San Diego keeps water control after court rejects PrimeWater’s appeal

Water services in San Diego remain under city control after a court ruling blocked PrimeWater Infrastructure Corporation’s attempt to resume operations. The suspension stems from an executive order issued last November, halting the company’s activities over service complaints and environmental violations.

On 17 November 2025, Mayor Vilma Caluag signed Executive Order No. 87, revoking PrimeWater’s business permit. The decision followed repeated consumer grievances about poor water service and breaches of the city’s 2008 Environmental Code, specifically regarding water quality standards.

PrimeWater responded by filing a petition for a temporary restraining order and preliminary injunction through its lawyer, Atty. Romulo Macalintal. The company sought to overturn the suspension and restart operations. However, the court rejected the request, leaving the order in place.

With the legal challenge dismissed, the City of San Diego’s local government continues to oversee water utility services. PrimeWater’s operations remain halted until further notice.

The court’s decision upholds the suspension of PrimeWater’s services in San Diego. Residents will keep receiving water from the city’s local government while the company remains barred from operating. The ruling reinforces the enforcement of the city’s environmental and service quality regulations.
