Rainwater Harvesting at Washington & Lee
University
A presentation by James McCullum
“At least 36 states are anticipating local, regional, or statewide water shortages by 2013, even under non-drought conditions” -EPA
Common practice by ancient civilizations
Water supply during times of drought
Capture, filter, and store water for later use
Evolving and expanding communities wanted centralized water
Rainwater Harvesting (RWH)
Knowing the collection area to be 85ft by 48ft
Average rainfall in Lexington, Virginia is 40.6 inches
Using this formula we find the potential rainwater harvesting to be:
102,563.72 gallons per year
Why not? Return on initial
investment is not enough The current price of water
does not reflect true cost of water
Educate people about true value of water
Reconnect people to water
How important is water to you?
Small Watershed Grants Program: $77,000 average
grant $16.9 million over 7
years
