Pioneer Water Tanks for Suburban and Rural Firefighting

NFPA 1142 specifies water supplies for firefighting purposes in rural and suburban areas. This is typically defined as within areas that have less than 500 – 1000 people per square mile. If the water structure is unable to supply a minimum of 250gpm at 20psi above the average domestic use, supplemented water supplies may be required. The NFPA 1142 standard may also be implemented whenever the AHJ, the authority having jurisdiction, requires it.

Areas without existing adequate and reliable water supply systems, as determined by the AHJ, can supplement or add a water storage tank to fulfill requirements. The local authority determines the capacity needs, based on the fire flow equation stated in the local fire code.

“Cisterns should have a minimum usable volume as determined by the AHJ, based on the methods described in Chapter 4. There is no real limit to the maximum capacity.” NFPA 1142 Annex B.4.1

Pioneer Water Tanks have engineering packages available for standard capacities. Our qualified engineering personnel and independent consultant engineers can also provide a stamped cover letter per project, as well as provide documentation as required.

“The design of the cistern must be submitted to the AHJ for approval prior to construction. All plans must be signed by a licensed/registered professional engineer.” NFPA 1142 Annex B.4.3.5

NFPA 1142 Fire-Flow Requirements for Buildings, Determining the Water Tank Capacity Requirements

The fire flow calculation covered in NFPA 1142 is intended for areas without available water systems, where a supplemented or additional water supply is required. The NFPA 1142 method employs the volumetric capacity of the specific structure to calculate the minimum water supply.

The NFPA 1142 fire flow formula is:

Minimum water supply (MWS) = (Total structure volume) ÷ (Occupancy hazard classification number) * Construction classification number

The AHJ has the final say to capacity and connection requirements. Pioneer Water Tanks work well with local specifications and have permit packages ready.

DISCOVER THE DIFFERENCE IN PIONEER WATER TANKS

HEAVY-DUTY TRUSSES

Our exclusively engineered trusses are hot-dipped galvanized steel equipped with a swivel foot. As a result, it provides optimal movement in your tank in extreme conditions. As your tank adapts to external conditions, you can rest easy your tank won’t fail when you need it most.

HIGH TENSILE BOLTS

Specifically engineered for strength and durability, our bolts are galvanized high tensile 8.8 grade. Not only are they hardened and super strong, but they are also the most resistant bolt on the market to shear under pressure.

PIONEER V-LOCK®

Our exclusive PIONEER V-LOCK® is specifically engineered to maximize the strength of corrugated steel without damaging or stretching your liner when molded to the tank wall. Independent testing proves that the PIONEER V-LOCK® provides the ultimate shock absorption to prevent movement or sinking.

FIRE HOSE FITTINGS

Be ready for fire emergencies with our fast, convenient firefighting valve options. Outfit your tank with anti-vortex fittings and firefighting adapters for quick access during a fire emergency.
