Rock Hill SC Water Restrictions 2026

Current water restrictions in Rock Hill, South Carolina

Rock Hill is under Mandatory Stage 2 Catawba-Wateree Low Inflow Protocol restrictions effective May 1, 2026. The city is the largest South Carolina member of the Catawba-Wateree Water Management Group, and Deputy City Manager Jimmy Bagley chairs the regional Drought Management Advisory Group that publicly announced the Stage 2 declaration. This is the first Stage 2 declaration since 2009 across the entire Catawba-Wateree basin.

Rock Hill is the first South Carolina city to enter mandatory Catawba-basin restrictions in this drought cycle, and the only SC city in our database currently at Stage 2. The city draws water directly from the Catawba River through its own intake and treatment facility — distinct from the Lake Norman / Mountain Island Lake intakes that supply Charlotte and the North Carolina Catawba towns. As a downstream user, Rock Hill is particularly attentive to the cumulative effects of upstream withdrawals during drought.

The city's location in York County, South Carolina places it at the heart of the rapidly growing Charlotte metro region. Rock Hill has more than 77,000 residents and is part of the Charlotte-Gastonia-Concord MSA. Like its NC neighbors, Rock Hill has seen significant population growth over the past decade, putting steady pressure on water infrastructure during drought conditions.

The restrictions apply to every customer of Rock Hill Utilities — residential, commercial, institutional. Private well owners are exempt; voluntary conservation is still encouraged for them. Winthrop University, the Comporium business district, and the city's industrial customers are all subject to the same Stage 2 schedule, with custom conservation plans for the largest institutional users.

Stage 2 is the second of four tiers in the Catawba-Wateree Drought Management Plan. Stage 3 would prohibit virtually all outdoor irrigation across the entire basin and is reserved for further reservoir declines. The Water Management Group reassesses monthly.

Watering schedule and allowed days

Rock Hill follows the basin-wide Catawba-Wateree Stage 2 schedule — two days per week, by address, with watering allowed only between 6 p.m. and 6 a.m.

The 12-hour daytime ban is the most consequential element of the schedule. Watering between 6 a.m. and 6 p.m. is a Stage 2 violation regardless of which day it is.

• Hand watering with a shut-off nozzle for new plantings, vegetable gardens, and trees: permitted any day.
• Drip irrigation and soaker hoses: permitted any day; not subject to the twice-weekly limit.
• Newly installed sod or seed within 30 days: contact Rock Hill Utilities at 803-329-5500 for a temporary variance.
• Rain barrels and HVAC condensate water: not regulated.
• Athletic fields, parks, golf courses: reduced schedules per Public Works coordination.

What happens if you violate restrictions in Rock Hill?

Rock Hill's enforcement framework starts with a written warning and escalates through fines per the city ordinance.

• First violation: a written warning, with the violation logged.
• Second and subsequent violations: fines per the city ordinance, added to the customer's water bill.
• Persistent violations: potential service termination until reconnect fees are paid.

Enforcement is administered by Rock Hill Utilities with field inspections and complaint-driven follow-up. To report a violation, call 803-329-5500 or submit a request through the city website at cityofrockhill.com. Reports do not require the reporter's identity.

Appeals can be submitted in writing to Rock Hill Utilities within 14 days of the violation notice, with documentation supporting the appeal.

Other outdoor water rules

Stage 2 in Rock Hill covers more than lawn watering:

• Vehicle washing at home: prohibited. Use a commercial car wash that recycles water.
• Power washing of driveways, walkways, decks, and exteriors: prohibited except for legitimate health-and-safety needs.
• Pool top-offs: permitted only Thursday and Sunday between 6 p.m. and 6 a.m. New pool fills are prohibited.
• Decorative fountains without aquatic life: must be turned off. Fountains supporting fish or aquatic plants are exempt.
• Construction water (dust suppression, masonry, concrete): contractors should obtain a written variance from Rock Hill Utilities.
• Winthrop University, the Manchester Meadows soccer complex, and other large institutional users: subject to custom conservation plans negotiated with the city, balancing operational needs with the basin-wide reduction goal.
• Commercial nurseries: exempt for inventory watering.

Water source and infrastructure

Rock Hill's drinking water comes directly from the Catawba River. The city operates its own raw-water intake and treatment plant, drawing water from the river and treating it on-site for distribution. This is a different model from the upstream Catawba towns, which mostly draw from impounded reservoirs (Lake Norman, Mountain Island Lake).

The Catawba River begins high in the Blue Ridge Mountains of western North Carolina and flows roughly 220 miles southeast through a string of eleven Duke Energy reservoirs before reaching Rock Hill. The reservoirs in order are Lake James, Rhodhiss, Hickory, Lookout Shoals, Norman, Mountain Island, Wylie, Fishing Creek, Great Falls, Cedar Creek, and Wateree. Rock Hill's intake sits between Lake Wylie (just upstream) and Fishing Creek Reservoir.

Because Rock Hill is on the river itself rather than a reservoir, the city's raw-water availability is a function of both upstream reservoir releases and the Catawba's natural flow. During Stage 2, Duke Energy adjusts releases from the upstream reservoirs to balance hydropower generation, downstream water-supply needs, and ecological flow targets, and the basin-wide Drought Management Plan governs all of these tradeoffs simultaneously.

