Wish I had a chance to meet the reporter to show him that rainwater is and can be harvested in Sanaa city and not just in agricultural areas.
An interesting large rooftop rainwater harvesting site can be found at Bilquis Club for Women in Sanaa, Yemen. The site could be even larger than it is currently because the club's facilities are part of a large park dedicated to families. Half of the park floods during a heavy rain like what happened this past week in Sanaa. The flooding is magnified by water that is channeled into the park from a main street in Sanaa. Meanwhile the park has four wells, two of which have run dry. One of the two is nearly 1000 meters down and is actually a bore hole.
However, ensuring this park really is family friendly and returning things to way they were (simply put: getting the water back into the ground - groundwater recharge) will require some commitment by folks to realize the vast amounts of water that could be more properly channeled.
I had once heard that a former leader of Yemen had divided the city into areas that would be serviced by parks, centers and schools - all walkable. That type of urban planning unfortunately did not happen. The lack of planning ensures that there will be much of the city needlessly under water that could be channeled elsewhere.
