About Us

Created by the Texas Legislature in 1969, Gulf Coast Waste Disposal Authority (GCA) is a non-tax supported unit of local government dedicated to waste management activities.

The Authority’s primary jurisdiction, and the area from which the nine-member Board of Directors is selected, is comprised of Harris, Chambers and Galveston Counties.  The Authority may provide services in any part of the State of Texas but coordinates its activities with any other authorities or districts in those areas.

Gulf Coast Authority focuses on providing reliable, cost-effective wastewater treatment and serving as a resource for continued economic development.

GCA owns and operates four industrial wastewater treatment facilities that process liquid wastes from more than 80 petrochemical plants.

Three of the treatment facilities are in Harris and Galveston Counties.  The fourth is located in Odessa, Texas.

The Authority also operates a regional municipal wastewater treatment plant located in Friendswood, Texas.

The Authority industrial solid waste landfill is located in the Texas City area and a trucked-in liquid waste receiving station is operated near the Houston Ship Channel.
