Biloxi MS Water Restrictions 2026

Current water restrictions in Biloxi, Mississippi

Biloxi is under a Stage 1 Voluntary Conservation Advisory, limiting outdoor irrigation to 3 days per week through December 31, 2026. The advisory was issued by Biloxi Public Works, which manages water service for Biloxi and surrounding communities along the Gulf Coast. You can reach them directly at biloxi.ms.us/publicworks or by phone at 228-435-6270.

The advisory reflects monitoring-level drought conditions across Mississippi's southern corridor. The Mississippi Department of Environmental Quality and regional water managers are tracking rainfall deficits across the Coast; contact Biloxi Public Works directly for the current deficit figure affecting the service area. At the state level, no mandatory restrictions are in force — Mississippi is in a drought monitoring posture, meaning Stage 1 voluntary measures are a proactive step rather than a crisis response.

Because this is a voluntary advisory, there are no fines or enforcement actions at Stage 1. Biloxi Public Works is asking residents and businesses to reduce outdoor water use voluntarily to protect system capacity before conditions require mandatory restrictions. The advisory runs through December 31, 2026, though the stage can be raised or lowered depending on rainfall and reservoir conditions — check the utility website or call for the latest status.

Practically speaking: yes, a resident with an odd-numbered address can water their garden on a Wednesday morning — as long as they finish before 11:00 AM. The midday irrigation window (11:00 AM to 4:00 PM) is specifically discouraged under the advisory due to peak evaporation loss during Gulf Coast afternoons. Irrigation after 4:00 PM is also permitted. Residents with new sod installations should confirm an establishment variance with Biloxi Public Works before starting; a 21-day temporary exemption is typically available.

Biloxi's watering days and hours

Your watering day assignment is based on the last digit of your street address number. If your house number ends in 1, 3, 5, 7, or 9 — you are odd, and your days are Monday, Wednesday, and Friday. If it ends in 0, 2, 4, 6, or 8 — you are even, and your days are Tuesday, Thursday, and Saturday. Sunday is reserved as a no-irrigation day for all residential and commercial accounts.

For multi-family properties and commercial accounts served by Biloxi Public Works, the same address-based assignment applies using the primary civic address of record on the water account. If a commercial campus spans multiple addresses or buildings, the operator should contact Biloxi Public Works at 228-435-6270 to confirm the assigned schedule rather than assuming based on a secondary address.

When planning which plants to prioritize on your allotted watering days, note that established Southern live oaks (Quercus virginiana) — one of the most iconic trees along the Biloxi coast — tolerate brief dry spells but benefit from deep watering during extended gaps between rain events. Satsuma orange trees, widely grown in Harrison County home landscapes, are sensitive to moisture stress during fruit set and should be watered on schedule throughout summer. Crape myrtles (Lagerstroemia indica), planted heavily throughout Biloxi neighborhoods, are relatively drought-tolerant once established but will drop blooms prematurely under water stress in July and August.

Violation fines and enforcement

Because the current advisory is voluntary, Biloxi Public Works is not issuing citations or fines for irrigation schedule violations. The utility relies primarily on community cooperation and self-reporting at Stage 1. If Stage 2 mandatory restrictions are declared, enforcement shifts to active monitoring — including field patrols by Public Works staff and complaint-based investigations triggered by reports from neighbors or utility personnel observing runoff or midday irrigation. At that point, fines would be assessed per the city's water conservation ordinance.

Residents who receive a courtesy notice — even without a fine — should respond promptly. Biloxi Public Works tracks addresses that received notices; repeat appearances on that list can result in a faster escalation to formal enforcement if the stage is raised. If you believe a notice was issued in error (for example, you were using drip irrigation, which is exempt), you can request a review by contacting the utility directly at 228-435-6270 or through the Public Works office portal at biloxi.ms.us/publicworks.

