  5. Agriculture, Industry and Household Needs • Irrigation techniques- • Furrow irrigation- a trench that is flooded with water. • Flood irrigation- the entire field is flooded with water. • Spray irrigation- an apparatus that sprays water across a field. • Drip irrigation- using a slow dripping hose that is laid on or buried beneath the soil. • Hydroponic agriculture- crops grown in fertilized water and no soil.

  6. Agriculture, Industry and Household Needs • Industry- the second largest user of water worldwide.

  7. Agriculture, Industry and Household Needs • Households- the third largest user of water worldwide .

  8. The Future of Water Availability • Water ownership- people can have rights to water use, but they do not own the water. • Water conservation- using techniques such as more efficient water fixtures, faucets and washing machines.
