On-Site Sewage Research Grants

On Sept. 1, 2011, House Bill 2694 transfers the Texas On-Site Wastewater Treatment Research Council’s (TOWTRC’s) authority and all of its administrative responsibilities to the TCEQ.

The Texas On-Site Wastewater Treatment Research Council (TOWTRC) went through the Sunset Review process in 2010 and 2011. Based on the recommendation of the Sunset Advisory Commission, under House Bill 2694, the 82nd Legislature elected to abolish TOWTRC and to transfer all its administrative responsibilities, including the authority to award grants for on-site sewage research to the TCEQ.

Effective Sept. 1, 2011, the TCEQ assumed all administrative responsibilities including all rights and obligations under existing grant agreements and contracts held by TOWTRC. House Bill 2694 also requires that the TCEQ seek the advice of relevant experts when choosing research topics, awarding grants, and holding educational conferences associated with activities under Texas Health and Safety Code Chapter 367.

Included below are selected TOWTRC Research Projects, and as available, associated reviews by TCEQ staff. Additional reviews will be added as they are completed.
