Desalination Plant Database

The desalination plant database contains detailed information on public water supply desalination plants currently operating in Texas. The desalination plant database was initially developed in 2005 by the Bureau of Economic Geology for the TWDB under the terms of Contract 2004-483-021. The database was later updated in 2010, 2015, and 2020 by the TWDB staff. Information for the database was gathered primarily through self-reported surveys emailed to the utilities and cities and TWDB staff calling utilities to follow-up on information. Only public water supply plants with a capacity greater than 0.025 MGD are included in the database.

Desalination Database can be accessed via:
