This is the PolyJohn 300 Gallon Portable Holding Tank (Natural). Similar to our 250-gallon model, the PolyJohn 300-gallon holding tank is a necessity as a sanitary receptacle for waste for an outdoor rest area where indoor plumbing is not an option. Our functional and discrete holding tanks reassure workers or guests that waste is being stored safely.
PolyJohn holding tanks are made of an extremely durable plastic, and easily work with different plumbing configurations to ensure that your rest area remains as clean and uncluttered as possible. Specialized design means that our holding tanks can be used with many of our portable restroom or sink models interchangeably.
The 300-gallon capacity allows for maximum waste storage.
These unique portable holding tanks eliminate the use of threaded and solvent-cemented conventional plumbing fittings, which are usually discarded after each use. The 3" (7.6cm) ports utilize "Fernco" flexible rubber couplings, which are available in a variety of pipe sizes and plumbing configurations such as couplers, elbows, tees and caps. These flexible fittings are re-usable. Two sizes of tanks are available. These durable plastic polyethylene tanks are supplied with the top, center port #4, cut open with a 3" rubber cap and clamp provided. Other ports can be cut open and a rubber cap and clamp supplied at the customer's request for a nominal fee.
