Water Division
North Peoria Water Resource Evaluation May 2000

The City of Peoria currently utilizes numerous water wells and two water treatment plants (Pyramid Peak and Greenway WTPs) to serve more than 100,000 people in an area greater than 160 square miles.  The population within the City's service area is projected to increase to nearly 300,000 by the year 2040.  This growth will require a significant increase in the available water resources for the City.  The land availability and attractive scenery in north Peoria make this portion of the City ripe for rapid growth and development.  Much of Peoria's population growth is currently occurring in the northern portion of the City today, but the native groundwater supply is limited and potentially unreliable in some areas.  

Hydrogeologic conditions limit the groundwater resources of north Peoria because the area is dominated by basalt, volcanic and granitoid rocks.  These types of geologic formations do not commonly make for prolific aquifers and usually yield minimal amounts of water to wells.  The sediment-filled basins that of the Salt River Valley that comprise the prolific aquifers that produce large amounts of water to wells are limited in extent in the northern parts of Peoria.

The Utilities Department undertook a reconnaissance level investigation of north Peoria's geology and hydrology in 2000.  This investigation culminated in the report NORTH PEORIA WATER RESOURCES INVESTIGATION that was published in May 2000.  If you are interested in obtaining a copy of this report, please contact the Utilities Department Administration at 623-773-7286.
