The water system fails and the tribe searches for water

The failure of the water system and the tribe’s search for water mark a decisive break with the infrastructure that had made urban life seem effortless. A flaw hidden in the aqueduct grows, over years without repair, into a breach that drains the reservoirs; when the community finally confronts the empty basin, survival depends not on restoring the old network but on learning where water still runs nearby.

A Flaw Hidden in the Aqueduct

The crisis begins with a steel pipe section in the main aqueduct, part of the complex of dams, tunnels, aqueducts, and reservoirs that carried mountain water to the cities. Imperfections were visible when the pipe was manufactured, but it passed inspection at the end of a workday, when the inspector’s senses were dulled and his judgment impaired. The flaw did not immediately bring the system down. The pipe was installed and worked without difficulty, and shortly before the Great Disaster a foreman noticed a slight leak that a welded patch could have repaired. But the leak’s gradual growth went unattended: after the Disaster, no one passed that way again.

At first, the water escaping from the pipe left only a small green patch in dry summers, drawing birds and small animals. Over five or ten years, a dozen fine jets appeared; five years later, the leak had become a stream, the only summer stream in that foothill region. Cattle drank there, and their trampling helped erode the already soft, muddy ground into a gully. Meanwhile, rust weakened the pipe from outside and the water corroded it from within. Eventually the gully’s erosion triggered a mudflow beneath the concrete pier supporting the water-laden pipe. As the pier settled, the load shifted onto the weakened steel, opening a long rent. The escaping water further undermined the footing, the pipe tore again, and the flow swelled into a small river.

The Reservoirs Run Down

The aqueduct breach meant that water no longer flowed into the reservoirs, but it was only one part of the loss. Water continued escaping through thousands of leaks, faucets left running at the time of the Great Disaster, and major breaks caused by the earthquake. The reservoirs’ stored supply steadily diminished. Heavy rains in the week after New Year’s slowed the fall, but an unusually early midwinter dry spell renewed the decline. A gauge that had recently registered twenty feet now showed only a thin skin of water across the reservoir bottom.

The scale of the failure becomes tangible in a household scene. Ish enters the kitchen to find Josey holding a kettle beneath a faucet that produces only a trickle. He assumes the plumbing needs repair and sends her to fill the kettle from an outside faucet. That small workaround postpones the recognition that the municipal supply is disappearing, but it cannot reverse the loss. A system that had delivered water through a vast network has become a dwindling store, then an empty basin.

The novel places this crisis beside other unattended failures. The electric system, too, initially continues after the Disaster: its generators remain in operation, and the network can compensate when a wire or power-house fails. Yet its governors require periodic attention, and as their oil supplies run low, individual generators stop and the remaining units bear increasing strain. On San Lupo Drive, leaves block a drain-pipe; rainwater crosses the street, floods the former Hart lawn, and cuts a small gully through the rose garden. These failures differ in scale, but each exposes the same dependence: infrastructure persists only while people perform the ordinary maintenance that keeps small faults from becoming larger ones.

The Empty Basin and a Change of Knowledge

When the community reaches the reservoir, the outlet-pipe stands up into the air above an almost empty expanse. Only a skim of water remains in two or three low places. Ezra’s brief response, “That's that!”, gives voice to the finality of what the group sees: the stored supply is gone, and the old expectation of water at the tap no longer offers a practical solution.

The older members initially think like former city-dwellers, looking for bottled water in stores and warehouses. They soon judge that, even through the approaching dry season, the region is not a desert: small streams in the gullies must be sustaining the cattle and other animals. The more consequential discovery is that the younger generation already knows the local water landscape better than the elders. Ish, though he had been a geographer, can recall streets and intersections but cannot readily name a nearby spring or dependable stream. The youngsters can point out where water is running in that season, where pools or springs can be found, and how to reach them, even without locating them by street names.

Walt instructs his father about a stream in a little gully that passes beneath San Lupo Drive through a storm drain, a route Ish had scarcely noticed. The contrast is not simply between ignorance and knowledge: the adults remember the region through the organized map of roads, while the children have learned its seasonal waterways through direct familiarity with the surrounding land. The failure of the city’s network makes that difference immediately useful.

Work After the System

Initial consternation gives way to activity. Some of the youngsters take dog-teams and five-gallon cans to fetch water from the nearest spring. Older members begin digging holes and setting up outhouses. The response is practical and collective, but it also makes clear that replacing a failed system is laborious: the group’s enthusiasm lasts for several hours, while steady pick-and-shovel work is unfamiliar to them.

The search therefore changes more than the source of the community’s water. It exposes the hidden labor behind the conveniences of the former network, makes local environmental knowledge essential, and redirects the group from dependence on centralized supplies toward streams and springs they must find and reach themselves. The aqueduct fails through a chain of delayed consequences—an overlooked manufacturing defect, an unrepaired leak, corrosion, erosion, and a shifting support. The community’s answer begins at the opposite scale: with a child who knows where a stream runs, a can carried by a dog-team, and people learning to work with the water that remains.
