Short video on NYC's water supply system

The YouTube video above provides a short (but comprehensive) overview of NYC's water supply system; where it comes from, how it's distributed, how a majority of the water is unfiltered and what steps PlaNYC is taking to protect its water supply from contamination. Despite NYC's water abundance, it's important to keep in mind that conservation initiatives (public education and water metering) should be critical components of its planning process and vision.

It would great to see other videos on other cities' water supply systems such as the one above. I would personally like to see one of Vancouver and Toronto. Short videos like these can go a long way in building awareness of a city's water system and the programs, risks and policies that should be known by residents.
