Looking through some more photos from 10 years ago we came across these from a rather unique water supply operation at a large, highway construction site in Maryland. The purpose of the operation was dust control and ancillary water use on the site. The large elevated tank was kept full via a fire hydrant connection, a few hundred feet of fire hose, and an automatic shut-off valve. Two large water trucks hauled water as needed and reloaded at the elevated tank using a chain-operated valve. Absent the issue with freezing temperatures, such a design could be used in rural areas as long as some type of water supply exists (a well, a low-flow hydrant, etc).
