Capturing Waters Value

• Water is a finite resource
• Storm drain runoff is robbing us of much of our
  freshwater sources
• 14 of the nations water supply is lost through
  water main leaks
• Worldwide consumption is rising at double the
  population growth rate

Why Harvest Rainwater?

• Save money on utility bills
• Reduce non-point source pollution
• Reduce reliance on aging water infrastructure
• Conserve energy

Summary

• RWH has many applications
• RWH can supply a water source, while reducing
  stormwater runoff
• Each RWH system is custom made for the building
  site

Unlike water, the possibilities are infinite
