What Our Clients Say

“Because of the recent historic drought, the directive from City leadership on operation of the new Hamby Water Reclamation Facility was to be at a level of operation required to safely send reclaimed water to Lake Fort Phantom Hill within a month of completing major construction at the facility. A normal facility upgrade project requires 6 to 12 months of operation to get used to the new technologies. With the aggressive startup schedule required for this project, eHT conducted bi-weekly operator training workshops with the City operating staff to review process theory, typical and emergency operating requirements and optimization and troubleshooting approaches for each new treatment process. Then, as the units were being built, the operators had a better understanding of the layout of each process and what equipment to expect and how it would function. Thanks to the training workshops, City operators not only gained a level of comfort with the new technologies, but the operators rapidly took ownership in the new facility and began producing high quality reclaimed water to Lake Fort Phantom Hill in early January 2015, less than a month from completing major construction.”

Assistant Director of Water Utilities, City of Abilene

I've had the opportunity to work with several firms in the State of Texas and across the country and one of the things that I think is always important to me is that the size of the firm - just because it's a larger firm - does not necessarily mean that you're going to get more expertise or even a better project. A lot of times working with a smaller firm you're actually working with the people who are committed to that organization whether it's the owners or people that are involved in ownership and my experience is that the service that is provided is usually above and beyond what you would normally expect. They are committed to the project. And that was the experience we had in Missouri City with eHT.

Former Water Utilities Director, City of San Angelo

Applying for state funds was a daunting task for us. Our need was great, the competition fierce.  Our economically disadvantaged community didn’t know how to present our problem in a way to garner a favorable result. 

eHT stepped in!  They researched our geographic area, compiled the statistics and represented us better than we ever imagined!  They have been staunch advocates for our community.  Thanks to their guidance and tireless efforts, our project is fully funded and due to begin very soon.   We are forever grateful for the expertise of eHT, their engineers and staff.

“The City of Eden has a fantastic partnership with our engineering firm eHT. We are a small City and cannot afford to have staff engineers but we feel as if that is exactly what we have with “our” engineers at eHT. For many years, the City has faced enforcement actions by TCEQ for water quality issues involving radium, and with the help of eHT, we are on the road to compliance. eHT has been invaluable in assisting the City to find funding for much-needed projects which include a new water well, water line replacement and the new water treatment plant that will remove the radium. Every step of the way, from funding opportunities to project design, construction and completion, the team at eHT has been very informative and professional. The engineers at eHT go above and beyond and have even returned a frantic Saturday afternoon phone call or two and they always have the best interest of the City at heart. I would highly recommend eHT if you are looking for a full-service engineering firm for any project large or small.”
