Your Water Bill Explained

Have you ever wondered what fees and charges comprise your water bill? In additional to the amounts charged for water and sewer usage, you will see items for the security fee and the West Harris County Regional Water Authority (“WHCRWA”) pumpage fee.

  • Security fee
    • Currently $5.00 per month. Such fee has been reduced from its highest rate of $7.00 per month in 2014.
  • WHCRWA pumpage fee
    • The WHCRWA assesses fees to Trail of the Lakes Municipal Utility District (the “District”) for every 1,000 gallons of groundwater pumped from the District’s water wells. The WHCRWA fees are passed on to District’s customers based upon usage and at the rates charged by the WHCRWA.  The WHCRWA pumpage fee per 1,000 gallons typically increases annually.

  • Garbage/Recycling charge
    • This cost is included in your sewer rate.  The District’s Board of Directors works to ensure that the District is receiving great garbage service at a competitive price.
  • GBC Opt-In
    • On April 1, 2016, the District began offering its customers the option to make a donation to GBC through voluntary donations included on the monthly water bills. This program affords the general public the opportunity to support GBC’s economic development programs if they so choose. If a customer would like to remove the voluntary GBC fee from his/her water bill entirely, please contact Si Environmental, LLC, the District’s Operator, at 832/490-1600 for removal. If a customer does not wish to make the voluntary GBC donation but chooses to keep the line item on the bill, the customer may pay exactly $1.00 less than is shown as the total amount due on the bill.
