Non-potable Water Quality Assessment Methodology for Water Conservation in Arid Climates

Microbial water quality risks to public health: potable water assessment for a flood-affected town in northern Pakistan.

INTRODUCTION In mid-July 2010 flash flooding in Pakistan destroyed the basic water, environmental sanitation and livelihood infrastructures in 82 districts. Two months later, the local press of Swat (northern Pakistan) reported that several residents of Marghazar town became ill and were hospitalized after drinking contaminated water. A non-governmental organization (Oxfam GB) team took action ...

Potable Water Savings by Using Rainwater for Non-Potable Uses in Houses

Abstract: The objective of this study is to assess the potential for potable water savings by using rainwater as well as the sizing of rainwater tanks in houses in some cities in the world. Daily rainfall data for thirteen cities located in different countries were used. Different catchment areas, number of residents, potable and rainwater demands were considered in order to assess their impact...

Portable LED fluorescence instrumentation for the rapid assessment of potable water quality.

Characterising the organic and microbial matrix of water are key issues in ensuring a safe potable water supply. Current techniques only confirm water quality retrospectively via laboratory analysis of discrete samples. Whilst such analysis is required for regulatory purposes, it would be highly beneficial to monitor water quality in-situ in real time, enabling rapid water quality assessment an...
