“Wise water management for a safer and stronger New Orleans”
We are a group made up of organizations who strive to
educate individuals about wise water management for a
safer and stronger New Orleans.

Flooding due to rainfall will cost Greater New Orleans $8 billion
dollars over the next 50 years.

Grey Infrastructure: pipes, canals, pumping stations,
water treatment plants, etc
The S&WB of New Orleans currently accomplishes draining 63,000 acres by utilizing 90
miles of covered canals and more than 80 miles of open canals to convey storm water
runoff to 21 drainage pumping stations.

Green Infrastructure: Green Infrastructure is the use of
plants and trees to manage rainwater and reduce
flooding.

How it Works
Green Infrastructure:
Why it is important
Green Infrastructure and low impact development allows individuals to actively
participate in small scale flood protection through a distributed approach to
managing water. When water is slowed down, held temporarily, and directed
into the soil (infiltrated), it can provide direct benefits on the property.
This approach also reduces the amount of stormwater trying to enter into the
city’s system of pipes until after the peak rains have passed, which reduces the
frequency of street flooding during small scale storm events and also improves
water quality in Lake Pontchartrain and other surrounding water bodies.
Green infrastructure is another tool for flood protection.

Living with Water
Assessing your property
Begin with a sketch showing a general
outline of the property, structures and
other hard surfaces
Locate points where rainwater is
concentrated, such as downspouts and
pipes through curbs or walls, and where
it runs off hard surfaces.
Managing Rainwater on Your Lot
Identify where water can be intercepted
(what opportunities exist to manage on-site)
