Title: Drought,Water Conservation, and Water Supply Augmentation


1
Drought,Water Conservation, and Water Supply
Augmentation
  • Todd C. Rasmussen, Ph.D.
  • Professor of Hydrology Water Resources
  • Warnell School of Forestry Natural Resources
  • The University of Georgia, Athens
  • www.hydrology.uga.edu

2
Drought
  • An extended period of months or years when a
    region is faced with a deficiency in its water
    supply
  • Droughts may by caused by
  • Increased demand, or need, for water
  • Decreased supply, or availability, of water
  • Both factors contribute to our drought
  • Our regions rainfall is below normal
  • Our regions population is growing

Drought Levels
mgd million gallons per day
6
Priority Uses
  • 1. Medical and emergency facilities and emergency
    purposes
  • Such as fire suppression, and the use of water to
    satisfy federal, state, and local public health
    and safety requirements
  • 2. Domestic and personal uses
  • Including drinking, cooking, washing, sanitary
    and health related uses and uses necessary to
    sustain domestic and livestock animals and
    personal food gardens (hand or drip irrigation
    only)
  • 3. Commercial, industrial, and institutional uses
  • 4. Refilling of ponds
  • Which existed prior to the declared drought, and
    only to the level necessary to maintain aquatic
    life within the pond prior to the declared
    drought. Also, hand watering of non-lawn turf
    landscape plants and watering of golf courses
    tees box/green areas
  • 5. Outdoor irrigation
  • Uses such as lawn sprinkling (spray irrigation),
    irrigation of recreational/athletic fields and
    golf course fairways
  • 6. Uses that do not sustain plant, animal, or
    human life, health or well-being and/or directly
    support established ongoing commercial,
    industrial, or institutional activities
  • Such uses include non-commercial and fund-raising
    car washing, filling of decorative water
    features, public fountains, water slides, wading
    pools, and topping off of public and private
    swimming pools

7
Water Conservation Options
  • Goal (e.g., 40 gallons per person per day)
  • Decrease water use where we live, work, and play
  • Personal water use (e.g., 30 gal/day)
  • Bathing, toilets, laundry, food preparation
  • Outdoor water use (e.g., 1 gal/day)
  • Lawns, gardens, fountains, swimming pools, car
    washes
  • Commercial, industrial, and institutional water
    use
  • Air conditioning (cooling water)
  • Dining halls (food and beverages)
  • Laboratories (teaching and research)
  • Hospitality (conferences and hotels)

8
Water Augmentation Options
  • Leak Detection
  • indoor (faucets toilets)
  • outdoor (pipes)
  • Storage (from local lakes)
  • Limited due to small volumes
  • Suitable for irrigation and fire suppression
  • Can be treated in emergencies
  • Groundwater (from wells)
  • Limited due to shallow depth to bedrock
  • Can supply limited quantities
  • Subject to contamination

9
Water Augmentation Options
  • Water Reuse
  • Grey Water
  • Untreated wastewater reused at home
  • Not approved due to health concerns
  • Purple Water
  • Treated wastewater delivered
  • from a central treatment facility
  • Suitable for
  • Outdoor irrigation
  • Some cooling
  • industrial purposes
