What is the Infiltration Gallery?

The Infiltration Gallery, situated within Water Works Park and adjacent land, has a rich history. The initial 250 feet of the infiltration gallery were constructed in 1884. Today, it has expanded to over three miles in length and thirty feet in depth. The gallery’s primary function is to collect alluvial groundwater, which is then naturally filtered through sand and gravel before being delivered to the Fleur Drive Treatment Plant for further treatment. Remarkably, the gallery has the capacity to produce more than 30 million gallons of water daily.
