Water Quality Management Planning

H-GAC conducts water quality management planning as part of a Clean Water Act Section 604(b) grant program funded by the EPA through the Texas Commission on Environmental Quality. The Water Quality Management Plan Update, completed annually, describes a series of data collection, special study, and coordination activities completed through this project.

The purpose of these activities is to provide data and analysis regarding wastewater infrastructure, watershed planning, and sources of nonpoint source pollution that affect water quality in the Houston-Galveston region.
