Thanks for asking. I suggest ceasing rocket and mortar fire and other violence, rewriting charter to eliminate the hostile language, releasing Shalit, recognizing formally the Jewish State of Israel, reconciling with Fatah, negotiating with Israel for boundaries of state within about 90% of WB, giving up demands for RoR and J'lem capital. All those are political. I would also introduce the concept of birth control in Gaza, whose population right now far exceeds the ability of the aquifer to support, yet the birth rate is the highest in the world. With all these in place, fixing the sewage problem would be easy. The entire world would help.
