Whenever, in the judgment of the governing body of any city in the state of Kansas, in the construction, maintenance and operation of its sewer system, whether it be a part of its sanitary sewer system, storm sewer system, or a combination of both, that on account of elevation, dike, or any other reason, it is impracticable, or too expensive, to excavate in connection with such sewer or intercepting sewer with another sewer district, or intercepting sewer, or in order to provide an outlet of any kind for the sewage of such sewer or intercepting sewer district, whether such sewers be sanitary sewers, storm sewers, or a combination of both, the governing body of such city is hereby empowered to construct a pumping station for the purpose of pumping such sewage of such sewer or intercepting sewer to some other sewer district in said city over any elevation, dike or other obstruction in order to conduct the sewage thereof to a point of outlet, whether such outlet be an intercepting sewer, another main sewer district, a sewage disposal plant, or a stream.
