  • Development of a geographic information system-based decision support toolset to assess the feasibility of on-site wastewater treatment and disposal options in low permeability subsoils

    Traditional on-site wastewater treatment systems have proven to be unsuitable in areas of low permeability subsoils, representing a risk to human health and the environment. With large areas being covered by low permeability tills, Ireland needs to consider alternative treatment and disposal options to be able to allow further development in these areas and to deal with polluting legacy sites. ...

  • Microbial reduction in wastewater treatment using Fe3+ and Al3+ coagulants and PAA disinfectant

    Wastewater is an important source of pathogenic enteric microorganisms in surface water and a major contaminating agent of drinking water. Although primary and secondary wastewater treatments reduce the numbers of microorganisms in wastewater, significant numbers of microbes can still be present in the effluent. The aim of this study was to test the feasibility of tertiary treatment for ...

  • Innovative modeling approaches improve capacity planning at Orange County sanitation district

    The Orange County Sanitation District (OCSD or District) owns and operates the regional collection system in north and central Orange County, California. The system, which includes over 400 miles of trunk sewers, conveys approximately 250 million gallons of wastewater per day from local sewers within a 471-square-mile service area to two treatment plants. Recently, the District updated the ...

  • Preliminary identification of watershed management strategies for the Houjing river in Taiwan

    The Houjing River watershed is one of the three major river watersheds in the Kaohsiung City, Taiwan. Based on the recent water quality analysis, the Houjing River is heavily polluted. Both point and non-point source (NPS) pollutants are the major causes of the poor water quality in the Houjing River. Investigation results demonstrate that the main point pollution sources included municipal, ...

  • Identifying and Strengthening “Weak Links” in the Fog Management Chain

    ABSTRACTRecently, EPA presented statistics that cited grease accumulation in sewers as the leading cause of sewer blockages resulting in sanitary sewer overflows (SSOs). Such blockages can be attributed to fats, oils, and grease (FOG) discharged from food preparation and manufacturing facilities, concentrated residential areas, and even single family homes. Municipalities and wastewater system ...

  • Waterborne diseases in the state of Mexico, Mexico (2000-2005)

    This paper reports a spatial-temporal examination of waterborne disease data from the State of Mexico, 2000 to 2005, by county as the spatial unit. It was found that the incidence of waterborne disease did not decrease during the period under study. Inequality between metropolitan areas and rural zones was observed. People living in population centres had lower incidence of water-related ...
