Linear Surface Drainage 101: Trench Drain Applications

Linear Surface Drainage 101: Trench Drain Applications

Learn about the benefits of linear surface drainage over traditional point drainage, and then dive in to discuss modular trench drain features, system configurations and design options.

Highlights of a variety of applications where modular trench drain systems can be used and provide practical examples through a selection of case studies.

Surface Drainage 101 is the first of an exciting 2-part series reviewing linear drainage solutions. Surface Drainage 201 will also be presented on March 18, 2016 so stay tuned for updates!

•EN 1433:2002 International Standard
•Applications
•Case Studies

12. Linear Drainage Solutions with Modular Trench Drains
TRADITIONAL POINT DRAINAGE VS
LINEAR DRAINAGE

13. Point Drainage
•Water is intercepted at low points through
catch basins.
•Catch basins are connected to an
underground storm sewer pipe
Use
•Drainage areas with steep gradients.
•Catch basins installed against a curb; with
sloping pavement.
•Often used in conjunction with linear
drainage system.
POINT DRAINAGE
SURFACE DRAINAGE 101 - LINEAR DRAINAGE SOLUTIONS WITH MODULAR TRENCH DRAINS

14. Potential Issues:
•Costly; complex, time-consuming installation
•Impractical; uneven surface
•Increased maintenance costs; poor access,
extra structures
•Inefficient performance; ponding and
blockages
•Deeper pipe inverts; conflict with
underground services
POINT DRAINAGE
SURFACE DRAINAGE 101 - LINEAR DRAINAGE SOLUTIONS WITH MODULAR TRENCH DRAINS

15. Linear Drainage
•Water is intercepted along the entire trench
drain run.
•The interception rate of linear drainage is
greater than point drainage
Use
•Cost effective; less pipe-work
•Larger pavements
•Level surfaces; no ground slope
•Cut off drain; interception on steeper slopes
LINEAR DRAINAGE
SURFACE DRAINAGE 101 - LINEAR DRAINAGE SOLUTIONS WITH MODULAR TRENCH DRAINS

16. LINEAR DRAINAGE BENEFITS
Benefits:
•More efficient at intercepting run-off water
•Ponding is reduced or eliminated
•Shallow depth of construction
•Easier grading
•More economical (fewer manholes, less
pipe, faster installation)
•Easy access along the entire length of the
linear drainage system
•Eliminates the “roller coaster” effect for
vehicular traffic
•Aesthetic solution

•Pre-formed slope is not required to achieve efficient flow

26. CONFIGURATIONS
Stepped-Fall Layout
•Flow similar to a weir configuration
•Improve hydraulic flow and velocity
Step Connectors

27. CONFIGURATIONS
Stepped-Fall Layout
•Constant-depth trench drain sections
•Series of deeper trench drain units interconnected
•Installed gradient created within the trench drain run
•Positive water flow towards outlet
•Ease of installation
•Units are interchangeable

outfall is required at some point.
•Various options regarding location, size and
type of outlet.
•Outlet will influence the discharge of water
from the trench drain system.
•Outlet pipe installed with a minimum 1%
slope to ensure a proper discharge.

31. TRENCH DRAIN OUTLETS
