Common Stormwater System Maintenance Tasks
Posted on: 21 July 2023
Stormwater systems play a crucial role in urban environments, managing rainwater runoff to prevent flooding and protect water quality. Given their importance, regular maintenance is essential to ensure these systems function optimally. Here are some common tasks involved in maintaining a stormwater system.
Cleaning Catch Basins and Inlets
Catch basins and inlets are the entry points into the stormwater system, collecting runoff from streets and surfaces. They often trap debris such as leaves, trash, and sediment, which can lead to blockages if not regularly removed.
Routine cleaning is necessary to keep these components functioning properly, typically involving manual removal of accumulated debris or the use of vacuum trucks for larger systems.
Inspecting and Cleaning Pipes
The network of pipes in a stormwater system can also become clogged with debris or sediment. Regular inspections, either visually or using specialized cameras, can identify any blockages or structural issues, such as cracks or misalignments.
Depending on the problem, jetting, rodding, or other cleaning techniques can be used to clear the pipes, while more significant issues may require repair or replacement.
Maintaining Stormwater Ponds and Detention Basins
Stormwater ponds and detention basins are designed to hold and slowly release stormwater, helping to manage flow and improve water quality.
Maintenance tasks for these structures can include removing accumulated sediment, managing vegetation growth, repairing eroded areas, and ensuring outlet structures are clear and functioning correctly.
Inspecting and Cleaning Stormwater Controls
Many stormwater systems incorporate controls, or best management practices (BMPs), designed to improve water quality or manage flow. These can include bio-retention areas, swales, permeable pavements, and green roofs.
System controls can call for various maintenance tasks, such as replenishing mulch in bio-retention areas, ensuring swales are clear and properly graded, or managing vegetation on green roofs.
Repairing Structural Damage
Over time, components of the stormwater system may suffer structural damage due to wear and tear, heavy flows, or ground movement. This can include damaged catch basins or inlet grates, cracked pipes, or eroded detention basins. Identifying and repairing such damage is crucial to maintaining the system's integrity and function.
Monitoring System Performance
Monitoring the performance of the stormwater system can help identify potential issues before they become significant problems. This can involve tracking flow rates during rain events, analyzing water quality exiting the system, or regularly inspecting system components following heavy rain.
Regulatory Compliance and Record Keeping
An often-overlooked aspect of stormwater system maintenance involves regulatory compliance and diligent record-keeping. Many jurisdictions have regulations governing stormwater management, with specific requirements for system design, maintenance, and performance.
