Orange Water and Sewer Authority (OWASA), the nonprofit utility serving Chapel Hill, Carrboro and UNC Chapel Hill, states on owasa.org that Orange County is in exceptional drought but that OWASA is NOT yet in a water shortage as of July 2026, so no mandatory restrictions apply. OWASA would issue a Water Shortage Advisory if combined supply (University Lake, Cane Creek Reservoir and the Quarry Reservoir) fell to 70 per cent full, and would enter Stage 1, with a surcharge on residential use above 6,000 gallons, at 60 per cent full. This is a stronger position than neighboring Raleigh Water (Falls Lake, Stage 1 mandatory) and the Catawba-Wateree basin (Charlotte, Stage 2). OWASA monitors its supply daily on its Water Watch page and the Triangle Water Supply Partnership coordinates emergency interconnections between OWASA, Durham, Raleigh and Cary if any single system runs short.

Still Allowed

💧 Hand Watering

Allowed with shut-off nozzle. Hours: Hand watering and drip irrigation permitted any time under voluntary conservation..

🌿 Drip Irrigation

Exempt from day-of-week limits. Must follow allowed hours.

Fines & Enforcement

No mandatory fines under voluntary conservation

Voluntary conservation does not carry fines. OWASA Stage 1 Mandatory (if declared) would limit irrigation to two days per week, prohibit non-essential outdoor uses, and impose fines via the Orange County / Town of Chapel Hill ordinance framework. Stage 2 Severe and Stage 3 Emergency are deeper escalations available under the OWASA Water Shortage Response Plan if storage continues to decline.

🏠 HOA Rules During Restrictions

North Carolina HOA law (NCGS §47F-3-121 plus G.S. 143-355.2) prohibits HOAs from fining residents for dormant lawns during active mandatory drought restrictions. Under current voluntary conservation, HOA aesthetic enforcement of green lawns is not yet legally blocked but is strongly discouraged given the regional drought context.

If your homeowners association sends a violation notice for a dormant or brown lawn during the current restriction period, respond in writing citing the applicable law and include a copy of the current restriction order from Orange Water and Sewer Authority. Most HOAs will rescind the notice once they are made aware of the legal protections in place. If the issue persists, contact your county’s code enforcement division for assistance.

Why These Restrictions Exist

Chapel Hill (population ~62,000) is served by the Orange Water and Sewer Authority (OWASA), a distinct nonprofit utility (not a municipal department) that also serves Carrboro, parts of unincorporated Orange County, and the University of North Carolina at Chapel Hill campus. OWASA's primary water sources are University Lake and Cane Creek Reservoir, with the Quarry Reservoir as a drought buffer and an emergency connection to Jordan Lake via the Triangle Water Supply Partnership.

As of July 2026, OWASA reports that it is not yet in a water shortage, even though Orange County is in exceptional drought. This is a structurally stronger water position than other Triangle utilities: Raleigh Water (Falls Lake) is under mandatory Stage 1, and the Catawba-Wateree basin (Charlotte, Hickory) is at Stage 2. OWASA's smaller service area, conservation-focused community, and reservoir margin combine to delay the mandatory-restriction threshold even during the same regional drought. OWASA would issue a Water Shortage Advisory at 70 per cent combined storage and enter Stage 1 at 60 per cent.

North Carolina's drought monitor shows 100 per cent of the state in drought as of April 2026, with Orange and Durham counties in 'extreme' drought. The Triangle Water Supply Partnership (formed 2018) provides emergency interconnections between OWASA, Raleigh Water, Durham Water Management, and Cary Public Works; in a worst-case scenario, OWASA could supplement from Jordan Lake or Falls Lake via inter-utility transfers. The University of North Carolina at Chapel Hill (~30,000 students plus staff) is OWASA's largest institutional customer; summer dorm occupancy is lower than the academic year so institutional demand drops May-August.

OWASA's Water Shortage Response Plan progresses from Voluntary Conservation (current) to Stage 1 Mandatory (2 days per week irrigation, prohibitions on non-essential outdoor use), Stage 2 Severe (1 day per week or less, broader prohibitions), and Stage 3 Emergency (no outdoor watering, rationing). The trigger thresholds are based on combined storage percentage and projected days of supply. Monitor owasa.org/water-conservation for updates: if storage drops to roughly 80 per cent or projected days of supply falls below 300, OWASA typically activates Stage 1 Mandatory.

Rainfall Deficit: OWASA not in a water shortage as of July 2026 (owasa.org). Orange County in exceptional drought per NC DEQ; all 100 NC counties in drought.

This reflects the current water year for the Chapel Hill area. Water supply reservoirs and aquifer levels are below seasonal targets, prompting regional voluntary conservation guidance.

How to Keep Your Lawn Alive During Chapel Hill Water Restrictions

10 tips tailored for Chapel Hill homeowners during No mandatory restrictions - OWASA conservation (not in a water shortage) restrictions.

OWASA is on voluntary conservation, distinct from Falls Lake (Raleigh) mandatory Stage 1 and Catawba-Wateree (Charlotte) Stage 2 LIP. Verify your utility on your bill before applying any specific framework.

Reduce outdoor irrigation by 20-30 per cent now to pre-empt a possible mandatory Stage 1 escalation; OWASA's 511-day supply margin is structural but not infinite.

