Innovative Technologies For Stormwater And Combined Sewer Management
4/18/2010
Stormwater flows have historically been considered as harmless by the general public and system designers. Recent studies have shown that these flows cannot be dismissed as easily. Chebbo (1992), Marsalek (1997) and Valiron (1992) have shown that stormwater is a source of diffuse pollution with a high source of suspended solids (SS), adsorbed hydrocarbons (HC), nutrient loads (N, P, etc.) and heavy metals (Pb, Cr, etc.), which ultimately influence the quality of the receiving body of water.

Global Approach To Wet Weather Issues: Key Steps To An Improved Water Quality
12/28/2008
Wet Weather issues have evolved over the last generation. From an environmental side issue twenty years ago, they have gained the forefront of environmental concerns. This paper will present the key steps to achieve a global approach to Wet Weather issues. Each of the best management practices available have been ranked and reduced to critical steps that can be implemented sequentially in order to achieve an optimized global approach to wet weather issues.

Evidence Of A Critical Velocity In Underflow Baffle Design For Floatables Control In Combined Sewer Overflows (CSOs)
5/22/2008
Underflow baffles have gained in popularity over the last few years as a viable mean to intercept floatables in Combined Sewer Overflows (CSOs). This has happened in consideration of the extremely low application cost of the solution although the efficiency of underflow baffles has never been clearly proven.
