eMJA: Water recycling — forwards or backwards for public health?

To the Editor: Recycling water from sewage into drinking water was recently discussed in the Journal.1 Although this is technically feasible, we need to be very wary. Such recycling is associated with very high ongoing monetary and energy costs, but, most importantly from a health perspective, is a “very high-risk”2 proposal that reverses 150 years of good public health policy of striving to keep sewage out of our drinking water supplies.
