The Water Works™ Fresh Water Delivery with extra tank

The Water Works™ just became twice as good! The extra Water Works™ tank allows the system to provide 186 gallons of fresh water using a built in, on-demand pump. Designed to operate on regular household current, the circuits are protected by GFCI and a low-water electrical shut-off. It’s the perfect accessory to deliver water wherever people work for portable showers, sinks and fresh-water flush portable toilets.

The addition of a 250 or 300-gallon holding tank provides complete sanitation service.



  • Can be plumbed to fill from outside the trailer
  • When it is time to empty and remove, water quickly drains through its 1" valve
  • Cleaning the inside is easy through the 10" diameter access cover at the top
  • Tank is semi-transparent, so customers or service personnel can tell at a glance how much water is left
  • Add an additional 250 – 300 gallons of capacity with an additional tank

Advantages over other alternatives:

  • Easy to install, service, clean and transport
  • On-demand electrical pump delivers 186 gallons of fresh water whenever it is needed
  • Only 46 pounds empty, it can be transported to a service site by one person
  • Dimensions (60" high by 23" wide) are designed to fit inside even the smallest closet
  • Capacity to provide 450 – 500 gallons of water with an additional tank
