Black water tank?

[mestrezat]

I’m in need of the name of a company that makes black water tanks. The previous owner had a stainless steel tank configured for black water storage years ago and it’s now worthless due to corrosion. I need to find a manufacturer that can fabricate a new one preferably in plastic or like material. I’ve got the specks for the previous tank as it fits behind the wall in the head.

Ronco Tank.They make OEM plastic tanks for many boat builders and kept the molds for all. They have hundreds of shapes and will put what ever fittings you want wherever you want. They are useable as potable water or black water, the only difference is the fittings. They sell direct to the customer or through third parties, direct is cheaper.
Metal of any kind is a bad choice for a waste tank.
