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 CCN 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 CCN service area of a retail public utility unless the municipality has a CCN to provide retail water or sewer utility service to that area.

What are the Different 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:

  • Title clearly defines the intent of the application

  • Requested area is clearly identified and labeled in the map title and legend
  • Scale bar is included
  • Neighboring CCN's are not included
  • Requested water and sewer areas are shown on separate maps if the boundaries for each are different
  • Digital mapping data that are shapefiles (.dbf, .shp, .shx, .sbn and .prj)

Additional Tips for Streamlined Expedited Release and Expedited Release Maps:

  • The entire tract must mirror the acreage provided in the deed.
  • Entire tract
    • General location map
    • Detailed map
    • Shapefile of the entire tract
  • Portion of tract
    • 2 general location maps (entire tract and portion of tract)
    • 2 detailed maps (entire tract and portion of tract)
    • 2 shapefiles (entire tract and portion of tract)

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 hard copy maps and digital mapping data identifying the requested area(s). Seven copies of the initial application, including any supplemental items and both physical maps and physical media (ex: CDs, USB flash drives) containing digital mapping data are required with filing an application with the PUC. To help with processing your application, it is helpful for applicants to 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.

Both the hard copy maps and digital mapping data must be filed in the acceptable file format, delivered via one of the approved media formats identified below.

Filing Maps: Each copy of a map must be filed in its original size (to scale).  Maps shall not be reduced or enlarged.

  • File each unique map in a hard copy (paper) format; and
  • File each unique map in an electronic copy (Adobe PDF) format

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

Acceptable File Formats

  • Shapefile (.shp)
  • Geodatabase (.gdb)
  • Drawing file (.dwg)

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.

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.
