PolyJohn 250 Gallon Holding Tank

PolyJohn’s 250-Gallon Holding Tank is a vital solution for long-term portable restroom rentals, such as outdoor rest areas or multi-day events. Designed for functionality, safety, and discretion, this tank provides peace of mind for both workers and guests.

Constructed from highly durable plastic with thick-wall, heavy-duty design, the tank includes multiple ports to accommodate various plumbing setups. It can be easily installed using rubber couplers and clamps. The tank is also available in a natural color that allows fluid levels to be seen from a distance—a requirement in certain states.

When indoor plumbing is unavailable and bulk waste storage is needed, a holding tank is essential. The 250-Gallon Holding Tank is perfect for job site trailers, RVs, emergency relief camps, or any situation requiring reliable, clean, and high-capacity outdoor waste storage.
