Statement of Work Replacement of Dual Rapid Sand/Mixed Filter Media At Water Treatment Plant Bureau of Indian Affairs, RMR Crow Agency Crow Agency, Montana

BACKGROUND

The Bureau of Indian Affairs (BIA), Water Treatment Plant has two mixed media filters that were built and put into production in 1965. The top portion of media was replaced in 2011 but the bottom half and more importantly the under drain have not been exposed nor worked on since the manufacture date (1965). Due to this unforeseen maintenance, the production rate of the water treatment plant has been restrained. After calculation and testing, our present-day filtration rate in one filter is 1.26 gpm/Ft2. With both filters running, the highest volume produced is 150 gpm compared to the manufacture rated 535 gpm.

OBJECTIVES

The objective of this Statement of Work (SOW) is to define and establish a general scope of services necessary for the two mixed media filters removal, repair, and installation.
