Houston’s Best Practices for Coating Rehabilitation of Large Diameter Above Grade Water Line Crossings
Available for download

Houston’s water system serves more than 4.5 million people regionally and produces more than 146 billion gallons of treated water every year. The city has more than 300 above-grade water line crossings, some of which have been in service for over 75 years. In 2012, Houston Public Works (HPW) implemented a program to inspect every above-grade water line crossing across the city.

 Houston’s water system serves more than 4.5 million people regionally and produces more than 146 billion gallons of treated water every year. The city has more than 300 above-grade water line crossings, some of which have been in service for over 75 years. In 2012, Houston Public Works (HPW) implemented a program to inspect every above-grade water line crossing across the city. Over 200 crossings were identified as needing repair or rehabilitation, and of those crossings, 21 were considered large diameter, or 24-inches in diameter and larger. In cooperation with HPW and the Surface Water Transmission Program (SWTP), a comprehensive field assessment was performed on these 21 crossings, and criteria was developed to address the deficiencies.

The bridge made the news prior to opening when it was determined that a portion of the support rods were experiencing fatigue and showing signs of premature failure.

Using dehumidification for coatings and preservation has been a widely accepted practice for several decades. Over that time, both the coatings and the dehumidification equipment have grown in complexity. While this has made dehumidification more prevalent than ever, it also has made determining what you need as well as actually getting what you need more complicated than ever.
