delivered the opinion of the court:
The sole question is as to the right of appellee to recover the sum thus paid under protest. It is not claimed that the city had any lien on the lots for the back taxes or that appellee was under any obligation to pay the same, but it is claimed by appellant that the city had a right to say that it would not furnish a future supply of water unless its old bills were paid, and that the payments were made by appellee with full knowledge of all the facts, and were therefore voluntary and not under protest, and cannot be recovered.
Appellant is a municipal corporation. Its corporate powers do not require it to furnish water to its inhabitants, but it has the right so to do when it sees fit. But when it does thus furnish its inhabitants with water, it is not by virtue of the exercise of the power of sovereignty, but it is a business which is public in its nature, and belongs to that class of occupations or enterprises upon which public interest is impressed. The water rates are imposed and collected, not as a tax, but as a compensation to be paid by those who choose to receive and use the water. The city cannot arbitrarily establish its rates, but they must be, to a certain extent, uniform, reasonable and just. Neither can the city arbitrarily select its patrons, but it must serve all who may apply on equal terms. (Wagner v. City of Rock Island,
Complaint is made that the court allowed interest on the various amounts from the date of payment by appellee to the date judgment was rendered. We do not think there was any error, for the reason that appellant wrongfully took from appellee the sum of $1564.94 and had it in its possession from that time until the present. As a general rule, a municipal corporation is not liable for interest unless so required by special contract or by statute, but in case where a municipal- corporation wrongfully exacts money and holds that money without just right or claim, it is liable for interest on the same. Vider v. City of Chicago,
We find no reversible error, and the judgment will be affirmed.
Judgment affirmed.
