We have two 2500 tanks (in different locations) on sand.

I got these from local.yahoo.com searching for "rainwater".

I have purchased a 2500 gallon and a 550 gallon water tank from a friend.
He never did anything with them so I an uncertain about the base.

I read about concrete base but I also read that a sand or pea-gravel base
will work just as well.

Does anyone know someone who is in this business? I believe I would just as
soon contract this out.

thanks
