Abstract:

Lexington Fayette Urban County Government (LFUCG) Department of Public Works, Division of Sanitary Sewers evaluated treatment methods and corrosion rates present in force mains associated with three major pump stations. The evaluation consisted of improved chemical dosing, performance monitoring and corrosion coupon exposure to assess a corrosion rate for each associated force main.

Hydrogen sulfide control is critical in odor and corrosion control. Treatment systems utilized maintained average hydrogen sulfide vapor concentrations below 10 ppmv. Corrosion rates were measured in each system. The corrosion rate measurements were consistent within an order of magnitude and were within the boundary of corrosion rates expected.

LFUCG was able to validate an odor and corrosion control treatment method, and quantify a corrosion rate associated with the treatment method.
