CMT has been providing potable water system planning, design, and construction engineering services for the city for over 40 years. Their work has included municipal raw water wells and associated wellhouses, the river intake, well collector mains, the water treatment plant, finished water transmission mains, various booster/pump stations, and storage tanks. CMT most recently completed an update of the hydraulic model of the potable water distribution system in 2017.
