Water district rules, zone scheduling, backflow requirements & costs
Florida has 5 Water Management Districts. Select your county to find your district's watering schedule, restrictions, and backflow requirements.
Most FL water utilities issue a written warning on first violation with correction required within 24 hours. Violation documented in utility records.
Most FL utilities: $100-$250 fine plus service fee. Some municipalities increase to $500 for flagrant violations (watering during rain event).
Escalating fine schedule. Some utilities add a permanent account notation. Continued violations may trigger mandatory irrigation audit.
During declared drought emergencies, FL utilities can issue $500-$1,000 fines per incident and may disconnect water service for repeat offenders.
Selecting the right head for FL's sandy soil, high ET (evapotranspiration), and water restriction schedule is key to compliance and turf health.
Slow-rotating stream applies water slowly β better FL clay-over-sand infiltration. Less runoff on compact soils. Matched precipitation rate (MPR) rotors recommended for odd-shaped FL lots. Rain Bird 5000, Hunter PGP, and Orbit common FL installs.
High precipitation rate β prone to runoff on FL's sandy slopes. Use MPR nozzles (matched precipitation rate) and keep run times short (8-10 min). Good for small turf areas, beds, and tight zones. Avoid on slopes > 5%.
Rotating stream applies at 3-4x slower rate than standard sprays. Dramatically reduces runoff on FL's sandy and shell-limestone soils. Many FL water districts offer rebates for conversion from spray to MP Rotators. SWFWMD rebate available.
Drip irrigation applies water directly to root zone β no evaporative loss. FL statutes exempt hand-held hoses and drip/micro-irrigation from day/time watering restrictions. Ideal for FL vegetable gardens, fruit trees, shrubs. Reduces water use 30-50% vs spray.
Saturate root zone of newly planted FL trees and palms. FL's sandy soil requires deep, infrequent watering for tree establishment. Bubblers combined with 3-4" mulch layer reduce irrigation by 25%. Drip exempt from FL watering restrictions.
Florida law (FS 373.62) requires all automatic irrigation systems installed after May 1, 1991 to have a rain sensor (rain shutoff device) installed and functioning. Rain sensors must be tested at each irrigation service call. Smart ET controllers also qualify and are preferred.
| Zone Type | FL Recommended Run Time | Frequency | Best Time |
|---|---|---|---|
| St. Augustine turf | 20β35 min (rotors) | 2x/week max | 4β8am |
| Bahia grass | 15β25 min (rotors) | 1β2x/week | 4β8am |
| Zoysia / Bermuda | 15β20 min (rotors) | 1β2x/week | 4β8am |
| Shrub / Planting beds | 10β15 min (spray) | 2β3x/week | 4β8am |
| Annual flowers | 8β12 min (spray) | 3β4x/week | 4β8am |
| Trees / Palms (drip) | 20β40 min (drip) | 1β2x/week | Any (exempt) |
| Vegetable garden (drip) | 15β30 min (drip) | Daily if needed | Any (exempt) |
FL summer: reduce run times 20-30% β high humidity and daily rain events reduce irrigation need. Dry season (NovβApr): increase as needed within restriction schedule. Check county ET data from UF/IFAS or your utility's website.
