Frequently-anticipated questions:

What does this data set describe?

Title: SDETrims.DBO.Hydro_Dischargers
Abstract:
This layer contains locations and associated database information for permitted municipal & industrial wastewater quality outfalls. An outfall is defined as any point source discharge from a domestic or industrial facility. Some of the outfalls in this layer also represent stormwater discharge points.

The horizontal accuracy of this layer is represented by the following figures:

12-meter accuracy (60%) 315-meter accuracy (40%)

Supplemental_Information:
Information on a given water quality permit is only as current as the most recent application. Water quality permits are renewed approximately every five years. In order to maintain the most accurate set of locational data for water quality permits, the locational database is updated as wastewater permits are newly issued, outfalls change locations, and/or improved locational information becomes available.

For more information about water quality permits, please visit TCEQ's Water Quality Permits and Registrations page.

  6. How does the data set represent geographic features?

    1. How are geographic features stored in the data set?

      This is a Vector data set. It contains the following vector data types (SDTS terminology):

      • Entity point (640)

    2. What coordinate system is used to represent geographic features?

      Horizontal positions are specified in geographic coordinates, that is, latitude and longitude. Latitudes are given to the nearest 0.000000. Longitudes are given to the nearest 0.000000. Latitude and longitude values are specified in Decimal degrees.

      The horizontal datum used is North American Datum of 1983.
      The ellipsoid used is Geodetic Reference System 80.
      The semi-major axis of the ellipsoid used is 6378137.000000.
      The flattening of the ellipsoid used is 1/298.257222.

Why was the data set created?

Primarily the TCEQ Wastewater layer is used to identify the geographic location of wastewaster outfalls within the state of Texas. This data layer can be used for a variety of purposes, including: the plotting of wastewater outfall sites on maps; determining the permitted discharge facilities within a 3 mile radius; determining upstream dischargers; utilization by field personnel; and performing spatial analysis on how the sites affect their surroundings.
