The East Central region of Puerto Rico, including the municipalities of Gurabo, Juncos, Las Piedras and San Lorenzo, was a rapidly developing area making the water supply in this region scarce, in spite of abundant rainfall and several sources of water supply. The existing water supply, treatment and distribution systems are unable to meet demand with serious water shortages during peak usage periods. As development continues, water demands will continue to rise, creating the need for development of additional water supply. The Valenciano River, located in the Municipality of Juncos, has been identified as a possible source of raw water since 1969. Previous studies indicated that the impoundment of the Rio Valenciano would provide a cost-effective solution to supply water to the region. The purpose of this project is to facilitate the implementation of the required action to meet the regional water needs. CSA assisted with acquisition and development of the program to provide a storage solution.

The project includes construction of a new dam and reservoir along the Rio Valenciano. The new reservoir inundates approximately 554 acres. The Valenciano reservoir has a drainage area of approximately 14.5 square miles.

The College of Engineers & Land Surveyors of Puerto Rico gave this project an Outstanding Surveying Project award. The surveying and geospatial data was gathered from a wide array of sources over the last four decades due to various postponements. This significant effort included integrating the information from multiple coordinates systems, datums, technologies, and methods.
