Spring Hill FL Water Restrictions 2026

Current water restrictions in Spring Hill, Florida

Spring Hill is under Modified Phase III — Extreme Water Shortage restrictions declared by the Southwest Florida Water Management District (SWFWMD), limiting outdoor irrigation to one day per week with narrowly defined overnight hours.

SWFWMD declared the Modified Phase III restriction effective April 3, 2026, covering Spring Hill, all of Hernando County, and more than 11 counties across the Tampa Bay region. The trigger was a regional rainfall deficit of 13.7 inches below the 12-month average — one of the most severe shortfalls recorded in this area in nearly a decade. Aquifer levels, river stages, and lake elevations throughout Hernando County are at severely abnormal readings, prompting the first Phase III declaration since 2017.

Spring Hill draws its water from the Upper Floridan Aquifer, a confined limestone aquifer that recharges slowly. Thirteen-plus inches of missing rainfall over a full year has depressed aquifer pressure significantly, reducing yield at municipal wellfields that serve Hernando County Utilities customers across Spring Hill.

SWFWMD holds authority over water use permits and shortage declarations under Chapter 373, Florida Statutes. At the state level, SWFWMD's Phase III designation is the second-most severe tier in its four-phase framework, and it carries mandatory rather than voluntary cutbacks.

Practically, this means a Spring Hill resident with a street address ending in 4 or 5 may run their irrigation system only on Wednesday, and only during the windows of 12:01 AM–4:00 AM or 8:00 PM–11:59 PM — not both windows in the same day if the property is under one acre. Watering a vegetable garden on a Wednesday morning at 9:00 AM is a citable offense carrying a $500 fine, with no warning issued.

Watering schedule and allowed days

Your assigned watering day is determined by the last digit of your property's street address number. A home at 7142 Crestridge Drive ends in 2, so Tuesday is the only permitted irrigation day. A home at 3309 Mariner Boulevard ends in 9, making Friday the assigned day. This applies to both residential and commercial accounts served by Hernando County Utilities.

Under Modified Phase III, properties smaller than one acre — which includes the vast majority of Spring Hill's residential lots — are restricted to one watering window per scheduled day, not both. You may choose either the late-night window (12:01 AM–4:00 AM) or the evening window (8:00 PM–11:59 PM), but running irrigation in both windows on the same day violates the restriction. Properties larger than one acre follow the same day assignment but may use both windows.

New lawn installations and sod replacements are prohibited during Phase III without a SWFWMD-issued variance. Contact SWFWMD at 1-800-836-0797 to apply. If you have recently planted live oak (Quercus virginiana), Southern magnolia (Magnolia grandiflora), or sabal palm (Sabal palmetto) — all common in Hernando County landscaping — hand watering with a shut-off nozzle is permitted any day to support establishment, as drip lines and hand watering are exempt from the day and hour restrictions.

What happens if you violate restrictions in Spring Hill?

SWFWMD and Hernando County Utilities both have authority to issue citations. Enforcement shifted to zero-tolerance on April 17, 2026 — there is no warning period, no grace notice, and no first-offense courtesy knock. Each separate watering event observed outside permitted days or hours constitutes an individual violation. A system that runs three zones outside the allowed window could be treated as a single event or multiple events depending on inspector discretion and the duration observed.

Violations can be reported directly to SWFWMD's water shortage hotline at 1-800-836-0797 or through the district's online complaint form at swfwmd.state.fl.us/residents/water-restrictions. SWFWMD inspectors and county utility personnel patrol actively during peak violation hours — particularly the early morning and early evening windows that fall just outside the permitted 8:00 PM start. Complaints from neighbors trigger follow-up field inspections, typically within 24–72 hours. An appeals process exists through SWFWMD's administrative hearing procedures under Chapter 120, Florida Statutes, but fines are not automatically stayed during appeal.

Other outdoor water rules

Phase III restrictions extend beyond lawn irrigation. The following rules apply to Spring Hill and all Hernando County properties under the SWFWMD Modified Phase III declaration:

• Reclaimed water irrigation: Reclaimed water systems are subject to a two-day-per-week schedule under Phase III rather than the one-day potable limit — check with Hernando County Utilities for your specific reclaimed account assignment.
• Vehicle washing: Prohibited except at commercial car washes that recycle water, or using a bucket-and-shutoff-nozzle method that prevents runoff.
• Swimming pool filling and topping off: Permitted only to replace evaporation loss — filling a new or drained pool requires a variance from SWFWMD.
• Pressure washing: Restricted to health and safety necessity only; aesthetic cleaning of driveways and pavers is not permitted.
• Decorative fountains and water features: Must be turned off unless they operate on a fully recirculating system with no water discharge.
• Construction site irrigation and dust control: Requires documentation and is subject to SWFWMD review; unnecessary flushing is prohibited.
• Restaurant water service: Water served to diners only upon request — this remains in effect statewide under Florida's permanent water conservation rule.

