White Plains NY Water Restrictions 2026

Current water restrictions in White Plains, New York

White Plains is under a Stage 1 Advisory with Mandatory Odd/Even restrictions, limiting outdoor watering to 2 days per week based on street address number.

The restrictions are administered by Westchester Joint Water Works (WJWW), the regional authority that supplies water to White Plains, New Rochelle, and Mount Vernon. WJWW activated its Stage 1 Advisory in response to declining reservoir levels across the Westchester system, triggering the mandatory odd/even schedule that governs when each address may irrigate.

The broader context is significant: the New York City Department of Environmental Protection (NYC DEP) declared a Drought Watch on October 15, 2025 — the first such declaration since 2002. The combined NYC reservoir system was sitting at just 67.8% of capacity against a seasonal norm of 83%, and Westchester County's interconnected supply has felt the same pressure. WJWW's Stage 1 response is directly tied to these regional conditions.

The restrictions remain in effect until conditions improve — there is no fixed end date. If May 2026 precipitation falls below 60% of normal, WJWW is expected to escalate to Stage 2, which would impose stricter limits. Residents should monitor WJWW communications for updates.

Practically speaking, what does this mean for a White Plains homeowner right now? If your street address ends in an odd number, you may water on Tuesday and Saturday. If your address ends in an even number, your allowed days are Wednesday and Sunday. On those days, irrigation must occur outside the 10 a.m.–5 p.m. window — meaning before 10 a.m. or after 5 p.m. only. A resident wanting to water their garden on a Wednesday morning would need to start before 10 a.m. and have an even-numbered address; watering on a Wednesday afternoon or on a non-assigned day is a violation under the current Stage 1 Advisory.

Watering schedule and allowed days

The odd/even assignment is determined by the last digit of your street address number — not your unit number if you're in a multi-unit building. For a house at 47 Mamaroneck Avenue, the last digit is 7 (odd), so Tuesday and Saturday are the permitted watering days. For 84 Battle Avenue, the last digit is 4 (even), making Wednesday and Sunday the allowed days.

Multi-family residential properties and commercial accounts in White Plains should use the address on file with WJWW — typically the building's primary street number. If a commercial property has multiple addresses or frontages, the account's billing address number governs. Property managers who are uncertain about their classification can contact WJWW directly to confirm which days apply to their account before a potential violation occurs.

The midday restriction — no watering from 10 a.m. to 5 p.m. — is designed to reduce evaporative loss during peak heat hours. In Westchester County's humid summer climate, early-morning watering (before 10 a.m.) is the most efficient window and also reduces foliar moisture that can linger through midday. For established trees — including the red oak, Norway maple, and American elm that are common throughout White Plains neighborhoods — deep, slow watering at the drip line during the pre-10 a.m. window on your assigned days will do far more than surface-level sprinkling. These species have extensive root systems and benefit from infrequent but deep applications rather than light daily misting.

What happens if you violate restrictions in White Plains?

WJWW's enforcement under the Stage 1 Advisory begins with a written warning for a first-time offender — no fine is assessed immediately. Repeat violations, however, carry monetary penalties that escalate with each subsequent offense. The structure is intentionally progressive: WJWW's goal at Stage 1 is compliance, not revenue, but documented repeat offenders face real financial consequences. Specific fine dollar amounts are set at the WJWW administrative level and may be confirmed by contacting the authority directly.

Enforcement relies on a combination of field patrols by WJWW staff and resident complaint reports. WJWW field representatives are active in White Plains, New Rochelle, and Mount Vernon during drought advisory periods and can issue violation notices based on direct observation. Residents can also report suspected violations to WJWW. If you receive a violation notice and believe it was issued in error — for instance, if you were using a shut-off nozzle for hand watering (which is exempt) or have a registered new-sod establishment period — you can contest the notice through WJWW's administrative process. Acting quickly after receiving a notice is important; delays can complicate an appeal.

Other outdoor water rules

Under WJWW's Stage 1 Advisory, restrictions extend beyond lawn irrigation. The following outdoor uses are either prohibited, limited, or specifically addressed:

• Car washing: Washing vehicles at home with a running hose is prohibited unless the hose has a self-closing shut-off nozzle. Commercial car washes that recycle water are permitted.
• Pool filling and top-off: Filling new pools is discouraged during the advisory; topping off existing pools to compensate for evaporation is generally permitted but should be minimized. White Plains sees significant residential pool use in summer, and evaporative loss from uncovered pools is a measurable draw on the WJWW system.
• Decorative fountains: Ornamental fountains and water features that do not recirculate water must be shut off during Stage 1.
• Pressure washing: Pressure washing of sidewalks, driveways, and building exteriors using potable water is restricted. Use of recirculating systems or grey water where available is encouraged.
• Construction water use: Contractors operating in White Plains must comply with WJWW advisory terms; dust suppression and construction site water use should be minimized and is subject to WJWW oversight.
• Restaurant and commercial exterior cleaning: Hosing down sidewalks and exterior surfaces with a free-flowing hose is not permitted; brooms or minimal water with a shut-off nozzle should be used instead.

