  • Nemo BF Progressing Cavity Pump With Integrated aBP-Module By NETZSCH Reduces Sewage Sludge Bridge Building
    the aBP Module eliminates high media cohesiveness that can cause repeated entanglements and bridge building The result is significant reduction or elimination of wastewater treatment plant operational shutdowns TheaBP Module is made up of a hopper extension with two spoked wheels attached to its internal sides Sitting deep inside the hopper and very close to the walls the turning wheels generate the effect of moving hopper walls which creates a shearing effect in the medium This shear effect tears the bridges apart in the early stages of formation so the mix can be conveyed continuously The structured surface of the stainless steel wheels further supports this effect and assists agitation in the hopper The middle of the chute remains free and the fill level can be assessed at any time and readjusted if necessary The wheels are driven by independent worm gears with settings that can be tailored to each medium being conveyed To convey larger quantities to a wastewater treatment plant the aBP Module is also available in a version with four wheels two on each side The NEMO BF progressing cavity pump was specially developed for highly viscous to compacted media and ensures pressure stable low pulsation conveyance Sewage sludge drops directly out of the hopper chute into the force feed chamber As the dewatered flocculated sludge is no longer free flowing it is moved evenly via the aBP Module s patented horizontally positioned screw conveyor into the pump chamber itself Between the progressing cavity pump s rotor and stator equal cavities are formed that take up the medium and transport it on with the turning of the rotor In this process dosing can be precisely controlled by the speed to achieve a continuous material flow The filling of the conveying cavities is supported by the hopper shaped

  • KC Masterpiece Revolutionary Combined Sewer Overflow Control
    Overflow Control Program stakeholders to quickly access and utilize terabytes of the city s sanitary sewer data largely collected as part of the city s Overflow Control Program The application is the first to combine multiple off the shelf technologies for the assessment and use of sanitary sewer data Kansas City created the application using the Web Application Builder produced by Esri The city s sanitary sewer data which includes CCTV video footage field investigation reports smoke testing reports and manhole inspections are analyzed and categorized by a data management technology called InfoMaster produced by Innovyze The sanitary sewer application is changing the way our project teams serve our customers and the way we address the challenges of our aging sewer system said Andy Shively engineering officer for Kansas City Water Services Previously this kind of data had to be accessed using specialized desktop software or would need to be shared with project teams and subcontractors using massive storage drives Using these analytical engines Kansas City is able to mine more than 30 terabytes of existing sewer condition data to produce heat maps which identify portions of the sewer system that require the most urgent attention The survey information in the app is also searchable providing project teams with detailed information that can be accessed using smartphones or tablets from the field Additional sewer surveys conducted as part of the city s Overflow Control Program are expected to generate up to 50 terabytes of data After releasing the sanitary sewer application Kansas City has plans to develop a custom portal which will contain access to a series of applications such as private inflow and infiltration information field management applications and flow metering viewers Building a legacy for Kansas City requires strategic and datadriven solutions that maximize benefits for our community said Shively This leading technology initiative is important for the strategic and long term plan for our utility and it is paving the way for better service and smarter solutions for future generations Green vs Gray The analysis and classification of this massive amount of data is helping project teams associated with Kansas City s Overflow Control Program develop and improve upon both green and gray infrastructure solutions Kansas City s federally mandated consent decree allows for the replacement of gray infrastructure with green solutions when those plans are demonstrated to be similar in both cost and performance Because the Overflow Control Program represents the largest infrastructure investment in Kansas City s history city officials are committed to using this investment to encourage future neighborhood investments In an effort to leverage this investment for the betterment of local neighborhoods Kansas City has allocated more than 68 million for the installation of green infrastructure projects This investment is already proving to be successful both in the reduction of combined sewer overflows and in strengthening the local community In 2012 the completion of Kansas City s nationally recognized green infrastructure pilot project showcased the community and environmental benefits of incorporating green infrastructure

  • Making The Grade A Six-Point Plan To Regain America’s Infrastructure Leadership
    situation is exacerbated by a poor understanding among both political leaders and the general public of the economic benefits of strong infrastructure and the downside of not investing in infrastructure While moves are afoot to improve both infrastructure spending and quality the U S did not rank high in either at the time of the report The United States currently spends just under 2 percent of its gross domestic product on infrastructure while most estimates show Europe at closer to 5 percent Emerging market economies such as India and China invest at much higher rates from 9 to 11 percent according to some estimates The current World Economic Forum Global Competitiveness Index ranks the United States 14th in infrastructure quality behind Singapore the United Arab Emirates and Hong Kong along with a number of European nations such as France and Germany The U S is seeing the ramifications of deferred maintenance and lack of investment even as we are also beginning to experience an increase in severe weather events that would stress brand new infrastructure let alone systems that are decades old The fragmentation of the infrastructure industry in this country may be the most critical factor to overcome If as the ASCE points out infrastructure can be viewed as our nation s nervous system our current methods of procurement planning design construction and operations are much too compartmentalized and disconnected to create an effective outcome Siloed responsibilities only exacerbate these challenges the report asserts Whether the discussion is about improving infrastructure resiliency to withstand natural disasters or to keep the nation s economic leadership in a highly competitive global environment there is consensus that breaking down jurisdictional and operational barriers and looking at infrastructure in more integrated ways are key factors in meeting these challenges At the same time new technologies and processes have evolved in recent years for the design engineering construction operation and maintenance of infrastructure that are superior to previous ways These new technologies and processes can help us approach infrastructure as integrated networked smart systems rather than as isolated civil engineering projects The business and financial models that control the interactions among stakeholders were established for an earlier America that no longer exists To begin addressing the current situation the report suggests a series of steps Start with integrated infrastructure planning The key to integration at the actual design engineering construction operation and maintenance stages is to start by empowering planners to envision and model the data informed city in an integrated framework of infrastructure systems With the intelligent technologies currently available we have the capability to build infrastructure for lower carbon emissions and greater sustainability and longevity And as we think to the future advanced technologies working in harmony will enable us to push existing boundaries and drive further innovation Modernize project planning and delivery approaches The purpose for and demands on infrastructure have changed but the protocols for developing public projects have not kept pace There has been a failure to adopt modern

