Albuquerque NM Water Restrictions 2026

Current water restrictions in Albuquerque, New Mexico

Albuquerque is under Seasonal Mandatory restrictions, limiting outdoor watering to 2 days per week on assigned days during specific hours. The Albuquerque Bernalillo County Water Utility Authority (ABCWUA) administers and enforces these restrictions as part of its annual outdoor watering program, which applies to all residential, commercial, and institutional accounts within its service area.

The restrictions reflect Albuquerque's structural dependence on the Rio Grande, which supplies the city through the San Juan-Chama Drinking Water Project — a system that diverts water from the Colorado River Basin across the Continental Divide into the Rio Grande watershed. Deliveries under that project are managed through federal contracts and are sensitive to upstream storage levels in Heron Lake Reservoir and El Vado Reservoir. When allocations tighten, mandatory conservation measures at the municipal level follow directly.

New Mexico is experiencing drought conditions statewide, adding pressure to an already over-allocated river system. The state has historically relied on both Rio Grande surface flows and the Santa Fe Group aquifer system; Albuquerque's own Drinking Water Production Facilities draw from both the river and local groundwater to maintain supply. Reduced snowpack in the San Juan Mountains, which feeds the Colorado River tributaries used by the project, has contributed to lower carryover storage in recent years.

Practically speaking, a resident cannot water their lawn on a Wednesday morning unless Wednesday falls on one of their two assigned watering days. Even then, watering must be completed before 10 a.m. or begin no earlier than 7 p.m. Midday watering — which the ABCWUA estimates wastes up to 30 percent of applied water through evaporation — is prohibited regardless of the day. A homeowner who wants to hand-water a vegetable garden on an off day may do so, provided they use a hose with a shut-off nozzle, as hand watering is exempt from the day restrictions.

When can you water in Albuquerque?

Rule	Details
Days per week	2
Day assignment	2 assigned days/week (seasonal)
Allowed hours	Before 10 a.m. or after 7 p.m.
Hand watering	Exempt — shut-off nozzle required on all hoses
Drip irrigation	Exempt from day restrictions; still subject to time-of-day guidance
New sod/seed	Usually a 30-day establishment window — register with Albuquerque Bernalillo County Water Utility Authority

The ABCWUA assigns watering days based on the last digit of the service address or account number. Odd-numbered addresses typically water on one pair of days; even-numbered addresses on another. The authority publishes the exact odd/even calendar on its website each spring when the seasonal program activates, so residents should confirm their specific assigned days at abcwua.org rather than guessing from prior years, as the calendar can shift.

Multi-family residential properties — apartment complexes, condominiums, and mobile home parks — are treated as single accounts and must follow the same two-day limit that applies to the master meter address. Commercial landscape irrigation accounts operate under identical day and time-of-day restrictions. Properties with large common-area turf, such as golf courses and city parks managed under ABCWUA service, may be subject to separate negotiated water budgets in addition to the day-count restrictions.

Newly planted areas do receive a temporary watering allowance beyond the standard two days. The ABCWUA requires registration for the establishment-period exemption, and it typically covers sod, seeded areas, and newly installed trees and shrubs for up to 30 days after installation. In Albuquerque's high-desert climate, large canopy trees like Rio Grande Cottonwood (Populus deltoides wislizeni), New Mexico Olive (Forestiera neomexicana), and Desert Willow (Chilopsis linearis) are drought-adapted once established but benefit from deep, infrequent irrigation during their first two to three growing seasons — a practice compatible with drip-line exemptions even during mandatory restrictions.

Penalty schedule for water violations

Offense	Penalty
First	Warning — written or door-hanger notice, no monetary fine
Second	Monetary fine assessed to utility account
Repeat/ongoing	Escalating fines; potential flow restrictor installation on service line

The ABCWUA uses a combination of customer complaint reports, field staff patrols, and its Advanced Metering Infrastructure (AMI) smart meter network to detect violations. Smart meters transmit usage data at short intervals, making it possible for utility analysts to flag accounts with high irrigation consumption during prohibited hours or on non-assigned days. Complaint reports from neighbors can also trigger a field inspection, typically within a few business days of the report being filed.

