Chapel Hill Water Restrictions 2026

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 April 2026, OWASA reported its combined storage at roughly 90 per cent of capacity, providing about 511 days of supply at current demand without significant rainfall. This is a structurally stronger water position than other Triangle utilities: Falls Lake (Raleigh) hit mandatory Stage 1 in April 2026 at 84 per cent of capacity, and the Catawba-Wateree basin (Charlotte / Hickory) is at Stage 2 LIP Mandatory in effect since May 15, 2026. OWASA's smaller service area, conservation-focused community, and reservoir margin combine to delay the mandatory-restriction threshold even during the same regional drought.

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.

This deficit has accumulated over the current water year and represents a significant departure from historical averages for the Chapel Hill area. Water supply reservoirs and aquifer levels are below seasonal targets, prompting regional voluntary conservation guidance.
