Introduction

  • About to start last semester at

University of Wisconsin-Madison

  • Engineering student with focus
  • n water resources
slide-3
SLIDE 3

Bailey Background

  • Large whole sale plant

nursery

  • Farms in Minnesota,

Illinois, Washington, Oregon, and Georgia

slide-4
SLIDE 4

Nord Farm: Recycling Water for Irrigation Container East: Optimizing Irrigation

slide-5

SLIDE 6

Why Change?

  • Located in North and East Groundwater

Management Area

  • Identified as a large groundwater user
slide-7
SLIDE 7

Nord Farm

slide-8
SLIDE 8

Goal: Reduce amount of groundwater used for irrigation by utilizing pond water

slide-9
SLIDE 9

Background

  • 54 million gallons

consumed in 2016

  • Pump from west

pond

  • 6.5 million gallons

Irrigation

  • Greenhouses

connected by drainage tiles

  • Seedbeds

drain to East pond

slide-11
SLIDE 11

Rainfall

  • Water ends up

in drain or pond

  • Gutters on

greenhouses send it directly to pipes

slide-12
SLIDE 12

Rainfall in the Seedbeds

  • 75% drains to

the East pond

slide-13
SLIDE 13

Reducing Sediment in Pipes

  • Prevent and remove

sediment in pipes

  • Drainage berm will

reroute the rainfall away from problem area

slide-14
SLIDE 14

Drainage Berm

  • Directs water

towards East Pond

  • Reduces sediment

and rock in pipes

slide-15
SLIDE 15

New Drainage Berm at Work

slide-16
SLIDE 16

Water Conveyance to West Pond

  • Gate prevents backflow

into East pond

  • Becomes settling pond

for water from seedbeds

  • Water is pumped into

pipe connecting East and West ponds

slide-17
SLIDE 17

Water Availability from Different Areas Around Nord

Greenhouses

  • 85% of rainwater is recoverable
  • 22 million gallons of water available/year

Seedbeds

  • 35% of rain and irrigation water is recoverable
  • 10 million gallons of water available/year

Roads, Buildings, etc

  • 55% of rainwater is recoverable
  • 21 million gallons of water available/year

Piping

  • Underground

to first greenhouse

  • Sent through

Production to holding tank

Recommendations

Trial Result Ideal Recommendation Water Holding Capacity 28% 45-65% Change substrate to have higher water capacity Plant Available Water 44% > 25% No Change Sprinkler Irrigation Uniformity 84% > 80% No Change Irrigation Capture Factor Cones = 98% < 100% Might need to water more Roses = 112% > 100% Might be able to water less Leaching Fraction 1 gallon = 29% 10-15% Can water less frequently 2 gallon = 10% 10-15% Might need to water more

Potential Savings

  • 10 million gallons
  • More if further steps are taken
slide-32
SLIDE 32

Conclusion

  • Annual water

savings of 38 million gallons at Nord Farm

  • 10 million gallons

at Container East

slide-33

Personal Benefits

  • Gather data from a variety of places
  • Independent and team work
