Water? What Water? Monthly Theme Day

You might think we're trying to play an April Fool's joke -- this month's theme is "Water" and we're giving you "Sand."

Truth is, the sand dunes that separate Wassenaar from the North Sea couldn't be more important to the area's residents as far as water is concerned.

The dunes naturally filter water, which becomes the water supply for 1.2 million customers. The natural filtration means that the water undergoes minimal processing before it's distributed.

The local water authority (Duinwaterbedrijf Zuid Holland) is also responsible for the conservation of the dunes.

As often happens with theme days, the "water" theme will inspire posts for some time to come, so check back often.

There are currently 178 (!!!) blogs signed up to participate in April's "Water" Theme Day:
