Abstract
A laminar flow collar for use with an effluent pump in a septic system. The laminar flow collar is a cylinder having a closed bottom and an open top portion. The laminar flow collar includes a plurality of holes drilled about the periphery of the cylinder at a certain distance from the bottom. The laminar flow collar sits on the bottom of the tank and the plurality of holes are positioned at a certain height from the bottom of the septic tank and below the surface of the effluent so as not to draw in “scum” floating on the top of the septic tank. The plurality of holes are engineered to match the pump flow so that flow into the collar is laminar, thereby avoiding turbulence in the tank which would otherwise stir up the sludge at the bottom of the tank. The effluent pump is inserted into a second cylinder which is placed within the laminar flow collar.
