Collinsville water treatment plant
Hurst-Rosche Engineers provided a preliminary design assessment of a previous preliminary engineering report prepared by another firm. Hurst-Rosche assisted the City with a subsequent structural evaluation and cost analysis of the existing WTP building and structures in which it was determined that it was not economically feasible to rehabilitate the existing structures. Hurst-Rosche was retained by the City of Collinsville to proceed with the design of a new 5.0 MGD Water Treatment Plant. The new WTP will consist of a new head tank and aerator; two 47’ diameter claricones; four 21’ diameter decelerating filters; a new clearwell and high service pump facilities; and new chemical feed systems for their chlorine, fluoride, lime, alum and carbon dioxide.
