Water Treatment Plant Expansion

The most recent expansion of the Nicholasville Water Treatment Plant, completed in 2010, increases the capacity from six million gallons a day to nine million gallons per day. This expansion also improves water quality and meets new, more stringent, EPA requirements.

Capacity improvements include:

• Addition of a new four million gallon per day raw water intake pump and safety and maintenance improvements to the pump platform.
• A two stage chemical mix facility.
• A new three million gallon per day train of conventional vertical flocculation and rectangular sedimentation basin.
• Five new filters to provide up to twelve million gallons per day of filtration capacity.
• Two new 300,000 gallon clearwells.
• Facility and office renovations.

Water Quality improvements include:

• Bulk-feed powdered activated carbon facility to absorb TTHM precursors.
• Aqueous ammonia system for future chloramine disinfection. Right now, this will be used for a sodium permanganate feed system for pre-oxidation of TTHM precursors.
• More efficient computer controlled air and water backwash systems for more effective filter cleaning.
• Additional tube settling modules for lower turbidity discharge from the sedimentation basins.
• Replaced the 20 year old SCADA computer system with a newer system with more capabilities.
• A bulk sodium hypochlorite disinfection facility to replace the chlorine gas disinfection facility
