Pumping station disguised as plain old house

In a residential neighborhood in Raleigh, North Carolina, there's a house that looks like most every other house on the block. But it isn't a house. It's a public utility pump station perfectly camouflaged as a house. The inside is filled with massive industrial pumps chugging away. WUNC made a video documentary about the place. Apparently, this is a fairly common way to build electrical generators, pump stations, and other utility infrastructure in residential areas. That quiet house down the street from you? The one where nobody seems to live? Who knows what machinery resides inside… "What's Inside This House On Wade Avenue?"
