Project Overview

Millstone Weber (MW) was awarded the DeSoto Yard Treatment System Project in Spring 2016 to construct a new treatment pond responsible for capturing and treating stormwater from Union Pacific Railroad’s (UPRR) DeSoto Yard. The project was built in conjunction with MW’s DeSoto Yard Expansion Project, and included the excavation of existing soils and replacement with imported low-permeability clays for construction of treatment pond berms and bottom. MW installed two prefabricated water treatment units, one cast-in-place concrete overflow chamber, one precast concrete pump station, and one precast energy dissipation structure to complete the system. All work associated with both contracts was completed by the strict deadline for operability of the new treatment system of June 1, 2017.
