Fix-A-Flood (Before It Happens): Optimized Overflow Devices Increase Retention Capacity
By Gianfranco Maragno, P. Eng., And Martin Couture, P. Eng., John Meunier Inc.
Overflow events occur during wet weather when the collection system reaches its maximum storage capacity. Traditionally, a compromise must be struck between the sewer's in-line retention and the risk caused by a higher hydraulic grade line (HGL). To address this dilemma, a careful optimization of the system's overflow weirs is required. This paper introduces the use of linear overflow devices that can increase retention capacity and protect the system against flooding.

Passive Filter – Sustainable BMP For Permanent Stormwater Treatment Of Heavy Metals, Nutrients, Hydrocarbons, And Sediment
By Royal Enterprises America
Passive filtration provides a sustainable alternative to classical drainage concepts for source control of hydrocarbons, heavy metals, and nutrients that endanger our water bodies. In urban areas with high building density, traditional drainage concepts like wetlands are not available, and the concept of decentralized treatment facilities that can be housed in catch basin structures are a viable option for treatment of pollutants.
