Park City officials recently posted a sign on the Masonic water tank off the Aerie warning against trespassing, a response to numerous cases this spring involving people climbing atop the facility or hanging out nearby.
The sign also indicates people should stay on the trails. It says the water tank is under video surveillance. The sign carries the City Hall logo.
There has been a series of reports since late March of people being seen on the tank. They are there for the panoramic views, officials have said. The location offers views of Old Town, Park City Mountain Resort and Deer Valley Resort.
The Masonic tank is easily reachable from a trail. The site is located off Mellow Mountain Road. It is a sensitive facility, though, since it is part of the municipal drinking-water system. People spotted there are trespassing, the police say.
The Masonic tank has a storage capacity of 500,000 gallons of water and serves as a backup source for lower Deer Valley, the Park City Water Department has said. Water can also be sent to Prospector, Park Meadows, lower Old Town and the Park City Mountain Resort area, according to the Water Department.
The warning sign has not deterred everyone. The Park City Police Department last week logged a series of cases at the site. They included:
City Hall's water manager, Clint McAffee, said recently he is aware of one successful unauthorized opening of the tank's hatch, in 2013. The police arrived minutes later but did not find anyone. McAffee said tests found the water had not been tainted.
