Notice About Confidentiality of Customer Information
Chapter 182 of the Texas Utilities Code as amended in 2021 by House Bill 872 provides that a government-operated utility may not disclose personal information (customer's address, telephone number, and social security number) in a customer's account, or any information related to the volume or units of utility usage or amounts billed or collected for such utility usage, unless the customer elects to allow such information disclosed.
The Utilities Code requires the District to provide notice of the customer's right to allow disclosure of his or her information. Therefore, if you wish to allow disclosure of your personal information, please contact the District Operator, Si Environmental, LLC, via telephone at 832-490-1600 or via email at customercare@sienv.com so they can provide you a disclosure form for you to complete and return.
NOTE: The District is allowed to disclose information in a customer's account record to federal, state, or local government officials; to District employees, officials and operations personnel; to consumer reporting agencies; to a contractor or subcontractor approved by and providing services to the District, the state, a political subdivision of the state, or the United States; or to any other provider of utility services.
