• Advanced water treatment
• Management of advanced treated water in a drinking water
system
• Process monitoring
• Residuals management including brine disposal
• Facility operation
• Public outreach
• Future developments.
Paramount among these topics is the implementation
of a multi-barrier approach to removing pathogens and
chemical constituents. These barriers can include management
barriers such as pretreatment policies and proper operations
and maintenance procedures, operational barriers such as
monitoring and response plans, and the technical barriers of
the physical treatment processes. When taken together, these
barriers form the foundation of a robust and resilient DPR
system.
Mapping The Complete DPR Process
A primary theme of the framework document is that DPR does
not include just the treatment processes associated with an
advanced treatment facility but also source control programs,
traditional wastewater treatment, and the integration of
advanced treated water into a drinking water treatment facility.
Understanding that the performance of upstream processes can
have an effect on downstream processes can go a long way to
ensuring that a DPR system is performing properly.
A properly implemented source control program can help
eliminate the discharge of constituents into wastewater that
can be difficult to treat or impair the final quality of secondary
effluent intended for DPR. This can be especially important in
communities with large commercial and industrial discharges.
There are several important elements to a source control
program, including the legal authority to develop source
