[talk-ph] Geo mystery: What is this weird northeast line running from San Juan to Montalban?

Hi all,

I'm resurrecting this old thread[0] because we've been discussing Metro
Manila's water system as part of the fire hydrant mapping exercise during
the mapathon earlier.[1] It turns out that before we have the current San
Juan Reservoir,[2] there was an older Spanish-era reservoir named El
Deposito located in what is now the Pinaglabanan Shrine in San Juan. This
is apparently where the long straight pipeline from Montalban terminated.
You can read a bit of the history of El Deposito on Wikipedia[3] and on the
historical marker installed by the National Historical Commission of the
Philippines.[4] The El Deposito is also roughly in the middle of the
straight line connecting the Santolan Waterworks in Pasig and Intramuros.

You can now see these two lines, one Spanish-era, and the other
American-era, on a map created by Erwin.[5] As you can see, these two lines
converge at El Deposito!

This is really fascinating!
