[talk-ph] mapping water infrastructure in Leyte

Hello,

As part of the long term typhoon Haiyan recovery efforts in Leyte the Red
Cross has plans to map water access points (and also possibly other water
distribution infrastructure) in a few areas. The initial purpose is for
better planning of water and sanitation projects. Another goal being to
have the area better mapped for future disaster resilience and response.

I was wondering if people were aware of good tagging conventions used
elsewhere in the Philippines. The wiki page for Philippines mapping
conventions didn't seem to have anything. I was thinking...

## For access points:
+ amenity=water (all access points)
+ amenity=drinking_water (an additional amenity tag for points considered
potable)
+ man_made:water_well, pump=yes, pump:type=hand (for wells with a hand pump)
+ natural=spring (if water is actively flowing naturally from the ground at
the point)
+ access=yes (for public access)
+ I'm not sure about how to tag a public gripo/faucet/spigot connected to a
pipe network?

## For source points:
+ man_made=water_works (for the source of water being distributed through a
pipe network)
+ man_made=reservoir_covered, type=water (for covered water reservoir)

## For pipe network:
+ man_made=pipeline, substance=water
+ location=underground/overground (for buried pipes or pipes visible along
the ground)
+ Is it important to include diameter=* (diameter in millimeters) so that
there is no confusion between the small water pipes being mapped and the
larger pipes more commonly mapped with this tag?
+ Is there a key that could be used with values metal/pvc to give the
material the pipe is made from?

Comments and advice welcome. Salamat.
