St. Michaels Water System Improvements – Marengo & Glory WTPs

Johnston Construction Company

• Served as Prime Contractor directly to the Town of St. Michaels for comprehensive water-system improvements at the Town's two existing water treatment plants serving Marengo Street Well No. 2 and Glory Avenue Well No. 3.
• Delivered a multidisciplinary water-treatment upgrade encompassing process piping, chemical-feed systems, masonry-building construction, electrical controls and equipment, instrumentation, treatment equipment and site improvements.
• Executed the work through a carefully phased construction sequence to maintain the Town's drinking-water supply. At the start of construction, the Marengo WTP was idle and the Glory WTP was providing the Town's full water supply; Glory was required to remain continuously operational until the Marengo improvements were completed and placed into service.
• Completed initial erosion and sediment-control work followed by construction of new treatment tanks, piping and process equipment at the Marengo WTP.
• Coordinated improvements at the active Glory WTP that could be completed without interrupting treatment, then placed the renovated Marengo facility into service before completing the remaining Glory WTP improvements.
