Customer Account Services (CAS) provides customer information, billings, credit, collections, and all meter-associated   services to water and wastewater utility customers within the City of Houston.   Additionally, CAS provides wholesale water services to many nearby towns and   utility districts, and bills for the Solid Waste Add-A-Can Program.

Customer Account Services provides these services to approximately 2.1 million residents   in Houston, generating over $600 million in gross revenue. The funds generated  by CAS are used by other divisions of Public Works and Engineering to support   and maintain the city's water and wastewater systems. With such a high profile,  CAS is often mis-named as the "Water Department". The City of Houston does not   have a department by that name; instead the functions are divided among branches   of the Resource Management and Public Utilities divisions.

Our goal is to consistently meet the expectations of every customer by offering   outstanding customer service, increased flexibility, greater value, and improved   operational efficiency.  Each year, our Customer Contact Center handles an   average of 600,000 calls and Field Operations team travels in excess of   2,000,000 miles to cover an 800 square-mile area.

The drive to   constantly improve service and process technology is strongly visible. The City   of Houston was the first major city in the U.S. to use in ground automated water   meter reading (AMR) technology. Utility company managers from all over the   country come to Houston to inspect our state-of-the-art payment processing   equipment and our Automatic Meter Reading Program.
