About TAWC
Founded in 2019 as a chapter of the National Association of Water Companies, TAWC has members located throughout the state.
Our members range in size from large companies with multiple locations to individual utilities serving a few hundred customers. They are operated by men and women who engineer solutions and earn the public’s trust by treating and delivering a vital resource year after year. Through TAWC, our members collaborate, share best practices and leverage their strengths to benefit the communities they serve.
Safe and reliable water service is the lifeblood of our nation. It is essential to the survival of every individual, family and business. As our population grows and pressures our resources, communities will need the experience of well-managed utilities more than ever. Their expertise in the development and implementation of technology and replacing aging infrastructure will have a profound impact on people, business and the environment.

Lorem Ipsum is a simple dummy text from the printing and spelling industry. Lorem Ipsum has become the industry’s standard dummy text since the 1500s, when an unknown printer took a sample and created a sample book. Not only did it survive for five centuries, but it remained largely unchanged even after it made the leap to electronic media. It became popular in the 1960s with the release of Letters containing the Letraset Lorem Ipsum excerpt, and more recently with desktop publishing software such as Aldus PageMaker, including versions of Lorem Ipsum.
Aundrea started working at The Texas Water Company (TWC) on August 21, 2023.
