So what does a tank cover do? The manual from the state really advocated having a solid cover,

I talked to the guy at Island Catchment about a solid tank cover, and the short answer is that a solid tank cover costs more than the tank does. The long answer is that there is no standardization on tank sizes so nobody manufacturers a pre-fab "kit" which would make the price reasonable. Also that if it's a solid tank cover that sits on the tank, the way they are braced puts an outward pressure on the tank which it's not designed for, so the tank itself requires reinforcement so it doesn't burst open. There was a guy down in South Point who's house was knocked off it's post and piers when his tank failed and the wall of water hit his house (I don't know if has anything to do with a tank cover but it illustrates the dangers of the tanks bursting). A friend of mine (also in South Point) had his tank burst open too, but fortunately the side that burst was facing away from his house.
