Claim:
A portable main drain for a body of water bounded by a sidewall and floor wall, said portable main drain including: a top wall interconnected with a bottom wall by a spacer wall enveloping a volume defining a water manifold; said spacer wall containing a water delivery port and each of said top wall and said bottom wall having water intake ports all communicating with said water manifold; said water intake ports in said bottom wall being dimensioned and arranged to conduct water at a sufficient flow rate for extracting debris from an area of said floor wall surrounding said bottom wall; stand off members projecting from said bottom wall for spacing said water intake ports in said bottom wall above said floor wall of said body of water to impart stability to avoid entrapment of said water intake ports with said floor wall of said body of water; and a conduit joined with an outlet port for conducting water of the body of water from said water manifold for delivery externally to said sidewall.
