7:45 am Breakfast and Installation of Officers - Sapphire Ballroom – Diamond Ballroom, Larry Thomas, moderator9:00 am – Loss of Head Testing – Better Planning and Execution Results in Increased Accuracy and Less CostsStu Bowns, Group Manager and Ruch Rabold, Project Manager, Woolpert LLP. In distribution systems where there is flow of water through pipes under pressure, the Hazen-Williams Formula is most often used to relate velocity and head loss. The value "C", which is the Hazen-Williams Coefficient, varies with different pipes, but essentially is a function of the roughness of the pipe interior. Newer pipelines may have "C" values of 130 to over 140 while older mains that have been affected by tuburculation or deposits will have considerably lower "C" values. Although age of pipe is a factor, there are many other variables such as materials, construction, and treatment processes that may affect the "C". It is necessary that an accurate field-test, or "Loss of Head Test", be made by measuring the flow rate and head loss in an isolated section of pipe and then computing the actual "C" value from the formula. This paper will provide distribution system operators with first hand knowledge in the current technology of Loss of Head Testing based on current Ohio water system case studies. 9:30 am – Phosphates Beyond Corrosion Control Stu Bowns, Group Manager and Ruch Rabold, Project Manager, Woolpert LLP. Phosphates are well known for their corrosion control and sequestering capabilities. There are many more benefits to the use of phosphates in potable water systems, ranging from improved chlorination and reduced bacterial populations to an easier operating system, with fewer mechanical and replacement costs, lower maintenance costs, as well as overall better water quality. This presentation details these benefits, and it also includes case studies and photos of such benefits. If every water system, at its inception, injected a trace of these phosphates, water quality in these systems would remain stable, and the ever degrading distribution infrastructure would be in much better condition. 10:00 am – Automatic Leak Detection Finally Arrives Bud Reed, Director of Sales, Flow Metrix, Inc. Many government agencies are now contemplating adopting the newly proposed AWWA-IWA best practices for water loss control, including a new water audit methodology. This could mean new mandates for achieving lower levels of non-revenue water, and implementation of an active leakage control program. With involvement from the National Science Foundation, and input from a few utility partners, Flow Metrix (Maynard, MA, USA) has developed a low cost, "leak sensor" which can be embedded throughout a distribution system. The sensors perform an automatic, and continuous, leak survey, 24/7 – transparent to the traditional operation of the utility. And, because they can interface to most wireless AMR systems, or operate in a stand-alone mode, a comprehensive leak survey can be performed on-demand, but no less frequently than the meter reading cycle. This presentation will introduce the audience to this amazing new technology, and will also discuss its role in reducing Non Revenue Water due to leakage, and maintaining water losses at unprecedented low levels. 10:30 am – Break 10:45 am – Hydraulic Modeling, ISO Hydrant Flow Tests and Your Community’s Insurance Rates Stanley S. Diamond, P.E., Associate, Greeley and Hansen LLC. This presentation will show how the hydrant flow tests performed by the Insurance Service Office (ISO) can be used to identify where communities may need to deliver large volumes of water for emergency fire fighting, and how utilities can use that information with their hydraulic models to determine what additions and modifications need to be made to strengthen their delivery systems. In addition, this presentation will review how the ISO uses the hydrant flow test results as one of the parameters in rating communities for insurance purposes. Since those rates can impact insurance rates throughout the community for long periods, water utility managers and community leaders need to be aware of the flow testing and rating processes. This presentation will describe measures utility managers and community leaders can take to improve their distribution systems and potentially their community’s insurance rates. 11:15 am – Causes of Corrosion and Solutions for Water Piping
Systems 11:45 am – Initial Distribution System Evaluation (IDSE):The First Step Towards Complying With the Upcoming Stage 2 DBPR Dr. Kwok-Keung Au, Ph.D and John C. Vogel,P.E. Greeley and Hansen LLC. In accordance with the Stage 2 DBPR, utilities are required to conduct an Initial Distribution System Evaluation (IDSE) to study the DBP levels throughout their distribution system and thereby to identify monitoring locations that will represent peak DBP levels. The objectives of this presentation are 1) to provide a comprehensive review of the regulatory requirements associated with the IDSE, 2) to discuss the fundamentals of DBP formations within distribution systems and 3) to suggest several practical approaches to conducting IDSE. Water Quality – Ruby Ballroom, Arthur Sanders, moderator 9:00 am – Brine - The Residual of the Future Edmund A. Kobylinski, P.E., Gary Hunter, P.E., Scott Carr, P.E. Black and Veatch Corporation. This paper reviews the issues related to brine disposal at WTP’s and the available alternative methods, and presents the advantages and disadvantages of each. An opinion of the capital and operating costs for each alternative will be presented. 9:30 am – Human Tracers as Surrogate Indicators of Potential Septic Contamination of Potable Aquifers: A Decision Tool for Water and Wastewater Infrastructure Planning Sharon Waller, P.E. and Andrew Eaton, P.E. MWH Americas. High levels of nitrates in private wells has sparked a debate over urban growth patterns and past agricultural practices in Northern Indiana. Three sampling events over six years have provided data on coliforms and nitrates but have not produced a compelling case for local politicians to agree on future action. If nitrate concentrations are predominantly due to past agricultural practices, no change in development patterns may be warranted. If nitrates are due in part to high densities of on-site septic systems, urban planning modifications and major infrastructure development may be warranted. To provide further data, a human tracer pilot sampling program has been developed and preliminary data is presented for compounds, such as pesticides, herbicides, caffeine, acetaminophen and tobacco metabolites, that would indicate the presence of contamination from septic systems and/or agricultural practices. 10:00 am – Inactivation of Microcystin-LR by Free Chlorine in Drinking Water Treatment Benjamin Zeier, Water Project Engineer, Earth Tech, Inc. Microcystin-LR, a cyanotoxin, has been identified in source and treated drinking waters in the U.S. and Canada. Health effects caused by microcystin-LR include the possibility of increased risk of carcinogenesis and tumor promotion in the liver, which led to the World Health Organization provisional drinking water guideline of 1 µg/L. Chlorine is used by more than 95% of the medium and large water utilities in the U.S. and as a result would be easily accessible if CT values were developed for chlorination of microcystin-LR. This presentation focuses on the background of microcystin-LR and the initial research conducted at the University of Wisconsin at Madison to determine the CT values needed for chlorine inactivation of microcystin-LR. 10:30 am – Break 10:45 am – My Sample Failed QC – Did I Do Something Wrong?
