Benjamin Schachtman The Cape Fear Public Utility Authority is delaying a pilot program to restrict water flow to residential customers with delinquent accounts. CFPUA is one of the first in the nation to consider this type of program and, while it’s based on a very simple piece of technology, the issue driving it is much more complicated. --- In the fall, CFPUA first announced a pilot program that would experiment with flow restrictors --- a quarter-shaped device with a small hole in the center that reduces water flow by roughly 90 percent or more. The reduced flow means filling a glass of water would take about 12 seconds, and taking a shower or running a washing machine would be difficult, although not impossible.
