Water Supply and Water Sources
Surface water comes from rivers, creeks, streams and reservoirs and may potentially have more pollutants and contaminants than ground water. Ground water comes from below the surface, typically from wells drilled deep into the ground. Ground water may have more mineral deposits than surface water.
Indianapolis Water's supply for customers comes from several sources.
- White River supplies two of the four surface water treatment plants, White River and White River North. Morse Reservoir, near Noblesville, stores water to assure a dependable supply in White River to these plants.
- Fall Creek is another surface water supply. Geist Reservoir stores water to assure an adequate supply in Fall Creek for the Fall Creek treatment plant.
- A number of wells are used intermittently to supplement the supplies to the White River, White River North and Fall Creek plants.
Indianapolis Water also receives some surface water from Eagle Creek Reservoir, which supplies water to the T.W. Moses treatment plant.
Indianapolis Water has four ground water stations that serve smaller portions of its service area: Geist Station, Harding Station, South Well Field and Ford Road plant. These ground water stations treat water pumped from underground water sources called aquifers.
