Q. Recent
conversations with OHM indicate prelim info that some neighborhoods are showing
greater footing drain flow than others. One idea is that some areas have homes
with only one set of footing drains, (i.e.: exterior or interior of the
footing, but not both). Can the approved contractors be contacted to provide
their observations during the actual FDD installations?
A. CDM has investigated the occurrence of “bleeder type”
footing drains in the various priority FDD areas based on their work on the FDD
program. The have found the following:
· Approximately 55% of the houses in Glen Leven
have “bleeder type” footing drains
· Approximately 5% of the houses in Dartmoor have
“bleeder type” footing drains
· None of the houses in Orchard Hills, Bromley and
Moorhead have “bleeder type” footing drains
The sump pump monitoring data that CDM collects was
evaluated to see if the high occurrence of “bleeder type” footing drains may
have an impact on the sump pump flows measured, and no difference was observed
in the data. An analysis of statistical significance was not performed on this
conclusion, but the results suggest that differences in the FDD flows are
likely from other impacts besides “bleeder type” footing drains.
