Flat Bottom Utility Tanks

Flat Bottom Utility Tanks
Flat bottom utility tanks—also known as portable tanks, transport tanks, pressure wash tanks, detailing tanks, pest control tanks, or sprayer tanks—are versatile solutions for both residential and commercial use. These tanks excel in industries like manufacturing, auto detailing, agriculture, industrial applications, and liquid transportation, primarily for storing and hauling water, chemicals, and fertilizers.Available in black and white finishes:
  • White models are translucent, allowing easy visual monitoring of liquid levels.
  • Black and white models are FDA-approved for safe potable water storage and transport.
Manufactured by Norwesco using rotational molding from high-density virgin polyethylene resin, these tanks deliver seamless, rugged, and impact-resistant construction. Built-in UV inhibitors protect against sun degradation, enabling reliable indoor or outdoor use. They withstand a broad range of temperatures and weather conditions, ensuring a long service life.Sizes range up to 3000 gallons, with compact dimensions that fit easily into tight spaces, trailers, or trucks. Fully freestanding and self-supporting, they’re highly transportable—optional tie-down bands provide extra security during transit.Standard features include:
  • Gallon indicator markings for quick, accurate content level checks.
  • A vented threaded lid for secure access.
  • Outlet fittings on most models for convenient draining or connection.
Customization is available through One Source Plastics or Norwesco, including outlet fitting installation and tailored fabrication options for your specific needs.Every flat bottom utility tank is backed by a 3-year manufacturer warranty, giving you confidence in its durability and performance.These tanks offer an affordable, low-maintenance way to handle liquid transport and storage reliably.
