Proper Maintenance of Water Storage Tanks
Underground water tanks have a long lifespan. Most typical water storage tanks have a life expectancy of 20 years, though some water tanks are over 100 years old. The distinction between the two is in the proper maintenance procedures.
Maintaining custom water tanks requires ensuring that the correct water tank liners are installed or that the water tank liners are replaced as needed. Aside from water tank liners, there are several other important aspects of water tank inspections and maintenance.
Regular Weekly Foundation Checks: This is perhaps the most important aspect of water tank maintenance. Water tanks are designed to last. They are also designed to be used in potentially harsh environments with large temperature swings, strong winds, and a lot of wear and tear from other elements. As a result, small cracks, deterioration, or corrosion must be detected early. These minor issues, if detected early, can be resolved quickly, preventing long-term, costly damage to the water tank. In addition to weekly checks, it is a good idea to have the tank inspected and cleaned out every three to five years. This is an excellent time to replace your water tank liners (for great liner products, check out our selection, everything from industrial tank liners to water treatment tank lining). Additionally, yearly cleanouts are recommended for areas with high sediment. Make sure you understand how the unique weather and location of your tank will affect your maintenance requirements.
Take Care of the Coating: A high-quality coating is critical for lowering maintenance costs over time. Your tank’s primary defence against corrosion is the coating. High-quality coatings and water tank liners will help eliminate metal loss, saving you money on costly welding repairs. Maintaining a good coating allows you to simply “topcoat” each year instead of starting from scratch when it comes time for maintenance. If you’re going to outsource your water tank coating work, make sure you get very detailed and specific documents about the type of coating work you want. Anyone hired to work on the coating should be familiar with the atmospheric conditions unique to your area. These include humidity, due point, air, and steel temperatures, all of which have an impact on the coat’s lifespan. If the weather turns bad, a good contractor will call it quits.
While You’re At It, Keep Up with Technology: Every year, new advances in water tank technology are made. While it may not be as flashy as a new smartphone or gadget announced at a major tech conference, advancements in storage tank maintenance are being made. 100% solids coatings, for example, and improved active and passive mixing systems are both new trending technologies. Knowing about new technology can help you get the most out of your water tank liners and other equipment as you maintain your tanks.
Eliminate Algae (when possible): While this isn’t always possible when it is, do it. Use a completely opaque water storage tank to eliminate algae. Algae requires light to grow because it uses photosynthesis. The use of an opaque tank eliminates light, creating an environment in which algae cannot grow. In addition, add 1/4 teaspoon of bleach to each gallon of stored water. Of course, this should only be done with tanks where it is legal. Bleach can kill existing algae and prevent the growth of new algae. Use 5.25% hypochlorite bleach, and NEVER combine bleach and chlorine in the same solution. Use either one or the other. If you’re going to use chlorine, use 4 parts chlorine to 1 million parts water. Water is safe to drink or use for irrigation even at this low ratio. However, if you are concerned, you should first consult with your local regulators.
These suggestions will assist you in maintaining a proper water storage tank. Remember that proper prior maintenance makes a significant difference in the long run. Avoid costly repairs by maintaining your water tank inspections and maintenance.
