delivered the opinion of the court.

The eases were argued and submitted together, and involve substantially the same question, to wit, whether the railway company is liable for the foul and unsanitary condition of certain syphons or catch basins connected with culverts constructed by it, under the direction of the city.

The facts out of which the controversy arose are undisputed, and substantially as follows : The defendant company is a corporation organized under the laws of Colorado, and operating street railways in the city of Denver, under and by virtue of a franchise granted by ordinance 36 of the series of 1888, sections 8 and 9 of which are as follows:

“ Sec. 8. That The Denver City Cable Railway Company, Its successors* and-assigns, shall* construct culverts -in such manner and at such points on its lines as the city council shall require and designate.”

“Sec. 9. The city council hereby reserves the right to pass any ordinance with reference to the operation of' said cable railway which the comfort of the inhabitants of said city, or the safety of passengers upon said railway may require, reserving also the police and legislative powers and functions with respect to the streets and avenues that may be used and occupied by said railway.”

in compliance with the requirements of section 8, the Railway Company constructed permanent culverts passing *568under the surface of the street, and under its railway tracks, which terminate at each end in a syphon or catch basin, as required and designated by the city authorities. These syphons, located at each end of the culverts, consist of round or- well-like receptacles, whose bottoms are considerably below the bed of the culverts. On account of their construction, the surface water passing along the gutters would necessarily fill that portion of the catch basin below the level of the culvert before it would pass off through the culvert ; and the sediment, débris and washings from the street, being of greater specific gravity than the water, would settle in the bottom of these basins, and in the course of time become decomposed and unsanitary; and while the culvei-ts were entirely sufficient to carry off the water passing into these syphons, yet the syphons themselves, unless cleaned out, would become filled with foul and unclean matter. It is admitted that they were in this condition, and that the company had refused to clean them out, at the time these actions were instituted.

It is insisted on behalf of the city that section 2 of ordinance 27, series of 1889, providing that the company shall, at their own expense, “furnish, construct, put in place and maintain * * * all necessary syphons,” etc., is a valid exercise of its police power, and of the right reserved by section 9 of the franchise ordinance of 1888; and imposes upon the company the duty of keeping the syphons clean, as well as of constructing them in the first instance.

On the part of the company it is claimed that the language used in the section is not susceptible of such construction; and if it can be so construed, the ordinance is invalid, because it impairs the obligation of its contract with the citj1-, in that it imposes a new burden upon the company, and one that is in no way connected with the operation of its railway, or within the intendment of the reservation in section 9 of the franchise ordinance.

We think that both of these positions are well taken. The maintenance or existence of these syphons have no reference. *569to, or connection with, the operation of the railway. They are not a part of the company’s property or its system, but are a part of, and incident to, ordinary street improvement, and the defendant in error lias no more interest in them than any other person using the street. Not having assumed the burden as a consideration of its franchise, it therefore follows that the imposition of the duty upon it of keeping these particular syphons clean does not fall within the legitimate exercise of the police power of the city. In so far as the ordinance in question undertakes to impose such new and additional burdens upon the companjq it is invalid; and if we assume that the company constructed the syphons under the direction of the city engineer, under and in accordance with the provisions of the ordinance of 1889, and are therefore estopped from asserting its invalidity, as contended by counsel for plaintiff in error, we still think that the language used therein is not susceptible of the construction contended for by the city, but that the signification to he given to the word “ maintain,” as used in the ordinance and applied to the syphons in question (which are intended to designate the catch basins placed at each end of the culverts, and do not include the culverts or conduits connecting them), is to keep in repair or replace, and does not mean the keeping of them clean and in a sanitary condition, since a failure to keep them in such condition in no way impairs their use or impedes the flow of water through the culverts. In either view, the company is not amenable to the charge preferred in the first case. It necessarily follows that since the syphons complained of are not the property of the defendant, nor in any way connected with the operation of its business, and were not constructed for its use and benefit, and being in no way responsible for their unsanitary condition, the company cannot be held guilty of maintaining a nuisance, and was properly acquitted on the second charge. The judgment of the county court is accordingly affirmed.

Affirmed.
