If so, chances are good that we’ll need to get to it at some point to perform maintenance. Keep manholes and cleanouts (small cement boxes or cylinders) clear of debris and landscaping for ease of access. If you have a utility structure in your yard and don’t know what it is, call our Field Operations Department at 707-644-8949, ext. 1702. View photo examples that show a cleanout that is covered by landscaping (PNG) and a cleanout that is properly exposed (PNG).
