One can’t just make a quick decision and get a water tank of any size and expect it to provide the needed water supply for their facility or household. This decision requires precise calculations and considerable thought. You need to consider the size of the free space you have for the water tank and calculate how much water you use to ensure that you will not have to take drastic maintenance measures. All of this can be too much to think about for those buying a water tank for the first time.
Here is a simple guide on how you can determine the right tank size for your house or building and how to choose one that suits your needs.
The Amount of Water you Need
To get the ideal water tank size, you need to calculate how much water you consume per day. Then, multiply that by the number of people living with you or using the same water line. On average, a person would use up to 115 liters of water per day, meaning if you live in a household with three other family members, your daily consumption of water combined would be around 500 liters. When comparing different tank sizes, aim for the ones that provide you with at least a month’s worth of water supply or more. Therefore, your minimum capacity options for the water tank in similar conditions should start from 20000 liters up to 30000 liters. If you live with more people or share your water supply with other residents in the same building, then get bigger tanks like a 50000-liter tank or a 100000-liter tank. Water consumption also differs depending on the habits and needs of the individuals using it; determine how you will be using the stored water and the amount of water you use for certain activities.
Your Budget
You might also be wondering whether you should make a big purchase and invest in a large water tank, or stick to your needs, and get a more suitable size. To decide, you will need to understand that water tanks can save you some money annually. The initial cost of buying a large tank might be a little expensive, but when considering your monthly water bills, you will notice that using a tank will save you a few hundred dollars. Considering the amount used for cleaning, cooking, gardening, or showering with tankless water heaters, large tanks are more sustainable and reliable when it comes to providing large amounts of water. This does not necessarily mean that you should buy one big water tank; you could invest in a couple of small water tanks to maintain a consistent water supply. Regular maintenance is required to protect stored water from contamination and prevent your tank from getting damaged or dirty, so you might want to consider getting a backup tank just in case you run into any problems. Having smaller water tanks will save space and ensure that you are capturing more rainwater than you would with a single large water tank.
The Size of Your Roof
Getting a water tank for your roof might require additional calculations to determine the right size. One liter of water can be captured from every 1 mm of rainwater collected in your tank – this is for every square meter of your roof space. To calculate the amount of water that your tank will store based on the size of your roof, multiply the number of square meters by the amount of rainwater received. This will help you determine the most suitable tank size or indicate how much water the tank will be providing. For example, on a 100 square meter roof, you can install a water tank of 1000 liters if the rainfall amount is 10 mm.
Every house or facility will have different needs. So, it is very important to run a few of these calculations or consult an expert to help you choose the right water tank size. It is also crucial to understand how you will maintain the tank to keep the water clean and ready for use. When water is stored in an inactive state, it is very easily contaminated. Knowing how to prevent this will help you save a lot of money and ensure that you and your family are using fresh, clean water. There are so many possibilities to utilize rainwater; it is free, healthy, eco-friendly, and available everywhere, regardless of where you live, so make sure you buy a tank that allows you to make use of it.
