It's the process of intercepting or collecting storm water. Rainwater harvesting systems are typically used to collect and store the water that's collected to be used on landscaping.

Rainwater can be harvested from roofs, driveways, walk areas, patios, and other non-porous areas.

It's important to note that the average roof sheds 160 gallons of rainwater per hour during periods of moderate rainfall. Using a rainwater harvesting system can help you collect at least some of that rain and will save a lot of domestic water and money.

How to Collect Rainwater

The best method handling a rainwater harvesting system is to design a home or building with the intent of collecting rainwater in mind. This is simplest because during construction catchment areas can be designed and conveyance systems are easily to put into place.

If you own an existing home, don't let that get you down! Rainwater can also be harvested from existing homes and structures, although not as thoroughly or efficiently. We can still make use of this valuable resource to reduce our domestic water needs. Follow these guidelines and tips for harvesting your own rainwater.

Rainwater Harvesting System - Barrels:

The most simple system may already be in place on your existing home - a gutter and downspout system. With gutters and downspouts, you can simply direct the water runoff from the downspout to a storage container.

These containers are readily available, are low cost, and are a very effective means of converting your wasted storm water into a usable irrigation source. Using a storage container instead of allowing rain to flow into your yard allows you to control where and how much water is used in your landscaped areas.

Also, by storing water in a container with a lid, it minimizes breeding grounds for mosquito's and other harmful pests. Using a lid will also prevent children and pets from accessing the water.

Rainwater Harvesting System - Rain Spout Diverter Unit:

When you use a rain spout diverter unit, rainwater flows from the roof into the gutter downspout and gets captured in the water saver reservoir. When the reservoir fills with water, it takes the path of least resistance and exits via a spout at the bottom of the unit, through a hose, and into your water barrel.

When this barrel is full, back pressure occurs and the water then exits out of the upper exit spout into the normal drainage system. For full back pressuring to occur, there can be no openings on the top of the rain barrel. The 7 foot hose that comes with the kit allows the rain barrel to be moved away from your home or building placed in a low visibility area.

Rainwater Harvesting System - Catchment:

Rainwater catchment is a term that refers to larger collection systems for rainwater harvesting. Typically these systems are located either above or below grade and can be built from plastic liners, fiberglass or ceramic cisterns, or poly tanks that are prefabricated.

You'll often see these systems in rural areas that receive a good deal of rain each year. Because of the large appearance and cost to install, they aren't often uses in subdivisions or in areas with a small amount of rainfall. They can, however, be installed underground, to avoid the appearance issues - they aren't the prettiest things you've ever seen!

Just Using Buckets or Decorative Pots

If you aren't interested in installing an entire rainwater harvesting system, you can still collect some rainwater to use in your landscaped areas. Many gardeners are starting to use decorative buckets and/or pots in their flower beds. Those containers capture water when it rains and can then be used to water. This method won't get you nearly all the water you need, but anything you can save and use later is a good thing.

What About Rainwater Contaminates?

If you live in an urban or industrialized area and wish to collect rainwater, you should be aware that there are contaminates that have to be dealt with. The best method of handling this is to obtain a storage device that incorporates first flush technology.

Typically, the rainwater from the first few minutes of a storm will have the greatest amounts of contaminates and will contain bird droppings, dust, and other local contaminates. A first flush device will incorporate a rising ball that floats and will close off an opening after an inflow of approximately 5 gallons. Water is then diverted to a pipe leading to a storage container. Dirty containers may become a health hazard or a breeding ground for mosquito's and other pests.

Roof washing is not essential when the rainwater is harvesting strictly for irrigation purposes. However, it's also important to note that this rainwater is not intended to be used for drinking, cleaning, or other personal purposes.

Be Sure To Check With Local Authorities:

It is recommended that you check with local authorities and your local zoning ordinance and environmental departments before installing a rainwater harvesting system. You'll want to find out about special plumbing requirements, restrictions, neighborhood covenants or other guidelines you may have to follow. These systems must be maintained and located entirely within your property boundaries and should be shielded from view of adjacent properties.
