Rosenwach Tank Has Stayed In Business For 150 Years Doing Something That's Almost Obsolete


Six workers are swinging axes, hauling timber and throwing around an arsenal of power tools perched high above an old building on Harlem's 125th Street.


With no scaffolding or supports, they're a rare sight. Even more unusual: they're building a wooden water tank.


This is the legendary construction team of Rosenwach Tank. They can put up a 10,000-gallon wooden water tank in less than half a day. 


You’ve seen their work.
