility
  • Generators to run water distribution sites in case of power outages
  • The above improvements are funded solely by water & sewer system revenue
  • Water and sewer systems must be constantly maintained and are held to very high standards by regulators.
  • The City is expanding its system to accommodate rapid growth in population and commerce.
  • Failure to adequately operate, maintain, and expand the system can cause serious public health problems, which may result in consequences from regulators.
  • Future rate increases are primarily due to the construction of a new sewer treatment plant, which is required by state law.
  • The San Jacinto River Authority (SJRA) Surface Water Conversion Fee and Lone Star Groundwater Conservation District (LSGCD) fee are pass-through fees designed to cover the payments made to these entities.
