No portable restroom area is really complete without a holding tank. Holding tanks are sanitary receptacles for waste where indoor plumbing is not an option. Both functional and discrete, PolyJohn holding tanks are a necessity for any long-term portable restroom rental. Whether your customers are creating an outdoor rest area for a work site or for a special event, our tanks reassure their 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.
