Different Components of Rainwater Harvesting System

Basic Components: Regardless of the complexity of the system, the domestic rainwater harvesting system comprises six basic components:

#1 Catchment surface: the collection surface from which rainfall runs off
#2 Gutters and downspouts: channel water from the roof to the tank
#3 Leaf screens, first-flush diverters, and roof washers: components which remove debris and dust from the captured rainwater before it goes to the tank
#4 One or more storage tanks, also called cisterns
#5 Delivery system: gravity-fed or pumped to the end use
#6 Treatment/purification: for potable systems, filters and other methods to make the water safe to drink.

Rainwater harvesting is the capture, diversion, and storage of rainwater for a number of different purposes including landscape irrigation, drinking and domestic use, aquifer recharge, and stormwater abatement.

In a residential or small-scale application, rainwater harvesting can be as simple as channeling rain running off an unguttered roof to a planted landscape area via contoured landscape. To prevent erosion on sloped surfaces, a bermed concave holding area down slope can store water for direct use by turf grass or plants. More complex systems include gutters, pipes, storage tanks or cisterns, filtering, pump(s), and water treatment for potable use.

This blog focuses on residential or small-scale commercial systems, for both irrigation and potable use. Further reading: http://www.rwh.in/RainwaterHarvestingManual_3rdedition.pdf

The local health department and city building code officer should be consulted concerning safe, sanitary operations and construction of these systems.

Garden Water Saver

Why Collect Rainwater for the Garden.
How to Make a Rain Barrel in 5 Easy Steps.

Garden Water Saver allows environmentally conscious people to easily collect rainwater from the roof of a house, so that the water can be used whenever it’s needed to irrigate a lawn or a garden, to clean yard tools, or for any other non-drinking use.

Garden Water Saver allows environmentally conscious people to easily collect rainwater from the roof of a house, so that the water can be used whenever it’s needed to irrigate a lawn or a garden, to clean yard tools, or for any other non-drinking use.

Plants, flowers and vegetables love rainwater from the sky, which means they also love rainwater from the rain barrel!
Soft, pure, chemical-free rainwater maintained at proper ambient temperature help plants grow vigorously.

But collecting rain water for a garden without a rainwater harvesting system can be a bit unwieldy. The easiest way to get rain water from your roof to your rain barrel is to use a diverter right in your gutter’s downspouts. By placing a Garden Watersaver Downspout Diverter directly into your roof’s gutter system, you’ll have a rain barrel full of natural rain water in no time, making it easy to water your garden the eco-friendly way!

The secret of Garden Watersaver is their unique Downspout Diverter, which attaches easily to any gutter’s downspout. Once in place, the Diverter sends water to a rain barrel through a hose until that barrel is completely full. Once full, additional water simply continues down the downspout as it normally would — so the process is automatic!

Garden Watersaver also offers a Complete Rain Barrel Construction Kit that includes the Downspout Diverter plus all of the other items and instructions necessary to build a complete rain barrel system for water collection. It’s all there!

The amount of rainfall that you can collect is governed by the following formula: Easy to Remember Formula: 1″ of rain x 1 sq. ft. = 0.623 gallons To calculate the amount of rainwater you can collect, you need to know your annual average precipitation for your area. You can use the precipitation map from search engine to find approximate amount for your area.

WHY COLLECT RAINWATER FOR THE GARDEN?
The primary purpose of a rain garden is to reduce runoff, so it should be placed in a location enabling the garden to collect water. Select only native plants (shrubs, perennials, and annuals) for your rain garden.