Other outdoor water rules

The Stage 1 advisory focuses primarily on landscape irrigation, but Biloxi Public Works encourages reducing all discretionary outdoor water use. The following activities are addressed under conservation guidelines:

• Vehicle washing: Permitted, but residents are encouraged to use a bucket and shut-off nozzle or visit a commercial car wash that recycles water. Letting a hose run unattended is discouraged.
• Pool filling and topping off: Pools may be filled or topped off, but pool owners are encouraged to use a pool cover to reduce evaporation losses — significant on the Gulf Coast during summer months when pools can lose several inches per week to heat and wind.
• Pressure washing: Permitted for safety or maintenance purposes; avoid routine decorative pressure washing during the advisory period. Allow surface runoff to dissipate before irrigation.
• Ornamental fountains and water features: Voluntary curtailment encouraged for recirculating fountains not equipped with auto-refill; non-recirculating fountains should be turned off.
• Construction water use: Contractors should use recirculated or non-potable sources for dust suppression where available; check with Biloxi Public Works for guidance on permitted construction connections.
• Restaurant and commercial: No specific Stage 1 rules on table water service, but commercial irrigation accounts follow the same address-based schedule as residential accounts.

How Biloxi gets its water

Biloxi's municipal water supply is drawn primarily from the Biloxi Artesian Aquifer system, a series of confined aquifers underlying the Mississippi Gulf Coast. These aquifers — part of the broader Mississippi Coastal Plain aquifer system — provide groundwater that has historically supplied much of Harrison County's municipal and industrial water demand. Biloxi Public Works operates well fields that tap these artesian formations, which sit beneath layers of clay and sand at varying depths along the coastal plain.

The treated water is processed through the city's water treatment facilities before distribution across the service area. Because the primary source is groundwater rather than a surface reservoir, Biloxi's supply is less immediately visible than a lake level dropping during drought — but aquifer recharge rates are closely monitored. Extended dry periods reduce the precipitation-driven recharge that replenishes the confined aquifer system over time, which is why conservation advisories are issued even when no surface reservoir is at a critically low stage.

The Mississippi Department of Environmental Quality (MDEQ) oversees groundwater permitting and monitors aquifer levels across the Coast. MDEQ's Water Permits Division tracks long-term trends in the Biloxi-area aquifer, and their data informs the trigger thresholds that Biloxi Public Works uses when deciding whether to escalate from Stage 1 to mandatory restrictions. The utility also coordinates with the Mississippi State University Extension Service and regional water planning bodies on long-range supply projections for the Harrison County area.

Supplemental surface water from the Tchoutacabouffa River and nearby coastal waterways plays a limited role in the regional water picture, primarily for industrial use rather than municipal drinking water. The Gulf Coast's high humidity and seasonal rainfall — averaging roughly 65 inches per year in Biloxi — normally supports aquifer recharge, but multi-week dry spells during summer can strain system capacity during peak demand months.

HOA and brown lawn protections

Mississippi does not have a specific state statute equivalent to Florida's FS § 720.3075 or Texas's Property Code § 202.007 that explicitly prohibits homeowners associations from fining residents for brown lawns during declared water restrictions. Mississippi HOA governance is generally controlled by each association's recorded covenants, conditions, and restrictions (CC&Rs) and the Mississippi Nonprofit Corporation Act rather than a dedicated HOA water-restriction protection law. That said, most HOA enforcement documents include an exemption clause for conditions caused by compliance with governmental orders — and a Stage 1 advisory from Biloxi Public Works, even though voluntary, provides a reasonable documented basis to push back on a fine.

If your HOA issues a violation notice for a brown or dormant lawn while you are following the Biloxi Public Works Stage 1 advisory schedule, review your CC&Rs for any language referencing compliance with municipal utility requirements or government directives. Document your watering days with photos and timestamps. Then send a written response to your HOA board referencing the advisory.

Sample response: "I am writing to contest the lawn maintenance violation issued on [date]. My property at [address] is subject to the current Stage 1 Voluntary Conservation Advisory issued by Biloxi Public Works (228-435-6270; biloxi.ms.us/publicworks), which limits outdoor irrigation to three days per week. I am complying with the assigned schedule for my address. Any lawn stress is a direct result of following the advisory, and I respectfully request that this violation be withdrawn. I am happy to provide documentation of my compliance upon request."

Keeping your lawn alive on restricted water

Biloxi's warm, humid Gulf Coast climate supports warm-season turfgrasses. The following table summarizes how locally grown grass types handle the current 3-day irrigation schedule:

Biloxi's summer heat index regularly exceeds 100°F by July, and afternoon Gulf winds accelerate evaporation from turf and soil. To maximize the efficiency of your three allowed watering days, water deeply — aiming for 1 to 1.5 inches per session — rather than shallow and frequent. Deep watering encourages root systems to grow downward, improving resilience between sessions. Raise your mower deck to leave St. Augustine at 3.5 to 4 inches and Bermuda at 1.5 to 2 inches; taller grass shades the soil surface and reduces moisture loss significantly during Biloxi's peak summer afternoons.

