  • WaStop prevents flooding on Meritt Island Case Study

    Problem: Brevard County converted two borrow pits into retention ponds for polluted stormwater collected from the Pine Island Canal. This waterway collects stormwater from a 5,970 acre drainage basin, including citrus groves and agricultural land, and deposits it into the Indian River. A method for allowing water to flow from the canal to the converted borrow pits and to ...

  • Pile driver used in rain and sewage diversion reconstruction

    Rain and sewage diversion refers to the way of discharging sewage and sewage, which are transported by one pipe for discharge or subsequent treatment. Rainwater can be discharged directly to the river through the rainwater pipe network; the sewage needs to be collected by the sewage pipe network and sent to the sewage treatment plant for treatment. After the water quality is qualified, it can be ...

  • Desalination in the Caribbean

    Islands have long relied on the process to supplement natural water supplies More than 7,000 islands of the Caribbean Archipelago are scattered over a million-square-mile area between North and South America. Some smaller islands are naturally dry, but some volcanic islands — like Grenada and St. Lucia — are well forested and provide significant water catchment to support ...

  • San Antonio’s Continuing Focus on Water Sustainability

    Endangered salamander provided unlikely impetus for conservation efforts Forty years ago, the citizens of San Antonio, Texas, used an average of 200 gallons of water per day per person, far over the national average. This drew the ire of surrounding cities due to the overuse of a shared aquifer. Today, water use has been cut to 117 gallons per person per day, and San Antonio has earned the ...

  • Brackish Water as a Resource

    There’s a great deal of talk and debate about the value of treating brackish water, or water that is more saline than fresh water, but not quite as saline as seawater. Brackish water can result from the mixing of seawater with fresh water, as in surface waters such as estuaries or other watery ecosystems, or it can occur underground in aquifers. Salinity Levels Although ...

  • Design and operation of a rainwater for drinking (RFD) project in a rural area: case study at Cukhe Elementary School, Vietnam

    Since 2014, a well-designed rainwater for drinking (RFD) project has been successfully operating at Cukhe Elementary School, near Hanoi, Vietnam. During that time, daily rainfall data, water consumption, water quality and questionnaires to the community were prepared. Several concerns over the design and operation of RFD projects, such as lack of sufficient rainfall data, water quality ...

  • Evaluation of the optimal size of a rainwater harvesting system in Sicily

    In the Mediterranean area, water scarcity represents a critical issue due to the increasing water demand related to the population growth and the expansion of urban and industrialized areas. Rainwater harvesting (RWH) may be an effective alternative water supply solution to deal with water scarcity in order to reduce non-potable water needs. The reliability of RWH systems is greatly affected ...

  • An evaluation of hydrologic modeling performance of EPA SWMM for bioretention

    Recent techniques should be investigated in detail to avoid present and future problems of urbanization like flood, drought and water pollution. Low Impact Development (LID) Best Management Practices (BMPs) such as bioretentions, green roofs, rain barrels, vegetative swales, and permeable pavements have been implemented to diminish the adverse effects of urbanization. In this study, a ...

  • Addressing urban water scarcity: reduce, treat and reuse – the third generation of management to avoid local resources boundaries

    Urban growth leads to geographically concentrated demand for water and food – and to growing volumes of wastewater and organic waste. Left unattended by city authorities, both local and planetary resources boundaries for water and nutrients will be transgressed. A novel partly dynamic ‘flexible water balance’ is developed to explore ways to address a looming water crisis. A systems-based flow ...

  • An approach to quantifying rainwater harvesting potential using imagery, geographic information systems (GIS) and LiDAR data

    Geographic Information Systems (GIS) software is used to analyze rainwater harvesting potential in Escambia County, Florida, USA. The approach presented can be replicated using LiDAR data, and the infrared spectrum of National Agriculture Imagery Program (NAIP) imagery. GIS surface maps are analyzed in combination with local utility consumption data to determine potential reductions in potable ...

  • Disinfection of roof harvested rainwater for potable purpose using pilot-scale solar photocatalytic fixed bed tubular reactor

    The potable use of harvested rainwater is limited, mainly due to contamination with various pathogenic microorganisms. Disinfection of microorganisms by solar photocatalysis is emerging as a promising technique for drinking water treatment. The present study deals with the preparation of Ag-doped TiO2 by the sol gel method, and its immobilization over the inner surface of the Pyrex glass pipes ...

  • Taking advantage of stormwater, a plentiful, free resource

    As the saying goes, when it rains, it pours. Rain and snow and other types of precipitation are a resource more organizations would be wise to take advantage of as water scarcity increases around the globe. Stormwater, precipitation that isn’t absorbed into the ground, is a freely available resource, but is there enough of it to make a difference? The amount of runoff varies from storm ...

  • Experimental study on performance of sand filter layer to remove non-point source pollutants in rainwater

    Clogging characteristics of conventional sand filter layers with different grain-size distributions were experimentally studied to estimate their filtration capacity to capture non-point source pollutants in an artificial rainwater reservoir. A series of laboratory-scale chamber tests was conducted for artificial urban runoff synthesized with non-point source pollutants collected from a real ...
