RE: SEWER FIXTURE UNITS jwooten (Civil/Environmental) (OP) 26 Jul 06 09:44 It seems that DFU applies more to interior conduit.  I have never designed a sanitary sewer system based on DFU.  

The classic sanitary sewer scenario is a community of houses producing X gpm, which is based on population.  That scenario is not a good model for several mixed-use buildings tied to one main sanitary sewer system.  I would like to take the fixture units for each connection to the buildings and convert to gpm (to convert to cfs).  Then I can use Manning's equation to size my pipe.

I understand that sewage flow is not laminar, steady-state flow, and that it is more of an impulse.  However, max flow would be produced by all the fixture units releasing continually until a steady-state flow is achieved.

Please correct me if I am off-course with this line of thought. RE: SEWER FIXTURE UNITS bimr (Civil/Environmental) 26 Jul 06 11:46 Suggest you find a copy of a piping or plumbing handbook. The Piping Handbook by Nayyar published by McGraw Hill has a Table Building Drains and Sewers that show the number of fixture units that may be connected to a certain diameter of drainage pipe. You can probably find the book on .

For example, a 4" dia pipe at 1/4 inch slope can handle 216 fixture units.

The fixture unit is an arbitrary, comparative value assigned to a specific plumbing fixture, device, or piece of equipment. Fixture Unit values represent the probable flow that fixture will discharge into a drainage system, compared to other fixtures.
