Patoka Lake, located in southwest Indiana serves as a drinking water source for more than 65,000 residents across nine counties. The Patoka Lake Regional Water and Sewer District needed to expand and modernize their 5.0 MGD surface water treatment plant, and chose Tonka Water to do the job. Tonka Water assisted in finding the best, most cost-effective solution based on our 60 years of knowledge and experience in the design and implementation of surface water treatment systems.
Treatment begins with the water passing through an induced draft aerator to remove any dissolved gases, before being chemically treated and fed into two TriClear™ clarifiers. After clarification, water is filtered through the space-efficient Tonka Water Centralator™. The Centralator™ is a four-cell cluster gravity filtration system with a central control column. Patoka’s existing equipment and it’s Allen-Bradley controls were rebuilt and incorporated as a part of this project, taking advantage of the existing infrastructure of the plant. The heart of the treatment plant is the Centralator™, including Tonka Water’s Simul-Wash™ backwash system, providing optimal media cleansing while minimizing water usage.
The Patoka Lake plant has been exceeding expectations since start-up and continues to have consistent performance. Tonka Water is proud to have assisted the community in meeting their water treatment goals.
This project features a remote access feature provided by Tonka Water allowing for remote monitoring of plant controls. This technology captures operational performance data in real time creating increased mobility and ease of use for operators. Plant controls can be monitored using a tablet, cell phone or PC via internet access.
