Rainwater harvesting systems are simple to install, operate, and maintain. It is convenient in the sense that it provides water at the point of consumption and operating costs are negligible. Water collected from the roof catchment is available for use in potable (per local approval) and non-potable applications.

Rainwater Harvesting Products, Residential and Commercial Applications Overview

  1. 1. Rainwater Harvesting Residential & Commercial Applications Ed Crawford Rainwater Management Solutions Jay R. Smith Mfg. Co. & Rainwater Management Solutions proudly present:
  2. 2. Capturing Water’s Value <ul><li>Water is a finite resource </li></ul><ul><li>Storm drain runoff is robbing us of much of our freshwater sources </li></ul><ul><li>14% of the nation’s water supply is lost through water main leaks </li></ul><ul><li>Worldwide consumption is rising at double the population growth rate </li></ul>
  3. 3. Why Harvest Rainwater? <ul><li>Save money on utility bills </li></ul><ul><li>Reduce non-point source pollution </li></ul><ul><li>Reduce reliance on aging water infrastructure </li></ul><ul><li>Conserve energy </li></ul>
  4. 4. Did you know? <ul><li>One inch of rain on a 1000 sq. ft. roof provides 620 gallons of harvested rainwater? </li></ul><ul><li>As a general rule you can take three times the roof square footage to calculate the maximum storage capacity of a storage tank or cistern? </li></ul><ul><li>A rainwater system along with other sustainable systems can increase the value of a building? </li></ul><ul><li>Storage tanks or cisterns can act as volume control devices? They can help reduce the cumulative effect of stormwater on downstream systems. </li></ul>
  5. 5. How to use Harvested Rainwater? <ul><li>Nonpotable </li></ul><ul><li>Building washing </li></ul><ul><li>Cooling towers </li></ul><ul><li>Fire suppression </li></ul><ul><li>Household cleaning </li></ul><ul><li>Irrigation </li></ul><ul><li>Laundry washing </li></ul><ul><li>Pool/pond filling </li></ul><ul><li>Toilet flushing </li></ul><ul><li>Vehicle washing </li></ul><ul><li>Potable </li></ul><ul><li>Drinking water </li></ul><ul><li>Cooking </li></ul><ul><li>Bathing </li></ul><ul><li>Dish washing </li></ul>
