Need
quantitative
data FFL Water Savings Table Survey was developed based upon this metricSlide3
Water savings table
Objective: Develop measurable metric for impact of FFL practices adopted by residential water customersSlide4

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 savingsSlide10
2. Calibrate sprinklers to ½” or ¾”
EDIS Publication ENH63 recommends ½”-¾” per irrigation event25% reduction= 7,942 gal/ 1,000 sqft savings
50% reduction= 15,884 gal/ 1,000 sqft savingsSlide11
3. Calibrate sprinklers to
replace 60% of ETEDIS Publication AE436 indicates 60% ET replacement generally adequate
40% reduction= 12,707 gal/ 1,000 sqft savingsSlide12
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 sqftSlide13
5. Convert turfgrass to landscape bed
EDIS Publication ENH860 recommends ornamental plants irrigated only as needed after establishmentMicroirrigation: 48% reduction in irrigation
100% reduction= 31,787 gal/1,000 sqft savings
48% reduction= 15,589 gal/1,000 sqft savingsSlide14
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

7. Convert spray heads to MSMTs
Multi-stream multi-trajectory nozzles typically have greater uniformity and have lower flow rates67% reduction=
21,191 gal/1,000 sqft
