Xerxes Fiberglass Tanks:

Xerxes Fiberglass Tank


The Xerxes Advantage:

As communities, businesses and industries become increasingly accountable to meet LEED and other environmental requirements that require safe, design-proven storage, Xerxes is in the forefront with innovative answers. When considering the options in customized systems for water storage, facility designers and owners look for a long-term, structurally strong, watertight and cost effective solutions. That is exactly what the Xerxes fiberglass tank is.

For decades, Xerxes has been well-known as a major tank supplier to the petroleum industry, with more than 100,000 tanks installed. Many of the world’s largest oil companies rely on Xerxes to supply environmentally safe underground tanks for storage of gasoline at their retail service stations. Throughout the neighborhoods and communities of America, Xerxes underground tanks are in place, simultaneously storing products and protecting the environment.

Today Xerxes is taking its place in those same neighborhoods and communities as a major supplier of storage tanks for water — potable water, fire-protection water, irrigation water, gray water, rainwater, stormwater and emergency-supply water. Each time a Xerxes fiberglass underground water tank is delivered to a customer, the same performance standard has been met — a vessel for safe underground storage of water and careful protection of the environment.

Above Ground Plastic Tanks:

Above Ground Plastic Tanks

 

The above ground storage tank is available in an assortment of colors to blend with the environment, provide additional protection from UV rays and reduce algae growth.

Typical Above Ground Plastic Tank Features:

  • ANSI/NSF 61 Compliant
  • Manufactured with food-grade FDA approved virgin polyester resin in NSF certified plants
  • Storage tanks are seamless with one piece construction
  • Strong, durable construction
  • Hard-plumbing of plastic tank is not recommended due to the expansive/contractive characteristics of polyethylene; use elbows to allow flex
  • A concrete pad is recommended for installation, however, tanks may be placed on any flat level "compacted" surface
  • Designed for containment of water (8 lbs/gallon)
  • FDA approved High Density Linear Polyethylene (ANSI/NSF Standard 61)
  • Containers are impact and corrosion resistant
  • Tanks come standard with a filler fitting and a drain with plug
  • Inlet installed high near manway
  • Drain installed at bottom under manway
  • Ship from various locations in the USA

 


Fire Protection Associations:


The main associations for codes and standards are the National Fire Protection Association (NFPA) and the National Fire Sprinkler Association (NFSA).

NFPA: (www.nfpa.org):

NFPA develops, publishes, and disseminates more than 300 consensus codes and standards intended to minimize the possibility and effects of fire and other risks. NFPA membership totals more than 70,000 individuals around the world. NFPA makes its codes and standards available online to the public for free. Most codes and standards for fire protection systems are developed and published by the NFPA.

NFSA (www.nfsa.org)

NFSA is focused on fire sprinkler systems. Their mission statement is "To protect lives and property from fire through widespread acceptance of the fire sprinkler concept".

About NFPA 22:

NFPA 22 is titled the "Standard for Water Tanks for Private Fire Protection"

While strict interpretation of NFPA 22 Section 4.4.1 does not authorize the use of polyethylene (plastic) water tanks or corrugated steel tanks with removable plastic liners, many jurisdictions readily permit the use of plastic tanks because the alternatives are cost prohibitive. One important note regarding corrugated steel tanks with plastic (PVC or EPDM) liners is the concern that the liner could be sucked into the intake and block the flow of water. Precautions such as the use of a Tee connector or similar means to provide an alternate intake should be implemented.

According to the NFPA Technical Advisor board, this standard is specifically written to cover technical details which apply to fire suppression systems which employ fire suppression sprinklers. Water tanks used for drafting (water drawn into a fire truck) do not fall under the scope of NPFA 22. Under some circumstances, NFPA 1142 Annex-B can be referenced for underground cistern applications.

About NFPA 13:

NFPA 13 is titled the "Standard for the Installation of Sprinkler Systems"

NFPA 13D is titled the "Standard for the Installation of Sprinkler Systems in One- and Two-Family Dwellings and Manufactured Homes". According to NFPA, there are no specific criteria for water tanks (materials or structural).

NFPA 13-R is titled the "Standard for the Installation of Sprinkler Systems in Low-Rise Residential Occupancies" and it applies to residential homes up to 4 stories.

NFPA Standards for Above Ground Water Tanks Used for Drafting Purposes:

According to the NFPA Technical Advisory board, there is no standard which applies to the materials or construction of above ground water tanks which are used for drafting purposes (Case# 31873) 5/13/14.

Drafting Connection (FDC) Standards:

The connection to a water tank for residential fire protection is specifically called a drafting connection and is also referred to as a Fire Department Connection or FDC. This is the most important part of the system to get right because the fire department needs to be able to connect to your water source in order to use it. The connection typically consists of a 4” pipe system from the tank with a shutoff (Gate) valve and a suitable connection for the local fire department. You should contact your local fire department to get the specifications for their drafting connection. One typical connection is called National Hose Thread and is abbreviated by NH or NST. Various sizes are available but 4-1/2" NH/NST and 2-1/2" NH/NST are very common. This is a threaded male connector. A matching plastic or brass cap with chain is typically required as well.

Dual-Service Tanks:

A dual-service tank is a tank which is used for both fire protection and is also used for other purposes. The main goal of a dual-use system is to make sure the tank always has an adequate supply to fight a fire, regardless of usage for other purposes. The way this is typically achieved is by using separate plumbing systems for fire protection and for residential use and insuring that the plumbing pipe for residential use does not extend below the water elevation which is necessary for fire protection. The NFPA 22 standard also specifies that separate plumbing systems be used and specifies the same requirement for keeping the plumbing for other purposes above the elevation for fire protection.

Fire Sprinkler Water Quality:

NFPA 13 applies to rainwater collected for fire sprinkler systems. NFPA 13 requires that in the Owner's Certificate (Section 4.3(3)), the owner of the building shall be aware of any special conditions in the water supply that may be responsible for corrosive conditions. This would require an evaluation of the water by Section 24.1.5 of NFPA 13. Water that may have fertilizers or other chemicals could contain an additive (Section 4.4) that can be very corrosive or detrimental to the system.

Below is a list of sections from NFPA 13 that may apply to rainwater if used for sprinkler systems:

• 4.3(3) Owner Certificate

• 4.4 Additives

• 24.1.5 Water Supply Treatment

• 24.1.5.2 Water Supply Evaluation

• 24.1.5.3 Biocides

• 24.2.1 Water Supplies

While a thorough reading of these sections is recommended, it can be summarized as: the water source and quality has to be evaluated prior to implementation and must be consistent. If necessary, NFPA and/or NFSA should be consulted for technical assistance.
