  • Green infrastructure and flood management - Promoting cost-efficient flood risk reduction via green infrastructure solutions

    Executive summary Europe's floodplains once covered wide stretches along European rivers and were valued for their high ecological importance. Over a number of years they have been cleared for agricultural purposes and changed through urban expansion and artificial flood control structures. Existing natural waterways do not always have the capacity to bear any excess water which can lead ...

  • Reduction in water losses in water distribution systems using pressure reduction valves

    Water loss is a phenomenon frequently observed within water distribution systems (WDSs), that is considerably worsened by an excessive pressure throughout the network. As an alternative option to pipe replacement, the use of pumps working as turbines, throttle control valves (TCVs), or pressure reduction valves (PRVs) can be used to reduce leakage. For a preassigned number of these devices, ...

  • Trihalomethane reduction in drinkable water by controlled chlorination and use of hydrogen peroxide

    The reduction of trihalomethane (THM) formation in the water treatment process by a controlled chlorination of ammonia and successive quenching with hydrogen peroxide has been studied. The optimum values of the process parameters have been determined with a calculation programme that makes use of the kinetic constants determined with the water to be treated. The obtained data have been verified ...

  • Determining the true cost of water use reductions case study

    Challenge: Water risk and related business continuity assessments typically consider availability, quality, stakeholder and delivery infrastructure risks. A primary mitigation measure typically involves use reduction and conservation, assuming the costs of such efforts can be justified. Prior to our involvement, a leading food manufacturer found it difficult to invest in water ...

  • Chemical Use Reduction, Recycling for Packaging, Waste Reduction and Energy Use Reduction: Robert Bosch Australia

     Background Robert Bosch Australia was established in 1954 in Clayton, Victoria. The main manufacturing plant remains there to this day. The company has some 1,150 employees in Australia. Robert Bosch manufactures and distributes a wide variety of products from electronic consumer goods, to industrial hydraulics, to hot water systems. The focus of activity in Australia is ...


  • Enhanced Reductive Dechlorination (ERD) and In Situ Chemical Reduction (ISCR) using EHC®

    CH2M HillUnited States Marine Corps Site, North Carolina Summary Site groundwater was impacted with chlorinated volatile organic compounds (CVOCs) at concentrations as high as 80,000 ppb. A total of 24,100 lbs of EHC was injected into areas of elevated CVOC concentration to yield enhanced in situ chemical reduction (ISCR). Six months after the EHC injection, TCA levels had decreased ...

  • The role of process water in pathogen reduction

    The USDA’s Pathogen Reduction/Hazard Analysis and Critical Control Point (HACCP) rule in July of 1996 required all meat and poultry slaughter plants to adopt a system of process controls to prevent food safety hazards. It contained four components: standard operating procedures (SOPs) for sanitation, HACCP plans, generic E. coli testing and Salmonella performance standards. With the ...

  • A multifaceted approach to clear water reduction

    The Heart of the Valley Metropolitan Sewerage District provides wastewater conveyance and treatment services to five communities. The District is faced with meeting the challenges of growth coupled with aging infrastructure. In particular, the wastewater conveyance and treatment systems suffer from extreme wet weather-related peak flow events due to excessive clear water that enters the older ...

  • Peatlands: hotspots for emissions reductions

    Peatlands play a critical role in climate regulation, storing twice as much carbon as the entire world’s forest biomass and emitting large amounts of carbon when drained. Peat carbon stocks are distributed worldwide. The mitigation potential is very significant, but possible future possible emissions as well if no rapid action is taken to protect and restore them. The UNFCCC provides ...

  • A vision for the practice of risk reduction

    Disaster risk is rising rapidly. The poorest and most vulnerable people are hit hardest. Many hazards are becoming more frequent and less predictable as a result of climate change. At the same time, environmental degradation erodes nature’s ability to regulate them, and to provide food and water. The result is that more people are caught in a vicious circle of poverty, risk and ...

  • Problem solving bulk reduction

    The plant, built by Tanks and Vessels, processes food and vegetable waste with the help of Mono’s progressing cavity pumps and Munchers. The organic material is fed into the process in its raw form where it is finely macerated by a Mono Muncher. The homogenous slurry is then transferred to the digestion tanks to produce a useful end product, liquid soil conditioner, which can be sold to ...