Water source and infrastructure

White Plains receives its water through the Westchester Joint Water Works (WJWW) system, which draws primarily from the Kensico Reservoir in Valhalla, New York — the final and largest impoundment in the New York City Delaware and Catskill aqueduct system before water reaches Westchester distribution networks. Kensico is fed by the Delaware Aqueduct and the Catskill Aqueduct, both operated by NYC DEP, making White Plains's supply directly tied to the health of the broader NYC watershed system.

The NYC watershed spans approximately 1,972 square miles across Delaware, Schoharie, Ulster, Greene, Sullivan, and Putnam counties, encompassing 19 reservoirs and three controlled lakes. The major upstate impoundments feeding the system include Cannonsville Reservoir, Pepacton Reservoir, and Schoharie Reservoir — all significantly below normal levels as of the October 2025 Drought Watch declaration. Water flows south via gravity-fed aqueducts to Kensico, where it undergoes treatment and chlorination before entering the WJWW distribution system serving White Plains and surrounding municipalities.

WJWW itself operates water treatment and pumping infrastructure that draws from Kensico and delivers finished water through its tri-city network. The system does not rely on local groundwater wells or aquifers for primary supply — White Plains is almost entirely dependent on surface water sourced from the Catskill-Delaware watershed hundreds of miles to the north and west. This structural dependence means that prolonged regional drought has a direct, real-time impact on pressure and supply availability in White Plains. When NYC DEP's combined reservoir level drops below historical norms — as it has in 2025 — WJWW's supply allocation tightens proportionally, which is precisely what drove the Stage 1 Advisory.

Brown lawn protections in New York

New York State does not have a specific statute equivalent to Colorado's CRS § 37-60-126 or Florida's FS § 720.3075 that explicitly prohibits HOAs from fining homeowners for drought-related lawn browning. However, New York's Real Property Law and general HOA governance principles provide some practical leverage. During a declared drought advisory — such as WJWW's current Stage 1 — an HOA rule that effectively compels residents to violate a mandatory water restriction in order to maintain green turf could be challenged as unconscionable or contrary to public policy. Residents in HOA-governed communities in White Plains should review their governing documents and, if necessary, raise the issue formally with their HOA board in writing.

If your HOA has sent you a notice about lawn appearance during the WJWW Stage 1 Advisory, the following template response may help:

"I am writing in response to your notice dated [date] regarding lawn appearance at [address]. As you may be aware, Westchester Joint Water Works (WJWW) has implemented a mandatory Stage 1 Odd/Even Advisory restricting outdoor irrigation to two assigned days per week, with no watering permitted between 10 a.m. and 5 p.m. Compliance with this mandatory advisory limits my ability to maintain turf appearance. I am watering on my designated days in accordance with WJWW guidelines and ask that the HOA suspend any lawn appearance enforcement actions for the duration of the declared advisory. I am happy to provide documentation of the current WJWW restriction upon request."

Keep a copy of your watering log — dates, times, and duration — to document compliance with WJWW rules if the dispute escalates.

Lawn care during restrictions

White Plains sits firmly in the cool-humid Northeast climate zone, where the dominant lawn grasses are Kentucky Bluegrass, Tall Fescue, Perennial Ryegrass, and Fine Fescue. These are the grasses to plan around during WJWW's Stage 1 Advisory — not warm-season varieties.

In Westchester County's humid summer climate, fungal disease — particularly brown patch and dollar spot — is a real risk when soil stays wet overnight. Watering in the early morning on your assigned days (ideally between 5 a.m. and 9 a.m.) allows the turf surface to dry during daylight, reducing fungal pressure. Avoid the temptation to water in the evening after 5 p.m. just because it's permitted — in White Plains's humid summers, overnight wet foliage increases disease susceptibility significantly.

