Storm Manhole & Inlet Structures (Site Owner's Responsibility) 1. Inspect storm manhole structures, drywells and storm inlet structures and remove built-up vegetation, trash and debris - monthly (minimum) and after each storm event of 3-inches or greater. 2. Remove root intrusions and vegetation from structures and dry wells - as needed. 3. Repair broken castings and grates - as needed. 4. Inspect pipes located within the structures for signs of clogging or damage, repair as needed - annually (minimum). C. Underground Detention System (Site Owner's Responsibility) 1. Inspect underground detention systems annually for sedimentation and clean out sediment buildup. a. Locate the riser section of the retention/detention system. b. Remove the lid from the riser. c. Measure the sediment buildup at each riser and cleanout location. Only certified confined space entry personnel having appropriate equipment should be permitted to enter the detention system. d. Inspect each manifold, all laterals, and outlet pipes for sediment build up, obstructions, or other problems. Obstructions should be removed at this time. e. If measured sediment build up is between 5% - 20% of the pipe diameter, cleaning should be considered; if sediment build up exceeds 20%, cleaning should be performed at the earliest opportunity. A thorough cleaning of the system (manifolds and laterals) shall be performed by either manual methods or by a vacuum truck. GRAPHIC SCALE o ( IN FEET ) 1 inch = 20 ft.
