  • An Update on the Columbus Wet Weather Management Plan

    ABSTRACTUndergoing a system wide program for a metropolitan area of over 1 million people to address SSOs is a challenge. The same can be said for addressing CSOs throughout a system. Columbus is addressing both at once, creating a particularly daunting challenge. Columbus submitted one large report, the Wet Weather Management Plan (WWMP), to the Ohio EPA on July 1, ...

  • An Infrastructure Grows · Decentralized Treatment and Recycling Domestic Wastewater

    THE TERM, “decentralized waste-water management,” refers to the process of treating and discharging treated wastewater in the local vicinity where it is generated. Decentralized systems typically use the soil as the final receptor of the treated wastewater instead of discharging to surface waters, which are generally the receptors of treated wastewater from larger centralized treatment plants. ...


  • RBMK-1000 spent nuclear fuel transfer from wet to dry storage

    The process of RBMK SNF transfer from wet to dry storage includes: (a) SNF transport and handling operations at the NPP related with SNF preparation for the wet-to-dry storage transfer; (b) SNF cask delivery to the MCC by rail; (c) SNF transport and handling operations at the MCC; (d) TUK-109 and rail transport preparation for the next shipment to the NPP. The RBMK-1000 SNF handling technology ...

  • Improved wet weather wastewater influent modelling at Viikinmäki WWTP by on-line weather radar information

    Municipal wastewater treatment plant (WWTP) influent is typically dependent on diurnal variation of urban production of liquid waste, infiltration of stormwater runoff and groundwater infiltration. During wet weather conditions the infiltration phenomenon typically increases the risk of overflows in the sewer system as well as the risk of having to bypass the WWTP. Combined sewer infrastructure ...

  • Going Green in D.C. Case Study

    Green infrastructure practices serve as decentralized alternatives to traditional wet weather controls in urban areas where land is limited and sewer infrastructure is often stressed to capacity. Green infrastructure attempts to restore natural hydrologic processes and decreases the quantity of runoff, reduces peak flow rates, and improves water quality. In addition, green infrastructure can ...

  • Low impact development: San Francisco’s green approach to stormwater management

    This paper presents the methods, findings, and policy implications of a comprehensive evaluation of low impact development (LID) techniques for the City of San Francisco. LID is an innovative approach to stormwater management that relies on decentralized, small-scale stormwater facilities and site-design techniques to reduce wet weather flows and to remove stormwater pollutants. The LID analysis ...

  • Can nature help reduce the impacts of climate change?

    Building and managing a well-planned network of natural areas might provide an effective and, in many cases, cheaper solution for coping with natural disasters such as floods or landslides. A new report published today by the European Environment Agency (EEA) explores how ‘green infrastructure’ can help Europe prepare for and reduce the loss from weather- and climate-related hazards. ...

  • What Causes Water Main Leaks?

    The number one cause of water leaks today and moving into the future will be the aging infrastructure. “A large part of the US public water system dates back to the years shortly after World War II, therefore, a significant amount of buried infrastructure is at or very near the end of its useful life.” – Qureshi & Shah, Journal AWWA. When aging infrastructure is combined ...

  • 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 ...

  • Retention Treatment Basin Operation, Maintenance and Budgeting Requirements

     ABSTRACT This paper will provide information to planners, engineers, and owners about operation and maintenance issues and costs associated with Retention Treatment Basin facilities. KEYWORDS Combined sewer overflow, retention treatment basin, operations, maintenance, budgeting. INTRODUCTION ...

  • Ready or not: The Changing Nature of Collection Systems Oversight

    ABSTRACT The collection and conveyance of sanitary wastewater is a principal tenet of sanitary engineering that has helped move developed countries into the modern urban age. The focus of collection system agencies has historically been to convey wastewater to treatment facilities. The operational practices of these agencies have generally been geared toward infrastructure maintenance and ...

  • Watershed characterization and planning to help District meet consent decree case study

    Sanitation District No. 1 of Northern Kentucky has signed the nation’s first wet weather consent decree based on the principles of adaptive watershed management. LimnoTech is working with the District, its gray and green infrastructure consultants, and stakeholders to develop watershed plans that meet requirements of the consent decree for sewer overflows. Problem The ...

  • 10 Years Experience of CSO Management in the United Kingdom

    ABSTRACTThe United Kingdom’s ageing sewerage infrastructure meant that by the late 20th century the country was facing a major environmental problem associated with storm sewage discharges from more than 8,000 unsatisfactory combined sewer overflows (CSOs). Addressing this problem presented a major challenge to the UK water industry, but it is a challenge that has been met by a combination of ...

  • Experience with Local Stormwater Management Programs

     ABSTRACT Local stormwater management programs have traditionally been operated and funded as a function of general government. Increasing requirements to deal with wet weather water quality problems and the devastating impact of flooding have led to increased efforts to expand organizational responsibilities and the need for new and dedicated funding. To provide a cross section of ...

  • Better ways to deal with wastewater

    A city’s wastewater treatment infrastructure is part of the groundwork for the organization of an entire community. This is one of the most costly endeavors for the community and using a centralized system is often not an environmental benefit. There is conclusive evidence centralized sewer collection systems are leaking and causing treatment plant overflows during strong wet weather ...
