# Anaheim Groundwater Well Failure Triggers Citywide Water-Pressure Collapse > Several Anaheim municipal groundwater wells failed around 6 p.m. on July 28, 2026, collapsing citywide water pressure and briefly closing Disneyland restrooms and restaurants to entry. Pressure was restored the same night with no boil-water advisory; affected wells remained offline pending investigation. The acute pressure emergency is resolved. - Canonical: https://ocint.app/situation/anaheim-water-pressure-well-failure-2026-07 - Markdown: https://ocint.app/situation/anaheim-water-pressure-well-failure-2026-07.md - JSON: https://ocint.app/api/situations/anaheim-water-pressure-well-failure-2026-07 - Status: archived - As of: 2026-08-17T03:02:25.457+00:00 - Started: 2026-07-29T01:00:00+00:00 - Cities: Anaheim - Publisher: OCINT (https://ocint.app) ## Who / What / Where / When / Why **Who:** City of Anaheim (Anaheim Public Utilities operates the municipal water system). Affected parties included the Disneyland Resort, Angel Stadium of Anaheim, and hotels, restaurants, and residents across central Anaheim and surrounding neighborhoods. **What:** A sudden loss of municipal water pressure across much of Anaheim after several of the city's groundwater wells went offline. According to reporting by KTLA and CBS Los Angeles, the drop left many locations with little or no water pressure; at the Disneyland Resort all restrooms and restaurants were closed to entry during the disruption. Per Tech Times, four of Anaheim's 14 groundwater wells failed at roughly the same time. City staff said there were no water-quality concerns and no boil-water advisory was issued. **Where:** Citywide across Anaheim, Orange County, with the most visible effects in the Anaheim Resort District (Disneyland) and at Angel Stadium. The impact area is drawn to the City of Anaheim boundary, which approximates the Anaheim Public Utilities water service footprint. **When:** The pressure problem was reported around 6 p.m. PT on Tuesday, July 28, 2026. According to CBS Los Angeles and KTLA, service at the Disneyland Resort was restored by roughly 8 p.m., and citywide pressure was reported restored later that night. The affected wells remained offline pending investigation into why they failed simultaneously. **Why:** The cause of the simultaneous well failures had not been determined as of the reporting. City crews said they were still working to identify what caused the pump/well problem, and the affected wells were kept offline pending investigation. As a contingency, Anaheim increased its draw of imported Colorado River water to supplement supply while local groundwater production was down. ## Narrative ## Anaheim citywide water-pressure collapse (July 28, 2026) Around 6 p.m. PT on Tuesday, **July 28, 2026**, much of Anaheim lost municipal water pressure after several of the city's groundwater wells went offline. According to KTLA and CBS Los Angeles, the drop affected the **Disneyland Resort**, **Angel Stadium of Anaheim**, hotels, restaurants, and residential neighborhoods across the city. At Disneyland, **all restrooms and restaurants were closed to entry** during the disruption. ### Scope - Reporting by Tech Times states that **four of Anaheim's 14 groundwater wells failed at roughly the same time**, triggering the pressure loss. - City staff said there were **no water-quality concerns** and that **no boil-water advisory** was issued. - As a contingency, Anaheim increased its draw of **imported Colorado River water** to supplement supply while local groundwater production was down. ### Timeline - **~6 p.m. PT, Jul 28** — Pressure problems reported citywide; Disneyland closes restrooms/restaurants to entry. - **~8 p.m. PT** — Disneyland Resort water service reported restored (CBS Los Angeles, KTLA). - **Later that night** — Citywide pressure reported restored. - **Ongoing** — Affected wells kept offline pending investigation into the simultaneous failure; cause not yet disclosed. ### Why it matters Anaheim is home to Orange County's largest tourism and events economy. A simultaneous multi-well failure that idled a meaningful share of the city's groundwater capacity — with no immediately disclosed cause — raises questions about water-system reliability and redundancy that outlast the same-night restoration. This page tracks the follow-up: the investigation findings, whether the wells return to service, and any regulatory or infrastructure response. *Sources: KTLA, CBS Los Angeles, Tech Times (see factoids for links).
