If you live in an area where there are a lot of sand/gravel aggregates and little clay, a gravel pit type excavated pond might be not only the least expensive choice, but also the only choice.

I would be trying to find out the depth of the water table where you are at and how deep the sand company will likely excavate to (they may not know this until they actually take your sand out, but perhaps you could learn the maximum depth there equipment is capable of going), to guess at how deep your pond could be.

Perhaps a contract with the sand company should include an end condition that is either a gravel pit pond or a reclaimed hole (topsoil spread back over it) - your call, depending on how deep they end up going wrt the water table depth.
