This AwwaRF project focused on developing distribution system water quality
optimization plans (DSOPs).
System optimization is defined here as a process that water utilities undergo to improve
distribution system operations above and beyond regulatory requirements to improve water
quality and reduce the potential for contamination.
The project had two main objectives:
to develop specific DSOPs for three participating utilities; and, to develop a DSOP template or outline applicable to utilities of any size.
The first project objective was completed by conducting an audit and field investigations
of the conditions and operating status of each of three distribution systems. The audits were used
to identify strong points as well as areas that needed to be improved to meet industry standards
for distribution systems. Water quality and operating goals were established and documented for
each system. These goals were used to determine which programs the participating utilities
would focus on for their DSOP. Individual distribution system programs were then developed at
each utility and these elements were field-tested and refined at each utility location.
Based on the utility experiences and the project team's experience and knowledge, a
template of best management practices was developed as well as a general outline and approach
to implementing DSOPs. Includes 41 references, tables.
