  • Water Quality Models

    ' In order to determine the impacts of a particular discharge on ambient water quality, it is usually necessary to model the diffusion and dispersion of the discharge in the relevant water body. The approach applies both to new discharges and to upgrading of existing sources. This note provides guidance on models that may be applicable in the context of typical Bank projects.' Introduction ...

  • Water Quality in South Asia

    Abstract:There are significant differences in the water chemistry of the Himalayan and southern peninsular rivers. Large and small rivers also show different types of water quality. Liquid and solid waste definitely contribute to water quality in urban centres such as Delhi and even coastal regions, as near Mumbai, are affected by waste discharges. The sub-continent also suffers from problems ...


  • Status and trends of water quality in the Tafna catchment: a comparative study using water quality indices

    Water quality indices (WQIs) are necessary for resolving lengthy, multi-parameter, water analysis reports into single digit scores; different WQIs have been developed worldwide which are greatly differing in terms of mathematical structures, the numbers and types of variables included, etc. The aim of this paper is to evaluate trends of water quality in Tafna basin with a comparison of 10 WQIs ...

  • Bacteriological water quality compliance and root cause analysis: an industry case study

    Drinking water in England and Wales exhibits high compliance with quality regulations. Severn Trent Water (STW) rarely experiences quality failures, yet approximately half of those that do occur are for bacteriological parameters. There were 218 bacteriological non-compliances across the STW region between January 2008 and December 2011. Thirty nine percent of these were from water treatment ...
