  • Hitting the Bull`s-Eye in Groundwater Sampling

    Many commonly used groundwater sampling techniques and procedures have resulted from methods developed for water supply investigations. These methods have persisted, even though the monitoring goals may have changed from water supply development to contaminant source and plume delineation. Unfortunately, the use of these methods can result in an incorrect understanding of the contaminant ...

  • Integrated water resources management and drought risk management in Japan

    Japan has experienced several severe drought disasters in the past and is still suffering from drought conditions in some parts of the country every year. To cope with the drought disasters, Japan takes three types of countermeasures: (i) water resources planning and development as supply side measures; (ii) promotion of efficient water use as demand side measures; and (iii) coordinated ...

  • ACTIFLO® Clarifiers are Heart of Antioch, CA Recycled Water Facility

    Due to a number of economic and ecological factors, the California State Water Resources Control Board requires power plant developers to evaluate the use of recycle water for cooling tower needs. For this reason, Calpine (a power plant developer) formed a public-private partnership between itself, Bechtel Enterprises and the Delta Diablo Sanitation District (DDSD) to build a new recycled water ...

  • The water and energy nexus

    The water and energy nexus The interdependence between water and energy has been more widely recognized during the last few years. In the USA, the Energy-Water Nexus initiative was initiated in 2004 as an informal DOE (Department of Energy) National Laboratory project to develop a better understanding of the link between the nation’s energy and water supplies. The laboratories ...

  • Innovative Reclaimed Water Reuse to Provide Potable Water Supply Downstream Augmentation Project

    The purpose of the Downstream Augmentation Project is to develop a water supply source for Tampa Bay Water without causing a net impact to flows from the Hillsborough River and Tampa Bypass Canal. The goal of this innovative project is to use reclaimed water from the City of Tampa to augment flows, in the river and canal, downstream of existing water supply intakes. This would allow potable ...

  • SWRO Plant in Agadir, Morocco - Case Study

  • Private sector involvement in drinking water supply in Ghana

    Two approaches by Private Sector Involvement (PSI) in drinking water supply are followed in Ghana. In the urban areas the public utility (Ghana Water Company Limited) now has private sector management via a management contract, whereas in the small towns and rural areas the responsibility for water services is decentralised. The District Assemblies use the Community Water and Sanitation Agency ...

  • Water Operator Partnerships:Why use partnership approaches?

    Today, almost 1 billion people live without access to improved drinking water sources and 2.5 billion lack access to improved sanitation. In order to reach Millennium Development Goal 7 (MDG7), access to sanitation has to be given to at least 1.5 billion and a safe water supply to 500 million before2015. Although the situation is better for water supply than for sanitation, the ...

  • Risk management of transboundary water resources using the green supply chain approach

    The problem considered is the coordination of the ecological risks of all stakeholders in a transboundary river basin using the 'green' (environmental) Supply Chain (SC) approach. Using a combination of two managerial concepts – 'the environmental SC' and 'the house-of-quality' – a decision-making model that quantitatively estimates the integrated risk level is constructed. A mathematical model ...

  • Drinking Water Analysis Guide

    Public Water Systems (PWS), regulated by the United States Environmental Protection Agency (USEPA), provide drinking water to 90% of Americans. Water systems and laboratories testing drinking water for Safe Drinking Water Act (SDWA) compliance must be certified and must use USEPA approved methods, which are developed by the USEPA, other government agencies, universities, consensus method ...

  • Stochastic modelling of the hydraulic performance of an onsite rainwater harvesting system in Mediterranean climate

    The performance of onsite rainwater harvesting (RWH) system in Mediterranean climate was assessed. A stochastic model quantifying the necessary storage, as a function of rainfall (frequency, depth), roof area, residents’ number, specific water use (toilet flushing, laundry) and the required efficiency was developed. Two performance indicators were calculated: water saving efficiency (RSE) – ...
