The City of Frankfort is anticipating new demands and users in its water system and expects to see a 50 percent growth in demands over the next 20 years. The existing water system is at capacity and will not be able to support this growth. Additional source and treatment facilities are needed.
In addition to the need for additional capacity, two of Frankfort’s three elevated water storage tanks need repair. The West Tank has failed coatings and requires updates to meet current AWWA and OSHA regulations. The Jefferson Tank sees low demands relative to other storage tanks in the system. This can result in stagnant water and water quality concerns unless it is carefully monitored by the operators. This can require flushing in the area to turn over water in the tank.
In the distribution system, dead end mains on West CR00 NS and South CR450 W provide water to Frankfort’s highest-demand user and have no redundancy. Additionally, the Indiana Department of Transportation has multiple roadwork improvements projects planned in the City of Frankfort. These projects will require existing water mains in the system to be relocated. Finally, meters in the distribution system are aging, approaching the end of their life cycle, and could be losing accuracy.
The proposed projects include expansion of the Armstrong Road Water Treatment Plant (WTP) and wellfield, County Road 00 Water Main Extension, Water Main Relocations along State Roads 28 and 75, rehabilitation of the West Elevated Storage Tank, and Meter Replacements. A summary of the work for these projects is listed below:
- Wellfield Improvements — Installation of two new wells and raw water transmission in the Armstrong Road wellfield.
- Armstrong Road Water Treatment Plant Expansion — Installation of two new induced draft aerators, one new detention tank, two new pressure fillers and two new high service pumps.
- On-Site Generation (OSG) — Conversion of disinfection method from chlorine gas to on-site sodium hypochlorite generation. Installation of a new OSG building and chemical feed lines.
- Demolition and Improvement of Remote Sites — Demolition of the McKinley WTP and Well Nos. 16 and 17. Installation of control valves at the East and West Tanks.
- CR00 Water Main Extension — Instillation of new 12-and 18-inch water main to connect the dead ends of CR00 and CR450.
- SR28 and SR75 INDOT Water Main Relocation — Relocation of water mains in INDOT project areas to address conflicts and update aged mains.
- West Tank Rehabilitation — Improvements and rehabilitation of the West Tank to repair failing interior coatings and address regulatory concerns.
- Water Meter Replacement — Installation of new meters throughout the distribution system.
- Armstrong Road Water Treatment Plant Improvements — Replacement of variable frequency drives (VFDs), conversion from a dry phosphate to a liquid phosphate feed system, miscellaneous coating improvements, installation of a bulk filling station and site improvements.
The total cost of the project is $13.623 million.
