Inspect drainage openings regularly
Check leaves, sediment and debris according to the site environment. Inspect more often in wet seasons and follow the site's approved cleaning procedures.
Check covers and foundations
Look for damage, unusual movement, loose bearing surfaces and surrounding settlement. Isolate affected areas promptly and have qualified maintenance personnel assess the issue.
Keep records and verify replacements
Record dimensions, positions and maintenance. When replacing a cover, verify its relationship to the frame and applicable standards instead of buying only by external dimensions.
