What is a Certificate of Convenience and Necessity (CCN)?

A Certificate of Convenience and Necessity (CCN) grants a CCN holder the exclusive right to provide retail water or sewer utility service to an identified geographic area. Chapter 13 of the Texas Water Code requires a CCN holder to provide continuous and adequate service to the area within its CCN boundary. Municipalities and districts are not required to have a CCN to serve in areas that are not already being lawfully served by another retail public utility; however, some municipalities and districts choose to obtain a CCN to protect their service area from encroachment. A district may not provide retail water or sewer service within the certificated service area of a retail public utility or within the boundaries of another district without the retail public utility's or district's consent, unless the district has a CCN to provide retail water or sewer utility service to that area. Similarly, a municipality may not provide retail water or sewer service within the certificated service area of a retail public utility unless the municipality has a CCN to provide retail water or sewer utility service to that area.

Types of Certificated Service Areas:

  • Bounded Service Areas:  A certificated service area with closed boundaries that often follows identifiable physical and cultural features such as roads, rivers, streams and political boundaries.

  • Facilities +200 Feet:  A certificated service area represented by lines on a map. They include a buffer of a specified number of feet (usually 200 feet). The lines on a map normally follow along roads and may correspond to distribution lines or facilities in the ground.

  • Facilities Only:  A certificated service area represented by lines on a map. They are granted for a "point of use" that covers only the customer connections at the time the CCN is granted. Facility only service lines normally follow along roads and may correspond to distribution lines or facilities in the ground.

What are the CCN Mapping Requirements for Applications and Petitions?

The following guidance documents and mapping tips provide instructions for creating maps and digital mapping data for applications to obtain or amend a CCN; the sale, transfer, or merger of a utility involving obtaining or amending a CCN; decertification of a utility with a CCN; and requests for streamlined expedited release or expedited release from a CCN.

Guidance Documents:

Mapping Tips for All Detailed and General Location Maps:

  • The purpose of the maps is to show the location of the requested area and to notice the public
  • Maps should be simple, clearly labeled and easy to read
  • The maps must clearly identify the location of the requested area in reference to verifiable man-made landmarks (i.e., roads, railroads, city limit and county boundaries) and natural landmarks (i.e., rivers and lakes)
  • Detailed maps must clearly label verifiable man-made and natural landmarks located to the north, south, east and west of the requested area
  • Map layouts must be either 8.5x11 inches or 11x17 inches to be easily printed for notice purposes
  • Include map title, legend, north arrow, and scale bar
  • Map title clearly defines the intent of the application
  • Map title includes the affected Utility Name(s) and CCN No(s).
  • Clearly identify the outer boundary of the requested area or tract of land on the map and include as a label in the legend
  • The outer boundary of the requested area or tract of land must not be covered by roads or road labels.
  • The requested area or tract of land must not cover roads or road labels.
  • The roads must not be covered by road labels.
  • City limit boundaries, county line boundaries, and hydrology (river, streams, and waterbodies) should follow the same guidance as stated above for the roads and road labels.
  • Maps must not include neighboring CCN boundaries.
  • Requested water and sewer areas must be shown on separate maps if the boundaries for each area are different
  • Digital mapping data that are shapefiles require all the file extensions (.dbf, .prj, .sbn, .sbx, .shp, .shx)

Mapping Guidance for Streamlined Expedited Release and Expedited Release:

To accurately reflect the acreage conveyed in the deed and properly decertify a tract of land from a CCN, the digital mapping data (shapefile) for the tract of land must be generated from a metes and bounds description provided in the deed. PUC GIS Staff analyze the petitioner's maps and shapefile to determine the amount of acreage that may be decertified from the CCN.

  • The petitioner's maps and the shapefile should identify the tract of land conveyed in the deed.
  • The tract of land should match the same acreage provided in the deed.
  • A tract of land may consist of one deed, multiple deeds, or multiple tracts.
  • If a tract of land has one deed, then the petitioner should indicate the location of the tract of land on the maps and shapefiles.
  • If a tract of land has multiple deeds, then the petitioner should indicate the location of each tract, and their associated acreage from the deed, on the maps and shapefiles.
  • If a tract of land has multiple tracts conveyed in one deed, then the petitioner should indicate the location of each tract and associated acreage of each tract on the maps and shapefiles.
  • If there is an acreage difference in the shapefile and the deed, then a revised metes and bounds survey certified by a licensed state land surveyor or registered professional land surveyor is required. The revised certified metes and bounds survey should be used to generate the revised shapefile.
  • Maps should not include neighboring CCN boundaries.

What are the Filing Requirements for Maps and Digital Mapping Data?

When filing applications to obtain, amend or decertify portions of a CCN, or submit a petition for expedited release from a CCN, applicants must file the original general location and detailed map(s) in an Adobe PDF format and digital mapping data (shapefile or geodatabase) identifying the requested area(s) or tract of land. Applicants must electronically upload the Adobe PDF maps and digital mapping data into the PUC Interchange Filer.

Click on PUC Filing Procedures for more detailed information on how to file new applications and supplemental items with the PUC.

Filing Maps: Each map must be filed electronically in an Adobe PDF format in its original scale, color and size. Maps must not be reduced or enlarged.

Digital Mapping Data: All file formats of digital mapping data (shapefile or geodatabase) containing the requested area(s) or tract of land must be georeferenced in either NAD 83 Texas State Plane Coordinate System (US feet) or in NAD 83 Texas Statewide Mapping System (meters). Each shapefile shall include a single, continuous polygon record labeled as the requested area or tract of land. The digital mapping data must be filed in the approved formats identified below.

Acceptable File Formats

  • Shapefiles require all of the following file extensions (.dbf, .prj, .sbn, .sbx, .shp, and .shx) for a usable shapefile
  • Geodatabase (.gdb)

Acceptable Media Formats

  • Data disk (CD)
  • USB Flash Drive

Where can I Download PUC's Water and Sewer CCN Digital Mapping Data?

The PUC's official digital mapping data includes certificated service areas for retail water and sewer utilities. This data is available for download in a shapefile format in the projection, NAD 1983 Texas Statewide Mapping System (Meters). The data includes the current boundaries for the certificated service area issued to each CCN holder. Before filing an application, we suggest using this data to remove any overlaps or gaps with existing CCNs before filing the requested digital mapping data with an application.

Please E-mail water@puc.texas.gov questions you have regarding CCN maps, the CCN viewer or data files.

How do I Use the Water and Sewer CCN Viewer?

The PUC's CCN viewer enables users to search, view and print retail water and sewer certificated service areas for holders of a CCN. The CCN Viewer may be used to search by address to locate the water or sewer CCN service provider. In addition, the CCN Viewer may be used to prepare map filings for applications to obtain a CCN, and amend or transfer a CCN. Before filing an application, we suggest reviewing the existing CCN digital mapping data issued to the CCN holder to be amended or transferred.