Customers who believe a violation notice was issued in error have the right to contest the finding through the ABCWUA's customer service process. An appeal should be submitted in writing to the authority's Conservation Division, citing the account number and the specific circumstance — for example, an automatic irrigation controller malfunction or a meter read attributed to the wrong address. The ABCWUA has historically shown flexibility for first-time procedural errors but expects documented corrective action before waiving fines on subsequent appeals.

Other outdoor water rules

Outdoor water restrictions in Albuquerque extend beyond lawn irrigation. The following activities are regulated or restricted under the seasonal mandatory program:

• Vehicle washing at home: Permitted only with a hose equipped with a positive shut-off nozzle. Allowing water to run unattended from a hose is prohibited. Commercial car washes that recirculate water are exempt.
• Swimming pool filling and topping off: Initial fills for new pools require a variance from the ABCWUA. Routine topping off to replace evaporation loss is generally permitted but should use a float valve — letting a pool overflow while filling is a citable waste event. Pool covers are strongly recommended to reduce evaporation, which is significant in Albuquerque's low-humidity, high-altitude environment.
• Fountains and decorative water features: Ornamental fountains that do not recirculate water are prohibited. Recirculating fountains are allowed but must not be allowed to leak or overflow.
• Pressure washing: Pressure washing of driveways, sidewalks, and structures solely for cosmetic cleaning is discouraged and may be restricted during elevated shortage stages. Using potable water to wash down a driveway is explicitly identified by the ABCWUA as wasteful use.
• Construction water use: Commercial and residential construction sites must comply with dust suppression and grading water use requirements managed through separate permit conditions; routine site watering must minimize runoff onto adjacent streets and storm drains.
• Restaurant table water: Albuquerque maintains a water-on-request policy for restaurant table service during active drought periods, aligned with state guidance from the New Mexico Office of the State Engineer.

Where Albuquerque's water comes from

Albuquerque's municipal water supply comes from two primary sources managed jointly by the ABCWUA: Rio Grande surface water delivered via the San Juan-Chama Drinking Water Project, and groundwater drawn from the Middle Rio Grande Basin aquifer system — specifically the Santa Fe Group aquifer, which underlies the Albuquerque Basin and has historically been the city's backup and blending supply.

The San Juan-Chama Project diverts water originating in the Piedra, Blanco, and Little Navajo rivers — tributaries of the San Juan River within the Colorado River Basin — through tunnels under the Continental Divide and into Heron Lake Reservoir near Tierra Amarilla, New Mexico. From Heron Lake, water flows into El Vado Reservoir on the Chama River, then downstream into the Rio Grande. The ABCWUA holds a contract entitlement of approximately 48,200 acre-feet per year under this project, though actual deliveries depend on Colorado River compact allocations and upstream storage conditions.

Surface water from the Rio Grande is treated at the Paseo del Norte Water Treatment Plant, Albuquerque's primary surface water treatment facility, which came online in 2014 and has a design capacity of 40 million gallons per day. The plant uses ultrafiltration membrane technology and is one of the largest inland desalination-style membrane plants in the Southwest. Treated water is distributed through a network that connects to the city's groundwater production wells, which draw from the Santa Fe Group aquifer via wellfields distributed across the metro area.

The aquifer is no longer the primary source — the city shifted its strategy after studies in the late 1990s confirmed the aquifer was being drawn down faster than it could recharge. The current blended-supply approach uses river water to reduce aquifer withdrawals, allowing long-term recharge of the groundwater system. During drought years when Rio Grande flows and San Juan-Chama deliveries are reduced, ABCWUA must increase aquifer withdrawals and impose stricter demand-side restrictions — which is precisely the mechanism that drives the seasonal mandatory program.

