  • GPR goes underground: Pipe Penetrating Radar

    Abstract: Pipe Penetrating Radar (PPR) is the underground in-pipe application of ground penetrating radar (GPR) either robotically or by manned entry to reveal wall thickness, delamination, voids, and other conditions that enable more precise determination of pipeline integrity and verifications for trenchless technology rehabilitation. PPR, when applied to pipe-bursting applications, can ...

  • Redesigning wastewater infrastructure to improve resource efficiency

    Resource efficiency of wastewater management is a question of optimizing at the same time the management of resources in wastewater (e.g. water), the resources spent on treatment and transport (e.g. energy), the natural resources to protect (e.g. the receiving waters), and the anthropogenic resources (e.g. capital). For instance, wastewater can be treated to any given quality, but only at the ...

  • 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. ...


  • Infrastructure Maintenance - An Economic Opportunity

    Public safety and the cost of doing business are deeply impacted when infrastructure is neglected. Here’s a look at the high cost of low maintenance and what can be done about it. A Bridge Too Far There are over 607,000 bridges in the United States. According to the 2013 Report Card for America’s Infrastructure,1 published by the American Society of ...

  • A Path To Sustainable Infrastructure Solutions

    Today, for the most part, our communities’ infrastructure systems are developed and managed separately, by separate utilities and agencies. Sustainable infrastructure, on the other hand, blurs boundaries between our energy, transportation, water and waste systems to implement complementary strategies that benefit more than one system. Among our most important, and difficult, challenges will ...

Like many communities – this ...

  • Necessary driving forces for infrastructure sustainability

    The forces and complex interactions that hinder and promote the application of sustainable infrastructures are discussed along with changes that are needed in our economic-mindset for evaluating project costs. Some existing sustainable projects result from favourable economics. However, many fall in the trash basket as a result of so-called unfavourable economics. One of the key driving forces ...

  • The future evolution of IT in water infrastructure management

    The water industry has been slow to take advantage of information technology (IT), but it is catching up quickly. In many parts of the world, water managers now depend entirely on IT to manage their water supply and wastewater services. IT has become a core part of the business. Computing environments have evolved from individual mainframe computers, through networks based on mini-computers, to ...

  • Managing the NYC Watershed WWTP Upgrade Program- “Re-tooling an Entire Watershed’s Wastewater Treatment Infrastructure”

    New York City has the largest unfiltered surface water supply in the world. Within the 1,969 square miles tributary to the system's 19 reservoirs and three controlled lakes, are 106 non-City-owned permitted wastewater treatment plants, owned by a wide variety of private, public and municipal organizations. In order to avoid filtration of their 1.3 Billion gallon per day supply, New York City ...

  • Optimal planning of water and wastewater management infrastructure for insular areas: the role of water reuse

    The present article estimates the financial benefits of water reuse by calculating the annualised total cost of water and wastewater management, using mixed integer linear programming. The programme is using as input: geographical data, population distribution, and groundwater availability (for a given area), to calculate the qualitative localised water needs, and to estimate the sizes and ...

    Investment in Water Infrastructure The Water Infrastructure Network (WIN) a coalition of the nation’s leading construction, engineering, conservation, labor, municipal and manufacturing organizations, firmly believes that a federal investment of $20 B in our nation’s critical water infrastructure is the single most effective means for creating quality jobs with federal ...

  • House of commons committee on transport, infrastructure and communities

    The Canadian Water and Wastewater Association represents the interests of municipal water and wastewater services in respect to federal or national legislation, policies and programs. More than 24 million Canadians receive drinking water from municipal services and discharge wastewater to those services. The services are provided on a notfor-profit, public service basis. Revenues derived from ...

  • Comprehensive Infrastructure Renewal Program Addresses Aging Water and Sewer Infrastructure in Miami-Dade County

    As industry studies continue to highlight the issues surrounding aging water and sewer infrastructure, policy-makers at the local, state and national level of government are beginning to recognize the problem and make infrastructure renewal programs a priority. One approach that combats the issues surrounding aging water infrastructure is asset management. This approach to infrastructure renewal ...

  • Innovative research program on the renewal of aging water infrastructure systems

    The needs associated with the aging water infrastructure are immense and have been estimated at more than $1 trillion over the next 20 years for water and wastewater utilities. To meet this growing need, utilities require the use of innovative technologies and procedures for managing their systems. To help meet their needs, the U.S. Environmental Protection Agency initiated a research ...

  • Common environmental infrastructure: case study on the management of common effluent treatment plants

    The concept of common environmental infrastructure including common effluent treatment plants (CETPs) became popular in India due to several driving forces. A large number of small and medium enterprises located in industrial agglomerate joined hands in setting up such facilities with financial assistance from government. A study is made on the management of eight CETPs located in different ...

  • Risk–based sequential allocation of competing sanitation infrastructure investments

    Given severe sanitation service shortages, infrastructure interdependencies and extreme scarcity of funding that prevail in many developing countries, the allocation of funds across the three services of providing drinking water, wastewater and sewage and solid waste is vital to their sustained expansion. This paper adopts an approach to resource allocation for the three services based on the ...

  • Environmental infrastructure and socio-economic indicators in San Pedro Sula, Honduras

    Access to water and sanitation was evaluated with respect to socio-economic factors for San Pedro Sula, Honduras (SPS), a medium-sized industrial city. A multidisciplinary analysis was conducted using socio-economic distribution and infrastructure assessments to determine the nature and extent of any existing inequalities. Although piped water access was nearly universal, socio-economic status ...

  • Rethinking Big Water - Is It Time For A New Approach To Municipal Water Infrastructure?

    Las Vegas has long served as a stereotype of human excess: gambling, drinking, sex, all-you-can-eat buffets. But the latest chapter is playing out away from the Strip, in the part of the valley where two decades of booming development have swelled the population to 2 million residents who rely on a dwindling water supply. Ninety percent of the southwestern U.S. city’s drinking water comes ...
