Reports from the Water Research Foundationā€ƒ Phase 3: Decision and Scheduling In this phase, decisions are made for each pipe-whether to schedule its replacement or alternatively schedule the next inspection. RESULTS/CONCLUSIONS Several elements of the approach have been demonstrated using data obtained from Portland, Oregon. A homogeneous pipe was defined and relevant cost data as well as expert opinion from Portland about the likelihood of segment survival were used to compute the pipe semi-informative remaining life. Subsequently, historical failure data were used, in conjunction with a prescribed Bayesian updating process, to update the initial (semi-informative) assessment of the remaining life of the pipe. Subsequent analysis answered the following questions: * At what age should Portland start to regularly inspect the pipe? * What is the impact of inspection on the pipe remaining life? * What inspection technology should Portland use for this pipe and how should it be budgeted? Many of the elements in this approach are already implemented by various water utilities in some form. The proposed approach provides a theoretical foundation as a basis for a solid framework, where field data, fortified by expert experience, are used to develop a rational decision process that is supported by the best available information. The mathematical foundation is fully developed, not overly complex, and relatively easy to implement in an Excel spreadsheet. With a relatively modest effort, it can also be developed into a standalone application or a decision engine that can be embedded into an existing asset management database system. APPLICATIONS/RECOMMENDATIONS As stated above, this project was developed as a manual, which can be readily adopted by any water utility in part or in full. Although all the elements of the approach can be implemented in Excel spreadsheets with relative ease, a dedicated software program might render the approach more accessible to water utilities that do not have the resources to develop an in-house application. RESEARCH PARTNER National Research Council Canada Nitrate and Arsenic Removal From Drinking Water With a Fixed-Bed Bioreactor [Project #4293] ORDER NUMBER: 4293 DATE AVAILABLE: December 2014 PRINCIPAL INVESTIGATORS: Lutgarde Raskin, Kim F. Hayes, Jess C. Brown, Giridhar Upadhyaya, Tara M. Clancy, and Kathryn V. Snyder OBJECTIVES The research team developed a fixed-bed biologically active carbon (BAC) system to simultaneously remove arsenic and nitrate from drinking water sources. Removal mechanisms were elucidated through the use of microbial community analyses and solids characterization techniques. A variety of operating conditions were evaluated and optimized at the bench-scale level, keeping in mind the future goals of demonstrating this technology at pilot-scale and its eventual integration in full-scale drinking water treatment schemes. BACKGROUND Contamination of natural water sources with multiple contaminants, including arsenic and nitrate, has been a major concern in the context of providing safe drinking water throughout the world. There is a need for new technologies capable of removing these contaminants simultaneously. In past studies, fixed-bed BAC bioreactor systems have been demonstrated to successfully remove the oxy-anionic contaminants nitrate and perchlorate at the lab-, pilot-, and full-scale levels.
