Access to drinking water and sanitation are among the goals adopted by the United Nations in its 2030 Agenda for Sustainable Development. However, in poor and low‐income countries, this goal has not yet been reached. This is caused by several lacks in the technological mastery of water and wastewater treatment processes, fresh water and sanitation networks, and, finally, financial resources. Increasing the success chances to reach this goal should not happen by copying centralized water and sanitation systems used in high‐income countries. Rather efforts need to be made towards energy‐efficient decentralized water and wastewater treatment facilities, using simple and sustainable low‐cost technologies.

通过太阳能废水处理（SOWAT）适应气候变化，可在农业和工业中重复使用*

获得饮用水和卫生设施是联合国在其《2030年可持续发展议程》中通过的目标之一。但是，在贫穷和低收入国家，这一目标尚未实现。这是由于缺乏对水和废水处理过程的技术掌握，淡水和卫生网络以及最终缺乏财务资源造成的。通过复制高收入国家/地区使用的集中式供水和卫生系统，不应增加实现这一目标的成功机会。相反，需要使用简单且可持续的低成本技术，为节能的分散式水和废水处理设施做出努力。
