Toilet to tap: Would you drink recycled water?
Let’s face it, we all feel a little bit icky when we think about toilet water generally. Then, if we are asked to think about transforming wastewater into drinking water – our stomachs are likely to respond with an indignant flip of protest. As much as the brain may try to reason, our natural impulses are stubborn – so while there is a weight of evidence and assurances that modern treatment technologies can create perfectly safe and pure water, there is an unavoidable psychological aversion to drinking water which has already been ‘used’. The reality is, we need to start coming to terms with alternative drinking water supplies as a very real opportunity to create efficient and sustainable water supplies for our cities.
