What Happens When Everyone “Flushes” at the Same Time? – Case Studies on Management of Wet Weather Flow Events

摘要

Many utilities are faced with the challenge of providing additional peak wet weather treatmentcapacity at their wastewater treatment plants and within the collection system. Unlike in the pastwhere most of the regulatory focus has been placed on larger utilities, the pressure is nowextending to small and mid-sized utilities. As progressively more utilities make improvements toaddress regulatory requirements and begin to treat higher rates of influent flow, it is increasinglyimportant to understand and document treatment strategies and the operational nuancesassociated with them. This provides six examples of facilities where wet weather strategies haveor are going to be implemented to increase wet weather treatment capacity.
