Sanitary sewer and storm sewer crossing clearance?
Sanitary sewer and storm sewer crossing clearance?
(OP)
How close would you cross a sanitary sewer with a storm sewer. The sanitary sewer is an 8" PVC and the storm sewer is a 12" RCP. Normally, I try to keep 18" between the crossings, but I cannot make this happen. Basically, the way it is designed right now, the sanitary is sitting right on top of the storm sewer, with the sanitary being about 8 feet below grade. I know this is less than ideal, but the sanitary is an existing pipe and the storm sewer cannot be lowered (or raised above) the sanitary. Any comments are welcome. Thanks.
