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.
