Stormwater Maintenance
Mark your calendars. It's time for cleaning.
On your mark. Get Set. Go. It's time for maintenance! So break out your list of stormwater controls, maintenance schedules, and inspection forms, find a pen, pencil, or computer, and let's start prioritizing and cleaning!
Now is the time to consider developing an operation and maintenance (O&M) plan or manual if you don’t already have one. O&M plans may include basic elements such as:
- Identification of the parties responsible for maintenance
- Maintenance schedules
- Inspection requirements
- Frequency of inspections
- Easements or covenants for maintenance
- Identification of a funding source
- Description of basic maintenance activities like weeding, mulching, trimming of shrubs and trees, replanting, sediment and debris removal, and inlet/outlet cleaning

Maintenance Descriptions and EPA Resources
- Catch Basin Inserts
Typical maintenance of catch basins includes trash removal if a screen or other debris capturing device is used, and removal of sediment using a vactor truck. Operators need to be properly trained in catch basin maintenance. Maintenance should include keeping a log of the amount of sediment collected and the date of removal. Some cities have incorporated the use of GIS systems to track sediment collection and to optimize future catch basin cleaning efforts.
- Green Infrastructure Maintenance
Maintenance of green infrastructure generally requires more labor and less heavy equipment than maintenance of gray infrastructure. Learn about what to look for when you inspect green infrastructure and how frequently to conduct maintenance activities.
- Wet Ponds and Wetlands
Wet ponds and wetlands assist communities in developing an integrated stormwater management systems which includes proper maintenance of existing wet ponds and wetlands, the exploration of retrofit opportunities, and implementation of micro-treatment practices and design principles.
State Best Management Practice Manuals and Maintenance Information
Many state manuals have information on best management practices, maintenance schedules, and various checklists that can be used when performing maintenance. Some of these resources are listed below.
