Two projects are slated for 2010 at the Galleries Water Tank. The primary work associated with the first project will replace a failing roof and improve security. The second project will be the installation of an interior liner.
Salida’s Gallery Water System consists of an infiltration gallery, chlorination system and a 1.25 million gallon water tank. The water tank is a cast in place rectangular shaped concrete tank. It is partially buried with the upper four feet exposed. The existing roof of the tank is a 38-year old built up roof (BUR) covering. A BUR is a class of low-slope roof that consists of layers of reinforcing felt sandwiched between coal tar bitumen. The top layer is covered with gravel. A contract to completely remove and replace the BUR was awarded in March 2010.
In addition, the concrete interior of the tank is experiencing leakage problems. A liner attached to the concrete interior will solve the problem. A solicitation for bids to install the liner will be published in early mid 2010 with work to be completed in early fall.
This project is funded through a low interest rate loan from the Colorado Water Resources and Power Development Authority.
