It is most important that you follow these guidelines as closely as possible.Taipei is the political and economic center of Taiwan. It is inevitably required to hope for the best yet prepare for the worst regarding hazard mitigation. The nearby Sanchiao Fault, classified as a type II active fault by Central Geological Survey, MOEA, due to low activity, remains a major seismic concern to the City. Recently, new geological evidences indicate that its length might extend further to the off shore for quite a distance. As a result, its seismic hazard potential could be higher than previously expected. In view of this, Taipei Water Department (TWD) launched a research project to investigate the likely consequence to its pipeline network under a postulated M7.1 event triggered by the Sanchiao Fault. It was found through scenario simulation that ground failures in terms of both fault rupturing and soil liquefaction may contribute numerous pipe damages. The scale of disaster, i.e. the number and distribution of pipe damages including pipe breaks and leakages, was estimated. The manpower and materials required for the recovery of the pipeline network were examined. A comprehensive plan with countermeasures to confront such catastrophic situation was prepared.Furthermore, the seismic assessment of Yungfu Bridge, one of the four water pipe bridges that play pivotal roles in the functionality of TWD water system, was performed. Linear elastic static and dynamic analyses, nonlinear static pushover analyses, and nonlinear dynamic time history analyses were applied to examine its seismic capacity under various seismic conditions. It is proven capable of sustaining moderate seismic load without being inelastically deformed. However, according to nonlinear pushover analysis, its performance in longitudinal direction fails to meet the seismic demand for important bridges under design earthquakes, and should be retrofitted.[{"title":"Water Pipeline Network(pdf)","url":"https://www-ws.gov.taipei/001/Upload/public/Attachment/5781783674.pdf"}][][][]Taipei Water Department22034600https://english.water.gov.taipei/News_Content.aspx?n=5267D21DA27BA842&s=88F451F1BACEE53DAn Analysis of Water Pressure Affecting Metering Performance of Domestic Meters in TaipeiAbstractBy means of comparing historical meter readings with water pressure data, in a selected area, it revealed that when water network pressure rise by 0.5kg/cm2, the metering accuracy of domestic meters increase by 2.1% and along with household water consumption arise by 2.1%, the two rising components contribute 4.2% registered volumes of domestic meters. It is clear that metering performance grow due to pressure rising.Within the two components, on the one hand, the reason resulting in the increase of “metering accuracy” term is because the rising pressure generates higher flowrate which makes meters working in a much accurate condition. On the other hand, the increase of “consumption” term is because the rising pressure increases faucet’s discharge which causes higher household consumption, in other words, wastes of water.This research developed a practical method to identify the increase of ”metering accuracy” and “consumption” components from meter reading data, although its values are very small and hard to extract. Using a technique of Master-Sub meter grouping data analysis, it is easy to estimate the two components varying with its water pressure.[{"title":"Water Pressure (pdf)","url":"https://www-ws.gov.taipei/001/Upload/public/Attachment/568972781.pdf"}][][][]Taipei Water Department22034620https://english.water.gov.taipei/News_Content.aspx?n=5267D21DA27BA842&s=2D91BA8D2A328A27Mathematical Solution for Average Metering Error of Domestic Water Meters - a Relative Error MethodAs everyone knows that domestic water meters have metering errors which cause under registration in average. However almost no one can be sure what the figure is, because the metering error is affected by two complicated behaviors: water consumption of household, and the inaccuracy of meter itself. And it is hard to gain enough data for studying both of them.Actually, the two behaviors are already contained within historical meter readings. This research analyzed the meter readings and developed a practical approach to identify average metering error for water utilities. Using the RM－z μ chart with the equations comprising statistical parameters, Taipei Water Department (TWD) has successfully estimated average metering error in its 99.6% domestic meters, including Sub Meters (-9.85% in average, under registration), Master Meters (-6.11% in average, under registration) and Direct Meters (-10% in average, under registration). Due to TWD’s specific billing mechanism among Master Meters & Sub Meters, the equivalent metering error of Master-Sub meter groupings is only -4.26% in average. And its metering performance is better than any other non-grouping meters. Additionally, this method may provide an alternative way to estimate the Customer Meter Inaccuracies term in Water Balance Sheet.[{"title":"Mathematical Solution(pdf)","url":"https://www-ws.gov.taipei/001/Upload/public/Attachment/551111233315.pdf"}][][][]Taipei Water Department
