Abstract
A modular well for a wastewater lift station includes multiple well sections. Each of the well sections has at least one mating feature allowing it to be joined to at least one other well section and to form a liquid tight seal. The well is formed by vertically mating the well sections together. One of the well sections has an inlet opening, and the same or a different well section has at least one outlet opening.
Claims22
A modular well for a wastewater lift station, the well comprising:
- multiple well sections, the multiple well sections including at least a bottom well section having an upper end with a two-step rim, at least one intermediate well section having a lower end with a two-step lip and an upper end having a two-step rim, and a top well section having a lower end with a two-step lip,
- each of the well sections being matable to allow one well section to be joined to another well section to form a fluid tight seal between the joined well sections,
- a first one of the well sections having a side wall in which an inlet opening is defined, and the first or a second one of the well sections having a side wall in which at least one outlet opening is defined,
- wherein, in the assembled well, the at least one intermediate well section is vertically joined with the bottom section, and the top section is vertically joined with the at least one intermediate section.

A kit for a modular wastewater lift station, comprising:
- a plurality of precast concrete well sections, including:
- a bottom sump well section having a rectangular lower end with a protruding exterior edge, a substantially cylindrical outer surface above the lower end, and an upper end with a two-step lip, the bottom sump section having an inner surface defining an inverted generally frustoconical shape and a self-cleaning insert,
- 2+N substantially cylindrical intermediate sections, with a whole number N being determined by a desired depth of the well, the intermediate sections being tubular and having a lower end with a two-step lip and an upper end with a two-step rim, a first intermediate section having an inlet opening and a second intermediate section having two outlet openings, the first intermediate well section being matable with the bottom sump well section and the second intermediate well section being matable with the first intermediate well section,
- a substantially cylindrical top cover well section that serves as the well cover, the top cover well section having a lower end with a two-step lip shaped to engage the upper end of the second intermediate well section, the top well section having a pre-formed access opening and a pre-formed passage;
- two pumps positionable in the bottom sump section to evacuate wastewater from the assembled well;
- a wastewater inlet pipe positioned to extend through the inlet opening of the well;
- and a wastewater outlet pipe leading from the two pumps upwardly and through the outlet openings to a downstream location.
