An investigation of the practical working of municipal ownership in American cities will show that this danger is not purely imaginary. In the year 1899 53.73 per cent. of the waterworks in this country were owned and operated by municipalities, public ownership being the rule in the larger cities. Taking the thirteen largest plants in the United States, all of which were municipally owned, the income from private users was $20,545,409, while the total cost of production, including estimated depreciation, aggregated only $11,469,732. If to this amount be added the estimated taxes, interest on total investment and rental value of the municipally owned quarters occupied for this purpose, the total cost of production would be $22,827,825. Private consumers, however, used only 80.2 per cent. of the water supplied. If the 19.8 per cent. supplied free for public purposes had been paid for at the same rate charged to private users, the total income from these 13 municipally owned plants would have been $25,817,720. This would have been $2,989,895 in excess of a fair return upon the total investment. No one would claim that the price of water has been increased under municipal ownership. As a matter of fact, it has been substantially reduced and the quality of the water at the same time improved. The reduction in price, however, has been less than it would have been, had the interests of the consumers alone been considered. If the object of municipal ownership is to supply pure water at the lowest possible price to the general public, there is no good reason why the city should demand a profit on the capital it has invested in the business. This would certainly be true where the earnings under municipal ownership have been sufficient to pay for the plant. In this case it would be an injustice to consumers to make them contribute, over and above the cost of operating the plant, an additional amount sufficient to pay interest on the investment, inasmuch as they have supplied the capital with which the business is carried on. Any attempt to make municipal ownership a source of revenue would mean the taxation of water consumers for the benefit of property owners. Nor is there any reason why the private consumers of water should be made to pay for the water used for public purposes. The water needed for public buildings, for cleaning streets and for extinguishing fires ought to be paid for by those chiefly benefited--the property-owning class.
