Designed To Treat Twice Their Rated(dry weather) Flow, for example

Dry Weather = 100 MGD

Wet Weather = 200 MGD

WPCPs Capture a Percentage of

Urban Runoff Good capture of small storms

First Flush


5/45

Rainfall is captured on roofs, streets, parks, etc.

Runoff typically enters conveyance systems via:

Catch basins

Roof leaders

Conveyance Systems:

Combined Sewers

Storm Sewers

Fate:

Treatment and discharge

Untreated discharge

Modeling of sewers models are:

Comprehensive

Predictive

Unreliable without field data to calibrate/verify

Monitoring of sewers monitors are:

Point-specific

Historic

Reliable when used properly

+=

Reliable, predictive tool for comprehensive analysis

of sewer systems
