Environmental 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.
The materials posted here will provide you with an overview of the changes:
Environmental Services held information sessions in August on key changes and major improvements to the SDFDM. You can view the materials from those presentations here.
Environmental Services accepted public comment on the 2020 SDFDM from Monday, Aug. 5 until Friday, Sept. 6. The public comment period is now closed.
