factors continued
Determination of how water can betransported to the new use
Evaluation of water quality degradationresulting from the use
Determination of treatment steps that mightbe required to prepare for the water recycling

BEHAVIORAL PRACTICES
MONITORING
-provides baseline information on
qualities of overall company water use, theseasonal and hourly patterns of water use,and the quantities and quality of water use inindividual processes.

1. FIELD PRACTICES
-techniques that keep water in the
field, distribute water more efficiently acrossthe field, or encourage the soil moisture
e.g.
Chiseling of extremely compacted soils;
furrow diking to prevent runoff & leveling theland to distribute water more evenly
ENGINEERING PRACTICES

9/15
2. MANAGEMENT STRATEGIES
- monitoring soil and water conditions
and collecting information on water use andefficiency
Mgt. Strategies: measuring rainfall,determining soil moisture, checking pumpingplant efficiency and scheduling irrigation

3. SYSTEM MODIFICATION
-making changes to an existing
irrigation system or replacing an existingsystem with a new one (*require purchase ofequipment)
Typical system modifications: adding droptubes to center pivot system, retrofitting awell with a smaller pump, installing surgeirrigation, or constructing a tailwaterrecovery system

BEHAVIORAL PRACTICES
Behavior Changes in Agricultural waterusers can be applied to irrigation applicationrates and timing (may be without modifyingexisting equipment).
e.g.
Better Irrigation Scheduling and,
Careful choice of irrigation application rates& timing

ENGINEERING PRACTICES
Plumbing. Replacement of existing plumbingequipment that uses less water (Low-FlowPlumbing Fixtures)
e.g.
Low flush toilets, Faucet Aerators, pressurereducing valves, low flow showerheads Toiletdisplacement devices & Gray water use
8/2/2019 Lolit Japan Presentation 2
14/15
BEHAVIORAL PRACTICES
Use of dishpan with water rather than running the
water continuously Turning off faucet while brushing teeth, shaving or
soaping
Adjusting water level of washing machine to matchthe size of load
Turning off hose in between rinses while washingthe cars.
Cover swimming pools while not in use
Sweeping sidewalks instead of hosing
