Project Details

The Lower Colorado River Authority or LCRA is a non-profit public utility that was formed in 1934 by the Texas Legislature. LCRA’s mission is to protect people, property and the environment by providing public services for more than one million people in Central and Southeast Texas.

These services include electric and water supplies, flood management, water and wastewater utilities, public parks along the Highland Lakes and lower Colorado River, and community and economic development services to rural and suburban communities.

Many of the LCRA facilities have pipe, tanks and various steel structures that operate in a highly corrosive environment. Corrosion protection for 2 large ammonia tanks (10 ft tall x 40 ft long) at their Bastrop facility had been a continual battle due to constant sweating.

After many years of painting the tanks (every 3 to 5 years), the LCRA engineers selected the Denso Steelcoat 100™ System for long-term corrosion prevention.

The scope of the work included hand tool cleaning the surface, application of a thin layer of Denso Hi-Tack™ Primer and a double layer of Denso Hi-Tack™ Tape to the tanks and steel support columns. The total surface area protected was approx. 3,100 square feet.

The contractor completed the project in 4 days and the LCRA personnel were very pleased with the results. The large steel tanks will now receive many more years of long-term corrosion prevention.
