Y--Orpi-240821 - Replace Primary Park Water System for Maintenance and Housing Area

Replace the Parks Primary Water System will restore various components related to the domestic and fire protection water distribution system within Organ Pipe National Park to address various system deficiencies. The existing system was constructed using asbestos-cement (AC) pipe. Some sections of the pipe have been replaced over the years since, but approximately 5500 linear feet of this pipe remains in service. The AC pipe frequently fails as rubber gasketed joints become brittle leading to points of leakage. Failure of these joints have drained the Park’s 100,000-gallon water storage tank. The two water storage tanks have also exceeded their life expectancy and have deteriorated due to the mineral content of the water. A supply well is producing at levels unacceptable to the park’s needs, and fire-fighting capabilities are compromised with less than sufficient fire flow to the existing hydrants. One of the Park’s two water wells (north well) is being replaced by a separate project. This project will replace the south well. The south well has deteriorated to an unacceptable level to maintain adequate water supplies for the Park. Degradation of the casing is occurring and iron deposits from oxidation are sealing perforations in the casing. Static water levels have dropped in recent years making the amount of available water less than desired levels. Water consumption has increased steadily as the park sees more and more visitors annually. The documented lower water table necessitates the need to drill a deeper well to maintain these services at expected levels. The goals of this project are to provide Organ Pipe National Park with reliable water systems which will meet or exceed flow capacity requirements for domestic water and fire protection for years to come, allow staff to streamline the monitoring and oversight of these systems and significantly reduce service disruptions and operation and maintenance costs.
