Sad End

The ride to work every morning takes me onto the canal path right at the old Roxborough Pumping Station.  Well, before today it did.  Now it just takes me past the former site. 

This is what is looked like in 1903.

From the history of Philadelphia Watersheds:

By the end of the 1850s, it was already apparent to Henry P.M. Birkinbine, chief engineer of the Philadelphia Water Department, that the northwestern section of the city—including Roxborough, Manayunk, and Chestnut Hill—would need to be served by its own water works. The high ground in this area was far above the reach of existing reservoirs in the city, which supplied water by gravity to homes and businesses. Wells in populated areas were becoming unpalatable and in many cases unhealthy. A small private water works, built to serve Germantown and its vicinity, used a spring and dam of water along Papermill Run (now called Monoshone Creek), but Birkinbine predicted that its capacity would soon be outstripped by the rapidly growing population.

 
“Manayunk and Roxborough [contain] a population numbering about twelve thousand,” Birkinbine wrote in a report to City Councils in September 8, 1859. “Of these, at least three thousand are operatives employed in the different factories. This part of the city is much in need of a supply of water for culinary, manufacturing and sanitary purposes, and for protection against fire, as the property in the manufactories is of great value, and now almost entirely without protection against fire…. From the dense population of parts of the district, the wells have become so contaminated, that the water in but few of them is now fit for culinary purposes. The necessity of a supply for manufacturing and mechanical purposes, is evident.”

Birkinbine proposed a water works along the Schuylkill, with a pumping station above the Flat Rock Dam at Shawmont and reservoirs located higher up the steep banks of the river, which would provide water by gravity through distribution mains in the streets. This system would serve not only the immediate vicinity, but other areas of the city as well. Construction began on these works after the end of the Civil War, with the pumping station at Shawmont completed in 1869. The steam-powered pumps force water uphill into a reservoir (about 366 feet above city datum) located at present-day Eva and Dearnley Streets in Roxborough. To increase the capacity of the Roxborough Works and allow water to flow by gravity to a larger part of the city, the pumping station on the Schuylkill was expanded in the 1890s, and a much larger reservoir was built higher up the ridge (the Upper Reservoir, about 414 feet above city datum), along Port Royal Avenue about a block from Ridge Avenue. 
 
In the first decade of the 20th century, the city spent more than $30 million to construct slow sand filter plants around the city. Two of these plants were at the Lower and Upper Roxborough Reservoirs. Once it went into operation citywide in 1909, the filtration system greatly reduced the incidence of water-borne diseases such as typhoid fever, which had been transmitted by the untreated (and sometimes sewage-tainted) river water.

I only hope that they will at least leave the short stretch of cobbles that links the road to the old canal path.


I will resist writing a long diatribe on how we undervalue our history and fail to blah blah blah... Suffice it to say it is a sad end to a magnificent piece of engineering and history.  If you've got more time to kill, there is some very cool info at this site.
