Fire Water Loop and Hydrant Systems
Industrial fire protection water supply systems and hydrant installation for DFW facilities.
Fire protection water supply systems are essential infrastructure for industrial facilities in the DFW Metroplex. Property developers and building owners depend on properly designed and constructed fire loops and hydrant systems to protect their investments and meet code requirements. Our crews install complete fire water infrastructure from municipal connections through building entries and site hydrant networks.
Fire loop systems encircle buildings or building groups, providing multiple flow paths to ensure water availability even if a section of pipe is damaged or out of service. Loop sizing depends on fire flow requirements established by fire protection engineers based on building size, occupancy, and sprinkler system demands. We install loops in ductile iron or polyethylene pipe depending on project requirements and soil conditions.
Fire hydrants are positioned according to code requirements and fire department preferences. Typical spacing ranges from 300 to 500 feet depending on the jurisdiction and building type. Hydrant placement must consider fire department access and operational needs. We coordinate with local fire marshals to verify hydrant locations meet approval.
Post indicator valves (PIVs) and other fire protection control valves are critical system components. We install PIVs at strategic locations to allow section isolation for maintenance or emergency response. All valves are clearly marked and accessible for fire department personnel.
System testing verifies that installed fire water systems can deliver required flow rates at appropriate pressures. We coordinate flow testing with fire departments and fire protection contractors, documenting results for project records and insurance purposes. Systems must pass hydrostatic pressure testing before acceptance.

Frequently Asked Questions
How are fire flow requirements determined for industrial buildings?
Fire flow requirements are calculated by fire protection engineers based on building size, construction type, and occupancy. Sprinkler system demand, hose stream allowances, and fire department operations are all considered. Municipal fire marshals review and approve calculated requirements.
What pipe materials are used for fire loops in North Texas?
Ductile iron pipe is most common for fire water systems in the DFW area due to its durability and resistance to damage. Polyethylene pipe is sometimes used where corrosive soil conditions exist or where future settlement is a concern. Material selection is coordinated with the project engineer.
How far apart must fire hydrants be placed?
Hydrant spacing varies by jurisdiction and building type. Generally, hydrants are spaced 300-500 feet apart, with specific requirements for hydrant locations near building entrances, fire department connections, and at intervals along fire lanes.
What testing is required for fire water systems?
Fire water systems require hydrostatic pressure testing at 200 PSI for two hours. Flow tests verify system capacity meets design requirements. Bacteriological testing may also be required. All testing is documented and submitted for municipal acceptance.
Can you install fire water systems while buildings are under construction?
Yes, fire water infrastructure is typically installed during site development, before or concurrent with building construction. Early installation ensures fire protection is available during construction and ready for sprinkler system tie-in.