Tall Fescue (dominant Chapel Hill lawn grass) handles dormancy for 4-6 weeks during summer drought. Allow browning rather than overwatering.

Hand watering with a shut-off nozzle is permitted any time. Prioritise mature trees, food crops, and high-value shrubs over ornamental beds.

Carrboro is on the same OWASA system: same voluntary conservation, same rules, same supply.

Install a rain barrel: captured rainwater is unrestricted at every OWASA stage and is the most reliable buffer if Stage 1 takes effect later in 2026.

Mow at 75-100 mm and leave clippings on the lawn to shade soil and slow evaporation.

Skip nitrogen fertiliser through summer. It forces growth that demands water the lawn cannot receive under future Stage 1 prohibitions.

UNC summer break (mid-May to late August) drops campus water demand by 60-70 per cent versus the academic year, which gives OWASA additional summer-season margin.

Monitor owasa.org/water-conservation weekly. If storage drops below 80 per cent or projected days of supply below 300, OWASA typically activates Stage 1 Mandatory.

Chapel Hill Water Restriction FAQs

What days can I water my lawn in Chapel Hill?
Under No mandatory restrictions - OWASA conservation (not in a water shortage), Chapel Hill does not have an assigned-day schedule. You may water any day of the week, though the utility encourages voluntary reduction to reduce outdoor use during drought conditions.
What hours can I run my sprinklers in Chapel Hill?
Under voluntary conservation, Chapel Hill has no mandatory hour restrictions. The utility recommends watering in the early morning or evening to reduce evaporation, but no citations apply under voluntary conservation.
What are the fines for water violations in Chapel Hill?
Voluntary conservation does not carry fines. OWASA Stage 1 Mandatory (if declared) would limit irrigation to two days per week, prohibit non-essential outdoor uses, and impose fines via the Orange County / Town of Chapel Hill ordinance framework. Stage 2 Severe and Stage 3 Emergency are deeper escalations available under the OWASA Water Shortage Response Plan if storage continues to decline. The Orange Water and Sewer Authority (OWASA) and local Orange (most of Chapel Hill) + small slice of Durham enforcement officers conduct patrols and respond to complaints. Keep your irrigation timer set to your assigned day and hours to avoid citations.
Can I install new sod or seed in Chapel Hill during restrictions?
No mandatory new-lawn restrictions under current voluntary conservation. OWASA recommends delaying new sod or seed installations until autumn given regional NC drought.
When will water restrictions end in Chapel Hill?
The current No mandatory restrictions - OWASA conservation (not in a water shortage) conservation guidance in Chapel Hill is effective from Conservation encouraged; no mandatory water shortage declared Until University Lake + Cane Creek + Quarry storage declines to the shortage triggers. However, the guidance may be extended if drought conditions persist or eased if significant rainfall improves water supply levels. Monitor the Orange Water and Sewer Authority (OWASA) website for updates.
Is this Chapel Hill, NC, or Chapel Hill, TN?
This page is Chapel Hill, North Carolina (Orange County, ~62,000 residents, home to UNC Chapel Hill, served by Orange Water and Sewer Authority / OWASA). Chapel Hill, Tennessee (Marshall County, ~1,500 residents) is a small town south of Nashville with its own municipal water under separate Tennessee state framework. The OWASA voluntary conservation described here applies only to Chapel Hill, NC and Carrboro, NC customers on the OWASA system.
Carrboro vs Chapel Hill - different rules?
No. Carrboro and Chapel Hill are both served by Orange Water and Sewer Authority (OWASA) and follow identical water conservation rules. The two towns are sometimes called 'twin cities' on the OWASA system. Whether you live in Chapel Hill, Carrboro, the UNC campus area, or unincorporated Orange County served by OWASA, the same voluntary conservation (currently) or future Stage 1 mandatory rules apply.
Why is OWASA different from Falls Lake (Raleigh) restrictions?
OWASA, Raleigh Water, Durham Water Management, and Cary Public Works each operate distinct utilities with separate reservoirs and supply positions. OWASA draws from University Lake + Cane Creek + Quarry (combined ~90 per cent in April 2026, 511 days of supply). Raleigh Water draws from Falls Lake Reservoir (84 per cent in April 2026, triggered mandatory Stage 1). Durham draws from Lake Michie + Little River Reservoir. Cary draws from Jordan Lake (better-buffered). The Triangle Water Supply Partnership (formed 2018) provides emergency interconnections, but each utility sets its own stage independently. Crossing the county line into Wake County (Raleigh) means a different utility and different rules.
I commute to Raleigh - do I need to know both stages?
Yes, if you operate water-using equipment in both. Your home address determines your residential rules: if you live in OWASA service area, you follow OWASA voluntary conservation regardless of where you work. If your workplace is in Raleigh and uses water for irrigation, vehicle washing, or pool maintenance, those activities follow Raleigh Water Stage 1 Mandatory rules at the workplace site. The two utilities operate independently and rules apply per-property, not per-person.
UNC dorms during summer break - does student volume affect supply?
Summer dorm occupancy is significantly lower than the September-April academic year, so UNC institutional water demand drops 60-70 per cent from late May through late August. This is a meaningful seasonal margin for OWASA because UNC is the largest single institutional customer in the service area. Off-campus student rentals in Chapel Hill and Carrboro contribute to summer residential demand the same way as other households.
