Element 3: Infrastructure Protection and Resilience

Tasks for Element 3:

  • Construct and retrofit critical facilities with sustainable communications, energy, water, and waste infrastructure in appropriate locations and to a standard of climate resilience to withstand events over the anticipated life of the structure. Infrastructure resilience measures reduce disruption, incapacitation, or loss of use of critical health care facilities.
  • For less critical facilities: design for safe closure prior to an event with the ability to resume services within 48 to 96 hours following a major event.

Examine facility infrastructure

New York University (NYU) Medical Center (in center of photograph) sustained significant infrastructure damage from the storm surge that accompanied Hurricane Sandy. Now, the Center is working with federal agencies to coordinate plans for improving its flood resilience. As they work to develop protection for the facility, the groups may come up with options that can improve the surrounding ecosystem.

Infrastructure protection and resilience is a key element of health care facility operation through extreme weather events. In Hurricane Sandy, the failure of both grid power and emergency generators forced hospital evacuations. While generators were located above flood elevations, critical infrastructure components—fuel pumps, fuel tanks, electrical switchgear—were not. This element examines energy, water, and waste infrastructure, as well as fire protection and communication systems. All of these components are necessary to continue to provide care and/or safely “shelter in place” during and after an extreme weather event.

Uninterrupted energy supplies are required to maintain operational health care facilities during and following an extreme weather event. While all hospitals include emergency generators for temporary emergency power supplies, extended grid power outages are testing the limits of this technology, and emergency generator plants may be situated in vulnerable locations. Increasingly, hospitals are investing in on-site power generation through combined heat and power technologies to improve resilience. In addition to power interruption, loss of climate control systems (heating and air conditioning), air filtration, building pressurization, and other key mechanical performance measures may lead to the need to evacuate the facility.

Secure access to water

Access to reliable potable and process water supply is a key element of health care resilience. There is no national standard for quantity of reserve backup; one of the key challenges with fixed-quantity emergency water supplies is accurately estimating demand. Storage of large quantities of water is often difficult and impractical, but ensuring 24/7 availability of water delivery is equally challenging. A range of measures can improve water supply resilience: dual water sources (i.e., on-site wells), water conservation, on-site rainwater harvesting, and reclaimed water reuse systems. Municipalities in drought-prone regions are installing large-scale municipal reclaimed water systems to meet the process (non-potable) water needs of their communities. In hospitals, up to 70 percent of total water use is for non-clinical care uses. Finding reliable alternative sources of water is a key element of enhanced resilience in a future with stressed potable water supplies.

Emergency Water Supply Planning Guide for Hospitals and Healthcare FacilitiesHealth care facilities should develop an Emergency Water Supply Plan (EWSP) to prepare for, respond to, and recover from a total or partial interruption of the facilities’ normal water supply. Because a health care facility must be able to respond to and recover from a water supply interruption, an EWSP provides the guidance to assess water usage, response capabilities, and water supply alternatives.
