What is the minimum top diameter for a storm sump?

Explanation:
Access and maintenance drive the size of a storm sump’s top opening. You need enough room to remove the cover, reach inside, and use cleaning tools or pull out debris and baskets. A sixteen-inch top opening provides that workable clearance for a person to service the interior while keeping the unit reasonably compact to fit where it’s installed. If the opening were smaller, maintenance becomes impractical or unsafe because you can’t easily remove the cover or reach inside. Larger openings would work, but they add unnecessary cost and potential drawbacks without providing additional maintenance benefit. So, sixteen inches represents the minimum that makes routine service practical and safe.
