In the past century, more than 100,000 water storage tanks have been built, a number that surpasses those made from any other construction material. Many steel water tanks have been in service for over a century and continue to function today.
Certainly, under favorable conditions, the lifespan of a stainless steel water storage tank can exceed a century. While not every tank may last that long, regular maintenance increases the likelihood.
To maintain your water tank’s optimal condition and ensure its longevity, following industry standards is a reliable approach.
What are Industry Standards?
Regular inspections, professional tank cleaning, and routine maintenance are essential for extending the lifespan of a water tank. Without quality checks, no fabricated and installed system can continue to operate effectively.
In the United States, most potable water storage tanks are constructed according to specifications outlined by the American Water Works Association (AWWA). These standards are established and updated by the AWWA Standards Committee on Steel Elevated Tanks, Standpipes, and Reservoirs, which comprises members from consumer, general interest, and producer groups.
These industry standards provide guidance on various activities, including the frequency of inspections and the procedures for cleaning and maintenance. AWWA recommends inspections every three to five years as a means to prolong the lifespan of a water tank.
Water Tank Lifespan and Safety
Extending the lifespan of a water tank beyond its expected expectancy requires constant maintenance and inspection. Additionally, ensuring water tank safety involves considering three essential factors: material, location, and usage.
Material
You wouldn’t want a water storage tank that lasts only one to five years, so it’s best to avoid those constructed from plastic barrels. While they may be inexpensive, they only serve as a short-term water storage solution.
On the other hand, a polyethylene water storage tank is an excellent option. It’s made from UV-treated, food-grade, non-biodegradable plastic, ensuring durability and longevity. With proper maintenance, poly tanks can last for a decade or more, and in some cases, up to thirty years.
For those seeking a long-term investment, a stainless steel water tank is an ideal choice. Constructed from steel, it offers superior durability and a longer lifespan compared to other types of water storage tanks. A well-maintained stainless steel tank can last for over three decades, often with the added benefit of a long-term warranty.
Location
The location where you install the water tank also plays a significant role in determining its life expectancy. If the tank is situated near a body of saltwater, the corrosive effects of the salty air can accelerate its deterioration. Coastal residents may need to invest in additional protective measures, such as specialized sheeting, to safeguard their tanks. However, stainless steel tanks are generally resistant to corrosion from salty air, making them a suitable option for coastal areas.
In regions with constant exposure to intense sunlight or dry conditions, the UV treatments applied to polyethylene water storage tanks may degrade more quickly. Prolonged exposure to UV rays can lead to premature deterioration of the plastic material. Therefore, it’s essential to protect polyethylene tanks from excessive heat to ensure their longevity.
Usage
The usage of the tank also significantly influences its service life. A tank used for storing clean and fresh water intended for human consumption will generally have a longer lifespan compared to one used for harsh chemicals or saltwater.
For stainless steel tanks used for potable water storage, it’s advisable to install a food-grade tank liner. This not only enhances water tank safety but also prevents oxidized steel or zinc from leaching into the water supply. However, for polyethylene water storage tanks constructed from food-grade plastic materials, a tank liner is unnecessary as they are inherently suitable for storing potable water.
