California hospitals and acute care facilities are under increasing pressure to ensure emergency preparedness in the face of droughts, seismic activity, and infrastructure disruptions. The California Department of Health Care Access and Information (HCAI) requires facilities to meet the NPC-5 (Non-Structural Performance Category 5) standards, including a water rationing plan that guarantees a minimum 72-hour on-site water supply for essential operations. The NPC-5 requirements include potable and industrial/process water used to operate the facility.
National Storage Tank (NST) is based in Santa Rosa and has satellite offices throughout the state to serve the water storage needs of every Hospital and Acute Care facility from San Diego to Los Angeles and north to San Francisco and Sacramento. Rural or Metro, we have the experience to ensure your compliance with this critical preparedness requirement. For the past 20 years, we have been a trusted provider of high-quality, code-compliant water storage solutions that help healthcare facilities across California meet and exceed NPC-5 water storage mandates.
NPC-5 is the highest standard for non-structural components in California healthcare facilities. It ensures that systems critical to patient care—such as water, power, and medical gases—remain operational during and after a disaster. Unfortunately, the lack of water resources during such events led to this new requirement.
For water storage, this means having a dedicated, seismic-rated, and properly engineered system that can store thousands of gallons of potable and non-potable water to sustain hospital operations for at least the 96-hour minimum, including:
Engineered to withstand seismic forces, our bolted steel tanks are customizable in size and layout, with options ranging from 10,000 to over 6,000,000 gallons. They are ideal for above-ground potable and process water storage applications and comply with all NPC-5 expectations.
Perfect for high-purity water applications, our stainless-steel tanks resist corrosion and ensure safe storage for sensitive hospital operations. Our stainless-steel tanks are the finest available, with each meeting or exceeding NSF61, NFPA22, CBC2010, AWWA, UL 142, and API 650 requirements.
Space-constrained? Our underground tanks offer high-capacity water storage without sacrificing above-ground real estate and provide the ultimate visual appeal. UV-resistant and corrosion-proof, each of our Fiberglass-Reinforced Plastic (FRP) tanks is perfectly engineered and proven over decades.
From engineering and permits to installation and inspections, NST provides complete turnkey water storage systems that streamline compliance for all hospitals, small and large, and every rural hospital serving the entire county and sometimes two.
The deadline for NPC-5 compliance is rapidly approaching. By January 2026, each hospital owner must submit to HCAI construction documents deemed “ready for review,” with a final rating achieved at the latest in 2030. Don’t wait until the last minute to implement a water storage solution. Let NST help you prepare with the following:
