Weston & Sampson pianned and designed a complete Controls and SCADA
Upgrade for the Town of Salisbury Water System. Prior to the upgrade, operators
lost sleep during every storm worried that controls would fail or they would have
to rob one panel of components to fix a more critical one. Our design included
replacement of obsolete controllers, out-of-cornpliance radios, and aged SCADA
software and PC.
