Project Title:
UltraViolet (UV) Radiation WWTP Disinfection Retrofit

Project Description:
Lexington is pursing a project to eliminate the use of chlorine to disinfect watewater effluent, converting the disinfection process at both Lexington WWTPs to UV radiation. Currently, both the Town Branch WWTP (rated capacity 30 MGD) and the West Hickman WWTP (rated capacity 33.8 MGD) use gasous chorine stored in one ton cylinders. Total maximum storage is > 20 tons. Both plants use sulfur dioxide to remove residual chlorine below discharge limits. The total maximum storage for sulfur dioxide is > 10 tons.

Need For Project: Briefly describe how this project promotes public health or achieves and/or maintains compliance with the Clean Water Act or Safe Drinking Water Act:
Eliminating gaseous chlorine from the WWTP process eliminates toxic gas exposure risks for operators and the public. Eliminating the use of chlorine in the wastewater effluent disinfection process reduces the probablity of forming disinfection byproducts in drinking water supplies.

Project Alternatives:

Alternate A:

Note: If project includes the construction of a new treatment plant or upgrade to existing plant, please explain regionalization options here.

Switch to an alternative disinfection chemical that has a higher operating cost than
gaseous chlorine. The alternative chemical would likely also have different exposure
risks for operators and the public

Alternate B:

Do nothing

Green Infrastructure:

Green stormwater infrastructure includes a wide array of practices at multiple scales that manage wet weather and that maintains and restores natural hydrology by infiltrating, evapotranspiring and harvesting and using stormwater. On a regional scale, green infrastructure is the preservation and restoration of natural landscape features, such as forests, floodplains, and wetlands, coupled with policies such as infill and redevelopment that reduce overall imperviousness in a watershed. On the local scale, green infrastructure consists of site and neighborhood-specific practices, such as:

Component		Cost
Item 1:	Implementation of green streets.
Item 2:	Wet Weather management systems for parking areas.
Item 3:	Implementation of comprehensive urban forestry programs.
Item 4:	Stormwater harvesting and reuse.
Item 5:	Downspout disconnection.
Item 6:	Comprehensive retrofit programs designed to keep wet weather discharges out of sewer systems.
Item 7:	Establishment or restoration of riparian buffers, floodplains, wetlands or other natural features.
Item 8:	Management of wetlands.
Item 9:	Purchase of land or easements on land that has a direct benefit to water quality.
Total Cost:

* Indicates a business case may be required for this item.
