Waste water electrical power generating system

An environmental protective electrical power generating system is formed by a penstock connected at its opposite ends to a large sewer for conveying waste water from feeder pipelines to a sanitary treatment station.

The turbines are operatively connected to electrical power generators for producing electrical power and dispersing the power through an electrical power transmission system. Depending upon the size of the sewer pipes, the volume of liquid flowing there-through, and the turbine and generator equipment, electrical power is generated without affecting the environment or ecology and without the use of fossil fuels.
