Harris County M.U.D. #389 - Use the right payment platform

Dear residents, it's been brought to our attention that an unofficial MUD #389 account was set up on an external payment platform we are not affiliated with, called DOXO. Please DO NOT USE DOXO to pay your bill. The only correct payment link for MUD #389 is https://h2o.starnik.net/.

We are working to correct this situation as soon as possible.

Rates explanation - All customers

H2O Innovation is the billing and collection agent for the water District that you live in. We are NOT the District. We are bound by the District’s Rate Order or Tariff to enforce the water and sewer rates, late fees, disconnect fees, deposit fees, application fees, rules and regulations set forth by your Water District. We have no authority to waive deposits, cut off fees, late fees or make exceptions for any customer without consent of the Board of Directors of your District.

What is a Rate Order or Tariff

The Rate Order or Tariff is a legal document created by each Utility District. The Rate Order or Tariff specifies the rates that are to be charged to all of its customers. It sets policies and procedures for monthly water and sewer service rates for all user classes, security deposit schedules for customer accounts, penalty fees for delinquent accounts, disconnect fees for delinquent accounts, procedures and important dates for billing of accounts. The Rate Order or Tariff also sets requirements for new water taps and connections to the District’s system and water tap fee schedule.
