[[File:monitoring-well-subgrade.jpg|400px|thumb|right|Monitoring well stack installed next to underdrain within the LID practice.]][[Monitoring wells]] allow for measurement of water levels in the sub-surface components of LID practices. They are important for sampling procedures and ensuring that the LID feature are performing as intended.'''Construction Steps:'''#Install a cap stand at the required elevation to anchor the monitoring well.#Wrap the perforated pipe with a geotextile sock (to prevent migration of soil into the well).#Anchor the perforated pipe to the bottom of the LID feature.#Install a lockable cap to the top of the standpipe to protect against vandalism.#Install monitoring equipment (e.g., a level logger) if required.'''Key Inspection Points:'''*Pipe is perforated, rigid, and matches design specifications.*Well is installed according to contract documents.*Geotextile sock is wrapped around the perforated portion of the well.'''Mistakes to Avoid:'''*Incorrect sequencing – ensure that standpipe is installed prior to backfilling with granular material.
