Knowles Road Water Tower

The Village of Gurnee is currently in the process of building a water tower at the corner of Knowles Road and Rollins Road. This tower is a multi-year project that will result in better water pressure reliability for residents west of I-94. To answer questions about the water tower, we have put together an FAQ for residents to learn more about the project.

For more information regarding the new water tower please contact the Engineering Division at 847.599.7586.  

Knowles Water Tower FAQ

  1. Why the need for the new water tower?
  2. Current System & Existing Conditions

    Currently the Village receives its water from CLC JAWA (Central Lake County Joint Action Water Agency) and is able to provide up to 6.2 million gallons of above ground storage with five facilities. In spring 2018 one of the five facilities will be removed from the system and taken out of service. This will drop the total storage to 6.0 million gallons or 1.7 days of average consumption. Additionally, the Village has two wells and one service connection with the City of Waukegan that are utilize in emergency situations for additional supply.

    Overall the Village is able to provide a very high level of service to its residents in terms of high water pressure and reliability. The average water pressure throughout the community is between 70 & 80 pounds per square inch. The western limits of town, where the elevation of the grade is highest above sea level, neighborhoods have the lowest water pressures between 30 & 50 pounds per square inch.

    Conclusion

    By building the water tower on the higher side of the Village we will be able to utilize gravity to pressurize the water distribution system. This will ultimately improve the water reliability and pressure for residents in the far western sections of Gurnee. The tower will also provide additional water storage for the Village increasing the overall capacity to approximately 8 million gallons or 2.2 days of average consumption. This benefits the entire community in emergency situations when supply does not equal demand or when supply has been temporarily disconnected. The Village will be able to provide water for the entire community for an extended time until supply can be restored. 

  3. Where exactly is the new water tower being built?
  4. The Knowles Road Water Tower is being installed at 1525 Knowles Road on a vacant parcel owned by the Village, near the end of Knowles Road and adjacent to Rollins Road. The below map shows the exact location of the new tower.

  5. When will the water tower be built?
  6. The Village has approved plan designs for the Knowles Road Water Tower to be executed in 2018, with construction of the tower scheduled to begin late summer 2018 and completed in 2020.

  7. What will the tower look like?
  8. The Knowles Road water tower will be a 2,000,000 million gallon structure. To put the capacity in perspective, the now-defunct Old Grand Water Tower holds 1/10th that amount or 200,000 gallons of water.

    The design of the new water tower will be either a Water Spheroid Tank, similar to other water towers in Gurnee, or a composite concrete base water tower. Below are two examples of a spheroid and composite water towers.

  9. How much will this tower cost? How is it being paid for?
  10. Constructing a new water tower is no simple feat. While the water supply infrastructure is already in place there is still considerable construction and engineering detail that needs to be addressed for a new water tower. The current project estimate is around $6 million to complete the project. The project will be funded from a combination of fund balance reserves and a low interest IEPA loan.