Can your HOA fine you for a brown lawn?

New Mexico does not have a specific statute equivalent to Colorado's CRS § 37-60-126 or Nevada's NRS § 116.31075 that explicitly prohibits homeowners associations from fining members for brown lawns during a government-mandated water restriction. However, New Mexico's HOA governance is addressed under the New Mexico Homeowner Association Act (NMSA 1978, Chapter 47, Article 16) for planned communities, which allows governing documents to be challenged when enforcement is unreasonable or contrary to law or public policy.

During an active mandatory restriction declared by the ABCWUA — a government authority — enforcing a fine against a homeowner for failing to maintain a green lawn would likely be characterized as unreasonable and contrary to public policy. Homeowners in this situation should document their compliance with the ABCWUA's two-day watering schedule and communicate that compliance in writing to their HOA board before any fine hearing.

Use this template as a starting point for your written response to an HOA notice:

"I am writing to contest the lawn appearance notice dated [DATE]. Albuquerque is currently under Seasonal Mandatory outdoor watering restrictions administered by the Albuquerque Bernalillo County Water Utility Authority (ABCWUA). Under the active restriction, outdoor irrigation is limited to two assigned days per week. My lawn's current condition is a direct result of compliance with these mandatory government-imposed limits, not neglect. Enforcing an aesthetic fine under these conditions conflicts with public policy and the lawful authority of the ABCWUA. I request that this notice be withdrawn and that no fine be assessed for the duration of the mandatory restriction period."

If the HOA declines to withdraw the fine, contact the ABCWUA Conservation Division at abcwua.org to request a letter confirming the active restriction status, which can be submitted as supporting documentation in an HOA dispute or small claims proceeding.

How to manage your lawn during drought

Grass Type	Drought Tolerance	Survives 2-Day Watering?	Notes
Bermudagrass	High	Yes — goes dormant, recovers	Most common turf in Albuquerque; deep roots tolerate heat and dry spells well
Buffalograss	Very High	Yes — minimal input needed	Native to the Southern Plains; thrives in Albuquerque's alkaline soils with almost no supplemental water once established
Blue Grama	Very High	Yes — lowest water requirement of any turf option	Native grass; New Mexico's state grass; widely used in water-wise Albuquerque landscapes
Tall Fescue	Moderate	Marginal — will stress and thin	Requires more water than Bermuda or native grasses; not recommended for new installations during restrictions

Albuquerque's high-desert climate — roughly 9 to 10 inches of annual precipitation, intense UV radiation at 5,300 feet elevation, and very low relative humidity — accelerates soil moisture loss even when air temperatures are moderate. During active restrictions, raise mowing height for Bermudagrass to 2–2.5 inches rather than the typical 1.5-inch summer cut; taller blades shade soil, reduce surface temperature, and extend the period between effective irrigations. Apply water during the early-morning window (before 10 a.m.) rather than the evening window when possible — Albuquerque's low overnight humidity means evening watering still dries quickly, reducing fungal risk, but early morning reduces drift loss from the afternoon wind that develops along the Rio Grande valley most summer days.

The ABCWUA's Water Wise program actively promotes conversion of high-water turf — particularly large Tall Fescue or hybrid Bermuda lawns — to xeriscape designs using Blue Grama, Buffalograss, drip-irrigated native perennials, and decomposed granite mulch. Residents replacing existing turf are eligible for rebates through the authority's turf replacement program, which reduces long-term irrigation demand by an estimated 50–70 percent compared to traditional lawn areas. Existing Bermudagrass and native grass lawns that go partially dormant and brown during the restriction period will recover in fall when temperatures drop and the ABCWUA typically extends permitted watering days briefly before the winter shutdown.

Questions residents are asking

What two days can I water at my Albuquerque address?

