Over the past century, steel has become the undisputed champion of water tank construction, with over 100,000 tanks built – more than any other material. Remarkably, many of these steel tanks have been faithfully serving communities for over a century and are still going strong today.
While a well-maintained stainless steel tank can potentially reach a lifespan exceeding 100 years, regular maintenance is key to maximizing its longevity. Following established industry standards provides a reliable roadmap to keeping your water tank in top condition for years to come.
What are Industry Standards?
Regular inspections, professional tank cleaning, and routine maintenance are crucial for prolonging the lifespan of a water tank. Without these quality checks, no fabricated and installed system can continue to operate effectively.
In the United States, most potable water storage tanks adhere to specifications outlined by the American Water Works Association (AWWA). These standards are established and regularly updated by the AWWA Standards Committee on Steel Elevated Tanks, Standpipes, and Reservoirs, which includes members from consumer, general interest, and producer groups.
These industry standards provide guidelines on various activities, including the recommended frequency of inspections and the procedures for cleaning and maintenance. AWWA advises inspections every three to five years to enhance the longevity of a water tank.
Water Tank Lifespan and Safety
Want your water tank to last? Regular checkups and proper care are key! But that’s not all. Choosing the right material, considering the location, and how you’ll use the tank all play a role in keeping your water safe and the tank functioning for years to come.
Material
You’d prefer not to invest in a water storage tank that has a lifespan of only one to five years, so it’s advisable to steer clear of those made from plastic barrels. While they may be cost-effective, they only serve as a temporary solution for storing water.
In contrast, a polyethylene water storage tank presents a superior option. Crafted from UV-treated, food-grade, non-biodegradable plastic, it ensures robustness and durability. With proper upkeep, poly tanks can endure for ten years or more, and in some cases, up to thirty years.
For those looking for a durable, long-lasting investment, a stainless steel water tank is an excellent choice. Constructed from steel, it provides exceptional durability and an extended lifespan compared to other types of water storage tanks. A well-maintained stainless steel tank can last for more than three decades, often accompanied by a long-term warranty.
Location
The location where you install the water tank significantly influences its lifespan. If the tank is placed near a saltwater body, the corrosive effects of salty air can hasten its decay. Coastal residents may need to invest in additional protective measures, such as specialized sheeting, to shield their tanks. However, stainless steel tanks typically resist corrosion caused by salty air, making them suitable for coastal areas.
In regions with prolonged exposure to intense sunlight or dry conditions, the UV treatments on polyethylene water storage tanks may degrade more rapidly. Extended exposure to UV rays can accelerate the deterioration of the plastic material. Therefore, it’s crucial to shield polyethylene tanks from excessive heat to ensure their durability.
Usage
The function of the tank also plays a crucial role in determining its longevity. A tank utilized for storing clean, potable water intended for human consumption typically enjoys a longer lifespan compared to one used for harsh chemicals or saltwater.
In the case of stainless steel tanks designated for potable water storage, it is recommended to install a food-grade tank liner. This measure not only improves water tank safety but also prevents oxidized steel or zinc from leaching into the water supply. However, for polyethylene water storage tanks made from food-grade plastic materials, a tank liner is unnecessary as they are inherently suitable for storing potable water.