Water source and infrastructure

Spring Hill's municipal water supply comes entirely from the Upper Floridan Aquifer, a regionally extensive, confined limestone aquifer that underlies all of Hernando County and much of the Florida peninsula. Hernando County Utilities operates a network of production wellfields — including wellfields in the Spring Hill service area — that pump directly from the Upper Floridan to serve approximately 60,000 residential and commercial accounts across the county.

The Upper Floridan Aquifer recharges through rainfall percolating through the sandy soils of the Brooksville Ridge and adjacent flatlands. It is not a fast-responding system. A 13.7-inch rainfall deficit accumulated over 12 months translates to meaningfully reduced aquifer pressure, lower static water levels in monitoring wells, and reduced yield from production wells. SWFWMD monitors aquifer levels continuously across Hernando County and uses those readings — alongside lake stage and river flow data — to determine water shortage phase triggers.

The Weeki Wachee River, which originates from Weeki Wachee Springs State Park just south of Spring Hill in Hernando County, is one of the most direct visible indicators of aquifer stress in this area. Spring flow from the Weeki Wachee main spring is fed by the same Upper Floridan system supplying municipal wells — when aquifer levels drop, spring discharge drops with it. During the current drought, Weeki Wachee spring flow has measurably declined from its historical average of approximately 117 million gallons per day.

Hernando County Utilities does not operate a surface water treatment plant or desalination facility. The county has no connection to the Tampa Bay Regional Desalination Plant in Apollo Beach, which serves Hillsborough and portions of Pinellas County. Spring Hill is entirely dependent on the Upper Floridan Aquifer, making local recharge conditions and aquifer health directly tied to every Phase III restriction decision SWFWMD issues.

Brown lawn protections in Florida

Florida law protects Spring Hill homeowners from HOA fines and enforcement actions related to lawn browning caused by mandatory water restrictions. Florida Statutes § 720.3075 prohibits homeowners' associations from requiring members to maintain landscaping in a manner that conflicts with a water shortage order or a local government irrigation ordinance. During an active SWFWMD Phase III restriction, your HOA cannot fine you, cite you, or threaten enforcement for a lawn that goes dormant or browns due to the one-day-per-week watering limit.

This protection applies as long as the water shortage order is in effect — currently scheduled through July 1, 2026. Once SWFWMD lifts or reduces the restriction, normal HOA landscape standards resume. Document the SWFWMD Phase III declaration date (April 3, 2026) and keep a copy of any HOA communication you receive.

If your HOA issues a violation notice for a brown lawn during the current Phase III restriction, use this template response:

"This notice is issued in error. My property is located within the Southwest Florida Water Management District (SWFWMD) service area, which is currently under a Modified Phase III — Extreme Water Shortage declaration effective April 3, 2026. Under Florida Statutes § 720.3075, a homeowners' association may not require landscaping maintenance that conflicts with a mandatory water shortage order issued by SWFWMD. Any lawn browning present is a direct result of compliance with the one-day-per-week irrigation restriction. I request this citation be rescinded immediately. I am prepared to file a complaint with the Florida Department of Business and Professional Regulation (DBPR) if this matter is not resolved."

Lawn care during restrictions

Spring Hill's warm, humid climate supports warm-season turfgrasses. The following table summarizes how the four most common local grass types are handling Phase III conditions:

Spring Hill's sandy Hernando County soils drain quickly, which accelerates moisture loss between watering days. On your assigned watering day, run irrigation long enough to deliver ½ to ¾ inch of water per zone — use a tuna can or rain gauge to measure output. Applying water during the 12:01 AM–4:00 AM window minimizes evaporation and wind loss compared to any daytime watering scenario. Raise your mowing height to 3.5–4 inches for St. Augustine and Zoysia to shade root zones and slow soil moisture loss; Bahia tolerates a slightly lower cut at 3 inches.

Florida's high humidity creates active conditions for gray leaf spot and brown patch fungus in St. Augustine lawns even during drought stress — drought-weakened turf is more susceptible, not less. Avoid applying nitrogen fertilizer during Phase III; it forces shoot growth the root system cannot support without adequate water and increases fungal pressure. Hold all fertilizer applications until restrictions are lifted and the lawn has resumed active growth. If you must treat fungal issues, do so with a targeted fungicide application on your assigned watering day.

