Singapore has also gone out of the way to change the paradigm by referring to wastewater as “used water”.

A recent visit to Denmark made me realise that the global challenge of pharmaceuticals and personal care products (PPCPs) in wastewater was even more onerous than I thought.

Most hospitals are discharging their wastewater to municipal treatment plants, which as insiders know too well, are woefully inadequate to deal with PPCPs. Continue reading
