  1. Florida-Friendly Landscaping™ (FFL) Irrigation System Survey Claire Lewis & Mackenzie Boyer

  2. Why we developed this set of survey instruments Need quantitative data FFL Water Savings Table Survey was developed based upon this metric

  3. Water savings table Objective: Develop measurable metric for impact of FFL practices adopted by residential water customers

  4. Irrigation Requirements Estimation 1” = 623 gal/1,000 sqft Turfgrass Annual Water Req. N FL, 33 inches/yr S FL, 43 inches/yr =3,700 gal/1,000 sqft

  5. Irrigation run time recommendations: EDIS Publication AE220 Average = 29.4 min event-1

  6. Baseline irrigation case

  7. Distribution of customers 35,000 Theoretical limit = 77 mm month-1 (3.0 in month-1) 28,000 21,000 Number of customers Baseline case = 108 mm month-1 (4.25 in month-1) 14,000 7,000 400 430 460 More 370 310 340 10 220 130 160 190 250 100 280 70 40 Estimated irrigation (mm month-1)

  8. Distribution of customers 35,000 28,000 Pinellas County = 64 mm month-1 (4.25 in month-1) 21,000 Number of customers Baseline case = 108 mm month-1 (4.25 in month-1) 14,000 Orange County = 149 mm month-1 (5.87 in month-1) 7,000 400 430 460 More 370 310 340 10 220 130 160 190 250 100 280 70 40 Estimated irrigation (mm month-1) Sources: Pinellas County: Haley and Dukes 2012 Orange County: Haley and Dukes 2007

  9. 1. Rain sensor • Savings based on plot study of 5 types of rain sensors and IFAS-recommended irrigation settings • 8% reduction= 2,541 gal/ 1,000 sqft savings

  10. 2. Calibrate sprinklers to ½” or ¾” • EDIS Publication ENH63 recommends ½”-¾” per irrigation event • 25% reduction= 7,942 gal/ 1,000 sqft savings • 50% reduction= 15,884 gal/ 1,000 sqft savings

  11. 3. Calibrate sprinklers to replace 60% of ET • EDIS Publication AE436 indicates 60% ET replacement generally adequate • 40% reduction= 12,707 gal/ 1,000 sqft savings

  12. 4. Smart controllers • ET controllers: 41-43% reduction • Soil moisture sensors: 35-72% reduction • 35% reduction= 11,118 gal/ 1,000 sqft • 72% reduction= 22,872 gal/ 1,000 sqft

  13. 5. Convert turfgrass to landscape bed • EDIS Publication ENH860 recommends ornamental plants irrigated only as needed after establishment • Microirrigation: 48% reduction in irrigation • 100% reduction= 31,787 gal/1,000 sqft savings • 48% reduction= 15,589 gal/1,000 sqft savings

  14. 6. Rain barrels • Irrigation savings for turfgrass from using of 55-gal rain barrel was simulated • 6% reduction= 1,906 gal/1,000 sqft savings fyn.ifas.ufl.edu/barrels.htm

  15. 7. Convert spray heads to MSMTs • Multi-stream multi-trajectory nozzles typically have greater uniformity and have lower flow rates • 67% reduction= 21,191 gal/1,000 sqft www.turfmagazine.com/content/TF/2013/04/A9379_1_full.jpg

  16. There are 3 survey instruments in this set • The FFL Irrigation System Survey • Intended to be given prior to FFL workshop • FFL Knowledge gain Survey • Intended to be given after FFL workshop • Irrigation System Follow-up Survey • Intended to be given 6-12 months after FFL workshop

  17. What is Qualtrics • Web-based survey system • Logic based Interactive questions • Data can be analyzed as it is collected • Can be exported to PowerPoint, Word, Excel, or PDF • lynda.com - online training library

  18. How administered • Online through Qualtrics • Agents • MG 

  19. Who is the survey intended for • Homeowners who have an in ground irrigation system

  20. What are the benefits to the agents to use • Clear, consistent and measurable reporting tool • SMART objective • Next steps • fertilizer • pest management • We are now going to go through the survey
