18 SW Cleaning Guidelines

Private Stormwater Cleaning Guidelines
Any release that enters waterways or the
town owned stormwater conveyance sys-
tem is a violation of Town Code Section 5-
32 and is subject to enforcement and fines.
Before cleaning any stormwater infra-
structure an inspection should be per-
formed to check for existing damage or
areas of concern that could be worsened
by cleaning activities. Perform any cor-
rective measures as needed.
Locate reaches of storm drain with de-
posit problems and develop a mainte-
nance schedule that keeps the pipes and
inlets clear of excessive buildup.
• Whenever possible, performed cleaning
activities from "top to bottom" (start up-
stream and finish downstream).
• Dry methods should be implemented
first, such as vacuuming and picking -up
trash using shovels or by hand. Confined
entry training may be required.

A,
Wet cleaning methods, including jetting
and flushing, should follow.
Vacuum any wastewater generated from
cleaning/jetting activities.
Flushed effluent shall be collected and
disposed of properly. Pumped to a sedi-
ment trap, or basin, or a detention pond
on site or removed from site and dis-
posed of at the appropriate facility.
Effluent shall not be permitted to enter
town owned conveyances, adjacent pri-
vate conveyances, or waterways. Use of
temporary plugs are recommended to
prevent effluent from leaving your sys-
tem.
Do not use any cleaning chemicals or
flocculants during cleaning activities.
Contact the Town of Carrboro Storm -
water Division to inform them of your
flushing activity 24 hours in advance.,
