Report preaches the potentials for Rainwater Re-use

  
  
  
  
  

 THe National Resources Defense Council (NRDC) just issued a report titled "Capturing Rainwater from Rooftops" highlighting the potential for rainwater re-use or rainwater harvesting as its sometimes referred to for complementing municipal water supply needs.

The NRDC analyzed the total volume of rooftop rainwater potentially available for capture and use (based on rooftop area and average annual rainfall) in eight U.S. cities, as well as the volume of water potentially available for use under various capture, storage and usage scenarios.  The result of the analyses showed that the volume of rooftop runoff, if it were to be completely captured, would be enough to meet the annual water supply needs of between 21 percent and 75 percent of each city’s population.

NRDC’s study shows that a substantial opportunity exists to use rooftop rainwater capture as an efficient, effective water resource management approach.

There are several factors that could affect the use  and benefit of re-using rooftop runoff (local regulations, existing infrastructure, etc.) however this study shows the potential is there, and rainwater harvesting represents a valuable tool municipalities, developers, property managers and homeowners can use to meet their water supply needs.

Second Round of Infrastructure Grants Announced

  
  
  
  
  

The Executive Office of Housing and Economic Development has announced that it has made available the application materials for its latest round of the MassWorks Infrastructure Program.

The program is a consolidation of six former grant programs and provides public infrastructure financing to support economic development and job and housing creation.  This includes transportation improvements in small, rural communities, mixed use developments, and redevelopment of previously developed sites.  All the relevant materials regardind the program are available at www.mass.gov/hed/massworks

The submission period for grant application runs between August 27 and September 10, 2012,  so there is still plenty of time to put together an application.  The grant award decisions will be made by the end of October. Last year's program awarded grants to 42 communities throughout Massachusetts; projects that are set to begin construction this spring.

If you have questions about the MassWorks Infrastructure Program or how it could apply to you or your organization, please contact Mark Bartlett at (508) 747-7900 extension 131.

Massachusetts Releases report on Water and Wastewater Infrastructure

  
  
  
  
  

The Massachusetts Water Infrastructure Finance Commission just released a report that the State is facing a $21 billion funding gap for water and wastewater infrastructure over the next 20 years.

Former Norfolk Ram employee and co-chair of the commission Carolyn Dykema stated: “Water is one of our most basic needs, yet we often take the infrastructure that delivers it to our homes and businesses for granted. By making investment in our water system a priority, we are also prioritizing economic growth, job creation, and the sustainability of our communities. This report highlights the work we need to do to fund and maintain this important public asset and lays out a road map for creating a 21st-century water infrastructure system to meet the needs of our Commonwealth.”

Water Infrastructure Committee Chairs -Sen. Jaime Eldridge and Rep. Carolyn Dykema.

The Commission's report determined that a significant increase in spending and funding will be needed to address this funding gap and they have laid out several strategies to do this, including:

  • Sustaining current Revolving Fund investments
  • Establishing a trust fund
  • Promoting BMPs to reduce costs and find efficiencies
  • Promoting environmental sustainability and innovation

as well as several other strategies.

An innovative infrastructure sustainability rating system

  
  
  
  
  

         Infrastructure projects have to be carefully prepared because they have lasting impacts on our future. Infrastructure, like highways and bridges, are designed to last a long time – from 20 to 80 years. Because of the longevity of these structures each decision has to be considered and each project has to include sound sustainability practices. The problem is that for infrastructure projects outside of buildings, no systems have been developed to measure sustainability yet. Construction of buildings has the LEED rating system, however no such system existed for infrastructures.

        The Institute for Sustainable Infrastructure, ISI, was created in 2011 by three members: the American Council of Engineering Companies (ACEC), the American Society of Civil Engineers (ASCE) and the American Public Works Association (APWA). The main motivation was to found an institute that could promote the evolution of sustainability principles and practices in the engineering infrastructure field. The ISI strives to be a useful institute that policymakers, regulators, owners, agencies, engineers and many others can consult to have sustainable infrastructure solutions.

The ISI is using a new infrastructure sustainability rating system: envision, Version 1.0. This system is designed to rate infrastructure projects. Envision uses a sustainability approach that includes social, economic and environmental impacts. Envision will be a guide for owners or communities if they want to plan or implement infrastructure solutions.

The envision system has 4 planned stages or project reviews. For now, the ISI is receiving public comments on its website www.sustainableinfrastructure.org on the first two stages through the end of 2011.

 Stage 1 is a self-guided evaluation process. The user has to answer ‘yes’ or ‘no’ to a series of questions that guide the user through criteria. There are 10 primary criteria and 74 secondary criteria. They deal with the sustainable performance of smaller or single-purpose projects.  The main goal of this stage is to give the user a basic understanding of sustainability.

The user earns one or zero points depending on the answer to the questions. The maximum score for the Stage 1 assessment system is 104 points.

 The table below summarizes the 10 primary criteria for project review and their weight in total stage 2 score.

  Stage 2 provides a comprehensive assessment and recognition framework. This system allows an owner, engineer or other user to perform an assessment and to look for areas to improve or acknowledge the sustainable performance of a project. Stage 2 uses the same primary and secondary criteria as the Stage 1. The difference between these two stages is that Stage 2 awards points based on a weighted scale with a wider scoring range. This range recognizes higher levels of achievements that include improved, enhanced, superior, conserving and restorative. This rating system provides the users guidance documents as well to help them find the most applicable level of achievement for the project. The maximum score for Stage 2 is 1,000 points.

Stage 3 will more narrowly evaluate existing specific projects.

Stage 4 will focus on complex projects to determine optimum solutions, return investment and project delivery by balancing project features tradeoffs.

The ISI expects Stages 1 and 2 to be available for use on projects for the spring of 2012 and Stages 3 and 4 to become available after 2013. 

PROFESSIONAL ASSESSORS

Professional assessors have to follow a specific training provided by the ISI to learn how to use the envision system. Then they have to pass an exam to be able to perform assessment of Stage 2 projects.

The ISI will also collaborate with professional verifiers to review and confirm representations from owners and engineers. The ISI does not know yet how much it will cost to have projects verified but it will depend on project size and complexity and it will probably cost from $2,500 to $25,000.

        The envision system aims at being the North American ‘system of choice’ to rate the sustainability of infrastructure. Envision has plans for the future such as creating a formal awards system to award the projects with the highest level of sustainability as rated by the tool.
