Dixon Duff Dryden, 75, was born February 24, 1951, in Houston, Texas, and passed away June 2, 2026. A longtime resident of Manvel, Texas, Dixon built a life defined by steady work, perseverance through every season, and a deep love of country and community.
Dixon devoted his career to wastewater treatment system installation and maintenance and was the owner of Environmental Construction Services. He was a highly respected founding member and past president of the Texas Onsite Wastewater Association (TOWA), where he helped shape the onsite wastewater industry and worked alongside state regulators, including the TCEQ. His professional life reflected a rare combination of grit and reliability—showing up, solving problems, and seeing things through. Dixon also served in the Army, carrying forward a quiet, enduring patriotism that guided the way he lived and worked.
In addition to his professional commitments, Dixon gave generously of his time as an adult leader in Cub Scouts and Boy Scouts for many years, offering steady guidance and support to young people and fellow volunteers alike.
Dixon found joy in the outdoors and in making things with his hands. He enjoyed hunting and fishing, and he took pride in gardening and woodworking—interests that suited his patient, capable nature and his appreciation for honest effort.
He was married to Susan “Susie” Dryden for 40 years; a partnership rooted in devotion and constancy.
Dixon was preceded in death by his father, Carl Armour Dryden; his mother, Fay Pullin Dryden; his sister, Mary Bland; and his brother, Bobby Dryden.
He is survived by his wife, Susan “Susie” Dryden; his children, Jason Dryden (Jennifer), Daniel Dryden, Jennifer “Jenny” Dryden (Isaiah Choy), and Jordan Dryden; and his grandchildren, Mason Dryden, Alyssa Armstrong, Quinn Choy, and Levi Choy.
