1. Urban Rainwater
Catchment
Native Buffalo Grass, 6” tall max

3. Mission
● Build a healthy, sustainable New Orleans, one
yard at a time.

4. Nola Rainwater Harvest:
● Bioretention Areas
● Cisterns
● Anatomy of a Rain Barrel
● Why rainwater harvest is important

5. Why rainwater harvest in NOLA?
● NOLA is the third rainiest city in the 48 contiguous states
● 65 inches of rain/year
● Our rain comes down all at once
● Water is a universal solvent, transporting contaminants to
Lake Pontchartrain + wetlands

7. BIO RETENTION
Results:
Retention: ●
●
Reduced need for irrigation
Less water into Storm
System
● Collects runoff ● Clean water
● Recharges Water
Table
● Deep Root Watering
Biomass:
• Wicks H20 via
transpiration
• Removes
contaminants

22. Why Cisterns
●Save Money
●Every 1,000 sq ft of roof: 625

●Avg Nola shotgun roof (1850
sq ft) can collect 1,156.25 gal.
H20
●Save Nola
●Save Nola's Money!
