Dennis, Look in your yellow pages under plumbing or sewers or septic systems. Also check with your pumping co. they can advise you as where to go. Find a distributor or a supplier, they can help you. also whats new is a plastic type of tank as well as the concrete tank which costs more to install than the plastic version. Price out both. By the way I can't believe a home inspector did not indicate to you that the septic tank should have been opened up and pumped for a good visual inspection and possibably instructed you to get a perk test to see if the ground would perk. At least advise you after all why else would you hire him except for his expert advice. good luck, brAin
