Cecilton Water Treatment Plant
Project Description
Carew Associates coordinated the design of the electrical power distribution system and controls system with the proposed facility design by URS Corporation. Our company also performed heating and ventilation design for this project.
The electrical power distribution system included a 480-volt 3-phase 200-amp service and a 100 kW standby power generation system with an automatic transfer switch. The generator is capable of carrying the entire plant load in the event of a power outage. Transient Voltage Surge Suppression was included to protect equipment from electrical transients caused by lightning and other disturbances.
The Well System Control Panel design included a programmable logic controller or PLC, and a small panel mounted Human Machine Interface. The design included a connection diagram for the PLC inputs and outputs. Connections between the PLC and a cellular-telephone-based Remote Telemetry Unit (RTU) included alarms (trouble, shutdown, building intrusion, smoke alarm, generator trouble, and station on generator power), tank level, and pump running status for both well pumps. The information from the RTU is accessible through an internet web site, helping the owner to track pump operational details and current level in the water storage tank.
