Decide On How You Want To Use The Water

One of the most important things you’ll first have to consider in choosing your water supply is deciding how you want to use the water. The reason behind this relates to the attaching systems you’ll have to include alongside your water tank.

If your intended purpose for the water tank is to supply water for outdoor use, then the whole water tank system may only be simple. You’ll probably just need the licensed supplier to take care of the installation rather than go all out with calling for a plumber. 

However, if the primary purpose for your water tank is indoors, the installation may be more complicated. This is because you may need a filter and hard water softeners, hot water curing systems, and filters, among the many, to accompany the water tank, so the water you store and collect remains safe for consumption. 

Making this decision early on allows you to ensure that you make the right choice right from the very beginning. This is also crucial, so you won’t forget any essential add-on parts you need to include with your water tank for it to stay the practical choice for your household’s needs.

Determine The Proper Tank Size

You don’t need to go all out with having the biggest water tank size, especially when you’re only a small household. You can be more cost-efficient when you stick only to the water tank size that you need. So, another handy tip that can help you out when choosing a water tank is determining the proper tank size you need. 

Here’s a sample computation to give you an idea of what to expect. On average, an individual will consume at least one gallon of water daily. Then, consider the number of days you want your water tank to be able to supply you with backup water. Multiply that with the number of people in your household. That’ll give you a number as to how many gallons your water tank size should have for it to hold your family’s needs and consumption.

Calculate How Much Water Can Be Harvested From Your Roof

Determining the amount of water you need to have stored as a backup is one. Apart from this, it’s necessary to know the amount of rainwater that can be harvested from your roof. This information is vital in coming up with the decision on the size of the water tank that is best for your home. 

You see, if your roof can harvest quite a significant volume of water, then you’ll want to maximize that as well. You can ask for a proper calculation from the water tank supplier, based on the area of roof you have.

Assess Which Material Of The Water Tank You Prefer

Another fact you should be aware of about water tanks is that they’re made of various materials. Each has its respective pros and cons. So, the deciding factor is your personal preference.  

Along that line, some of the most common types of materials used for water tanks include:

  • Metal tanks are made from corrugated or flat roll material, usually coated or galvanized. 
  • Concrete tanks are commonly used for industrial and agricultural purposes and are rust-resistant. 
  • Polyethylene (plastic) tanks are generally the more popular option because it’s often cheaper while still durable. 
  • Fiberglass tanks are made to withstand extreme temperatures and are rust and chemical-resistant.


Water tanks don’t necessarily come in cheap. They come at quite a price. So, when you’re buying one for your home, you must be making the right choice. It should be one you’ve given so much thought and research into. When you have the right water tank needed by your home, your water supply will surely stabilize. Thus, you won’t ever have to worry again about possibly going through little to no water supply when water problems in your area will arise.
