If you are having problems with a pink elephant, time to lay off the sauce, buddy.
Let's talk about your white elephant. We can't have these tramping around the Cul de Sac!
You haven't really said what the problem is. Is the drainfield clogged? Is the septic tank not draining? They are supposed to be full of water, they don't work if they aren't.
Why in the world has it taken 2 weeks to get your water hooked up?!!! Call a different septic service company to come out if you are actually having problems. To find a good one, call some of the local plumbing supply houses (not a hardware store, but a contractor supply company) and ask for some recommendations.
The septic company might even diagnose your problem over the phone.
