  • Asset Management Condition Assessment for Stockton: To Test or Not To Test

    ABSTRACTTo help ensure assets are maintained to high standards, a 20-year service contact between the City of Stockton and OMI/Thames Water required a condition assessment of all managed assets. Due to the size and complexity of the system, it was not possible to test all assets as part of the condition assessment. A methodology was developed to prioritize assets to be subjected to further ...

  • Analysis of water level changes in Lake Urmia based on data characteristics and non-parametric test

    Lake Urmia water level has fluctuated during many years. We investigated water level data (annual maximum, minimum and average series in the period of 1966–2012) to evaluate changes based on long-term and seasonal patterns over time, data characteristics and temporal change analysis. Our tools for the mentioned analyses included seasonal trend decomposition using loess (STL); normality and ...

  • Comparison and verification of four field-based microbiological tests: H2S test, Easygel®, Colilert®, Petrifilm™

    The UN defines water supplies as ‘improved’ or ‘unimproved.’ These indicators are easy to measure, but do not reflect water quality, which requires laboratory or field tests. Laboratory and test availability, expense and technical capacity are obstacles for developing countries.This research compares and verifies four low-cost, field-based microbiological tests: the EC-Kit (Colilert® and ...
