FloridaFriendly Landscaping FFL Irrigation System Survey Claire Lewis

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

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

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

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

Irrigation run time recommendations: EDIS Publication AE 220 Average = 29. 4 min event-1

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

2. Calibrate sprinklers to ½” or ¾” • EDIS Publication ENH 63 recommends ½”-¾” per irrigation event • 25% reduction= 7, 942 gal/ 1, 000 sqft savings • 50% reduction= 15, 884 gal/ 1, 000 sqft savings

3. Calibrate sprinklers to replace 60% of ET • EDIS Publication AE 436 indicates 60% ET replacement generally adequate • 40% reduction= 12, 707 gal/ 1, 000 sqft savings

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

5. Convert turfgrass to landscape bed • EDIS Publication ENH 860 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

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

7. Convert spray heads to MSMTs • Multi-stream multitrajectory 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/A 9379_1_full. jpg

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
