Beginning Feb. 8, 2022, the first phase of short-term repairs and upgrades to the Phantom Ranch Wastewater Treatment Plant (WWTP) will begin. Work is anticipated to be completed by December 2022 and includes two phases of hauling equipment via helicopters. The first phase is anticipated to go through March, and the second phase is expected to resume in September.
Inner canyon trail users in the vicinity of Phantom Ranch may experience temporary delays of up to 15 minutes, and noise and dust from equipment and helicopters. The contractor, GSE/Coventina Water, LLC, will have limited use of a heavy-lift helicopter (Chinook) to haul supplies and equipment. Visitors should follow directions from National Park Service (NPS) staff and construction crew workers as needed in the work zones to maintain safety.
