ABSTRACT:
A wet well pumping system and a method of installing and servicing the same in a wet well include mounting a pair of bent elbows having pump inlets and riser outlets on an alignment platform having a centerline, configuring the riser outlets to extend along longitudinal axes generally parallel to, and located at substantially equal distances from, the centerline of the platform, overlying the wet well with an alignment cover having a centerline and a pair of riser clearance holes, configuring the riser clearance holes to extend through the cover at the substantially equal distances from the centerline of the cover, passing a pair of upright risers through the riser clearance holes along longitudinal axes generally parallel to the centerline of the cover, aligning the longitudinal axes of the risers with the longitudinal axes of the riser outlets, connecting the risers to the aligned riser outlets, securing the platform to a floor of the well after the risers are connected to the aligned riser outlets, connecting a pair of submersible pumps inside the well to the pump inlets of the bent elbows, and pumping waste water from the well though the bent elbows and the risers to outside the well.
