These are two actions of tort for damages to the personal and real property of the plaintiffs caused by the alleged negligence of the defendant city in the construction and operation of a water main or pipe in front of the plaintiffs’ premises. The Lowell Trust Company occupied the first floor, part of the basement, and certain rooms on the second floor of the brick building owned by the plaintiff Lyons. At a point about thirty-five feet from the entrance to the banking house of the Lowell Trust Company, the Middlesex Street water main connected with the one in Central Street, both mains being twelve inch pipes. At or near the point of intersection a break occurred, the water rising five or six inches above the level of the street and causing damage to the plaintiffs’ property. The cases were referred to an auditor, under an agreement that his findings of facts were to be final. It was also agreed that the water mains were a part of the defendant’s water department, and were for the purpose of supplying water to its inhabitants, for pay; and for use in its fire department and supplying drinking fountains, for which no revenue was received.
The auditor found that the break was in the bottom of the Middlesex Street water main near a “ stone or piece of ledge . . . imbedded in the gravel underneath the line of this water main;” *312that the adjacent parts of the main rested on dirt or gravel; that the break was directly caused by the negligence of the defendant in the original construction and location of the pipe, by placing it in such close contact with the ledge or stone without a sufficient amount of sand or gravel or other support underneath the pipe and between it and the ledge; that the pressure from above tended to cause a “ buckling or breaking of that part at that resting point, and the break would take place in the bottom of the water main, as in fact did occur.”
The city in furnishing water to its inhabitants for its own profit was engaged in an undertaking commercial in character and was liable for its negligent acts. Lynch v. Springfield, 174 Mass. 430. Bolster v. Lawrence, 225 Mass. 387. As the city has been found by the auditor to have been negligent and as his findings by the agreement of the parties are final, judgment was entered properly for the plaintiffs. See Daley v. Legate, 169 Mass. 257,259,260. The record does not show that the defendant’s requests for findings of fact were improperly dealt with by the auditor, Weld v. Brooks, 152 Mass. 297, and even if the defendant was careful in the inspection and testing of its water pipes and mains, the fault as found by the auditor was in the original .construction, — that if proper care had been used when the pipes were laid the break would not have occurred.
The findings for the plaintiffs were warranted. Judgment is to be entered for the plaintiff Lyons in the sum of $1,729.26 and interest from the date of the writ, and for the plaintiff Lowell Trust Company in the sum of $2,562.45 and interest from the date of the writ.
So ordered.
