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

[Erwin Olario]

I'm glad you made it to the mapa-thon [0], Eugene.

Over the weekend, in San Juan, we had another mapa-thon and one of the
things we did different were "Blitz Decks" (a.k.a. lightning talks) during
the break. Many thanks to Rally and Dianne, for their decks about mapping
addresses and UP Noah (aka Project Noah), respectively. Mine was called
"Hail Hydra(nt)!"

I thoroughly enjoyed the after hours conversation that was triggered by the
Blitz Deck. I'd like to see more varied topics for in future mapa-thons!

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

[Eugene Alvin Villar]

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!

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

[Wayne Manuel]

Yes. I noticed it three years ago and have wondered about it since then.
I've even imagined building an expressway over it in my mind's version of
Metro Manila.

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

[Eugene Alvin Villar]

More research confirming the water pipeline theory:

-

1) http://www.lawphil.net/judjuris/juri2000/jun2000/gr_109111_2000.html

Quote: "Long before World War II, MWSS buried a 42-inch diameter steel
aqueduct pipeline under the subject parcels of land. The pipeline drew
water from the Wawa Dam in Montalban, Rizal to the Balara Filters in
Quezon City. Fifteen (15) kilometers long, it ran through the
municipalities of Montalban, San Mateo and Marikina."

The MWSS property in Balara  does indeed
lie close to the "line".

-

2) http://inquiry.theguidon.com/2009/08/service-for-the-settlers/

Quote: "Daan Tubo and Ronas Garden are owned by Manila Water Services
and Meralco, respectively."

Daan Tubo in this case is the informal settler area along Katipunan
beside UP Diliman .

-

Mystery closed?

I must say that I find it amazing that this unused pipeline still
shows it's presence even to this day in the form of roads, barangay
boundaries, and informal settlers. :-D

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

[Eugene Alvin Villar]

I was editing in Diliman yesterday when I noticed that the linear
boundary between UP Diliman and Loyola Heights and Pansol[1]
apparently went further northeast and southwest than I thought. If you
go northeast you'll notice that the southeast perimeter of Ayala
Heights[2] follows the same line. If you go further northeast, other
residential subdivisions follow the same line[3]. Go further northeast
into Rizal and there's a parallel road that follows the same angle[4],
which in Google Maps is named "Daan Tubo". So this is a pipeline?

Interestingly, the footway from Katipunan running along UP Diliman is
also called "Daan Tubo"[5]. I don't think it's a coincidence that
these two ways kilometers apart are named the same thing.

If you go the opposite direction, it seems that the barangay
boundaries between East Kamias and the Quirinos follow the same line
and ends near Cubao[6].

But, if you switch to satellite imagery, such as in Brgy. E. Rodriguez
in Google[7], you can see the same line via the house lots! You can
follow the same line all the way into San Juan where it disappears[8].

Is this a real pipeline, possibly abandoned?

I have 2 theories.

1) This is an oil pipeline. If you follow the line into Manila, it
goes close to the Pandacan oil depot. But why would it go to Rizal?

2) This is a water pipeline. The line's end in the northeast is
somewhat close to Wawa Dam and this dam used to supply Metro Manila's
water before the Angat-La Mesa dam system became operational. In
addition, the line passes right next to the MWSS reservior at San
Juan[9]. I have a hunch that this is the correct answer.

What do you guys think? :-)

Here's a overview map of this line:
