Environmental Sustainability

The environment as a whole deserves protecting and nurturing. The Trinity River Authority engages in several efforts to help be a good steward of our one and only environment.

Biosolids are created through the transformation of liquid and solid matter in wastewater. The transformation of what goes down the shower and sink drains, the disposal and toilets in private homes, businesses and restaurants involves physical, chemical and biological processes. 

TRA, in conjunction with the Dallas County Utility Reclamation District, created the first large scale reuse project in Texas. DCURD funded the development of a pipeline and pumping facility that extends from the CRWS plant in Dallas upstream along the Elm Fork of the Trinity River to Las Colinas in Irving.

TRA is moving toward a new way of treating biosolids. Using a phased development process, the solid waste that comes from our homes and businesses will be pasturized and sterilized using thermal hydrolysis and anaerobic digestion.

The Trinity River Authority is a partner in the Village Creek-Lake Arlington Watershed Protection Partnership. A watershed is the land area that drains water to a common point such as a stream, river, lake, wetland, or ocean. Watersheds can be very small, such as part of a park that drains to the creek in your neighborhood. 


Since zebra mussels were first found in Texas in 2009, several Texas lakes and river basins are now fully infested, meaning that zebra mussels have an established, reproducing population. The rapidly reproducing zebra mussels can have serious economic, environmental and recreational impacts on Texas reservoirs.

In August 2011, the Trinity River Authority partnered with U.S. Army Corps of Engineers to be part of the investigation into the potential impacts of zebra mussels. Since that time, TRA has continued to fund the campaign, now managed by Texas Parks and Wildlife Department, to slow the spread of zebra mussels in the Trinity basin.
