Fire water tanks
are water storage tanks with the purpose of having water readily available in case of a fire outbreak. They are usually found in buildings as part of a larger fire suppression system. These tanks are pretty large and installed on top or below the roof to provide water to sprinklers or hoses in case of a fire emergency.
Water tanks can also be created at a smaller scale with a similar purpose for RV or camper travel, aside from travelling with a fire extinguisher. RV or camper water tanks can also serve as a dual purpose water reservoir for general usage.
If the tanks are not properly looked after with regular maintenance checks, they could degrade and not function properly.
Water Tanks for Residential, Commercial and Agricultural Buildings
All buildings are required by law to have a water tank for the suppression of fire outbreaks, but once installed it is all too easy to forget about the maintenance until you have need of the system. If the water tank is faulty or leaking, you might run the risk of not being able to extinguish the fire entirely, or worse.
Water Tanks for RVs and Campers
When travelling, having your own water reservoir or water storage tank is very convenient, especially when those travels take you to more remote places. Most RVs and campers have fittings welded on to support a couple of 5 gallon jerry cans, but 5 gallons might not be much when travelling in parts of the country where water is less easy to source. Custom water tanks or storage baskets can be created for your trip that could hold more water canisters or tanks for your trip.
Custom Water Tanks for Fire Protection
Water tanks are available in a range of suitable materials including plastic, galvanised steel, stainless steel, steel liners, fibreglass, and concrete.
In generations past most water tanks were made from galvanised steel which are the water tanks usually found on older buildings and sheds. These days most new tanks have moved to a plastic or poly material which keeps the water quality better for longer, thus used in more potable water storage instances. Most of the other materials can slightly degrade over time, so if you’re looking for a potable or dual water system, one could still use steel, but with a lined interior made of poly. However the usage degrades over temperatures higher than 158 degrees.
Steel, steel liner and concrete tanks are the best options for choosing fireproof tanks.
Why Maintenance On Water Tanks Are Important
Water tanks need regular maintenance to remain safe and able to complete the critical tasks of delivering clean drinking water and water for fire suppression. A tank experiencing a breakdown in either of those areas could pose safety risks to people relying on the tank.
It’s nearly impossible to predict when a seemingly healthy water tank will suddenly go bad. Yearly maintenance checkups are therefore encouraged. This includes an external and internal inspection of the tank.
Here's a brief look at some inspection standards:
- Water levels: The water level should be checked quarterly for tanks with a supervised water level alarm. Monthly checks are needed for tanks without an alarm.
- The temperature of the water: The temperature needs to be maintained at a minimum of 40 degrees Fahrenheit to prevent it from freezing, for which a heating system is usually required.
- Heating system inspection: Heating systems are fuelled by steam, gas, coal, electricity, or solar power. Daily inspection is recommended for systems with no electric supervision system and quarterly inspection for those with a supervised system.
- Exterior inspection:
The supporting structure, foundation catwalks, ladders, and vents of the storage tank need to be inspected for any damage or weakening. They also need to be checked for degrading paint, ice build-up, leaks, and cracks.
- Interior inspection: Tanks without corrosion protection need to be inspected every 3-years, and every 5-years for tanks with coverage. They also need to be checked for pitting, rot, debris, aquatic growth, failure of interior coating, and blockage of the anti-vortex plate.
Interior inspection can be particularly challenging because the fire protection tank is mostly filled with massive quantities of water. When this occurs, steel frac tanks are used for temporary storage for water until the main fire protection tank is inspected and repaired, if required. In case of an emergency, water can be directly sourced from the frac tanks to handle a fire breakout.
