People Need to Be Less Squeamish About Drinking Water Derived From Sewage?

It's clearly inefficient that UK Water companies, take the sewage from people's houses, (generally) treat it and then discharge the result into rivers and seas. The same Water companies, then take fluid from reservoirs, rivers and aquifers, process it and supply the result to people's household taps. The Head of the Environmental Agency thinks that part of the solution to UK droughts, is to change people's squeamishness (https://www.theguardian.com/environment/2022/aug/28/britons-need-to-be-less-squeamish-about-drinking-water-from-sewage-says-agency-head). The Environmental Agency's Head notes that water from sewage treatment, can easily be turned back into perfectly safe and healthy drinking water. He says, however, that many people wouldn't currently fancy it. Water is, however, simply H2O. The water cycle operates continuously. Most water molecules (even from reservoirs) will have passed recently through multiple kidneys before they reach the tap. If people would accept drinking water from treated sewage, much less water would have to be taken from other environmental sources. Rivers could continue to flow and aquifers would stay undepleted, even under drought conditions. Wild life would also benefit.
