High-Hazard Cross-Connection Control: Category 5 Break Tank Systems



Protect public drinking water networks from high-risk contamination.

Absolute Physical Separation via Certified Air Gaps

Dehoust water separation stations utilize an atmospheric break tank equipped with an unrestricted physical air gap (Type AA or AB). This configuration provides the highest possible level of backflow prevention. By separating the public potable water supply from non-potable process water through a physical gap, cross-contamination is physically impossible.

Engineered for Critical Infrastructure

Our Category 5 break tank systems deliver a safe, reliable, and uninterrupted supply of non-potable service water across a wide range of high-risk sectors:

  • Commercial Irrigation: Subsurface irrigation, agricultural watering networks, and turf management systems.
  • Industrial & Manufacturing: Process water lines, stagnant water storage, and facility wash-down bays.
  • Fire Protection: Dedicated fire suppression systems and emergency water storage tanks.
  • Critical Facilities: Healthcare facilities, laboratories, and specialized medical institutions.

Global Standard in Water Hygiene

Dehoust backflow prevention stations are engineered to meet strict international performance requirements for high-hazard cross-connection control. They simplify facility inspections, eliminate the risk of regulatory fines, and ensure absolute safety for public water networks
