Flow routing in the parallel pipes of a combined sewer system
… and successfully applied to a twin pipe sewer system. The model predicts flow and level for each of the parallel pipes and deals with the complex behaviour which occurs at cross-connections.<br/><br/>The model DUPPERS is an enhancement of the single pipe simulation model DUCTS developed …

Development of a transitioning approach to reduce surface water volumes in combined sewer systems
… and future operational scenarios of a wastewater system operating over one calendar year. Modelling scenarios were conducted removing surface water from selected areas focusing on the volumes requiring pumping and durations of pumping station(s) operation prior to treatment during storm …

Re-Think the Streets: An Evaluation of Green Street Practices as a Method to Achieve Combined Sewer Separation
… the same functional benefits as conventional systems. The purpose of this research is to evaluate the effectiveness of GSI in roadside applications (i.e., “Green Streets”) to reduce combined sewer dependency and provide an alternative solution to sewer separation. Typically, roadways reach the …

Development of a Performance Index for Stormwater Pipe Infrastructure using Fuzzy Inference Method
… nearby streams. Traditionally, stormwater pipe systems were integrated with wastewater infrastructure through a combined sewer system. Many of these systems are being separated due to the impact of environmental laws and regulations; and the same factors have led to the creation of stormwater …

Urban drainage modeling and evolutionary multiobjective optimization for combined sewer overflows prediction and control
… rainfall events, the stress on urban wastewater systems increases. In particular, urban flooding and river water quality degradation due to combined sewer over flows (CSOs) are prevailing problems in urban areas worldwide. In this study we have developed an integrated hydrologic-hydraulic and …

The resource demands and water stress of cities: A study of the U.S. urban food-energy-water nexus
… and piped treated water and wastewater systems depend on energy resources, representing aspects of the food-energy-water nexus. Because water resources are used outside of cities to produce the goods that are eventually consumed in cities, the water stress of cities is impacted by local …

CLIMATE CHANGE IMPACT ON URBAN STORMWATER SYSTEM AND USE OF GREEN INFRASTRUCTURE FOR ADAPTATION: AN INVESTIGATION ON TECHNOLOGY, POLICY, AND GOVERNANCE
… are disconnected from nature and deprived of ecosystem services including flood control, fresh air, clean water, and natural beauty. Due to disrupted hydrology, an urban landscape transforms most rainwater into stormwater runoff which is conveyed off the site through a system of curb-gutter-pipe, …

Aqua.Street.Scapes: Interpreting Natural Hydrologic Processes while Enhancing the Urban Streetscape
… an improved 'great street' in Washington DC. A system of urban aquifers is developed beneath the surface of the street, perched atop the compacted, impermeable soils below. This set of aquifers prevents stormwater from entering the existing combined sewer and allows trees to draw water from this …
