2020 Sewer and Drainage Facilities Design Manual

Thumbnail image of coverEnvironmental Services is updating its Sewer and Drainage Facilities Design Manual (SDFDM). The proposed updates to the manual will improve clarity, formalize and update technical requirements, eliminate obsolete information, and remove any discrepancies between the SDFDM and the City's Stormwater Management Manual (SWMM). In addition, design and formatting changes to the revised SDFDM will better connect users with web-based resources.
