City of Meridan, Connecticute Saves Time and Money With new Control Systems

Proving high quality drinking water for a city of 59,000 people is a challenge in itself.  Retrofitting the controls and instrumentation for six water treatment plants and 13 remote stations, and tying them all together is an even greater challenge.  The City of Meriden, Connecticut, Water Division, was facing this task in April 2001.

• The water plats and remote stations had limited monitorig and and control capabiities. 
• The newer treatment faciities used motor control centers or analog controls, while older treatment plants, remote pump stations, storage tanks, and metering facilities were manually controlled. 
• Operators had to drive to a facility to solve problems. 
• Effluent water quality data from the filters and water usage data had to be collected at each individual plant. 
• Record keeping and daily, weekly, monthly, and yearly reports were prepared manually.
