When building a new facility- be it a shed, barn, or warehouse, it is crucial to determine the simplest water storage system solution. This article discusses how you can calculate the size of tank you need and how much water to collect. Here are a few aspects to help you work out what size rainwater tank you need:
Although every scenario is exceptional, one general rule is to have at least four weeks of water supply. For instance, if you use 1,000L every week, consider getting a 4,000L tank. Alternatively, you can calculate the number of days you do not expect rain. Then, multiply that number by your daily usage of water.
Roof Harvesting Capacity
You should calculate exactly how much water would flow into a tank. That means assessing the size of the catchment surface (or your roof). Bear in mind that each square metre of roof area collects one litre for every one milimetre of rainfall received. Hence, you can determine your tank size by multiplying the roof area by the typical rainfall in your region. For example, if you have a one hundred square-metre roof in an area receiving 10mm of rainfall, you will need a tank size of 1,000L.
One Large Tank versus Smaller Tanks
You ought to consider whether to use one giant tank or several small tanks to collect and store rainwater. For instance, if your facility has an inclined roof, you can install one huge tank at one end to collect all the water or put two smaller-sized tanks at every end of the facility.
Using one large tank will save space, but it might affect your water supply in case something goes wrong. Typically, having two smaller tanks means you’ll collect an equal amount of water and still have adequate supply if one of them happens to fail.
The Bottom Line
It is crucial to use the above factors to work out the size of the rainwater tank you need before purchasing one. Also, since each property and facility is unique, you should speak to your water tank professional to determine what suits your needs best.
Rainwater or tap water, which is suitable for my garden? This is a question that you are probably asking yourself right now. If you want your garden plant to thrive, then it is better to collect rainwater, store it in a water tank then use it to water your plant as opposed to using town water. In this article, we are going to explain why rainwater is better than town water for your garden.
Rainwater is Pure
One good thing about rainwater is that it is more pure than tap water. It does not contain treatment chemicals such as chlorine and minerals that are often found in municipal tap water. Rainwater also contains less salt, which is more suitable for plants. The contaminants that tap water contains are generally not ideal for plants.
Rainwater Has Low pH
Another thing about rainwater is that it has a low PH of between 5 and 7, which is perfect for nutrient absorption. On the other hand, tap water has PH that is greater than 7, which can cause a problem known as nutrient lockout. Just like humans, plants also need nutrients and minerals to survive and thrive. If they don’t get this vital nutrient, then they will grow weak and eventually die. According to experts, the ideal PH of water to be used in the garden is between 5 and 7. Anything more than that will limit nutrient uptake.
It Saves Money
Another benefit of using rainwater to water your garden as opposed to rainwater is because it will help you save your hard-earned cash. It will not cost you even a penny to harvest rainwater. On the other hand, it will cost you a lot of money to water your garden with town water. It seems that town water is getting more and more expensive, so harvesting and using your own water over a ten year period will probably pay big financial dividends.
The worse thing is that even after spending a lot of cash, town water is not the best water for your plants.
