It's just that... a coincidence.
That post on Facebook was related to the ongoing construction work related to the expansion of the Sweeney plant, which was started in August 2008 and will be finished in 2012.
This project was approved under the aegis of the City of Wilmington, before CFPUA was formed.
The statement was to inform the public that the current construction, which involves tie-ins of several different sizes of pipe, may cause capacity to be reduced, due to the fact that when you tie in pipe (which is anywhere between 24 inches or more, depending) you have to temporarily turn off water distribution.
Also, the system of underground pipes under Sweeney is huge and a lot of it dates back to the 1800s and it is scheduled to be replaced, so stuff like this can happen.
