Project Description
Lake County Public Works (LCPW) completed a study that identified that the Highland Lake water system needs to be modernized to make the system more resilient in emergency situations. As part of this project, LCPW was approached by a smaller, private system with improvement needs and found there is a mutual benefit of a system interconnection. 

Improvements are being constructed in two phases:    

  1. The interconnection of both systems with a water main installed on the north side of Washington Street (substantially complete).    
  2. Water system improvements to provide additional system resiliency, including well pumping capacity and water storage (design underway). The facilities are proposed to be constructed at 34225 N. Lakeside Drive, Grayslake.  

The Phase 1 water main interconnection was substantially completed in 2023, and Phase 2 will be constructed in 2024-2025 pending project readiness. Phase 2 design is underway. Learn more about Phase 1.    

This project is supported in whole by federal award number 21.027 awarded to Lake County by the U.S. Department of the Treasury to improve the Highland Lake Water System. ARPA funds represent 100% of the total project funding.    

Current Phase/Anticipated Schedule: 

Design is underway for phase two and construction of the modernization improvements are anticipated to occur in 2024 and 2025. 

The water storage tank and pump house are proposed to be located at 34225 N. Lakeside Drive, Grayslake. On Nov. 16, 2023, Lake County Public Works presented the project to area residents at the Grayslake Village Hall. View the presentation shown at the meeting. 

In the coming weeks, the Village of Grayslake Plan Commission/Zoning Board of Appeals will consider the land use proposal and the Grayslake Village Board will take final action to approve siting of the facilities.