  • WWEMA Window ‘Buy American’ March To The Sea
    preserve their way of life and to get re elected I encourage you to take a step back and think independently about the unintended consequences that the proliferation of this language may cause For water and wastewater projects this language first appeared under the American Recovery and Reinvestment Act of 2009 ARRA along with an enormous infusion of federal dollars ARRA required that all iron and steel as well as manufactured goods used in a project with this public funding comply with Buy American provisions The chaos that ensued and the waivers that had to be issued particularly around manufactured goods kept many a contractor employed but created an administrative and cost burden for manufacturers engineers municipalities and state primacy agencies Just as we managed to get out from under that morass the 2014 Consolidated Appropriations bill came along where Buy American requirements for iron and steel was snuck into the bill with a quick floor vote no debate no discussion no independent thought Right now Congress is debating amendments to the approval of the Keystone Pipeline that if passed will create an unparalleled expansion of domestic content requirements to a commercially built project paid for entirely without federal funding This amounts to an unfunded government mandate placed on a privately constructed privately funded infrastructure project Lest you think this is only happening in the U S Congress I refer you to New Jersey Senate Bill No 1811 reported out of both chambers on December 11 2014 which states that all manufactured or farm products used in a project shall be products of the United States While this appears to apply to purchases made by the Board of Education history tells us that once specific language finds its way into legislation it often finds its way to other legislation through the convenience of the cut and paste function in Microsoft Word So what are some of the unintended consequences that this language generates Disruption of long standing supply chains In today s global economy it is almost impossible to find a product particularly manufactured goods that don t contain some non U S parts This provision is particularly difficult to understand implement and enforce Increased project costs Examples are beginning to surface where component costs for U S compliant products have been up to 400 percent more than non U S compliant products but because they are only a small part of a project the project never exceeds the 25 percent threshold This leads to enormous cumulative cost increases that are never fully documented or vetted Creation of monopolies This language creates monopolies where a few U S companies benefit to the detriment of many many other U S companies These anti competitive measures hurt the U S economy and result in lost revenue and jobs not only in the U S iron and steel industry but in closely related industries that support these projects Trade restrictions lead to retaliation Many of our largest and most critical trading partners such

  • Busted Pipes DC Demonstrates The Rule Not The Exception
    a major U S city has been disrupted by failed water infrastructure And with portions of our country s water infrastructure approaching 100 years old it certainly will not be the last particularly in older cities in the northeastern part of the country Above ground structures like roads and bridges crack and develop potholes as precipitation freezes and thaws or as snow removal breaks down pavement and scrapes away at road surfaces Underground structures like water mains sewer pipes mass transit tunnels electrical and gas lines and telecommunication piping are also susceptible to damage and can leave communities at a loss for basic public services if they fail The fact is that local governments and their utilities face an ongoing risk of disrupted water service with each winter that passes And as D C s recent troubles show even the best prepared utilities are vulnerable The importance of maintaining existing infrastructure is imperative particularly the underground assets that ensure the day to day delivery of safe potable drinking water and removal of sewage to treatment plants Often the infrastructure that is out of sight is also out of mind however few communities that have experienced a broken water or sewer main can forget the ordeal of suddenly losing water managing a sewage filled basement or having flooded streets houses or businesses Many utilities already strain to balance financial responsibilities with meeting capital needs and regulatory requirements Large expenses for unanticipated emergency situations don t make it any easier to meet these goals and mandates Yet despite the necessity of reliable water service our current investment in infrastructure on a national scale remains a drop in the bucket relative to what s needed in order to be proactive and preventative It is estimated that across the country less than 1 percent of water mains are replaced annually contributing to a backlog of infrastructure repairs With one decade s worth of water main repairs projected to cost more than 1 trillion playing the game of catch up is hugely expensive The financial outlays of increased manpower and emergency maintenance typically get tacked on to already stressed city budgets This means that states and their taxpayers are left on the hook for contingency funds when water infrastructure breaks down But the picture is not all bleak Despite the national numbers many utilities do invest substantially in ongoing maintenance and take proactive measures to stay ahead of the infrastructural failure curve While these efforts won t fix our infrastructure troubles overnight skilled and proactive utility management can help make the difference The best prepared managers have five things in common The first is that they know their system inside and out and implement ongoing asset management programs It s one thing to have significantly aged pipes carrying a city s water it s a different story if the utility doesn t know these pipes exist and might pose a risk The second is setting aside contingency funds so that necessary emergency repairs don t
