Reducing combined sewer overflows by using outlet controls for Green Stormwater Infrastructure: Case study in Richmond, Virginia
William C. Lucas,David J. Sample +1 more
TL;DR: In this article, two Low Impact Development (LID) Green Stormwater Infrastructure (GSI) alternatives applied within a 7.05-ha catchment of the Shockoe Creek tributary of the James River in Richmond, Virginia were compared to two non-LID alternatives: existing conditions and tunnel storage.
Journal ArticleDOI
Coupling urban event-based and catchment continuous modelling for combined sewer overflow river impact assessment
TL;DR: In this paper, a coupled scheme is presented to assess the impact of combined sewer overflows (CSOs) on a river system in Torrelavega (Spain) in order to provide the most likely state of the receiving river when a CSO occurs.

Separate and combined sewer systems: a long-term modelling approach
Giorgio Mannina,Gaspare Viviani +1 more
TL;DR: Compared systems showed different responses in terms of effectiveness in reducing the discharged mass to the RWB in relation to the particular pollutant taken into account, emphasising the concept that case-by-case solutions have to be undertaken.

Cost-efficiency of RTC for CSO impact mitigation
TL;DR: In this paper, a costbenefit analysis of several static and dynamic solutions to mitigate CSO impact, based on the case-study of the Kessel-Lo catchment in Flanders/Belgium, is presented.

Combined sewer system versus separate system – a comparison of ecological and economical performance indicators
TL;DR: This paper aims at comparing the cost-effectiveness of the two main types of urban drainage systems, that is, the combined sewer system and the separate sewer system, based on the analysis of simulations, on the basis of literature data and simulation of specific cases.

Indicators for the sustainability assessment of wastewater treatment systems
TL;DR: In this article, a general assessment methodology is proposed to evaluate the trade-offs made when selecting sustainable wastewater treatment systems, based on which a complete set of sustainability indicators are used.

A new database on urban runoff pollution: comparison of separate and combined sewer systems.
TL;DR: The traditional separate and combined sewer systems are compared using a pollution load balance and the results show that the separate system is superior to the combined for some parameters only, such as nutrients, whereas for other parameters, e.g. heavy metals and COD, the combined system yields less total loads.
Journal ArticleDOI
Is combined sewer overflow spill frequency/volume a good indicator of receiving water quality impact?
TL;DR: In this paper, an integrated model was applied to the urban wastewater system of a semi-hypothetical catchment to test the veracity of the assumption that the frequency or volume of combined sewer overflow is a good indicator of receiving water pollution impact.

CITY DRAIN © - An open source approach for simulation of integrated urban drainage systems
TL;DR: CITY DRAIN was developed in the Matlab/Simulink (C) environment, enabling a block wise modelling of the different parts of the urban drainage system (catchment, sewer system, storage devises, receiving water, etc.).

Sewer systems and performance indicators-into the 21st century
Richard Ashley,Peter Hopkinson +1 more
TL;DR: In this paper, a review of the current framework for measuring and assessing performance of UK water service providers is presented, highlighting the complexity and high levels of performance assessment set by the regulators and the difficulty of making meaningful comparisons between WSPs.
