==Inspections and Maintenance==
Constructed wetlands need to be regularly inspected and maintained to ensure that the system is meeting the intended level of treatment.
===Inspections===
Like all LID systems, construction [[Inspections and maintenance:Construction Inspections]] and assumption [[Inspections and maintenance:Assumption Inspections]] inspections should be undertaken during building and handover of constructed wetlands.
Routine operation inspections [[Inspections and maintenance:Routine Operation Inspections]] and preventative maintenance for the lifespan of constructed wetlands should cover:
*Review as-built drawings, maintenance history, and prepare inspection form prior to site visit
*Ease of access for inspections
*Vegetation management - grass mowed to a height greater than 4-6" and clippings collected, invasive species monitoring and control
*Repair of vandalized areas
*Sediment accumulation
*Mechanical equipment check
*Structural component check
A field data sheet for the inspection of constructed wetlands is attached below.
Functional, performance, and environmental effects monitoring (https://wiki.sustainabletechnologies.ca/wiki/Monitoring) can help determine the frequency of routine maintenance and identify the need for more extensive corrective maintenance. Most major corrective maintenance (Inspections and maintenance:Forensic Inspection and Testing (FIT)) for constructed wetlands fall into:
• major structural repair
• bank stabilization
• sediment removal
• unplugging of inlets and outlets
