When the permanent water supply from the Gunpowder Falls was built, it included a dam at Loch Raven, a 12′ tunnel approximately 7 miles long, an impounding reservoir at Montebello, another conduit from there to Lake Clifton and then it was distributed to the public as unfiltered, yet wholesome drinking water.

How the gate house area looked in 2011.
When they eventually removed the gate house, they kept some of the original stone and built this somewhat mini-monument to the Permanent Supply, across the street.
The supply is finished and the valves are opened. This is downtown Baltimore at the Battle Monument. Caption reads: Fountain and Cataract – Monument Square – The Introduction of the Gunpowder Water Supply – Oct. 10th 1881
Water and Me 
Hi!
I was wondering if you may have any information about how the city detects leaks in pipes that are located in old concrete? I am researching the sinkhole over on Mulberry.
Thank you!
Back on Dec 8th I posted about one of the ways it is done. Using what is called a pipe diver. Mostly it is by acoustics. Pipe outside the plant where I work is another agency. We mostly concern ourselves with process (filtration). I do know that the pipes are very old, a lot of which were put in long before the water was filtered (1915).
Thank you for your response! I tried to find that article, you referenced, but I can’t locate it.
I did stumble upon the fluoride. I have to read it!!!
Here is the link:

Oh no! Fluoride! The reason I haven’t drank the water in 35 years!
