  • Sustainability | waterid.org
    Sustainability Sustainability Definition One of the early definitions of sustainable development was Development that meet the needs of the present without compromising the ability of future generations to meet their own needs Brundtland 1987 The understanding of sustainability has evolved significantly which is reflected in refined definitions that integrate environmental economic social and even organizational considerations The integration of these aspects allows the application of sustainability principles in the daily operation of civil infrastructure systems In summary Sustainability refers to the ability of a given system to perform indefinitely in a dynamic equilibrium with its context Traditionally engineering was focused only on the technical dimension of civil infrastructure The belief was that any problem could be solved by analyzing the system in pieces and understanding how the pieces work and fit together like a clock However systems are more than the sum of their parts and by taking apart those systems we lose information and ignore essential relationships and feedbacks Sustainable engineering requires a more holistic system approach where changes in one part may have unintended effects on other parts of the system and therefore the system needs to be addressed as a whole Image courtesy of U S National

  • Condition Assessment | waterid.org
    water and wastewater utility managers and others have access to current and relevant information on condition assessment technologies and practices so that resources such as time and money can be utilized most effectively Pipeline Condition Assessment Technologies Utilities must use their limited funding in an optimal way to repair rehabilitate and replace pipes When data associated with the condition of pipe is insufficient or unavailable then utility managers cannot make sound asset management decisions leading to an increased risk of failure increased operations and maintenance costs and higher life cycle costs for the pipe infrastructure Obtaining such data is more challenging than for other infrastructure assets because pipes are mostly buried and generally inaccessible Variations in pipe properties and external conditions in a collection wastewater or distribution drinking water system further complicate the development of a comprehensive asset management system Technology Product and Service Providers information Water type Any Drinking Water Wastewater Drinking Water and Wastewater CA technology class Any Acoustic Electrical or Electromagnetic Flow Testing Gyroscope Inclinometer Physical Testing Pressure Testing Temperature Testing Vibrational Technology Visual Technology Other SOLO Superior Smoke Generators LeakFinderRT Pipe Diver Kalsi Eng Flow Testing STI CMCP420VT Loop Powered Vibration Transmitter PANORAMO SpirALL Magnetic Flux

  • Subsurface Utility Engineering | waterid.org
    1980s Traditional methods of dealing with subsurface utilities were not working It was common practice to design projects without consideration of any utilities and to then deal with them during construction This resulted in many unnecessary utility relocations construction delays and unexpected encounters with subsurface utilities It seemed possible that two relatively new technologies air vacuum excavation and surface geophysics could be combined to gather data on the exact location of subsurface utilities early in the development of projects Source Paul Scott 2005 SUE Then and Now Presented at Damage Prevention Conference Dallas Texas Pipeline Locating Technologies Sub surface Utility Engineering SUE identifies locates maps and analyzes a range of information to accurately ascertain the location of buried pipes Since most pipes are buried and generally inaccessible planning for renewal activities is extremely difficult Any differences in as planned and as built location of pipes can cause accidental damage to pipes by third parties Damage to underground utilities has been identified as one of the most dangerous problems for the construction industry and the American Institute of Constructors AIC identified damage to underground utilities as the third most important problem for contractors Accurately locating pipes will ensure more confident planning

  • Financial Information | waterid.org
    utility managers face ever increasing challenges in adequately sustaining the aging supply and distribution infrastructure As resources become scarce careful enlightened decision making is required to maintain current water quality levels as the pipe systems deteriorate at an overwhelming rate It is of great value to the members of the water and wastewater utility industry to know how they compare with similar members based on location size and public private configuration in the evaluation of key financial metrics These metrics include financial ratios rate structure and the inherent revenues rate trends and return on investment and cost benefit ratios of system assessment and renewal initiatives Financial Information Sources While not all financial information for water and wastewater utilities is readily available a vast amount of them post their yearly financial reports on the web Also thousands of bid tabs and the related documentation are available on the web involving condition assessment and renewal engineering The collection and analysis of these and similar data sources coupled with the engagement of utilities to capture the triple bottom line costs of projects regarding condition assessment and renewal engineering will create invaluable intellectual knowledge for the industry and embolden the asset managers in making
