Decatur Utilities owns and operates a potable water treatment and distribution system for the northeast Alabama port city of Decatur. The water supply for Decatur is the Tennessee River. The water treatment facility is a 68-mgd conventional plant that includes coagulation, settling, filtration, and disinfection.
Constantine Engineering was selected by Decatur Utilities to evaluate the water plant and identify capital improvements to restore capacity, increase efficiency and improve the reliability of treatment. Constantine developed priorities that included improvements to raw water pumping, chemical feed, flocculation, filtration, telemetry controls, and a new emergency power generator.
Constantine also assisted Decatur Utilities to secure financing from the Alabama State Revolving Fund (SRF) to design and build the improvements to the water system. Because of energy savings from the proposed technology improvements, the SRF funds were matched with principle forgiveness funds from the American Recovery and Reinvestment Act. Constantine Engineering provided design engineering services, construction management, onsite construction observation, and SRF administration.
