Chicagos Water Intake Cribs Are A Marvel That Keep Our Water Flowing

Chicago's water intake cribs, essential for supplying water to five million residents, were established to combat public health issues stemming from contaminated water in the late 19th century. The city moved its water intakes two miles offshore to ensure safety and cleanliness. The construction of the first crib, Two-Mile Crib, began in 1864, allowing workers to dig down 194 feet below the lakebed, with only a seven-inch discrepancy when crews met. Today, only two cribs, Dever and Dunne, remain active, continuing to provide vital water services. These structures are a testament to engineering prowess, having endured for over 150 years.

Megan Vidis and urban planning professor Joseph Schwieterman emphasize their significance and the historical context of their construction. The cribs are a crucial part of the water system for Chicago and 120 suburbs, underscoring their lasting impact on public health and infrastructure. Their ongoing operation highlights the importance of maintaining such historical infrastructure in modern urban settings.
