Bernstein v. City of New York, 69 N.Y.2d 795 (1987)
A municipality is not an insurer of its water main system and has a duty to inspect a utility’s activities near water mains only if those activities are considered dangerous or if there is a warning of a possible defect.
Summary
This case addresses the scope of a municipality’s duty to inspect and maintain its water mains. The Court of Appeals held that the City of New York was not liable for damages caused by a water main break because the installation of nearby utility ducts by Consolidated Edison (Con Ed) in 1926 did not pose an obvious risk to the water mains, and the city had no warning of a possible defect requiring it to conduct tests for anaerobic bacterial corrosion. The court reasoned that imposing a duty to conduct widespread testing without such a warning would be an onerous burden.
Facts
In 1926, Consolidated Edison (Con Ed) installed ducts near the City of New York’s water mains. A water main subsequently broke, causing damage. The plaintiffs claimed the city was negligent in failing to maintain and inspect its water mains, particularly in light of Con Ed’s excavation and the potential for anaerobic bacterial corrosion.
Procedural History
The lower court’s decision was appealed to the Appellate Division. The Appellate Division’s order was appealed to the New York Court of Appeals.
Issue(s)
1. Whether the City of New York had a duty to inspect its water mains at the time Consolidated Edison installed ducts nearby in 1926.
2. Whether the City of New York was negligent in failing to conduct tests to discover anaerobic bacterial corrosion in its water mains.
Holding
1. No, because the installation of pipes by trained utility employees ordinarily poses no risk to existing water mains.
2. No, because unless there is some warning of a possible defect, the public or private supplier of water is not obligated to tear up the streets to inspect its pipes; the city had no such warning.
Court’s Reasoning
The court relied on the principle that while a municipality is responsible for maintaining and repairing its water mains, it is not an insurer of its system, citing Jenney v. City of Brooklyn, 120 N.Y. 164. Regarding the duty to inspect, the court referenced De Witt Props. v. City of New York, 44 N.Y.2d 417, stating that the city has a duty to inspect a utility’s activities only if those activities can be considered dangerous. Because Con Ed’s duct installation posed no obvious risk, the city had no duty to inspect at that time.
Regarding the claim of negligence for failing to conduct tests for anaerobic bacterial corrosion, the court again cited De Witt Props. v. City of New York, stating, “unless there is some warning of a possible defect the public or private supplier of water is not obligated to tear up the streets to inspect its pipes.” While the city could have conducted tests without tearing up the streets, the procedure would have been onerous, requiring drilling test holes along thousands of miles of pipelines and analyzing soil samples. The court found that imposing such a burden without a significant warning of a possible defect was neither necessary nor desirable. Since there was no warning, the city had no duty to conduct tests.
