There is a manhole cover in my neighborhood that rattles every time a vehicle drives over it. What can I do about it?

NSD has two main types of sewer access structures:


  1. A manhole that varies in size from 25 to 42 inches in diameter
  2. A rodding inlet, which is round or oval and ranges in size from 9 to 18 inches


Both structures have solid covers and are normally imprinted on top with "NSD” or “Sewer." Occasionally, there may be a separation between the base and the cover of the manhole or rodding inlet, causing the cover to rattle when a vehicle drives over it. To report a rattling manhole or rodding inlet cover, call the District at 707-258-6000.
