When the Grid Goes Down, Your Water Shouldn’t

Most homeowners don’t think about their water supply until it’s gone. A wildfire evacuation order, an extended power outage, a municipal system failure after an earthquake — these aren’t hypothetical scenarios. They’re the events that reveal, in the worst possible moment, that a home has no backup water whatsoever.

A reliable backup water supply is one of the most practical and overlooked forms of household preparedness. WaterFence makes it easier than ever to build that resilience into your property — without sacrificing an inch of yard space or the look of your landscape.

Why Backup Water Supply Matters More Than Ever

Municipal water systems are more vulnerable than most people realize. Aging infrastructure, increased wildfire activity, flooding events, and extended power outages can disrupt water service for hours, days, or longer. FEMA recommends storing at least one gallon of water per person per day, but that guidance was designed for short-term drinking needs — not the broader demands of household function.

A true backup supply needs to cover drinking and cooking, sanitation, fire suppression support, and garden irrigation for food crops. When you add those needs together, the math changes quickly. A family of four can consume 80 to 100 gallons per day across all uses. Stored cases of bottled water simply don’t scale to that reality.

Rainwater harvesting offers a fundamentally different solution: a continuously replenishing supply that fills automatically every time rain falls, costs nothing once installed, and is available entirely independently of municipal infrastructure.

How WaterFence Delivers Backup Capacity

WaterFence is a rainwater storage system designed to look exactly like a traditional wood privacy fence. At approximately six feet tall, seven feet long, and 14 inches deep, each panel stores a meaningful volume of water while blending seamlessly into any residential or commercial property. A spigot at the base provides direct access. The system connects to existing roof gutters, so it fills passively — no pumps, no complicated plumbing, no ongoing maintenance burden.

For backup water supply purposes, this form factor matters in several important ways.

First, capacity scales with perimeter. A standard fence run along the back of a property can store hundreds of gallons, enough to sustain a household through a multi-day disruption with water to spare. Unlike a single above-ground tank, WaterFence distributes storage across a functional boundary you already need.

Second, the water is gravity-fed and accessible at ground level. In a grid-down scenario where electric pumps may not function, a simple spigot is far more reliable than a pressurized system. Fill a container, fill a bucket, connect a hose — no power required.

Third, because the system fills from the roof, it stays topped off throughout the rainy season with no effort from the homeowner. A properly sized WaterFence installation can enter every dry season, or every storm season, already full.

Backup Supply for Fire-Prone and Rural Properties

In wildland-urban interface communities — the neighborhoods where residential development meets open land — backup water supply takes on additional urgency. Firefighters operating in these zones frequently work from onsite water sources when hydrant access is limited. A property with several hundred gallons stored at the fence line can provide meaningful suppression support in the critical early minutes of a structure fire.

For rural properties on well systems, a power outage means no water at all. WaterFence provides a gravity-fed reserve that operates entirely off-grid, making it a natural complement to solar panels, backup generators, and other resilience investments.

Preparedness That Looks Like a Fence

Emergency preparedness doesn’t have to look utilitarian. WaterFence stores the water your family needs quietly, attractively, and exactly where a fence would already be. When the grid goes down, it’s already there — full, accessible, and ready.
