#3 Pumping Engine, New Milford Plant of the Hackensack Water Works, 2009. Less than a decade after a huge addition had to be made to the engine house at this water works facility in Oradell, NJ, technology had evolved. That addition - built to hold the 5-story-tall “Old #7″ Allis-Chalmers VTE pumping engine - was enormous, and the engine it was built around could pump 20 million gallons per day (MGD). Just 8 years later, this room was added on - a fraction of the size - to hold the engine pictured here. It is an Allis-Chalmers Centrifugal Engine, built for a fraction of the cost - but capable of pumping 30 MGD! Allis-Chalmers was the undisputed king of water distribution in the early part of the 20th century; the fact that this plant has two well-preserved examples of their groundbreaking technology makes it a site well worth a visit!
