Brazos Research Wetland

Project Summary

The goal of this project is to construct a wetland to study and evaluate how endocrine disrupting compounds can be reduced or removed from treated wastewater effluent. The design of the wetland is new and innovative, incorporating a unique combination of surface and subsurface treatment zones, as well as passive aeration units including cascades and turbulent stream channels. The main deliverable for the project will be technical resource document on the design and operation of treatment wetlands.

TWDB Share of Project Cost:

Constructed wetlands have longer hydraulic and solids residence times, diverse environmental conditions, and natural attenuation that may provide a more cost-effective alternative to chemical and membrane treatment processes while also providing important environmental and social benefits. The overarching goal is to demonstrate that constructed wetlands are viable treatment components and can be used for indirect potable reuse to produce a new water source in Texas. The resource document can be used by other communities interested in exploring or pursuing water reuse.
