Introduction• Ground water is 81-100% source of all drinking
water on the Eastern Shore.• Demand for water is expected to increase by
more than 20% between 2000 and 2030.• Water Use Permits:– Maryland and Virginia: greater than 10,000
gallons/day– Delaware: greater than 50,000 gallons/day
University of Maryland Extension
Introduction• Bird water consumption is somewhat easy to
predict.• Evaporative cooling system is harder to
predict.

Introduction• Flock water usage varies depending on a many
factors.– Age of bird– House density– Outside temperature and relative humidity– Type of cooling system– Evaporative cooling set temperatures
University of Maryland Extension
Introduction• University of Georgia monitored water usage
of a 50 ft X 560 ft broiler house in Athens, GA (Czarick and Fairchild, 2009).
• Evaporative cooling system used between 40,000 and 45,000 gallons during the summer.
• Evaporative cooling system used between 10,000 and 20,000 gallons during the spring.
University of Maryland Extension
Background of Study
• Water meters were placed on evaporative cooling pad system (recirculation system) of 15 broiler houses.
• Drinker consumption data also collected (10 houses).
• Data collection started April 2008.• Flocks were placed at various times
throughout the study.
University of Maryland Extension
Background of Study
• Average house size: 29,708 ft2
• Average broiler capacity: 40,057 birds• Average flock age: 52 days• Assume 5 ½ flocks/year = 286 production days
(52 days X 5.5 flocks)
University of Maryland Extension
Results (7/2009)• Average gallons of water used by evaporative
cooling pad system for one flock:– 533 gallons/day/house
• Average gallons of water consumed for one flock: – 1,598 gallons/day/house
• Therefore total gallons used/day/house for one flock = 2,131 gallons/day/house
University of Maryland Extension
Results (7/2009)• Estimated total gallons used for 5 ½ flocks
(286 days) in one house = – 609,466 gallons (286 d X 2,131 gallons)
• Average gallons used per day in one house for 1 year (365 days) = – 1,670 gallons (609,466 gallons ÷ 365 days)
• Average gallons per ft2 =
– 0.0562 gallons/ft2 (1,670 gallons ÷ 29,708 ft2)

How much water do I use on my farm per
year?• Example: – Five houses (33,600 ft2)– Total ft2 = 168,000 ft2 (33,600 ft2 X 5 houses)– Total average gallons used/day = • 9,442 gallons water/day (168,000 ft2 X 0.0562 gallons/ft2)
