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.
CROSS-REFERENCE TO RELATED APPLICATION
This application is a continuation of prior copending U.S. patent application Ser. No. 09/951,662, filed on Sep. 10, 2001, now U.S. Pat. No. 6,644,342, which is incorporated herein by reference.
A cover assembly for covering a vessel comprising a main cover comprising at least a first outlet opening adapted for connection to a pipe, and a second opening surrounded by a flat region adapted for placement of a gasket; an access cover comprising a flat region adapted for mating with the flat region of the main cover; and provisions for the sealing of at least one cord passing between the main cover and the access cover. In other embodiments, the cover assembly is provided with an engagement feature adapted for engagement with a hook-shaped hanger rod. Sewage basin assemblies are also provided which incorporate these cover assemblies.
A cover assembly for a lift station is disclosed. The cover assembly includes a cover in which an access opening, a cable passageway and a vent are defined. The cable passageway has one end that connects to the access opening and another end that opens to an exterior of the lift station. The cable passageway and the access opening are covered by hatches that can be opened to fully uncover the cable passageway and a portion of the access opening adjacent the cable passageway. This facilitates installation and maintenance of cables running between external equipment and internal equipment. The hatch covering the cable passageway is substantially solid to prevent venting of flammable gases. An interior of the cable passageway has an additional barrier to these gases. The vent is spaced apart from the cable passageway to further separate the cable passageway and external equipment from flammable gases.
