Water is becoming more expensive and, in due time, more scarce. Because of this, some homes and businesses are rethinking their water output doing everything they can to conserve this precious resource. On the other hand, not many people realize that thinking about their water input is also something they can be doing to save money as well as the environment. Rain catchment devices are becoming more commonplace in residential as well as small business models. By installing one on either a small or large application can reap a fair amount of energy savings.

How it Works

Rain catchment is moderately easy. All it takes is some gutters and/or downspouts with a large enough holding vessel to catch it all. A holding vessel could be a recyclable rain barrel, rain catchment tank, or collapsible rain barrel depending on how you will use your catch. These can be made of steel, plastic or wood and are usually placed alongside a home or building near the other outside devices such as an air conditioner fan. The formula for figuring out how much rainwater you can collect is:

1 inch of water x 1 square foot = 0.0623 gallons


1 inch of rain from 1,000 square feet provides 623 gallons

Either way it is a lot of water.

Rainwater Uses

Rainwater is applied in as many conventional uses as possible. Here are a few:

  •  Boil for drinking
  • Connect a hose to your tank and water your landscape.
  • Wash your vehicles
  • Industrial usage instead of paying for municipal water.
  • Indoor plant and cleaning needs
  • Refill fish ponds, bird baths, fountains, etc.
  • Clean sidewalks, driveways, windows and power wash decking without the guilt of wasting water.
  • Refill your house pool.
  • Give away to friends.
  • Use to flush plumbing.
  • Wash clothes.
The Benefits of Rain Catchment

There are a variety of benefits of installing a rain catchment system. It is not only one less utility bill, putting more money in your pocket, it also sends a message. It tells those around you that you care about recycling more than a few bottles. Most rain catchment systems are fairly easy to install and, if you want to get real creative, can be retrofitted into your original infrastructure. There is no need to adhere to community restrictions during a drought and in the beginning it is not necessary to hire a professional installer. Rain water filter and diverter kits can be purchased and setup on your own.

Why let all that free water soak into the grass and sewer system, why not grab a little gold from the sky and use it to your advantage? There are even organizations to help you along like the American Rainwater Catchment Systems Association (ARCSA) as well as your own water supply company that may have some suggestions. Either way, rain catchment seems like a win win choice.
