The Gallinas Diversion Structure project is a rehabilitation of an existing water diversion structure built on the Rio Gallinas northwest of the City of Las Vegas.
The City of Las Vegas obtains approximately 90% of its drinking water from the Gallinas River and was in desperate need of a new facility to provide an adequate drinking water supply with safe access and easier maintenance. The primary objectives of the project were to provide a dependable diversion from the Gallinas River for drinking water, provide a structure with reduced Operation and Maintenance costs, and provide the ability to install a Supervisory Control and Data Acquisition (SCADA) system in the future.
