Submitted Drillers Reports (SDR) Database
The Submitted Drillers Report (SDR) Database is populated from the online Texas Well Report Submission and Retrieval System (TWRSRS) which is a cooperative Texas Department of Licensing and Regulation (TDLR) and Texas Water Development Board (TWDB) application that registered water-well drillers use to submit their required reports. This system was started 2/5/2001 and began collecting all reports in 2003. Be aware that the locations of the wells in this database are not verified by State staff and may be inaccurate. Added Proposed Use: Fracking Supply in February 2011.
Reports that drillers submitted by mail before the inception date are not included in this database, but are available for access at the Texas Commission on Environmental Quality (TCEQ) Water Well Report Viewer.
