Abstract
A system for and method to control and improve throughput of liquid in a sewer system utilizes a generally gas free column of sewer pipes. A single manhole has a separate section to handle waste water and a separate section to handle surface water, with pipes operatively connected to them. Valves connected to the manhole and pipes are opened and closed to prevent outlet as well as to prevent gas from entering the outlet to keep the sewer pipes filled with liquid, and fluid travels pipe-in-pipe and forms a gravity flow high capacity (full current) column.
