    The NFPA 22 standards for water storage for fire protection sets the minimum requirements for the design, construction, installation, and maintenance of water tanks and their accessories.


    Chapter four of the NFPA 22 Standards for Private Fire Protection covers the general requirements while the other chapters go into depth by the type of water tank.

    1. Capacity and Elevation (4.1):

    The size and elevation of the water tank are determined by the individual property conditions, after due consideration of all of the factors involved. Typically the local fire marshall will determine the fire flow requirements that decide the capacity of tank needed for the property to be permitted.

    2. Water Sources (4.2):

    The water source for filling the tank needs to be adequate and dependable, with allowance for its reliability in the future. If the water supply from a public service main isn’t adequate in quality, quantity or pressure (measured in fire flow for fire protection)- an alternative water source needs to be provided (like an extra water storage tank on the property).

    Our sacrificial magnesium anodes significantly extend the life of your water tank by protecting the tank from corrosion. Made from magnesium, the anodes erode in place of the water tank, thereby protecting the steel and allowing the tank to last longer than other systems. Pioneer Water Tanks recommend your anodes be replaced every 10 years so you can enjoy the benefits of your tank for life.


    Reduce the number of contaminants to protect your precious water supply with Pioneer Water Tanks’ high-density foam sealer.


    Pioneer Water Tanks provides a 6” diameter overflow downpipe, the largest overflow system on the market. The overflow size moves excess water away from the tank quickly to effectively reduce pressure on your tank and avoid costly damage to your tank components.

    All Pioneer Water Tanks can be orientated to suit client requirements. We have the flexibility to insert Nozzles (inlets and outlets, etc) through the tank wall, roof or floor. They can adapt to most flange tables – BSP, D, E, DN, DIN or ANSI. We include our standard polyethylene fitting with an option to upgrade to galvanized steel or brass fittings. Our commercial line of nozzles range from 2” – 16” diameter with even more options outside of this range.


    Nozzle Orientation


    Nozzle orientation is an important component in tank design. The position and size of the nozzles will determine the “effective” or usable storage capacity. Before we manufacture any commercially designed water tank we create a nozzle orientation drawing. This allows you (or the engineer) to nominate the position of each nozzle – inlet, outlet, overflow etc. to match up with existing or new pipework.

    Pioneer Water Tanks are engineered to NFPA standards for water storage for fire protection. The tank’s firefighting adapters and nozzles options are compatible with fire hoses in America. Our tanks come standard with poly outlet and inlets but they can all be upgraded to our brass options. Additional accessories are available for different compliance needs. We stock a range of firefighting fittings that provide instant access to fire reserve storage in case of an emergency that comply with NFPA 22 standards. Turn your water tank into a water source for firefighters with hose fittings.

    Pioneer Water Tanks offers our industry leading 20 –year conditional warranty on the tank and liner. Commercial projects are warrantied per project, based on the application and applicable requirements.
