Catchbasins . . .
Are Inlets or Manholes
Must Contain a Sump
Are not very useful if streets are also swept
Are applied as drainage controls

Device Performance
Model most suited to determining device performance in parallel
Can evaluate devices in series by running separate models with increasing flows
Device performance a function of flow and area
Manholes
Parallel Collection System
Inlets with Sumps
Series Collection System

Research Results A New Jersey study (Pitt, et al, 1994)
found average removal rates of 32% for suspended solids using catchbasins with a suitable sump.
Pitt & Shawley (1982) found cleaning catchbasin twice per year reduced total residue yields between 10% and 25%.
Pitt & Field (2004) found sediment in catchbasins were the largest particles washed from streets.

Increases the effective surface area of the device by the number of times a vertical line crosses a plate or tube
What are Lamella Plates?
Key Variables
• Fraction of device area with plates or tubes
• Average tube diameter or distance between plates
• Number of plates or tubes in a vertical line
