"Gaza’s power plant shut down entirely in April this year, and Israel further reduced electricity supply to Gaza this week – a violation of international humanitarian law, according to human rights groups. Electricity is currently available fewer than three hours per day.
One of the results – among others profoundly affecting daily life in Gaza – is that there is not enough power to run sewage treatment facilities in the territory. Desalination plants, which provide most of Gaza’s drinking water, are also operating at significantly reduced capacity."
