Granada Hills & Porter Ranch: Water Outage, Boil Notice, and How to Get Help
Urgent Water Outage and Boil Water Notice Impact Granada Hills and Porter Ranch, Los Angeles

Residents in the Granada Hills and Porter Ranch neighborhoods of Los Angeles County are currently facing a significant water outage accompanied by a critical boil water notice. This unexpected disruption to essential water services stems from a recent valve failure during emergency repairs at a local pump station. The Los Angeles Department of Water and Power (LADWP) is responding swiftly, prioritizing support for all affected communities. This comprehensive guide details the reasons behind the water outage in Granada Hills, highlights the specific areas impacted, outlines LADWP's dedicated response, and provides crucial boil water safety guidelines for all residents.
Cause of the Water Service Interruption

The water service interruption in Granada Hills and Porter Ranch was triggered by a critical valve failure. This occurred during ongoing repairs at a pump station that supplies water to the affected areas. Specifically, the valve failed to open, which prevented the necessary refilling of a 10-million-gallon water tank – a key component in providing water to these neighborhoods. The complexity of the repair is heightened by the valve’s location, approximately 20 feet underground, necessitating extensive excavation. Further complicating efforts are nearby critical infrastructure, including oil pipelines, a fiber optic line, and a gas line, alongside large boulders obstructing access.
Areas Impacted by the Water Outage

The water outage in Los Angeles primarily affects areas within Granada Hills and Porter Ranch, specifically those bounded by Rinaldi Avenue, Balboa Boulevard, De Soto Avenue, and the foothills. More precisely, residents living north of Rinaldi Street or the 118 Freeway (whichever is further north) and west of Balboa Boulevard are directly impacted. An estimated 9,000 customers are currently without service.
