Elaborate sustainable water supply systems, efficient zero waste architecture.

精心设计可持续供水系统，高效的零废物架构。

A sustained power outage might lead to a breakdown of the supply chain; water supply systems failing and hospital generators running dry; Supermarkets not being refilled, while food rots in the fields.

持续的停电可能导致供应链崩溃；水供应系统垮了，医院的输液瓶干了，超市的商品没有被重新放入，食物也在农田里腐烂。

While politically and environmentally controversial would obviously go a long way to reducing Cape Town's risk of a single point of critical failure in their water supply system if the rain stops falling for years at a time again.

虽然在政治上和环境上有争议，但显然会大大减少开普敦的风险，如果再次停止降雨多年，他们的供水系统就会出现严重的关键故障点。
