A water main break on 700 South in Tooele buckled the pavement Monday, opening a hole in the roadway that swallowed a car as police and neighbors gathered around the scene. The city shut off water to an estimated 10 to 15 homes while crews scrambled to assess the damage and figure out what caused the aging pipe to fail.
The break sent water rushing downhill before the ground cracked open, according to KMYU. Tooele City Public Works said the burst line was 16 inches in diameter and at least eight to ten years old. One witness described the scene as a mess, telling the outlet the whole thing was scary to watch unfold.
Authorities responded and closed a section of 700 South while repairs got underway, and the car that had sunk into the hole was eventually towed out. The city said the cause of the break was still being determined as crews evaluated how it happened and what repairs would be needed.
City Crews Go Door-to-Door With Bottled Water
With water service cut to the affected homes, the city sent workers door to door to hand out bottled water to residents left without a working tap. Officials said they expected service to be restored within four to eight hours of the shutoff. A city spokesperson framed the break as part of the ordinary wear on an aging system, saying incidents like this happen from time to time as Tooele continually upgrades and replaces its infrastructure, per the same account.
That framing lands differently for anyone who has watched money flow toward this exact stretch of road. Just over a year before the pipe gave way, the Tooele City Council approved a $1,135,688 contract with Strong Excavation LLC to replace a 16-inch water transmission line on 700 South between State Route 36 and Coleman Street, with an additional $57,000 contingency fund approved for changed conditions. Tooele City Public Works announced in July 2025 that construction on that replacement project had begun, with an expected 90-day timeline to finish the work. Whether Monday's break struck a newly replaced segment, an untouched stretch of old pipe, or something in between is not yet clear from available city statements.
Years of Rate Hikes Aimed at Aging Pipes
Tooele residents have already been paying more for water specifically to address this kind of failure. The city implemented a multi-year utility rate increase starting in June 2024 and continuing through a June 2025 adjustment, a move that followed an external 2024 rate study recommending gradual five-year hikes to fund repair and replacement of aging municipal infrastructure. Under Tooele City Code Section 9-4-6, the city is responsible for maintaining culinary water service pipes up to and including the meter, while property owners are on the hook for lines running from the meter into their homes.
The city's underlying water network is extensive and, in parts, old. Tooele's 2021 Drinking Water System Master Plan put the culinary water network at roughly 190 miles of pipeline ranging from 2 to 24 inches in diameter, with existing transmission assets valued at $27.8 million. Monday's failure was not the first on this corridor: Tooele City experienced a previous water main break along 700 South in July 2019 that temporarily cut water service for residents between Coleman Street and 780 West, requiring emergency repairs at the time.
Growth and New State Mandates Add Pressure
Tooele's population growth adds another layer of strain to a system already showing its age. Demographic projections in the Tooele County General Plan estimate the city's population will grow from nearly 40,000 in 2020 to 49,855 by 2030, growth that accounts for more than 80 percent of the county's overall population increase. State lawmakers have taken notice of the broader issue as well: Utah Code § 10-20-404 required municipalities statewide to adopt a water use and preservation element into their general plans by the end of 2025, explicitly addressing infrastructure asset management and system leakage, according to the Utah Division of Water Resources.
Weather may have played a role in weakening the ground around the pipe, though no official cause has been confirmed. Heavy summer monsoon storms brought high rainfall and localized flood advisories across Tooele County in mid-August, according to KSL, creating runoff and drainage strain on roadways throughout the region that same week. It remains an open question whether that saturation contributed to Monday's break, since the city has said only that the cause is still being determined.
