CSO Disinfection Workshop—Response Summary
Weighing the risks and benefits
of wet-weather disinfection
Presented at
The Rosamond Gifford Zoo, Syracuse, NY
October 15, 2002
On October 15, 2002, Onondaga County conducted a half-day
workshop entitled “CSO Disinfection.” A list of
attendees that signed-in is includd in the appendix of
the attached responsiveness summary.
There is no formal stenographic record from the
workshop. However, we have prepared a summary
proceedings. Presentations are in brief bullet form.
Questions and answers are paraphrased—not exact
quotes. Also, in many cases, we have added additional
clarification to answers to provide a more complete
resource on the topic.
Excerpt from the workshop
Use of chlorination-dechlorination has proven to be
more commercially advanced, more reliable and more
cost-effective than the alternatives. Given the highly
variable flows and influent strengths,
chlorination-dechlorination is the preferred
technology at this time. This technology does not
preclude implementing a different technology when one
becomes more feasible.
