chemical feed pump station to be housed in the existing RAS pump station # 1
with two (2) .5-8 gph peristaltic metering pumps capable of pumping sodium
hydroxide to both the primary clarifier and secondary clarifier effluent application
points, in conformity with the project plans, specifications, and other supporting
