Michael, a sincere thank you, to you, Mark, and your team. At least 5 others (consultants) blew me off before you guys came through for me. Mark was wonderful to work with. He was diplomatic and patient with the County folks and their processes. And he easily coordinated and worked with the guys from J&J Environmental. He was professional and kept me informed as I anxiously pushed for the next steps. I hope you guys continue to fund work in Calvert County. You have my recommendation. Best in the future.

As the developer of Howard County’s two largest private septic communities (Walnut Grove and Walnut Creek), I would give the Hydro-Terra team an A+ for their design assistance. These two systems support 235 homes. I have worked with Mike Haufler and his team for over 15 years, including years predating the formation of Hydro-Terra. The entire team collaborated in creating a system that was cost effective, plausible for review by state and local agencies, and truly innovative in a number of ways. To date, these systems set the bar for Howard County and would undoubtedly be ahead of their time for the entire State of Maryland.

Hydro-Terra has been a great partner on two of my commercial projects that are on shared Well and Septic systems. They are very knowledgeable about creative, cost effective solutions that perform to standards. Hydro-Terra knowledge of  the regulatory process is indispensable and they are well respected within the government agencies. They have been a great part of our projects success.
