Hmm. I would rent a pump and keep evacuating the water before the pour.
If you're going to have an inspection, they'll want the holes free of standing
water too.
Keeping the concrete damp (and cool) slows the cure while increasing the
ultimate strength so once the concrete is poured, the water is a non-issue.
