SCM3 & SCM 4 - Design & Detail.pcif
Good morning Stephanie. SCM 4 is underground detention, which provides storage for treated water coming out of
SCM 4 (sand filter), where it is slowly released into the existing storm drainage pipe that runs through the site. This is a
closed system. SCM 4 (sand filter) provides 90% nitrogen removal and discharges into an existing conveyance, and
therefore diffuse flow is not required.
I've attached the SCM 3 & 4 Design and Detail sheet from the construction drawings.
Please let me know if you have any other questions, or require any additional information.
Thanks!
Troy Beasley

Lyle,
I am currently reviewing the above referenced project and have the following questions:
• Please provide more details on the Underground Detention SCM 4. Is it considered an open or closed SCM? Does
it provide diffuse flow? If so, please provide details.
Thanks in advance!
