    Non-Potable Water Tank Rentals

    Serving Northern California and Northern Nevada.

Product Features

Our 3 stall portable restrooms are designed to deliver a clean and professional restroom experience:

Typical non-potable fresh water tank sizes vary significantly depending on whether they are integrated into a single unit or part of a larger restroom trailer system. 

Portable Toilet Integrated Tanks

Standard porta potties often have a small internal reservoir if they feature a flushing mechanism or a built-in sink. 

  • Standard Flushing Units: Typically hold 1 to 3 gallons of fresh water for flushing and bowl cleaning.

  • Hand Wash Stations: Standalone portable sinks generally have a fresh water capacity of 20 to 25 gallons, supporting approximately 300 to 350 washes per fill. Some larger high-capacity stations can hold up to 45 gallons.

  • ADA Units: Oversized or handicap-accessible units often feature larger reservoirs, reaching 80 to 100 gallons to extend the time between services.

Why Non-Potable Water Tanks?

Not every project requires a drinking water supply, but every site needs a reliable utility water source. Our non-potable fresh water tanks provide a high-capacity solution for restroom trailers, hand-wash stations, and construction site needs where drinking-grade water isn't required.

Benefits include:

  • Reliable Utility Water Supply: Ideal for flushing toilets, dust suppression, and equipment cleaning.

  • Restroom Trailer Support: Seamlessly integrates with mobile sanitation units to provide a steady flow for sinks and stalls.

  • Mobility: Compact, durable designs allow for easy delivery and placement across any terrain or job site.

  • Built for Tough Conditions: Heavy-duty, UV-stabilized polyethylene construction designed to withstand the rigors of construction.

  • Cost-Effective Infrastructure: Avoid the high costs of temporary plumbing or permanent tank installations for short-term sites.
