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!
