ABSTRACT This paper proposes a method to include drop manholes in the optimal design of sewer networks. These structures dissipate energy and reduce flow velocity, which is important in hilly regions where high slopes induce velocities that exceed the maximum allowable. The methodology proposed here introduces a new type of arc to represent drop manholes in a model that uses graph theory to achieve the minimum cost design of a sewer network. Also, for the estimation of drop manhole costs, a new cost function is developed based on pipe and manhole cost equations proposed in the literature. The methodology was tested in eight different series of pipe configurations, as well as a real sewer network located in Colombia, varying the pipe material and the land slope. The results demonstrated that the proposed methodology allows for the optimal design of sewer networks in hilly regions while satisfying all hydraulic and commercial constraints.

ABSTRACT This study employs panel data from 41 cities from 2010 to 2019 in the Yangtze River Delta. The entropy weight method is used to calculate the urbanization level. Then, the convergence, panel spatial econometric, and threshold regression models are adopted to examine the convergence and to identify the factors affecting water consumption. The following conclusions may be drawn: Spatial differences in the level of domestic water consumption show a trend of gradual reduction over time; there exists mutual influence of neighboring cities; urbanization positively affects domestic water consumption significantly; the spatial spillover effect of urbanization on domestic water consumption is significantly negative; the promotion effect of urbanization on domestic water consumption is nonlinear, and the promotion effect increases with the increase of the proportion of domestic water and the proportion of public service water. Then, targeted countermeasures are brought forward.

ABSTRACT Low impact developments (LIDs) are control measures to restore the hydrologic regime and enhance stormwater quality. Due to LID’s expensive capital and maintenance cost, the placement of LID controls in a watershed is an important planning task and still an open question in the specialized literature. This study proposes a simulation-optimization approach to place bioretention systems within a watershed to optimize their effectiveness. The Stormwater Management Model (SWMM) and the Non-dominated Sorting Genetic Algorithm III (NSGAIII) were coupled to identify the near-optimal locations of bioretentions for near-optimal quality and quantity controls, considering runoff volume, peak flow, total suspended solids, total nitrogen, and cost. Trade-offs were identified between cost versus other objective functions. The results suggest no specific spatial preference in placement of bioretentions under different rainfall regimes in watershed scale. However, in subcatchment scale, the near-optimal placement under single storm events is either maximum or none, while distributed under continuous simulation.

ABSTRACT A dynamic model, fed with time-variant inputs, of the entire water urban system, coupled with Life Cycle Assessment (LCA) and Life Cycle Costing (LCC), was developed and applied to perform water balance analysis and to assess the environmental and economic aspects of water reuse. Six scenarios using different water sources potable water, rainwater, greywater, and treated wastewater were compared for a future Model City under typical Israeli conditions. The integrated dynamic simulation-LCA-LCC approach considers demands for several water resources and their availability, contains several feedback loops in the water system, and can be applied to any case study. Finally, the combined simulation-LCA-LCC was embedded into an optimisation framework. Results indicate that using treated greywater or treated wastewater for non-potable uses were the most economical scenarios. Business-as-usual scenario, where all urban water functions use potable water, displays the largest negative environmental impacts in all categories compared to using alternative water sources.

ABSTRACT Transitioning urban drainage systems to serve water-smart societies requires the involvement of different disciplines and stakeholders. However, stakeholders have different visions and needs from the transitioning process (e.g in terms of financing, policy adaptation and system management) these also vary between regions and countries. Identifying such different needs for stakeholders is necessary to propose practical adaptation strategies. Therefore, evidence of needs as reflected in policy papers and legislation in seven European countries was collected. Knowledgeable individuals in the urban drainage community were asked about their visions. Results show that whilst there is consensus on the challenges, visions on how to transition are diverse, indicating that more interaction between the different stakeholder groups is required to develop consensus. Additionally, organisational and legislative structures often slow down the necessary change processes.

ABSTRACT When designing a sewer system, the goal is to find the design with the lowest cost while complying with the hydraulic constraints. However, with the emergence of new concerns like climate change and high-density urbanization, those designs must also be reliable and resilient. This is the objective of the present research, to provide an approach for finding low-cost, sewer networks design while considering the reliability and the resilience as a criterion in the selection of the best design. For that purpose, a method is proposed for evaluating resilience and reliability in a variety of designs produced by modifying the objective function of the network’s layout selection model. The methodology was tested in four scenarios using two cost equations and two sewer network benchmarks from the literature. In most of the scenarios, it was possible to find designs with lower cost and higher resilience and reliability than those previously published.

ABSTRACT High nutrient input into waterbodies increases potentially toxic cyanobacteria blooms. Pre-chlorination treatment is excellent for cyanobacterial cell inactivation and dissolved cyanotoxins removal in water supply sources. This study aims to evaluate the pre-chlorination effect treatment on Microcystis aeruginosa cell integrity and its hepatotoxins (microcystins, MC) release and degradation on a laboratory scale. Loss of cell integrity is observed with increasing chlorine concentration. The maximum cell permeability without cell disintegration occurs at 2.5 mg Cl2 L−1. Degradations up to 70% and chlorophyll-a reductions over 70% are observed after 60 min exposure, with complete degradation at 2.5 and 3 mg Cl2 L−1. However, chlorine (Cl2) exposure over 40.66 mg min L−1 is required for microcystins MC-LR (i.e. radicals: leucine (L) and arginine (R)) and MC-RR (i.e. radicals: arginine and arginine) oxidation oxidation to concentrations below the legislation value for water potability.

ABSTRACT This study explores parametric optimization of coagulation-flocculation process using statistically designed experimentation via two-level, five factors full factorial design (FFD) and artificial neural network (ANN). The experimental design was produced using Coagulant dosage ), Fast mixing ), Slow mixing ), Settling time and Seeds kind . Turbidity removal, pH and conductivity variations have been adopted as responses/outputs. The efficiency of Moringa oleifera Lam (MO) seeds cake powder was tested using dehulled (DSCP) and unhulled (USCP) seeds on dam water treated for drinking purposes. Both methods modelled Turbidity removal with high accuracy with a coefficient of determination ( ) of 0.90 and 0.96 for FFD and ANN, respectively. Validation tests also proved to have good efficiency, with a removal rate of 90.42%, which is very close to that obtained by FFD (90.71%) and ANN (92.33%) models. Thus, MO seeds cake powder could serve as a replacement for the chemicals widely used.

ABSTRACT The relative impact of urbanisation (urban sprawl), climate change (rainfall and evapotranspiration) and stormwater disconnection strategies (implementation of green infrastructure (GI)) on a peri-urban stream in the western suburbs of Lyon, France, was investigated using a distributed, physically based model (J2000P). Results showed that ambitious catchment-scale implementation of GI has the potential to mitigate some hydrological effects of urbanisation, especially a drastic reduction of combined sewer overflows. However, GI did not have a large impact on the stream flow regime, especially in the context of climate change, as the stream is dominated by non-urban contributions. Spatially distributed models have the capacity to inform river managers about the extent of implementation of GI needed to achieve given management goals and highlight some limitations of disconnection strategies. Indeed, while GI improved the resilience of sewer networks to global change, it was not sufficient to compensate for the effects of climate change on streamflow.