Your assigned watering days are determined by the ABCWUA based on your service address or account number — typically odd vs. even address assignments. The authority publishes its current seasonal watering day calendar at abcwua.org each spring. Log in to your account or look up your address on the conservation page to confirm your exact pair of days, as assignments can vary by zone and are updated annually.

What hours am I allowed to run my sprinklers in Albuquerque?

Sprinkler and irrigation systems may run before 10 a.m. or after 7 p.m. on your assigned watering days. Irrigation between 10 a.m. and 7 p.m. is prohibited under the Seasonal Mandatory restrictions regardless of which days are assigned. If your automatic controller is currently set for a midday cycle, reprogram it immediately — a violation detected during prohibited hours still results in a warning or fine even if the day itself is permitted.

Does the ABCWUA use smart meters to detect watering violations?

Yes. The ABCWUA has deployed Advanced Metering Infrastructure (AMI) across its service area, which transmits water usage data at frequent intervals. Utility analysts can identify accounts running high irrigation volumes during prohibited hours or on non-assigned days by reviewing meter-read patterns. You do not need a neighbor complaint for a violation to be detected — anomalous usage data alone can trigger a field inspection.

Can I water my vegetable garden on days I'm not assigned to irrigate?

Yes, if you hand-water using a hose with a positive shut-off nozzle. Hand watering with a shut-off nozzle is exempt from the two-day-per-week day restriction under the ABCWUA's seasonal program. Drip irrigation systems connected to vegetable beds are similarly exempt from the day restriction, though the ABCWUA encourages running drip during early morning hours to minimize evaporation loss.

What rebates does the ABCWUA offer for replacing my lawn?

The ABCWUA's Water Wise Landscaping Rebate program offers per-square-foot rebates for removing traditional turf and replacing it with water-efficient landscaping — typically native plants, drip irrigation, and gravel or mulch ground cover. Rebate amounts and program caps are updated seasonally; visit abcwua.org and navigate to the Conservation Rebates section for the current rate and application. Projects must be pre-approved before removal begins to qualify.

Can I fill my swimming pool during the Seasonal Mandatory restrictions?

Topping off an existing pool to replace evaporation is generally permitted, but initial fills for new pools require a variance from the ABCWUA. Let an automatic float valve manage top-off rather than running a hose unattended, since unattended hose flow is classified as waste and is citable. In Albuquerque's dry climate, a pool without a cover can lose several inches of water per week to evaporation — a pool cover is the single most effective conservation measure for pool owners during restrictions.

Is Albuquerque's water system at risk of mandatory cuts beyond the seasonal program?

Yes — if Rio Grande surface flows fall significantly below contracted delivery levels or if the New Mexico Office of the State Engineer curtails ABCWUA's San Juan-Chama Project entitlements, the authority has authority to escalate to stricter shortage stages. ABCWUA's Water Conservation Plan outlines a staged shortage response that can reduce outdoor irrigation to one day per week or implement a mandatory percentage reduction in overall usage. The trigger thresholds are tied to Heron Lake Reservoir storage levels and real-time Rio Grande gauge data.

My HOA says my lawn looks dead. Can they fine me while restrictions are in force?

Enforcing an HOA aesthetic fine for a brown or dormant lawn that is the direct result of complying with ABCWUA's Seasonal Mandatory restrictions is legally and ethically questionable under New Mexico HOA law, even without a specific protective statute. Document your watering schedule compliance, request a written confirmation of the active restriction from the ABCWUA Conservation Division, and submit it to your HOA board in writing before any fine hearing. See the HOA section above for a template response letter tailored to this restriction phase.

What days can I water my lawn in Albuquerque?

2 assigned days/week (seasonal) Hand watering with a shut-off nozzle is typically allowed any day during permitted hours.

What time can I water in Albuquerque?

Watering is allowed Before 10am or after 7pm. Watering outside these hours is a violation even on your assigned day.

When will water restrictions end in Albuquerque?

Current Seasonal Mandatory restrictions are in effect through Seasonal. Monitor https://www.abcwua.org for the latest status.
