GIS based optimal design of sewer networks and pump stations
… for determining the locations for lift stations when gravity flow is not possible. Flows from upstream subwatersheds are transported to the downstream subwatersheds via a force main. The path and destination of each force main in the system is determined by applying the Dijkstra's …

Enhanced Pump Schedule Optimization For Large Water Distribution Networks To Maximize Environmental And Economic Benefits
… and tools to reduce electricity consumption of pump stations of water distribution systems. Based on this ongoing research trend, about a decade ago, some commercial pump operation optimization software introduced to the market. Using metaheuristic and evolutionary techniques (e.g. Genetic …

Carbon Dioxide and Hydrogen Sulfide Emission Factors Applicable to Wastewater Wet Wells
… sample gases were collected from the wet well of pump stations for five days. Using the collected samples the emission rates of carbon dioxide and hydrogen sulfide are estimated.

Pressure, leakage and energy management in water distribution systems
… management via integration and coordination of pump scheduling with pressure control aspects has been created. The method is based on formulating and solving an optimisation NLP problem and involves pressure dependent leakage. The cost function of the optimisation problem represents the total …

Dynamic Markers
… with development reduced its capacity, making pump stations essential for managing water in inhabited areas. Unlike the other forms of infrastructure in the Meadowlands, the presence of the pump station is subdued, its invisibility upholds the illusion that the developments within this …

Indicators for Minimizing Energy Consumption and GHG Emissions at Wastewater Treatment Facilities
… Wastewater facilities use large number of pumps in their transfer stations, treatment plants, and effluent pump stations. All these pumps consume considerable amounts of energy. This study presents a preliminary energy inspection of two facilities from Louisiana. This audit provides an …

Persistent pharmaceutical concentrations in an urban Western Cape Estuary and the effects on microalgal assemblages
… sewage spills due to malfunctioning sewage pump stations, which in turn is likely amplified by load shedding (planned electricity outages to manage demand) intensifying over the last seven years. Findings additionally highlight the potential for small, urban temporary-open closed estuaries …
