MAINTENANCE
COMPONENT
DEFECT OR
PROBLEM
CONDITIONS WHEN
MAINTENANCE IS NEEDED
RESULTS EXPECTED
WHEN MAINTENANCE IS
PERFORMED
Preventive Blocking,
obstructions
Debris or trash limiting flow
into perforated pipe system or
outfall of BMP is plugged or
otherwise nonfunctioning.
Outfall of BMP is
receiving designed flows
from perforated pipe
connection.
Inflow Inflow impeded Inflow into the perforated pipe
is partially or fully blocked or
altered to prevent flow from
getting into the pipe.
Inflow to the perforated
pipe is unimpeded.
Pipe Trench Area Surface compacted Ground surface over the
perforated pipe trench is
compacted or covered with
impermeable material.
Ground surface over the
perforated pipe is not
compacted and free of
any impervious cover.
Outflow Outflow impeded Outflow from the perforated
pipe into the public drainage
system is blocked.
Outflow to the public
drainage system is
unimpeded.
Outfall Area Erosion or
landslides
Existence of the perforated
pipe is causing or
exasperating erosion or
landslides.
Perforated pipe system
is sealed off and an
alternative BMP is
implemented.
