Rehabilitation of an Aging Concrete Reservoir Adit Tower

Rehabilitation of an Aging Concrete Reservoir Adit Tower
Available for download

Adit towers are generally vertical, large diameter concrete pipes that serve as vaults for valves used to drain and fill a reservoir. The tower runs from several feet above the waterline down through the reservoir and into the reservoir bed for some distance. Many of these towers and reservoirs are old and deteriorating, as the United States suffers from an aged infrastructure.

Adit towers are generally vertical, large diameter concrete pipes that serve as vaults for valves used to drain and fill a reservoir. The tower runs from several feet above the waterline down through the reservoir and into the reservoir bed for some distance. Many of these towers and reservoirs are old and deteriorating, as the United States suffers from an aged infrastructure. External cracking is common above the waterline; weeping and leaking cracks are often present on the interior, and the valves, piping and infrastructure (stairways, pipe supports and structural steel) are often corroded. This paper describes the process (assessment, testing and construction) used to rehabilitate a decades old tower that was experiencing all of the problems identified above. The paper discusses the procedures that were performed to (1) repair cracks in the exterior walls above the waterline, (2) stop leaking cracks on the interior walls below the waterline, (3) line the interior walls with a moisture vapor resistant epoxy and (4) coat the interior steel surfaces.
