Respondent city acquired title, August 1, 1898, to the water system of the Duluth Gas & Water Company, and has owned and operated it ever since. The present city charter went into effect March 8, 1900, by which there was created a board of water and light commissioners. The board formulated r.ules and regulations in reference to the use of meters, and for consumers of water in private residences published a fiat rate of so much per month, based on the number of bowls, tubs, and closets, and concerning the use of meters rule 6 was adopted, which reads:
“Meters may be placed upon any water service at the wish of the owner or occupant of the premises, or at the pleasure of the *57board, and in both cases the board will furnish the meter and set the same at the expense of the consumer, reserving the right to inspect it and remove it for tests or repairs. Under special circumstances the board may furnish and set meters at its own expense, charging rental therefor. All persons .are forbidden to interfere with or remove a water or gas meter from any service where it has been attached, without first receiving permission from the board.”
In September, 1901, the meter in appellants’ premises, a private residence, having become out of order, was taken out by the commissioners for the purpose of repair, and at or about that time appellants made application to be furnished water at the then established flat rate, and requested that the meter be not replaced. The application was denied, and the commissioners insisted upon replacing the meter, wh'eia appellants refused to permit its installation, and the city threatened to cut off the water, whereupon this action was commenced for the purpose of restraining and enjoining the commissioners from replacing the meter and from cutting off the water supply, and to require the city to furnish the premises with water at the established flat rate.
The trial court found the facts as stated, and in addition thereto found that rule 6, above quoted, was the only by-law, regulation, or ordinance adopted by the board relative to supplying consumers with water at a flat or meter rate, but that in practice the board permitted any prospective consumer applying for water in the first instance a choice of flat or meter rates, making it a condition, however, that if the meter rate is adopted it cannot thereafter be changed to a flat rate without the consent of the board. The court also found that the flat rates were made, as nearly as possible, uniform with the meter rates, allowance being made for the greater waste thought to exist when water is taken at a flat rate; that water is furnished to consumers as nearly as may be at the cost thereof to the city, and that water is furnished for sprinkling lawns when consumers are taking-under the flat rate at one cent per square yard for the season, but to meter consumers at the regular meter rates; that appellants had about three hundred square yards of lawn requiring water, which respondents furnished during the sprinkling season. The court also found that prior to Jan*58uary 1, 1901, while appellants were paying for water at meter rates, the amount consumed cost less than they would have paid at the fiat rate, but that from January 1 to September 1, 1901, appellants had paid about fifty to fifty-five cents per month more at the meter rate than would have been chárged at the then established flat rate. It is also found as a fact that about three-fifths of the families in the city using water paid for it at meter rates, and that in dealing with appellants the board did not treat them differently than other consumers of water similarly situated.
In support of the appeal the following propositions are submitted: That water rates are taxes, and there can be but one method of determining the rates, which must be reasonable and uniform; that appellants had the option of taking water upon either the meter or flat rate basis, and that in refusing them the flat rate system the board discriminated against them and prohibited the use of privileges permitted to other consumers.
1. Water rates are not taxes, within the meaning of those constitutional provisions which require a uniformity of taxation. Section 178 of the city charter provides for a levy of not less than one-half mill, nor more than one-and-a-half mills, on the dollar annually on assessed valuations of the taxable property of the city, to be paid into the treasury to the account of the board of water and light commissioners for the purpose of reducing the water rates to consumers, but this provision has nothing to do with the price to be charged for water by actual consumers. The burden designed by section 178 is assumed by the city upon the theory that it is for the benefit of the .people at large to support a municipal water plant. ' Such a system is to the city’s advantage, and of benefit to all property owners and taxpayers. The power conferred by the charter upon the city of Duluth to own and maintain its own water system is in its nature public, because conferred for the public benefit, but in another sense the powers conferred may be considered private, because they are such as may be, and often are, conferred upon private individuals or corporations. See Dillon, Mun. Corp. § 27.
Taxes are the enforced proportional contribution from persons and ' property levied by the state, by virtue of its sovereignty, for the support of government and for all public needs, and they are therefore properly *59subjected to the rule of uniformity. But water rates are imposed and_ collected merely as the compensation or equivalent to be paid by those who choose to receive and use the water. Water rates are in no sense taxes, but merely the price paid for water as a commodity. The principle of the distinction is very simple. In reference to taxes there is no choice. The burden falls alike upon all property, and should consequently be equal as nearly as may be, but in the case of water rates the relation of the city to the consumer is that of contract. The city has no power to compel any person to buy water, and, for the reasons above stated, the question of the amount of the rates depends not upon the principle of uniformity, or equality between the various consumers, within the principles of taxation. Wagner v. City, 146 Ill. 139, 154, 34 N. E. 545; Silkman v. Board, 152 N. Y. 327, 46 N. E. 612; Jones v. Board, 34 Mich. 273. It follows that a uniform system of rates applicable upon the same basis to all consumers is not within the requirements of the charter.
2. According to the findings of the court it has been the policy of the water commissioners to make the flat and meter rates as nearly equal as possible. The only accurate method for .the measurement of water is by meter. Experience shows that consumers paying at the flat rate waste a certain amount of water, which the board take into consideration in fixing those rates, and, according to the evidence, the rates are adjusted from time to time to meet this fact in accordance with the knowledge gained by experience. The city acquired its plant from its predecessor, the Duluth Gas & Water Company, and took the’ conditions as it found them, and at that time both systems were in effect. In furtherance of the board’s purpose to furnish water at the least possible cost to consumers, and at the same time to gradually approach a universal use of the meter system, rule 6 was adopted. The board did not at once require all consumers to use a meter, but rather adopted the practice of requiring those having meters to retain them and pay for the amount of water actually consumed.
The only ground upon which appellants can assail the act of 'the commissioners in refusing to place them upon the flat rate basis is that it resulted in a discrimination between them and other consumers who pay at flat rates, or that the meter rates were unreasonable; but according to the evidence and the findings, the meter rates were reasonable. *60If it appeared that other consumers upon the flat rate system had an advantage and were enjoying a privilege not accorded those using meters, and that the commissioners were arbitrarily making such discrimination,, there might be some ground for complaint. But such is not the case. On the contrary, the evidence and findings are to the effect that a large-majority of those using meters save money by so doing. The fact that according to appellants’ experience with a meter prior to the time it was taken out showed their water bills to he more than according to-the flat rate, does not establish discrimination, nor prove that the rate-by the meter is unreasonable. It is found by the court that all consumers situated as appellants have been similarly treated, and it does not appear that the method adopted by the board to gradually bring consumers upon the meter basis is illegal or arbitrary, or that it resulted in discrimination. The city, through its board of water commissioners, has a reasonable discretion to accomplish what the charter authorizes. See Parker v. City, 1 Allen, 361; State v. Gosnell, 116 Wis. 606; Sheward v. Citizens, 90 Cal. 635, 27 Pac. 439.
