Hydrologic border suture

Two mayors, one in a Palestinian town, the other in an Israeli town, have agreed to a joint venture to clean up the polluted river that runs between them.

Israel holds all the power in the water wars there, and can pump water from the aquifers at any time while Palestinians must beg for permission. Both have been known to sabotage the system so that cascades of sewage pour onto to others land.

Perhaps this joint venture can lead to other agreements on other issues.
