Uses of Stored Rainwater

History of Rain Water Harvesting:

Rainwater harvesting (collection and storage) is nothing new. Many of the methods devised to harvest, store, and use water have been with us for thousands of years. In fact, thanks to dwindling aquifer supplies, global climate changes, and increasing demand, water conservation is making a comeback in a big way. In several ways, rainwater and collected grey water (recycled dish, bath, or laundry water) have a
number of advantages over tap water.

Big Improvements = Big Advantages:

Modern rain barrels, cisterns, and other collection devices provide innovative ways to store one of nature’s most fundamental elements. Many people have discovered a novel list of uses for their collected water. Below are some of the great ways in which your rainwater harvest can be used to improve your own personal environment, as well as that of the world.

• Lawns and gardens

  • The absence of minerals in rainwater enables gardens, lawns, and houseplants to absorb moisture more efficiently, and as a result, require less water to maintain healthy growth.
    • Secondary water supply
  • Because the salts and minerals commonly found in tap water are absent, harvested rain water provides a great supply of soft water for washing cars, boats, windows, and even clothes.
    • Saves money
    – As Benjamin Franklin said many years ago: “A penny saved is a penny earned”. Lawn and garden watering make up nearly 40% of total household water use during the summer. Consider that a 1000-square-foot catchment area yields 600 gallons per inch of rainfall. At that rate, pennies quickly turn into dollars.
    • Relieves environmental stress
  • Helps reduce the burden on fresh-water sources such as rivers, streams, and aquifers by reducing fresh water demand.

Incentives for Installing a Rainwater Collection System

Installing a rainwater harvesting system to temporarily store and reuse rainwater can reduce your total water use by providing a water source for your lawn and garden. This can reduce both your water-use charge and corresponding sewer charge on your municipal water bill.

What is the Average Rainfall Where You Live?

Rain that runs off your roof can flow into a sewer pipe, stream or groundwater. Why not put this water to another use? A simple rainwater collection system can capture some of that rainfall for later use on your property.

Capturing and reusing rainwater from your roof surfaces also reduces demand on the sewer system, and protects the quality of streams and groundwater.
