about us h3oH3O Water Systems is owned and operated by 10 year San Antonio resident, Anthony Moore. Prior to his introduction to the world of irrigation and swimming pools, Tony spent many years as an Environmental Specialist with Space Missile Defense Program (also known as Star Wars). The majority of that time was spent on location in the Marshall Islands, in almost complete seclusion.

Tony quickly learned the importance of being properly prepared, as well as the value found in thinking outside the box. When asked to add any positive attributes to this Bio, Tony replied: “A business owner is only as strong as his weakest employee. I am blessed to be surrounded by the best guys in the business; in both our irrigation and swimming pools departments. I am confident in their abilities and proud to have them as representatives of H3O, more positive attributes cannot be found”.

Tony truly takes great pride in finding, hiring and keeping the very best of today’s swimming pool and irrigation workforce.

With Tony’s background, work ethic and reputable character, his vision for H3O is exactly what you’d expect it should be… “Honesty, Fairness, Reliability and 100% Customer Satisfaction”!
