I checked our installation price list and the pre-plumbed option is $4000 for grey and black water plumbing in addition to hot/cold plumbing with a hot water heater.

Had a black water back up.

Only way I'd do it is if I could JV with Blackwater.

The carpet was stained like someone walked around spilling who knows what and never bothered to wash it up, very dirty dirty walls, black water in the toilet, screens busted out of the screen doors, the fridge was new but you about died when you opened it from the smell of rotting food...you get the picture.

('cept maybe Halliburton, KBR, exxon, blackwater, etc.)

They are responsible for maintaining the black water drain.

Since it was black water pretty much all of the flooring in the unit and the vanity in the bathroom had to be ripped up.  

Refigeration can be an issue, three dump sink, grease trap, gray/blackwater holding, screens over lights, fire suppression if you have fryers or stoves.

Sewage and even a kitchen sink with a garage disposal is considered black water and needs special clean up with disinfectant and a sterilizer.

It used to be called black water, and sources include sewer backup, flooding from rivers or streams, toilet overflow with feces, and stagnant liquid that has begun to support bacterial growth.Next are the classes of destruction.• Class 1.
