Constructed wetlands need to be regularly inspected and maintained to ensure that the system is meeting the intended level of treatment. Like all LID systems, [[Inspections and maintenance#Construction Inspections|construction]] and [[Inspections and maintenance#Assumption Inspections|assumption]] inspections should be undertaken during building and handover of constructed wetlands.

A field data sheet for the inspection of constructed wetlands is available below. You can download (downward facing arrow on the top righthand side) and print (Pinter emoticon on top right hand side) the Wetland Maintenance and Inspection Form developed by Toronto and Region Conservation Authority (TRCA) and CH2M Hill Canada.

Functional, performance, and environmental effects [[Monitoring|monitoring]] can help determine the frequency of routine maintenance and identify the need for more extensive corrective maintenance. Most major [[Inspections and maintenance#Forensic Inspection and Testing (FIT)|corrective maintenance]] for constructed wetlands fall into:
* major structural repair
* bank stabilization
* sediment removal
* unplugging of inlets and outlets
