The Princeton Public Water Supply includes quality and quantity plus treatment and distribution.

The City of Princeton is located at the intersection of 3 ancient bedrock valley systems. The ancient Mississippi, Paw Paw (Troy), and Rock Valley's make up these systems. This aquifer is virtually untapped and provides a precious resource for this community.
Water Tower
Filtration Plant
The City of Princeton Water Filtration Plant is an iron removal and softening plant. It was first constructed in 1930 as a 3 basin conventional lime softening system.

In 1964 an Upflow Solids Contact Unit and more filters were added. The last 10 years has seen a complete update of equipment and process culminating with the construction of a 1.5 million gallon water tower in 2005.

Currently, the City of Princeton Water Department maintains 58 miles of water main.
