Water is scarce in different places, which prompts people to look for alternative sources. Depending on their financial capabilities, most opt for rainwater harvesting of varied scales. When considering getting a system for the same, consider the following factors beforehand to ensure the collection of rainwater is efficient and suitable.
The Tank Size
Without a doubt, the size of the rainwater collection tank determines how much water you will be collecting at a go. If your project is geared towards giving your residents an alternative water source and avoid overusing the municipal one, a large tank would be necessary. On the other hand, if you only need water for small household usage, a small to medium tank would be ideal.
The above is a logical considering. However, it would also be important to consider the initial setup costs. To be on the safe side, ensure to consult rainwater collection experts in your area.
Roof Size
The size of the roof to be used for water collection will determine the amount of water collected at a go. If you need plenty of water, but your roof is considerably small, then you may need to improvise and source for other water sources such as grey water. A large roof may be ideal for large-scale water harvesting but may also require that you install a larger storage system.
Location of the Storage System
Ideally, a tank would serve you better if it is placed at a higher level. However, the guttering will be below the tanks in most cases, which would hinder water harvesting. Weight is another consideration that you should look into if you are thinking of putting your storage tank at a higher surface.
Often, people who need more efficiency and have larger tanks prepare a setup surface for them on the ground. You may also do it depending on the specifications of your yard or, better yet, go for an underground tank with better water pumping systems.
Consider the Demand
Are you looking for a rainwater harvesting system for a rental apartment or your household usage only? Are you setting one up for your work or business place and which consumes plenty of water? By answering these questions, you can get a clearer picture of the volume of water you will need to harvest as well as the size of the storage system you will need.
