If you live in an area where water is scarce or costly, chances are you’ll look to rainwater harvesting for a supply of potable water. Some people should rely on water trucked in from other areas. In both these conditions it’s a must to create some form of water storage for potable water. Some individuals depend on plastic tanks, whereas others favor concrete storage tanks. If you employ concrete tanks, you need to be aware of a number of the disadvantages of this type of water storage.
Concrete is made with lime, a type of calcium carbonate. If the water in the tank is slightly acidic, it might probably leach calcium from the tank into the water. This makes the water harder and impacts the taste. Laborious water may also etch glass and plumbing fixtures. If you employ concrete to retailer water, the Texas Water Development Board recommends you coat the interior of the tank with a fabric permitted for use with potable water. This will even make the tank easier to scrub.
Concrete is less flexible than some other storage tank materials, akin to plastic or wooden, and may crack over time, particularly if the tank is buried. You’ll be able to patch concrete tanks, but you could need to drain the tank and let it dry so as to do so. And the next time the bottom shifts, you might have a new crack.
Whereas concrete just isn’t essentially the most expensive material for a water storage tank, a concrete tank can price more than a prefabricated plastic or metallic one. The Texas Water Improvement Board notes that poured-in-place concrete storage tanks are amongst essentially the most desirable, but these tanks will cost greater than prefabricated ones.
Instead of concrete tanks, you can buy a tank manufactured from fiberglass, plastic or steel. Fiberglass and plastic are lightweight, but can break down over time as a consequence of weather and solar. Metallic tanks can corrode over time and will impart a metallic taste to water. Tanks product of cedar or redwood look engaging and resist rot, but can dry out and leak in some climates, or develop moss in others. Stainless steel makes a durable tank that does not add a taste to the water but will be prohibitively costly.
