Our Water Distribution Systems

Potable Water Supply Services
The Lake County Public Works Department owns and operates twelve public water supply distribution systems. The employees who maintain these water systems are certified under the Illinois Environmental Protection Agency (IEPA) Drinking Water Operator Certification Program. Water quality is monitored and samples are tested in accordance with strict United States Environmental Protection Agency (USEPA) technical review criteria.

Arden Shores (11)


Serves a small community with a single well. The well produces about 30 gallons per minute from a water bearing aquifer 280 feet below ground. 2-inch diameter water distribution piping interconnects the well with underground storage tanks to form a unified water supply and distribution system. The system was constructed in 1953 and was not originally provided with many modern day features now required by the EPA in the design of new water distribution systems. To comply with IEPA requirements, the County added a chemical feed system to disinfect and add chlorine to the water.

Brooks Farm (2)


This unified water supply and distribution system includes two wells, iron removal treatment, an elevated water storage tank and a network of water mains. The two wells and the iron removal treatment facility are located on Brooks Farm Road at Needlegrass Drive. Both wells are drilled into a water bearing sand and gravel aquifer located 130 feet below ground. Iron removal treatment is provided to remove excess natural iron concentrations. The elevated water storage tank is located at the north end of Barberry Court and has a capacity of 350,000 gallons. The water main network includes three miles of pipe connecting the wells and the elevated tank.

Countryside Lake (6)


Four wells serve this community. One is located on Thorntree Road, a second is on Lakeview Parkway at Countryside Lake Drive, and the remainder are south of Midlothian Road at Countryside Lake Drive. Three of the four wells reach into water bearing aquifers of limestone or sand and gravel formations 200 feet below ground. The other is drilled into a sandstone aquifer over 800 feet deep. The combined capacity of our wells exceeds the average daily usage by 400%. A network of water mains over 12 miles in length interconnects the well sites with a 250,000 gallon elevated storage tank.

Forest Lake (8)


This community receives its water from groundwater supplied by Aqua Illinois, Inc. The Aqua Illinois water system, located at the intersection of Midlothian and Old McHenry Roads, includes two groundwater wells that produce a total of 780 gallons per minute, an ion exchange system to treat the water supply, and a 370,000-gallon water storage reservoir. The water main network that serves the subdivision includes 0.9 miles of water main pipe interconnecting the Aqua wells and the storage reservoir.

Fox Lake Hills (1)


There are two wells serving this community, located on Lehmann Boulevard and on Lincoln Drive. Both wells are drilled into a water bearing sand and gravel aquifer 130 feet below ground. At the Lincoln Drive well house, treatment is provided to remove most of an excessive natural iron concentration. A network of water mains connects the two well sites with a 150,000 gallon elevated tank.

Grandwood Park (4)


This community is served by nine wells. They are located on Grandwood Drive (3), Geier Street, Center Street, Hutchins Road, Woodland Terrace (2) and Deer Trail Drive. Seven of the wells reach into a water bearing sand and gravel aquifer 150 feet below ground. The eighth well is drilled into a sandstone aquifer 1000 feet deep. The ninth well at Grandwood Drive and Hutchins Road is drilled to a depth of 1365 feet. A network of water mains interconnects the dispersed well sites with elevated storage and two ground level reservoirs with a total storage volume of 525,000 gallons.

Hawthorn Woods (7)


The original Hawthorn Woods water system was constructed in 1951. This system was replaced in 2010 with a new distribution system and now receives its water supply from Aqua Illinois, Inc. The Aqua Illinois water system, located at the intersection of Midlothian Road and Old McHenry Road, includes two wells that produce a total of 900 gallons per minute, an ion exchange system to treat the water supply, and a 370,000-gallon storage reservoir.

Highland Lake (3)


Two wells serve the Highland Lake system. One is located on North Circle Drive and the other on South Circle Drive. The wells are drilled into a water bearing limestone aquifer 300 feet below ground. 4-inch and 6-inch diameter water distribution piping interconnects the two wells and storage tanks.

Knollwood (10)


Water for this distribution system is purchased by Lake County from the Central Lake County Joint Action Water Agency (CLCJAWA), an intergovernmental cooperative formed by the communities it serves. The water is pumped from Lake Michigan and treated by CLCJAWA at the Paul M. Neal Water Treatment Facility in Lake Bluff. More than 150 million gallons of water were delivered to 1,050 customers in the Knollwood-Rondout, South Bradley Road and Countryside Manor service area last year. The delivery system includes 34 miles of water main and a water storage reservoir holding one million gallons, or three times our daily demand. As added reliability in emergencies, an interconnection has been constructed to our water system in Vernon Hills.

Pekara (12)


There are five wells serving this community. They are located on Juneway Avenue, Pekara Drive at Walnut Drive (2), Pekara Drive at the Reservoir and north of Penguin Lane. Four of the five wells reach into water bearing limestone aquifers 150 feet below ground. The other is drilled into a sandstone aquifer 900 feet deep. The combined capacity of these wells exceeds the average daily usage in the service area by over 300%. A network of water mains 12 miles in length connects the five well sites with a 600,000-gallon ground level reservoir to form a unified water supply and distribution system.

Vernon Hills (9)


Water for this distribution system is purchased by Lake County from the Central Lake County Joint Action Water Agency (CLCJAWA), an intergovernmental cooperative formed by the communities it serves. The water is pumped from Lake Michigan and treated by CLCJAWA at the Paul M. Neal Water Treatment Facility in Lake Bluff. More than 750 million gallons of water were delivered to 6,500 customers in Vernon Hills last year. The delivery system includes 90 miles of water main and six storage reservoirs holding 3.8 million gallons, or twice our daily demand. As added reliability in an emergency, the former well water system is available as a back up to the Lake Michigan supply.

Wildwood (5)


Water for this distribution system is purchased by Lake County from the Central Lake County Joint Action Water Agency (CLCJAWA), an intergovernmental cooperative formed by the communities it serves. The water is pumped from Lake Michigan and treated by CLCJAWA at the Paul M. Neal Water Treatment Facility in Lake Bluff. More than 370 million gallons of water were delivered to 4,200 customers in Wildwood last year. The delivery system includes 46 miles of water main, one water tower, and two storage reservoirs holding 1.6 million gallons, or two times our average daily demand. As added reliability in an emergency, the former well water system is available as a backup to the Lake Michigan supply.
