www.epa.gov/iaq/moisture Dry wells are to be inspected four times each year and after every storm that exceeds 0.5 inches of rainfall. Whenever possible, dry wells are also to be inspected before a major storm. Inspection consists of measuring infiltration rates and drain times by observing the water level in the test well. The actual drain time of the well should be compared with the time it would take to drain the maximum design storm runoff volume. If significant increases in drain time are noted, or if the dry well fails to dry within the design drainage time, maintenance is required. Dry well maintenance involves removing debris, trash or sediment that may have washed into the well. In addition to the dry well, any roof gutters, sumps or traps connected to the dry well are to be inspected and cleaned or repaired as necessary.
