ABSTRACT:
An underground storage tank for use for wastewater storage or as a temporary holding tank for wastewater or runoff from drainage systems. The present holding tank includes a generally cylindrical sidewall having a plurality of integrally molded longitudinal and annular reinforcing ribs spaced circumferentially about the sidewall. The ribs greatly strengthen the sidewall against the crushing forces of hydrostatic pressure, and thus the present tank can be constructed from polyethylene. The bottom of the tank terminates in a tapered portion having a plurality of integrally molded reinforced support posts, each of which terminates in a ground support pad. A raised anti-flotation annular collar separates the tapered portion from the main body of the tank and prevents the tank from being lifted by hydrostatic pressure.
