Challenges to implementing DPR
There are already several indirect potable reuse – or IPR – facilities reclaiming water in the US and around the world. IPR uses an almost identical treatment process to DPR but for the addition of an environmental buffer, such as a lake, reservoir or groundwater aquifer, where the water sits after a first round of treatment and is diluted with a raw water supply. The water is then treated again before it is distributed to the public.
