A thirty inch water pipe of the cityjn Tremont Street burst on January 3, 1910; and the plaintiff seeks to recover for property damage resulting therefrom. There was evidence that the break was due to carelessness in construction, especially in failing to support the pipes by proper bearings at places where two lengths were joined. Originally the section was laid in the middle of Tremont Street, and was changed to the easterly side of the street after the subway was built in or about 1897. The controlling question is whether the responsibility for negligence in the laying of this pipe rests upon the city or upon the Boston Transit Commission.
According to the record all water pipes in Boston are laid by the city itself, which owns and operates the system of waterworks. By St. 1894, c. 548, thé transit commission was authorized, among other things, to construct a subway through and under Tremont Street for railway purposes. Section 36 of the. act pro*503vided that the commission might order the removal or relocation of any pipes which it deemed to interfere with the construction or operation of the subway; and the person or corporation owning the pipes was compelled to “comply with said orders.” The record in this case is meagre, but presumably the water pipes in Tremont Street were relocated under the provisions of this statute. The commission might have done the work of reconstruction at the expense of the city if the latter had refused to remove its pipes after notice to do so. Crocker v. Boston Electric Light Co. 180 Mass. 516. See St. 1902, c. 534, § 9. But there is no evidence of such refusal here. On the contrary it appears from the exceptions that the water pipes were moved and relaid by the city, and not by the commission. It does not appear that the commission or its agents or employees took any part in directing or performing the work of relaying the pipes. And when the witness Hannon, on cross-examination, answered “Yes” to the question “under the orders of the transit commission?” it could be found that he meant only that orders to remove the water pipes were given to the city by the commission in accordance with the provisions of said § 36. The unexplained statement of Hannon that the work done by the city would be charged to the transit commission at the most was some evidence in the defendant’s favor.
The plaintiff was entitled to go to the jury on the question whether the work of relaying the pipes was in fact done by the city, and on its own account. The defendant is liable for damages resulting from the negligent performance of that work, on the same principles and to the same extent as a private corporation would be answerable under like circumstances. In constructing and maintaining its water works and distributing pipes the city is voluntarily carrying on a business for which it receives compensation, and it is acting in its private and corporate capacity, not as a public agency of the State.
