Higher contaminant levels in the feed water require direct potable reuse facilities to maintain rigorous health and safety protocols. Hazen and Sawyer is working with the WateReuse Research Foundation to adapt the Hazard Analysis and Critical Control Point methodology to direct potable reuse (DPR) treatment and operations. First developed by NASA for the Pillsbury Company in the 1960s, the methodology has proven itself in the food and beverage industry.

Once the treatment system is established, operators constantly monitor the performance of the system’s Critical Control Points (CCP), following tested and proven response protocols to maintain protection of public health.

This infographic illustrates the process of identifying CCP and implementing appropriate operational responses.
