Looking at buying a new house but it needs to have a Mound Septic system. Builder went bankrupt and left a few things to be completed. Septic being one of them. Anyone know a good company to use for this?

Boswell's septic 301-645-9549

Wayne's Drains and Septic Service, he's in Mechanicsville. Don't have the number handy, but he's in the yellow book.
