Site-specific live loading

Water storage tanks must comply with local building codes, laws and ordinances, and modifications may have to be made for each specific location where a tank is built/installed. To ensure compliance requirements are properly addressed and building code inspections are passed, we offer the option to employ a service called “structural design calculation package.” This includes documentation that is accredited (stamped) by a Florida-licensed engineer.

Miami Water Heater ensures the products are built to our customers’ precise standards. Water tanks are often more than an aesthetic feature or simple convenience – they play an important, functional role and must be unquestionably reliable. For example:


Fire Protection

CorGal® Tanks can be engineered and designed to be fire protection water tanks that comply with local, state and national fire protection codes and standards such as:
  • NFPA-22 (Water Tanks for Private Fire Protection)
  • NFPA-1142 (Water Supplies for Suburban and Rural Fire Fighting)
Alternative water sources may be required by local fire departments when the on-site water available does not meet flow requirements. Firefighting equipment can be attached to fire prevention tanks or they can also be fitted with fire-truck-hose compatible connections to complement fire trucks. Water tanks must be fail-safe when 1,000+ gallons per minute are being used. You can rest assured that CorGal® tanks will be up to the test as they are engineer-tested to ensure they perform flawlessly during a crisis. Fire protection tanks feature the following upgrades:
  • Higher gauge sidewall
  • Long-lasting anti-vortex fittings (not painted metal)
  • Roof vents
  • Premium water level indicators
  • OSHA compliant ladders

Tank Towers

If gravity is needed to make water flow efficiently, tanks can be built on a tower or a high-elevation spot. Some of our clients don’t necessarily need gravity for their water supply to flow but merely like the look of the tanks, which a tower or elevated terrain can exploit. There are even businesses that don’t use our tanks for water storage at all but rather for highly visible signage that makes their locations stand out.
