4LEAF provided inspection services for the Cuyamaca Rancho State Park Water System Rehabilitation Project. Cuyamaca Rancho State Park’s aging water storage and distribution system had exceeded its design life and was experiencing many leaks requiring excessive maintenance to keep the system operational. Water facilities were showing extreme deterioration and if allowed to fail could have caused closure of park campgrounds, residences, and maintenance buildings. A safe dependable supply of potable water is critical for successful park operations. The purpose of this project was to rehabilitate existing water supply reservoirs, wells, distribution and monitoring systems throughout the park. Estimated cost of the restoration was $2 million. The project included rehabilitation of four existing underground potable water storage tanks, construction of one new water storage tank, instillation of a telemetry system at the tanks to allow maintenance staff to monitor water levels readings without having to traverse the park, activation of a new well to increase available water supply, and replacement of undersized and deteriorating water lines.