Raise your mower deck to at least 3.5 inches during the advisory period. Taller grass shades soil, reduces surface temperature, and cuts evaporative loss — a meaningful difference when you're limited to two watering days per week. Kentucky Bluegrass and Tall Fescue both perform best when cut high in drought stress conditions. Hold off on fertilizing with any nitrogen-heavy product until WJWW lifts the advisory; pushing growth now only increases the lawn's water demand and stress level.

Common questions about White Plains water restrictions

What days can I water if my White Plains address ends in an odd number?

If your street address ends in an odd digit (1, 3, 5, 7, or 9), your assigned watering days under WJWW's Stage 1 Advisory are Tuesday and Saturday. You must water outside the 10 a.m.–5 p.m. prohibited window — meaning before 10 a.m. or after 5 p.m. on those days only. Watering on any other day of the week is a violation of the mandatory advisory.

What happens if I water on the wrong day in White Plains?

WJWW issues a written warning for a first observed violation — no immediate fine. If you are observed violating the schedule again, monetary fines apply and escalate with subsequent offenses. WJWW field staff actively patrol service areas during advisory periods, and violations can also be reported by neighbors. A violation notice can be contested through WJWW's administrative process if you believe it was issued in error.

Is White Plains under a drought emergency, or just a watch?

White Plains is operating under a WJWW Stage 1 Advisory, which is a mandatory (not voluntary) restriction. At the state level, NYC DEP has declared a Drought Watch — the first since 2002 — as of October 15, 2025, with the combined reservoir system at 67.8% capacity. A Drought Watch is one tier below an Emergency; if conditions worsen and May 2026 precipitation falls below 60% of normal, WJWW is expected to escalate to Stage 2 with more stringent limits.

Can I fill or top off my swimming pool during the WJWW Stage 1 Advisory?

Topping off an existing pool to account for normal evaporation is generally permitted under Stage 1, though WJWW encourages minimizing this use. Filling a new pool from scratch is strongly discouraged during the advisory period. Using a pool cover reduces evaporative loss substantially — an uncovered residential pool in a Westchester summer can lose an inch or more of water per week to evaporation alone, which adds up quickly across hundreds of White Plains residential pools.

Does WJWW use smart meters to detect irrigation violations in White Plains?

WJWW has been expanding its metering infrastructure across its service territory, but the primary enforcement mechanism for irrigation violations during the Stage 1 Advisory is field observation by WJWW staff combined with resident complaints — not automated smart-meter flagging. Smart meters track total consumption rather than pinpointing the time of day water is used, so they support overall usage monitoring but are not a direct substitute for patrol-based enforcement of day/time restrictions.

Is hand watering my vegetable garden exempt from the odd/even schedule?

Yes — hand watering with a shut-off nozzle is exempt from the odd/even day restriction under WJWW's Stage 1 Advisory. You can hand-water your vegetable garden, container plants, or individual trees any day using a hose fitted with a self-closing nozzle. A free-running hose without a shut-off nozzle does not qualify for this exemption and would be subject to the standard schedule.

Can my HOA fine me for a brown lawn while WJWW restrictions are in place?

New York State does not have a statute that explicitly bars HOAs from citing homeowners for drought-related lawn browning, unlike some other states. However, enforcing an appearance standard that requires violating a mandatory government water restriction is legally questionable. Document your compliance with WJWW's schedule in writing, notify your HOA board formally that you are adhering to the mandatory advisory, and request that enforcement be suspended for the duration of the restriction. Most HOA boards in Westchester County recognize the risk of pursuing such citations during a declared advisory.

When will WJWW lift the Stage 1 Advisory for White Plains?

WJWW has not set a fixed end date. The Stage 1 Advisory remains in effect "until conditions improve" — meaning until reservoir levels across the NYC/Westchester system return to normal seasonal ranges and WJWW determines that mandatory conservation is no longer necessary. Given that the NYC DEP Drought Watch was declared in October 2025 with the combined system at 67.8% capacity, and that Stage 2 triggers are tied to spring 2026 precipitation, residents should plan their irrigation around current restrictions through at least the first half of 2026 absent significant rainfall recovery.

What time can I water in White Plains?

Watering is allowed Not 10am-5pm. Watering outside these hours is a violation even on your assigned day.

What are the fines for watering violations in White Plains?

First offense: Warning first. Repeat violations: Fines for repeat violations. Contact Westchester Joint Water Works (WJWW) for the full enforcement schedule.

When will water restrictions end in White Plains?

Current Stage 1 Advisory (Mandatory Odd/Even) restrictions are in effect through Until conditions improve. Monitor Westchester Joint Water Works (WJWW) for the latest status.
