ABSTRACT:
A partially buried pumping or lift station including a below ground wet well covered by a well cap and a partially buried pumping unit having an above-ground, removable cover by which access to above-ground pumps is provided. The enclosure sits atop the wet well cap and includes a wall section extending substantially vertically that is sealingly engageable by the removable cover. The cover is raisable by a jack mechanism that includes a hub assembly attached to the cover which allows the cover to be rotated about a vertical axis. The axis is located near a perimeter region of the wall section. The eccentric mounting of the cover allows the cover to be rotated to a retracted position at which it substantially completely exposes the interior of the enclosure. In an alternate embodiment, the cover is mounted to a trackway which supports the cover for rectilinear transverse movement. Vents provide ventilation air into the enclosure and are configured to restrict the inflow of flood waters into the enclosure during flood conditions to an amount that can be pumped from the station by the pumps as long as power is maintained. In the disclosed arrangement, the vents include fluid responsive valves which close when flood waters attempt to enter the vents thereby substantially restricting the flow of flood waters into the enclosure.
