Sonora was incorporated as a city in 1851.
The Gold Mount Water Company was incorporated in March, 1854, and built a system that began operating shortly thereafter by pumping water using a steam engine to the top of Gold Mount, where it distributed to the city.
The Gold Mountain Water Company was incorporated in 1900 and appears to have taken over the earlier water system, although no evidence has been found to confirm that. The new company was sold to the Sierra and San Francisco Power Company in 1912 for $27,500, which became part of the Pacific Gas and Electric Company. Most of the system was sold to Tuolumne County in 1983. The system was incorporated into the new Tuolumne Utilities District in 1992.
Water is provided by the Tuolumne Utilities District.

The workman are steadily engaged laying the pipes, and it is estimated that the water will be flowing through them within two week from this date.

The Sonora Herald thus speaks of these works, which are nearly completed:
We consider this to be the greatest improvement to Sonora that ever has, or perhaps, ever will be introduced. It not only supplies one of the greatest wants of our citizens, but also is the best safeguard against fire it is possible for us to have.
The spring from which they take the ater is situated in about the middle of Holden's garden, at the north end of the city, and is any feet below the level of Washington street. It is the largest and best spring anywhere in this vicinity.
The water is led in iron pipes to Wood's Creek, at the foot of Gold Mount, where an engine is placed to raise it some eight or a hundred feet up the Mount so as to bring it up above the level of all the houses in Washington and adjoining streets. l When it arrives at the height required, it is conducted in pipes ready laid to receive it into the reservoir back of the United States Hotel, from when it is taken down again to the level of Washington street.
The reservoir is a first class piece of work. It is excavated out of solid rock, to a depth of from ten to fifteen feet, and is spacious and roomy. The lower side is called up with slabs of slate, and then cemented all over. The earth on the upper side is prevened from caving into the reservoir by a wall of stout timber, by which means no dirt or filth is allowed to mix in the water or defile it. The water retains its original coldness and purity to an extent hardly credible.

Water for Sonora," Sacramento Daily Union, December 1, 1857,
An additional supply of water is contemplated for the town of Sonora, though the assistance of the Gold Mount Water Company. This company is in negotiation with the Columbia and Stanislaus River Company, for a quantity of pure fresh water equal to that required to fill a reservoir of the same capacity as the one now in use. The Sonora Herald of Nov. 28th, adds:
It may be well to state that this company has a contract with the city of Sonora, to last ten years from some time in the year 1853, to introduce water within the corporate limits of the city. The terms of the contract grant them the exclusive privilege of laying pipes in the streets for this purpose, in consideration of their furnishing gratis, sufficient water to extinguish fires. Their reservoir, on Gold Mount, will contain seventy thousand gallons of water. The quantity of water used in the city has so increased, within the last year, that the company find it necessary to keep the engine and pump used for raising the water from Holden's Garden, in operation, whereas formerly the demand required that they should only keep at work in daytime. The quantity of water used in Sonora now is twice as much as was consumed a year ago.
