This dataset is used by TCEQ's Utilities & Districts Section to maintain a current digital inventory of all CCNs. This information is used by state and local governmental agencies, water and sewer utility service purveyors and the public. This layer shows the official water CCN service areas that have been designated by the TCEQ. All CCNs go through an application and review process before the boundaries are made official. For more information about CCN Applications please visit the following website http://www.tceq.state.tx.us/permitting/water_supply/ud/publist.html#ccn. |

A Certificate of Convenience and Necessity (CCN) is issued by the 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 data provided in the new Water Utilities Map Viewer delineate the official CCN service areas and CCN facility lines issued by the TCEQ. This dataset is a Texas statewide polygon layer of water Certificates of Convenience and Necessity (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 Water CCN service area data in conjunction with the sewer CCN service areas, water and sewer CCN Facility Line layers. *Important Note: This dataset is constantly being edited as new water and sewer CCNs are created and existing CCNs are amended by CCN and STM applications approved by the Commission. The CCN digital (spatial) data layer is available for download for the entire state of Texas. These CCNs have been checked for accuracy and as of the last publication date represent the official water CCN service areas. These CCNs are maintained and updated using GIS (Geographic Information System) software. |
