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.<br>
Construction Steps:<br>
#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.<br>
Key Inspection Points:<br>
*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<br>
Mistakes to Avoid:<br>
*Incorrect sequencing – ensure that standpipe is installed prior to backfilling with granular material<br>
