The benefits of rainwater harvesting go beyond reducing water costs. Attain LEED credits through the US Green Build Council.
Below you will find information on how rainwater harvesting can help with LEED Accreditation.
Reduce energy demands
Using harvested rainwater for non-potable needs requires less energy than municipally supplied water, which uses large amounts of energy through water treatment and distribution processes.
Promote green technologies and water conservation
Reduce stormwater runoff and non-point source pollution
- Reduce stormwater fees
- Reduce detention pond areas
- Increase usable green space
- Utilize land more efficiently for buildings
- Protect sensitive waterways
Reuse water onsite for nonpotable demands such as:
- landscape irrigation
- green roof irrigation
- pool or pond filling
- vehicle washing
- fleet vehicles
- emergency vehicles: fire trucks, police cars, ambulances
- toilet flushing
- clothes washing
- fire suppression
- cooling towers
Provide a water supply in areas where groundwater is diminished and/or municipal water supply is not available.
Provide an onsite safe water supply during natural disasters and terrorist attacks.
Allow for irrigation during times of drought, which promotes plant health and reduces the heat island effect and subsequent energy demands around buildings.
Collect water during heavy rains, which cannot be absorbed into ground, and reapply at the appropriate infiltration rate, encouraging plant growth and reducing stormwater runoff.
Recharge groundwater aquifers with collected rainwater.
