Cost-Effective Sanitary Sewer Overflow Reduction Planning

Cost-Effective Sanitary Sewer Overflow Reduction PlanningIn order to minimize the total regional cost for a Regional Wet Weather Management Plan (RWWMP), a cost-effectiveness analysis was proposed to optimize the amount of inflow and infiltration (I/I) reduction and capacity improvements needed. Individualized planning was performed for each of the nine wastewater treatment plant service areas that serve the Hampton Roads region in southeastern...Author(s)Dan RubyPhil HubbardAndy LukasRichard StahrCarlos ToroChris WilsonSourceProceedings of the Water Environment FederationDocument typeConference PaperPublisherWater Environment FederationPrint publication date Oct, 2013ISSN1938-6478DOI10.2175/193864713813674298Volume / Issue2013 / 15Content sourceWEFTECCopyright2013Word count144

Wet Weather Management and Sustainability in 21<SUP>st</SUP> Century American Cities

Wet Weather Management and Sustainability in 21st Century American CitiesIn the United States, wet weather water resources management in older cities has often been driven by regulatory pressure favoring traditional infrastructure such as deep tunnel storage systems. A more sustainable approach is suggested, aimed at altering the hydrologic response of urban areas to more closely mimic watersheds with less development. This approach can manage urban water resources...Author(s)R. D. MyersC. CrockettJ.

Quantifying Thermal Impacts of Green Infrastructure: Review and Gaps

Green infrastructure, that is, wet weather management approaches and technologies that infiltrate, evapotranspire, capture, and reuse stormwater to maintain or restore natural hydrologies, can affect temperature in different aspects of the urban environment. Restoration of natural landscape features and local installations of rain gardens, green roofs, green walls, infiltration planters, permeable pavement, or trees and tree boxes can have beneficial effects that reduce (1) stormwater runoff temperatures, (2) heat loss and heat gain in buildings, and (3) the urban heat island effect (UHIE). Rainfall and streamflow in urbanized areas pick up heat from unshaded, exposed man-made surfaces like pavement and rooftops and deliver the excess heat to downstream surface waters to the detriment of stream habitat. Green infrastructure techniques minimize local pavement and rooftop thermal absorption through increased shading and evaporative cooling. These practices also decrease the volume of runoff flowing across heated surfaces and slow the delivery of runoff, allowing more time for heat to dissipate prior to conveyance to surface water bodies. In addition to the insulative properties of green roofs, the increased shading and evaporative cooling result in cooler interior temperatures for buildings during warm weather periods. The insulative properties of green roofs also mitigate heat loss in winter, resulting in reduced energy needs throughout the year. When technologies such as green roofs and green walls are integrated into the design process, greater energy savings for buildings can be realized through reduced heating, ventilation and air conditioning (HVAC) installation size. When green infrastructure is applied at a greater scale in neighborhoods and cities, it tends to reduce the UHIE in understandable though not well-quantified ways, including reductions in exposed heat-absorbing surfaces, increased evaporative cooling, and decreased heat due to reduced HVAC system use. The thermal benefits of green infrastructure can extend well beyond the future city, as reduced cooling needs lower the demand for power during peak loading periods and result in fewer greenhouse gas emissions and less water consumption for power generation. This paper reviews current knowledge on the thermal benefits associated with the use of green infrastructure, identifies gaps in knowledge, and indicates possible directions for future research. Understanding and quantifying the thermal benefits of green infrastructure from the perspectives of emissions avoidance and economic benefits will aid the (re)design of cities to handle energy

Potential of turbidity monitoring for real time control of pollutant discharge in sewers during rainfall events

Turbidity sensors can be used to continuously monitor the evolution of pollutant mass discharge. For two sites within the Paris combined sewer system, continuous turbidity, conductivity and flow data were recorded at one-minute time intervals over a one-year period. This paper is intended to highlight the variability in turbidity dynamics during wet weather. For each storm event, turbidity response aspects were analysed through different classifications. The correlation between classification and common parameters, such as the antecedent dry weather period, total event volume per impervious hectare and both the mean and maximum hydraulic flow for each event, was also studied. Moreover, the dynamics of flow and turbidity signals were compared at the event scale. No simple relation between turbidity responses, hydraulic flow dynamics and the chosen parameters was derived from this effort. Knowledge of turbidity dynamics could therefore potentially improve wet weather management, especially when using pollution-based real-time control (P-RTC) since turbidity contains information not included in hydraulic flow dynamics and not readily predictable from such dynamics.

Integrated Storm-Water Management for Watershed Sustainability

One aspect of integrated watershed management evaluates the impact of development on the local hydrologic cycle and, in particular, drinking water, wastewater, and storm-water infrastructure. Sustainable storm-water management focuses on selecting storm-water controls based on an understanding of the problems in local receiving waters that result from runoff discharges. For example, long-term problems associated with accumulations of pollutants in water bodies include sedimentation in conveyance systems and receiving waters, nuisance algal growths, inedible fish, undrinkable water, and shifts to less sensitive aquatic organisms. Short-term problems associated with high pollutant concentrations or frequent high flows (event-related) include swimming beach closures, water quality violations, property damage from increased flooding, and habitat destruction. A wide variety of individual storm-water controls usually must be combined to form a comprehensive wet weather management strategy. Unfortunately, combinations of controls are difficult to analyze. This will require new modeling techniques that can effectively evaluate a wide variety of control practices and land uses, while at the same time ensure that the flood-control objectives also are met. The results of these new models and novel techniques used for storm-water control then can be incorporated into an evaluation of the urban water cycle for a specific service area to determine whether storm-water controls can provide additional benefits such as reduction of potable water use and reduction of sanitary sewer overflow events.
