. That's the one that can do both. Dozers have the big blades and tracks. most don't have a lot of ability to add attachments.
I haven't heard of that kind of lid, which doesn't mean it isn't an option, but I don't really see the benefit in paying more for it... You still need to have an engineer sign off on the whole system for your permits, which entails their inspections and designing for the substrate/ground. Be sure you don't make the common mistake of thinking that just because they say they dig cesspools, they know what they are talking about. Unless they are licensed, there are tons of yahoos around here with a machine who say they can dig your hole and you get stuck with an expensive mess. I've seen it happen an incredible amount in Puna.
