Utility Services in a Zombie Apocalypse: How Long Would They Last?

In a zombie apocalypse scenario, the reliability and duration of various utility services can significantly impact survival. Understanding how long these services might last can help prepare for the worst. Here, we break down the estimated durations of water, natural gas, electricity, regular gas fuel stations, cable and satellite TV, internet, and sewer service.

Water Supply

Duration: A few days to weeks.

The longevity of the water supply would depend on the extent of the disaster, the operational status of infrastructure, and the response of utility companies. Even if the infrastructure remains structurally intact, municipal water systems may cease to function without personnel to maintain them. Add to that the issues of water contamination and the lack of power for purification processes, which would lead to shortages rapidly.

Natural Gas

Duration: Weeks to months.

Natural gas lines are less reliant on electricity, making them more resilient. However, without ongoing maintenance, issues like leaks and pressure problems could emerge, leading to service interruptions. The natural gas infrastructure is generally better prepared to handle such long-term disruptions due to the nature of pipeline systems.

Electricity

Duration: Days to weeks.

Electricity is the backbone of modern infrastructure. Power plants and the grid are crucial components. While electricity could potentially last longer with the aid of power plants that can be kept running, widespread outages would occur quickly due to a lack of personnel and fuel shortages. Additionally, the grid is highly interconnected, making it susceptible to cascading failures once a key component is down.

Regular Gas Fuel Stations

Duration: Days to weeks.

Gas stations, which are critical for other forms of transportation, would eventually run out of fuel as supply chains break down and electricity for pumps fails. Accessible fuel that remains operable would diminish rapidly if transport is disrupted. Even then, the availability would be limited as the infrastructure supporting these stations would be affected.

Cable and Satellite TV

Duration: Days to weeks.

Cable services require electricity and infrastructure that would likely fail quickly after an initial shock. Satellite TV, on the other hand, may last longer if the satellite systems remain operational and users have power. However, without ongoing maintenance, issues would arise. Satellite TV’s resilience is also compromised by the need for an uninterrupted power supply.

Internet

Duration: Days to weeks.

Internet services, like cable and satellite, depend heavily on electricity and infrastructure. Loss of power would lead to immediate cessation of internet access. Even if some systems remain operational, they would degrade without proper maintenance. The infrastructure is interconnected, making it vulnerable to widespread disruption.

Sewer Services

Duration: Days to weeks.

Sewer systems are critical for sanitation but rely on electricity for pumping and treatment. Without power and maintenance, these systems would quickly become overwhelmed, leading to health hazards. The accumulation of sewage in residential areas would pose significant risks to public health.

Summary: In a zombie apocalypse, most utilities are likely to last a few days to a few weeks. The natural gas infrastructure might endure longer due to its inertia, but all services are vulnerable to the breakdown of infrastructure, lack of fuel, and the absence of maintenance personnel.
