CATCH BASIN INSPECTION ROUTE PROCEDURES
PURPOSE
Regular maintenance of catch basin and inlets is necessary to ensure their proper
functioning. It is important to remove sediment and debris from catch basins, including
the surface grate and the interior of the catch basin. Catch basin maintenance prevents
storm sewer blockages and minimizes the amount of pollutants entering the storm sewer
which eventually discharges into our streams and waterways. Clogged catch basins are not
only useless but may act as a source of sediments and pollutants. Clogged catch basins can
also result in the ponding of water along street and parking lots causing a nuisance to
motorists, pedestrians and businesses.
ROUTE DESCRIPTION
The catch basin inspection route divides the city into three primary quadrants. Area I is
located on the west side of US 74, and is bounded on the north by Dickerson Boulevard
and on the south by Skyway Drive/Hayne Street. Area II is on the west side of US 74,
south of Skyway Drive/Hayne Street. Area III is located on the east side of US 74, south
of Secrest Shortcut Road; the east side of US 74, north of Secrest Shortcut Road; and
includes remotely annexed areas that are not included in the other areas. To keep our route
current, the maps and routes should be updated annually in January.
While running the catch basin route, every street in the City will be checked. This is a
great opportunity to observe and note other issues that Engineering or Street Division
handles.
Therefore, during and after a rainfall event, the following procedures shall be followed by
each crew completing their assigned catch basin route.
PROCEDURE
I) Each crew should physically inspect every catch basin for problems within their
route:
1. The crew should remove any debris found on and in the catch basin, gloves
should be worn at all times;
2. All catch basins will be checked and cleaned on state roads within the City
except US 74 and US 601 N. Any problems with these catch basins will be
reported to the Streets Superintendent or Stormwater Engineer for review;
3. All cross drains within the municipal right-of-way will be checked for any
debris and/or blockage. Any debris and/or blockage will be removed;

4. When cleaning cross drains, always use caution when water is flowing at a
high rate;
5. Report findings to the Streets Superintendent.
II) Hand tools should be used for smaller amounts of debris with gloves worn at
all times, while a vacuum truck should be used where there is an extensive
amount of debris.
III) Check that all the catch basins along the route are in the inventory. If a catch
basin or cross drain is not in the inventory, note the location of the catch basin
and report the finding to the Engineering and Stormwater office staff.
IV) While running the route, use the time to observe and identify the following:
1. Are there any roadway failures that need immediate or scheduled repair?
2. Are there any road shoulders that need to be clipped?
3. Are there faded or damaged road signs?
4. Are there any repairs needed to the drainage system?
5. Is there any sidewalk that needs repairing?
6. Does the sidewalk or curb line need to be sprayed for weeds?
7. Is there any curb and gutter that needs repairing?
8. Are there any sight obstructions?
If any problems are observed on City maintained roads, submit your findings to the Streets
Superintendent. The Superintendent and Crew Leaders are responsible for inputting the
information into HTE Work Order System for future tracking. If there are any problems
observed on NC DOT maintained roads, the Streets Superintendent shall contact them by
email or phone to relay the concern.
Procedures for disposing of collected debris from catch basins:
1. The date and total estimated quantity of collected materials for that day should
be recorded;
2. Properly dispose all materials at the landfill.
