Rob Rose,
Look into having a pool filling company bring in a truck. Obviously that costs but at least you will have a flow to keep up.
We use them when well supplied homes can't keep up. It's in the verbiage that the customer pays for it directly (keeps us
out of the transaction).
The tanker trucks are usually 3500-4000gallons
Haven't had to use the tanker trailers yet. (thankfully)
Rod
