  • Porirua New Zealand – WaStop® DN225 - Case Study

    Porirua City located 20 km north of Wellington has over 70 storm water outlets into the harbour. A number of these outlets are very flat on their approach to the harbour which generally means they are severely influenced by high tides. The problem with these outlets is that if a rain fall event coincides with a high tide, the ability of the storm water network to discharge is severely restricted. ...

  • Converting rain into drinking water: quality issues and technological advances

    With growing pressures on water supplies worldwide, rainwater harvesting is increasingly seen as a viable option to provide drinking water to an ever expanding population, particularly in developing countries. However, rooftop runoff is not without quality issues. Microbiological and chemical contamination have been detected in several studies, well above local and international guidelines, ...

  • Bacteriological assessment of aquifer storage and recovery (ASR) water in southwest coastal Bangladesh

    Safe drinking water is scarce in southwest coastal Bangladesh. Harvested rainwater and rain-fed pond water are the main sources of drinking water for people living in this area. Both government and non-government organizations are promoting aquifer storage and recovery (ASR) schemes to provide safe drinking water for this population. This study assessed the bacteriological quality of both ...

  • Comparison of biofilm formation and water quality when water from different sources was stored in large commercial water storage tanks

    Rain-, ground- and municipal potable water were stored in low density polyethylene storage tanks for a period of 90 days to determine the effects of long-term storage on the deterioration in the microbial quality of the water. Total viable bacteria present in the stored water and the resultant biofilms were enumerated using heterotrophic plate counts. Polymerase chain reaction (PCR) and ...

  • Carbon footprint and life cycle assessment of centralised and decentralised handling of wastewater during rain

    The most widely used approaches for handling of combined sewer overflows (CSOs) are: (1) storage in smaller retention basins and local decentralised treatment; and (2) storage in larger retention basins and treatment at a central wastewater treatment plant. This paper compares the environmental impact including carbon footprint for these two approaches using the life cycle assessment (LCA) ...

  • Safety device for bottom drainage of fuel storage tanks

    General   One of the routine procedures at a fuel storage tank farm is the periodic draining of water which accumulates at the bottom of the storage tanks. ...


  • Effect of first flush on storage-reliability-yield of rainwater harvesting

    Rainwater harvesting (RWH) entails capture of rainwater falling on a roof and conveyance to a storage tank for later use as domestic water supply. During dry weather, dust and pollutants accumulate on the roof surface and are subsequently washed off with the ‘first flush’ at the beginning of the next rain. Diverting the first flush can improve the quality of stored water but at the cost of ...

  • Case study - Mazzei degas separator selected for Wichita aquifer storage and recovery project

    GDT Degas Separator Selected As Best Method For Entrained Gas Bubbles Removal Wichita, KS The Problem: In the 1990s, the City of Wichita, Kansas developed a water supply plan that included creating a sustainable water supply through the year 2050. The key component of the plan is recharging the large aquifer that lies under the region with 100 MGD of water from the ...

  • Storm Water Plan Case Study

    Global was contracted by a local Road Commission site. The Road Commission site serves as the county level road agency, which maintains more than 1,813 miles of roads and streets and over 250 signalized intersections. The Road Commission contains six sites across the county. Each site is responsible for its particular area. The sites all include maintenance garages, diesel and gasoline ...

  • Two proposals for unlimited fresh water

    The world water crisis may be more serious than generally appreciated. One reason for this is that the main response has been to increase storage of rain rather than to increase the amount of fresh water. Another is that fossil groundwater has been widely seen as inexhaustible. Two fresh water collecting systems are outlined here and it is argued that they have no ultimate limitation, either by ...

  • Water Reuse Terminology

    All water on Earth is used and reused, over and over, in an elegant water cycle. Water reuse occurs in various ways on a daily basis. It happens when a community’s treated wastewater is discharged into rivers or other water bodies. If you live in a community downstream of another, chances are you are reusing water from an upstream town. Scientifically proven advances in water technology ...

  • Cost effective way to harvest estuarine water: variable salinity desalination concept

    Singapore, a small island city-state with some 700 km2 in land area and a population of 4.5 million, is always looking for innovative ways to find new water sources to meet its growing need for water. Rain falling in the urban fringe catchments is not harvested; these areas experience bouts of heavy rain but dry up during the dry season and, as such, the conventional approach of constructing ...

  • Climate adaptive urban planning and design with water in Dutch polders

    The existing water management in Dutch polders is based on independent water systems for each polder. These are featuring artificial stabilized ground and surface water levels. As a result of the local climate the water levels in the polders are not continuously at a constant level. To maintain a stable water table in the polders, the surplus of relatively clean rainwater has to be pumped away ...
