This existing system is composed of two existing water wells and two existing water reserve tanks. The existing water well system is located along road PR191, starting from Yokahu tower (Km. 8.9 approx.) and ending approximately at Km 12.7.

The Palo Colorado water well is located at PR-9938 km .1, and the Caimitillo water well is located at PR-191 km 11.8. The tanks are found at two different locations, approximately 700 ft. from each other. The production rate of the existing Palo Colorado and Caimitillo water wells is around 20 gpm. The existing Caimitillo Water Tank is located along the Caimitillo trail, approximately 500 ft. from the trailhead at road PR191,

km. 11.7. The existing Palo Colorado water tank is located along the Baño de Oro trail, approximately 900 ft. from the trailhead at road PR191, Km. 12.2.
