I chose these three: 1- drinking water in here is transported to houses and residential buildings by trucks, but I believe there is better way to transport it, and that is by create an underground pipeline network to avoid higher transportation costs. 2- all gas stations in here usedto refill their gasoline tanks by trucks that come to the stations every few days, and I think just like the first examle that creating an underground pipeline network to transport gasoline to the stations might be less costly and effortless in the long run. 3- There is a huge number of illegal foreign workers in Saudi Arabia, especially handymen, and I see them setting every day on sidewalks waiting for any one to hire them for daily payment work, and this problem needs to be solved.
