Q. 2.6 - October CAC meeting - What’s the benefit of doing FDDs, if you can get the same stormwater reduction result from fixing the pipes? Or if pipes are deteriorating at a rate to offset any reductions from FDDs?

A. It is not clear that the same flow removals can be achieved by rehabilitation of the pipes. The analysis of effectiveness of the FDD program on flow removals will identify how much flow was removed from FDD’s and how much remains from other sewer defects in the five priority areas. This information can then be used to answer this question, and assess the feasibility of non-FDD flow removal in the future.
