In this study, water samples collected from various ground water sources (bore wells, open wells etc) and surface water (rivers, lakes, etc) and treated water in urban and rural areas and analysed for its nitrate contents. Over 500 samples were analysed for nitrate contents so as to find out the source of contamination and the mechanism of its formation in waters.

Unlike before water distribution is becoming a crucial part of resource management. The debate is mainly revolving around high cost and limited quantity. Public, private and NGO initiatives are reeling under same critical problem. There is no model exist to ensure equal access to water.

Water hyacinth growing in the lakes absorbs the nutrients (phosphorous, nitrogen) being released to the lake water from untreated sewage discharged in the lake, for their growth and reduces the nutrient concentration in the lake water. After a period of time these plants sink to the bottom of lakebed and decay affecting water quality.

Basic water supply is crucial to effectively address the challenges of both urban and rural development. Municipal authorities/state governments in developing nations are especially hard pressed to design, develop and finance the basic urban services such as safe and reliable water supply.

An urban drainage system conveys storm water from the upstream to the drainage point in the towns and cities. The most important task of this system is to keep the streets and buildings from flooding.

This paper aims towards the development of the framework for domestic rooftop harvesting for drinking water. The paper is based on the analysis of survey record of around 50 houses of different rooftop areas of peri-urban area of Dhule city.

Contamination of groundwater by arsenic and its adverse effect on human being have been reported in 20 countries in different parts of the world. Groundwater arsenic contamination has raised its ugly head recently in Assam. Arsenic concentration in groundwater samples from the three blocks viz.

In the present study, an attempt has been made to evaluate the treatability of a combined tannery and domestic wastewater using lab-scale activated sludge reactor under extended aeration.

Statistical and probability analysis of rainfall occurrences of Nayagarh block of Orissa was carried out for planning and designing of water conservation and recharge structures.

During disaster, management of essential services is a daunting task. Water supply systems (WSS) are susceptible to natural disasters like earthquakes, floods and famine and also face threat from man-made disasters. Since water is the basic need of living being, restoring it is a major challenge to water engineers in such a scenarios.
