We source our water directly from the county and flow our sewer to the municipality, we have no well/lift station/treatment plant or any chemicals.

I am much harsher in my feelings.

thanks, Stephen i started it just hours ago and am going the poured-concrete route.put a bulkhead (shower drain) in the middle already of the framed 'pan' with 3" recycled abs leading to my garden irrigation channels.pretty much the only chemicals that will get added to the grey water will be very dilute antibacterial bar soap and the occasional leak while showering that cant wait after a few beers gardening under hot socal sun so hopefully the system's ecofriendly to.

You're talking about hazardous chemicals and potentially dangerous cutting.

If they have to bring cleaning chemicals, vacuum cleaner, paper towels, trash bags, then expect to pay more.

If you burn it, or heat it to over 1100*F (using a heat gun to peel paint or remove wallpaper), it releases a chemical that will cause brain swelling and that brain swelling can cause brain damage or death. 

Superpaint and/or Duration are good unless you need something to fill in cracks, then you can move into something more commercial-grade, like an elastomeric, block filler or even epoxy if that is the look you want but, careful, the thicker and more commercial the product, the tougher it is to get off if needed in the future and anything not water based, be prepared to toss out or clean with a chemical and not ever use it for a water based product again.  

NOTE:  with the oil base primer, make sure whoever is applying has sufficient ventilation in place--I've seen plenty of painters get 'loopy' from the chemicals without proper air change ventilation.

OR, you could call in a mold remidiation team with hazardous chemical suits and pay them $10,000 to do the same thing.

Meth leaves a chemical residue behind that will seep into walls, so you'll have to use something pretty strong, and wear respiratory and skin (gloves, sleeves and goggles) protection.