Fungal disease is a real risk on the Gulf Coast, particularly for St. Augustine lawns. Gray leaf spot and brown patch thrive in Biloxi's high overnight humidity. Watering in the early morning — before 11:00 AM as the advisory requires — allows leaf blades to dry during the day, which reduces fungal pressure compared to evening irrigation. Avoid applying nitrogen-heavy fertilizer during the advisory period; lush, fast-growing turf demands more water and is more susceptible to stress when irrigation is reduced.

Biloxi water restriction FAQ

What days can I water if my Biloxi address is odd-numbered?

If your street address ends in 1, 3, 5, 7, or 9, your allowed irrigation days under the Stage 1 advisory are Monday, Wednesday, and Friday. You may water before 11:00 AM or after 4:00 PM on those days. Sunday is a no-irrigation day for all addresses. If you are unsure which category your address falls into, call Biloxi Public Works at 228-435-6270 to confirm.

Is there a fine if I water on the wrong day right now?

No. Stage 1 is a voluntary conservation advisory, and Biloxi Public Works is not issuing fines at this stage. You may receive a courtesy notice if a violation is observed, but no financial penalty applies until the utility escalates to a mandatory Stage 2 or higher restriction. That said, documented notices are tracked by the utility and could affect how quickly enforcement is applied if the stage changes.

I just installed new sod — do I have to follow the 3-day schedule immediately?

Not necessarily. Biloxi Public Works typically grants a 21-day establishment variance for newly installed sod or seeded areas, allowing more frequent irrigation during the critical root-establishment period. You must contact Biloxi Public Works before or immediately after installation to register for the variance — it is not automatic. Reach them at 228-435-6270 or biloxi.ms.us/publicworks. Once the variance period expires, your lawn reverts to the standard address-based schedule.

Can I wash my car at home in Biloxi right now?

Yes, vehicle washing is permitted under the Stage 1 advisory. Biloxi Public Works encourages using a bucket and a hose with a shut-off nozzle rather than letting water run continuously. Commercial car washes that recycle wash water are also a good option during the advisory period. There is no specific prohibition on car washing at Stage 1, but leaving a hose running unattended is broadly discouraged.

Does Biloxi Public Works use smart meters to detect irrigation violations?

Biloxi Public Works has been expanding its metering infrastructure, but Stage 1 enforcement — when it applies at higher stages — relies primarily on field patrols and complaint-based investigation rather than automated smart-meter flagging of irrigation events. If you are concerned your meter data could flag excessive use, the more practical issue is whether a neighbor or patrol officer observes runoff or midday irrigation. At Stage 2 and above, the utility has authority to investigate usage patterns; contact Public Works at 228-435-6270 for current metering details in your area.

Can I fill or top off my swimming pool during the advisory?

Yes. Pool filling and topping off are not prohibited under the Stage 1 advisory. However, Biloxi's summer heat and Gulf breezes can cause a standard residential pool to lose 1 to 2 inches of water per week to evaporation. Using a pool cover when the pool is not in use is one of the most effective ways to reduce water consumption during the advisory — far more impactful than skipping a rinse cycle on the hose.

My HOA is threatening to fine me for my lawn going brown — what do I do?

Mississippi does not have a state law specifically barring HOAs from fining residents during water restrictions, so your first step is to review your HOA's CC&Rs for any language exempting compliance with municipal utility directives. Send the HOA board a written letter (see the template in the HOA section above) citing the Biloxi Public Works Stage 1 Voluntary Conservation Advisory and documenting your compliance with the assigned watering schedule. Keep timestamped photos of your irrigation sessions. If the HOA proceeds with a fine, consult an attorney familiar with Mississippi property law and your specific association documents.

Where can I get the most current information if the restriction stage changes?

The authoritative source for Biloxi's current restriction stage, trigger thresholds, and any exemptions is Biloxi Public Works directly. Visit biloxi.ms.us/publicworks or call 228-435-6270. Stage changes can happen quickly in response to rainfall events or system demand, and the current Stage 1 advisory is scheduled to remain in effect through December 31, 2026 — but that end date can be extended or the stage can be escalated depending on conditions. Do not rely solely on third-party sites for real-time status.

What time can I water in Biloxi?