Common questions about Spring Hill water restrictions

What day can I water at my Spring Hill address?

Your watering day is determined by the last digit of your street address number. Addresses ending in 0 or 1 water on Monday; 2 or 3 on Tuesday; 4 or 5 on Wednesday; 6 or 7 on Thursday; 8 or 9 on Friday. For example, a home at 4836 Clubhouse Road ends in 6, so Thursday is the only permitted irrigation day. You may water during 12:01 AM–4:00 AM or 8:00 PM–11:59 PM — but if your property is under one acre, pick only one of those windows per day.

What happens if I water outside my assigned day or hours?

You will receive a $500 citation with no prior warning. SWFWMD moved to zero-tolerance enforcement on April 17, 2026. There is no courtesy notice, no orange door hanger, and no first-offense warning under Modified Phase III. Citations are issued on the spot by SWFWMD inspectors or Hernando County Utilities personnel.

When are the current Phase III restrictions scheduled to end?

SWFWMD has set a review and expected rollback date of July 1, 2026, which aligns with the start of Florida's traditional wet season. However, restrictions can be extended if the rainfall deficit persists or reduced early if significant rainfall events improve aquifer levels and lake stages across Hernando County. Check SWFWMD's restrictions page at swfwmd.state.fl.us/residents/water-restrictions or call 1-800-836-0797 for current status before that date.

Can I water my vegetable garden or potted plants on off days?

Yes — hand watering with a shut-off nozzle is exempt from the day and hour restrictions under Phase III. You can use a watering can or a hose with a trigger-style shut-off nozzle to water vegetable beds, container plants, or individual shrubs any day of the week. The exemption does not cover running a hose without a shut-off device or using any automated or semi-automated irrigation on off days.

Is drip irrigation restricted to my assigned watering day?

No. Drip and micro-irrigation systems that apply water directly to the root zone without overspray are exempt from the day and hour schedule under SWFWMD's Phase III rules. This means a drip-irrigated vegetable garden, raised bed, or planting bed can run any day. This exemption is one practical reason to convert overhead spray zones in landscape beds to drip emitters — it's permitted immediately and avoids scheduling conflicts entirely.

Does SWFWMD use smart meters or remote monitoring to catch violations?

Hernando County Utilities has been expanding automated meter infrastructure (AMI), which logs usage intervals. Unusually high water consumption during off-hours or off-days can flag an account for field follow-up. However, the primary enforcement mechanism remains visual patrol by inspectors and neighbor complaints submitted to SWFWMD's hotline. Patrols are concentrated in the early evening hours just before the 8:00 PM window opens, when violations are most commonly observed.

Can I fill or top off my swimming pool during Phase III?

You may add water to an existing pool to replace evaporation loss — this is permitted under Phase III. Filling a newly constructed or recently drained pool is a different matter and requires a variance from SWFWMD before proceeding. Given Spring Hill's summer heat and the current aquifer stress, SWFWMD scrutinizes large-volume draws carefully. Contact the district at 1-800-836-0797 before emptying and refilling a pool for any reason during the current restriction period.

What rebate or turf-removal programs does SWFWMD offer Spring Hill homeowners?

SWFWMD administers the Florida-Friendly Landscaping incentive program and partners with Hernando County on turf replacement and irrigation efficiency rebates. The district's WaterStar program certifies water-efficient irrigation contractors and landscapes. Rebate availability and funding levels change annually — visit swfwmd.state.fl.us or call 1-800-836-0797 to confirm what is currently funded for Hernando County properties. Converting St. Augustine lawn areas to mulched native plant beds reduces your irrigation load permanently and insulates you from future Phase III restrictions.

What days can I water my lawn in Spring Hill?

0 or 1: Monday; 2 or 3: Tuesday; 4 or 5: Wednesday; 6 or 7: Thursday; 8 or 9: Friday Hand watering with a shut-off nozzle is typically allowed any day during permitted hours.

What time can I water in Spring Hill?

Watering is allowed 12:01 AM – 4:00 AM and 8:00 PM – 11:59 PM. Watering outside these hours is a violation even on your assigned day.

What are the fines for watering violations in Spring Hill?

First offense: $500. Repeat violations: No warnings — citations issued immediately starting April 17, 2026. Up to $500 per violation.. Contact SWFWMD for the full enforcement schedule.
