Site work for a water / sewer project in Arkansas City, Kansas. Completed plans call for site work for a water / sewer project.

SCOPE OF REQUEST a. The scope of the project includes the design and construction of improvements to the city's existing water treatment plant. The expansion will address the presence of manganese in the raw water supply. Iron and manganese treatment will be accomplished with Greensand pressure filters. The city's well field is classified as alluvial groundwater adjacent to the Arkansas River. The improvements generally consist of the addition of one Greensand pressure filter, piping, and controls. The equipment will be installed within the space allocated in the original design. The City's existing reverse osmosis WTP has a capacity of 5.4 MGD. The addition of Greensand pressure filters will enable the city to treat and remove manganese from its alluvial groundwater supply more effectively. Manganese is under increased scrutiny by the EPA and KDHE due to updated health effects information and additional occurrence data. The prevailing thought is that manganese will become a primary water quality standard; therefore, the treatment technology selected will provide water with manganese levels <0.05mg/L.
