Mallard Creek WRF and Lee S. Dukes WTP Standby Power and Electrical Improvements

This $16.2 million project included standby power and electrical improvements at two of Charlotte Water’s treatment sites. The Mallard Creek WRF work included a new standby generator facility, conversion of the existing utility service from 480V to 4160V, electrical upgrades to the existing blower building and the replacement of an existing electrical switchboard. The Lee S. Dukes WTP improvements included a new standby generator facility and the replacement of the existing 4kV switchgear and 4kV electrical duct bank to re-feed the existing transformers.

The improvements at the two facilities, which are located 18 miles apart, provide high-level electrical performance and reliable emergency power systems.
