How can I build a rainwater harvesting system?

Building a rainwater harvesting system involves several steps. First, you'll need to choose a collection area, like your roof. Then, install gutters and downspouts to direct the rainwater into a storage tank. Do you have a specific location in mind?

Yes, I want to set it up in my backyard. What size tank should I use?

The size of the tank depends on your roof area and your water needs. A common rule is to collect about 600 gallons of water for every 1,000 square feet of roof area. How large is your roof?

It's about 800 square feet. How do I ensure the water is clean?

To keep the water clean, you should install a first-flush diverter to discard the initial dirty water. Additionally, use a fine mesh filter at the inlet and ensure the tank is covered to prevent debris and insects.

What maintenance does the system require?

Regular maintenance includes cleaning the gutters, checking the filters, and inspecting the tank for any leaks or algae growth. It's best to do this at least twice a year.
