Abstract

Disclosed herein is a method for diverting fluid from an upstream pit in a gravity-based fluid conveyance system to a discharge site. The method includes: (i) fluidly connecting an upstream pit and a discharge site, via a pipe, partially inserted into the upstream pit through a top opening of the upstream pit, with a pipe inlet end being submerged in a fluid in the upstream pit, and with a pipe outlet portion, which is U-shaped and comprises a pipe outlet end, being positioned at the discharge site, such that the pipe outlet end is positioned higher than all of the pipe inlet end and a bottom section of the pipe outlet portion is positioned below a fluid surface of the fluid in the upstream pit; and (ii) filling the pipe with fluid.

Abstract

Disclosed herein, are gravity-based sewer bypass systems and related methods for diverting sewage fluid from an upstream sewer pit to a discharge site lower than the upstream sewer pit, via a pipe including an above-ground portion. A sensor external to the pipe is used to determine the sewage fluid level in the upstream sewer pit and accordingly regulate the outflow of sewage fluid at the discharge site.
