We used Archers about three years ago to empty our tank - was about $275.00, and is a 500 gallon tank. We generally use Bud Light and BBQ to refill it - pricing varies....
I just had a major problem over the 4th. Alabama Waste Water Mgt came right out and did our pumping and repair. Daniel and his father Danny have been in business for over 30 years and you will not meet a better bunch of guys. 256-397-0260 or 256-329-2576. It was pouring rain when they showed up, when they said they would, and not one complaint and worked right through. Call them.
