ASI personnel have worked on dozens of spillways – from construction to removal and replacement – and we have constructed and maintained fixed crest spillways, concrete structures, training wall, and hydraulic, electric, and manually actuated gates and valves.
The majority of existing dams that are in excess of 25 years old were constructed at a time when spillways and hydraulic structures were designed to pass floods smaller than what modern studies show is possible. Also, as populations grow, more and more people are living downstream of existing dams, which often requires their spillways to be upgraded.
