Abstract (en)
[origin: WO8304425A1] A hydroelectric generator (52) is located in the basement of a high-rise building and connected in series in the clean waste-water line (18) of the building, to produce electrical power in response to the flow of the waste water from the building. An automatically controlled valve (50) in a bypass line serves to direct excess water flow around the hydroelectric generator unit and maintain the flow through the generator unit at a predetermined maximum level. An automatic switch-over device (54) disconnects the generator output terminals from the electrical output terminals of the unit when the voltage and/or frequency of the generator output is unsatisfactory, e.g., too low.
