Description: A Certificate of Convenience and Necessity (CCN) is issued by the Texas Commission on Environmental Quality (TCEQ), and authorizes a utility to provide water and/or sewer service to a specific area. The CCN obligates the water or sewer retail public utility to provide continuous and adequate service to every customer who requests service in that area. The maps and digital (spatial) data provided in the new Water Utilities Map Viewer delineate the official CCN service areas and CCN facility lines issued by the TCEQ. The Water Utilities Map Viewer may be accessed from the following web site: http://www.tceq.texas.gov/gis/iwudview.html This dataset is a Texas statewide polygon layer of sewer CCN service areas. The CCNs were digitized from Texas Department of Transportation (TxDOT) county mylar maps. The mylar maps were the base maps on which the CCNs were originally drawn and maintained. CCNs are currently created and maintained using digitizing methods, coordinate geography or imported from digital files submitted by the applicant. TxDOT digital county urban road files are used as the base maps on which the CCNs are geo-referenced. It is best to view the sewer CCN service area data in conjunction with the water CCN service areas, water and sewer CCN facilities line layers. *Important Note: This CCN spatial dataset is updated on a monthly, or as needed basis using Geographic Information System (GIS) software. The official CCN spatial dataset including all types of CCN services areas (water and sewer CCN service areas; water and sewer CCN facility lines) are available for download for the entire state of Texas and is current as of their last updated date.