Deputy City Manager Jimmy Bagley's role chairing the Catawba-Wateree Drought Management Advisory Group reflects Rock Hill's particularly strong stake in the basin-wide decisions. As a downstream user with direct river withdrawal, the city is sensitive to cumulative withdrawal volumes from upstream cities — and as the largest South Carolina member of the management group, it represents the SC perspective in basin-wide deliberations.

For real-time reservoir conditions, Duke Energy publishes daily storage data at duke-energy.com. As of the May 2026 Stage 2 declaration, reservoir storage across the chain was running multiple feet below normal pool elevations and inflows from upstream were tracking the lowest values since 2008.

Brown lawn protections in South Carolina

South Carolina has a different HOA-protection framework from North Carolina, but the practical protection for homeowners is similar during a mandatory drought response.

Under SC Code § 27-30-145 (and related provisions of the South Carolina Homeowners Association Act), homeowners are entitled to install drought-tolerant landscaping that does not violate aesthetic standards in the governing documents, and HOAs cannot impose enforcement actions that would force a homeowner to violate a state, regional, or local mandatory water restriction. The Catawba-Wateree Stage 2 declaration is exactly that kind of mandatory restriction.

Sample HOA response letter for Rock Hill homeowners:

"Dear [HOA Board], the City of Rock Hill is enforcing Stage 2 Catawba-Wateree Low Inflow Protocol restrictions effective May 1, 2026. Outdoor irrigation is limited to two overnight windows per week and I am in compliance. Under SC Code § 27-30-145 and the South Carolina Homeowners Association Act, my compliance with this mandatory restriction takes precedence over any landscape covenant in our governing documents. Please withdraw the violation. The Catawba-Wateree Water Management Group's stage status is published at catawbawateree.org. Sincerely, [Your name]"

Keep records of correspondence. The South Carolina Department of Consumer Affairs maintains an HOA assistance program that can help mediate disputes when documented mandatory restrictions are in effect.

Lawn care during restrictions

Rock Hill is in the upper transition zone, the same climate band as the rest of the Charlotte metro. Tall fescue dominates residential lawns, with bermudagrass on hot, south-facing sites and a smaller share of zoysiagrass and Kentucky bluegrass.

Mow high. Set fescue to 4 inches. Taller blades shade the soil and protect crowns.

Leave clippings. Mulched clippings return moisture and nitrogen and reduce the lawn's water demand.

Hold fertilizer and aeration. Both push growth and create evaporative pathways.

Brown is not dead. Tall fescue dormancy is a survival mechanism. Crowns recover when temperatures drop and rainfall returns; September overseeding fills any thin spots.

Common questions about Rock Hill water restrictions

What days can I water my lawn in Rock Hill?

Two days per week, by address: odd addresses water Tuesday and Saturday; even addresses water Wednesday and Sunday. Watering is permitted only between 6 p.m. and 6 a.m. on the assigned days.

What time can I water in Rock Hill?

6 p.m. to 6 a.m. on your two assigned days. Daytime watering between 6 a.m. and 6 p.m. is a Stage 2 violation regardless of the day.

What are the fines for watering violations in Rock Hill?

First violation: a written warning. Subsequent violations: fines per the city ordinance, added to your water bill. Persistent violations can result in service termination.

Why did Rock Hill go to Stage 2 before any other SC city?

Rock Hill is the largest South Carolina member of the Catawba-Wateree Water Management Group, which manages the entire basin's drought response across both states. Stage 2 was declared basin-wide on May 1, 2026 by the management group, and Rock Hill — with direct withdrawal from the Catawba River — implemented the schedule immediately. Other SC cities are not on the Catawba system and operate under separate frameworks.

I'm on a private well — do restrictions apply to me?

No. Stage 2 applies only to customers of Rock Hill Utilities. Well users are exempt because they draw groundwater rather than the Catawba surface-water supply.

Will Rock Hill move to Stage 3?

It is possible if reservoir storage continues to decline. Stage 3 would prohibit virtually all outdoor irrigation and apply across the entire Catawba basin simultaneously. The Water Management Group reassesses monthly.

How does Rock Hill's water-supply situation compare to Charlotte's?

Rock Hill draws directly from the Catawba River, while Charlotte draws from impounded reservoirs upstream (Lake Norman, Mountain Island Lake). Both rely on the same basin-wide drought management framework, but Rock Hill's supply is more directly affected by river-flow conditions and upstream releases. The Stage 2 schedule is identical for both cities.

How do I report a water waste violation in Rock Hill?

Call Rock Hill Utilities at 803-329-5500 or use the online reporting form at cityofrockhill.com.

When will water restrictions end in Rock Hill?

Current Mandatory Stage 2 — Catawba Basin LIP restrictions are in effect through Until Catawba Basin conditions improve. Monitor https://www.cityofrockhill.com for the latest status.

Can I hand water during Rock Hill water restrictions?

Yes. Hand watering with a hose fitted with a shut-off nozzle is generally allowed on any day during permitted hours. Drip irrigation and soaker hoses are also typically exempt from the day-of-week schedule. Confirm specifics with City of Rock Hill Utilities.
