Lake County Public Water District Grows With the Helpof B&W Control Systems Integration and InduSoftUpgrades to Lake County Public Water District SCADA system addedredundancy, remote monitoring, and current PLC communications • InduSoft Web Studio (IWS) made upgrading from a system installed almost 10 years prior extremely easy. • InduSoft Web Studio proved to be the ideal solution for the current requirements and planned future upgrades of the Lake County Public Water District. • The developer found IWS “very intuitive, straightforward, and everything proceeded with a minimum of time spent in additional development.” Figure 1: Clear, informational and easy to use interface for pump house monitoring Background B&W Control Systems Integration specializes in Municipal water districts are integral aspects of the municipal clientele and does everything from facility infrastructure of any city. Water and wastewater automation to water and wastewater SCADA and treatment are absolutely vital for any city, and in remote SCADA applications. The Lake County water/ order to meet both state and federal regulations, water wastewater treatment SCADA application was built treatment must be carefully monitored. From the using InduSoft Web Studio, and it presented B&W water source to the tap, there is a complex process with an opportunity to work with new SCADA that city water supplies must go through to maintain development software. safety and reliability. Oversight of the process is an important way to ensure that water supplies make it The Challenge through the entire process while adhering to health The application monitors a water treatment plant that and safety regulations and reliably providing water to services Zion, Illinois, among other nearby towns.

Low lift The Lake County Public Water District, which serves pumps bring water into the plant, and then take it to the City of Zion, the Village of Winthrop Harbor and the main water facility where it goes through three the Illinois Department of Natural Resources (Illinois different clarifiers. During this stage of the process, Beach State Park and North Point Marina) on a non- profit basis, recently found their system in need of an upgrade. B&W Control Systems Integration was chosen for this large municipal project.

No additional modules or protocols needed to be purchased to connect directly with the new hardware. We only had to install the B&W added some redundancy features to the system during the upgrade. Before, the InduSoft Web Studio new software, copy the data based SCADA system resided on one server. The new architecture includes two rack servers that act over and plug in the new as a redundant pair. The licenses included with these redundant servers also offered Lake County two information, and everything ” additional remote thin client viewers that clients can use to connect to the system. went off without a hitch. This web connectivity was a great addition to the — Jim Gramhofer, B&W Developer upgrade. With the thin client viewers, the plantof the software with compatibility in mind, meaning that operators and supervisors can monitor the processeven applications developed in the first iteration of InduSoft from remote locations, such as offices or homes.

This ensures that it’s easy to take the SCADA system withallows plant owners to upgrade equipment such as PLCs and the personnel wherever they go, and helps ensure thatcomputers with the assurance that development time used alarms are addressed as soon as possible.

One aspect of the upgrade that went especially wellAnother benefit of using InduSoft for the upgrade was included the changing of tag names to include more Figure 5: Clarifier status is monitored and displayed on a representation of the physical layout.

Gramhofer, who was new to developing in InduSoft Web Studio said “It’s easy to work with InduSoft from the very beginning, and very intuitive. The development was straightforward, and even without the class, it’s easy to pick up the software very quickly.” A key point that B&W noted in working with InduSoft Web Studio was the rich feature set that For more information contact your local distributor or InduSoft directly at info@indusoft.com or 877-INDUSOFT (877-463-8763) or 512-349-0334. ©2011 InduSoft, Inc.
