LCFWASA LCFWASA pumps untreated water from just north of Lock and Dam No. 1 on the Cape Fear River in Riegelwood, all the way down to the Sweeney Water Treatment Plant, north of the Isabel Holmes bridge in Wilmington. Water travels through a 48-inch pipeline that stretches 24 miles and crosses the river twice. Crews are working to install a second, 54-inch parallel pipeline that traverses the same path. Once online, the $37 million project will immediately increase LCFWASA’s delivery output, from 45 millions of gallons a day (mgd) — the current max — to an estimated 62 mgd, without additional improvements necessary. It will also provide redundancy that will protect the system against catastrophe: In 2016 during Hurricane Matthew, the pipe ruptured, losing 12.5 mgd over a two-week period.
