Deadly chemicals from detergents end up in rivers
India needs to come up with a regulation on use of toxic chemicals in detergents.

The sanitation crisis in India - An urgent need to look beyond toilet provision
Recent evidence indicates that India is heading towards a major sanitation crisis in the coming years. Efforts made at meeting the sanitation challenges have been found to have very limited results, with as high as 65% of the population not having toilet facilities coupled with very low use of existing toilets in urban and rural areas.
It is perhaps the right time to critically evaluate and move beyond the excessive focus we have on 'provision' and pay attention to the underlying complexities of the mechanisms involved, that influence sanitation behaviour among people. If we dont do so, we stand the risk of "missing all the trees for the forest", i.e. missing the social and economic dimensions of the sanitation needs of the people, in the hurry to count the number of toilets provided ! Aarti Kelkar-Khambete writes about the issue.

Toolkit for integrated urban water management, developed by Institute for Resource Analysis and Policy
This toolkit published by the Institute for Resource Analysis and Policy (IRAP) is an outcome of a study that involved exhaustive review of research undertaken all over the world on various aspects of urban water management by scholars and practitioners. It is not only relevant for water managers of urban local bodies, but also senior policy makers, scholars and practitioners concerned with water resources, particularly urban water.

Climate change and water sources: Strengthening community preparedness and water use regulations hold the key
Climate change is one of the most serious threats to the environment, health and economy of our nation as well as the whole world. Recent scientific studies show that global warming is already causing environmental changes that will have significant global economic and social impacts. As the world's 4th largest emitter of greenhouse gases, India has to juggle the imperative demand for economic development with pressures for greater efficiency in the use of energy.

Water law in a globalised world - Philippe Cullet discusses the need for creating a new framework
Water issues are rapidly acquiring a global dimension, while water laws remain rooted in specific regions. In this paper published in the Journal of Environmental Law, Philippe Cullet examines the need for a new framework for water law that allows for linkages with the global water cycle as well as human rights and environmental law.

1. Introduction
Draft National Water Policy (2012) fails to take into account the multiple, complex problems and issues relating to water in India says M S Vani
The Draft National Water Policy 2012 seems to be an improvement over earlier versions due to a fundamental shift from the ‘project oriented’ approach espoused so far by the bureaucracy and political establishment to a ‘resource’ oriented approach. Water, considered state property due to eminent domain principle, was hitherto seen only in terms of projects- irrigation or multipurpose. Now at least it is defined as a ‘natural resource’.
But what does it really mean, to call water as a ‘natural resource’? What is the relationship we as humans are seeking to establish with this part of nature? What are the relative roles of citizen and state in India towards this resource?

Perusing the draft, one comes across all the ‘right’ concepts, words liberally sprinkled throughout the document, describing the resource:-

  • Natural resource
  • Hydrological cycle
  • Ecological needs of rivers
  • Climate change
  • Sources pollution

and our intended response to it :-

Integrated water management for rural/urban India: Common effluent treatment plant can conserve fresh water in industrial estates
Contamination of surface and groundwater resources is rampant in rural/urban India with wastewater entering fresh water bodies or seeping into groundwater. An integrated approach is needed to manage the water and wastewater treatment so that water supply is kept clean and wastewater is recycled for beneficial use in agriculture and industry. This paper will present a study that was completed for the Hammond Sanitary District in Indiana where 38 million gallons per day (MGD) will be recycled after secondary treatment for beneficial use by land owners in Northwest Indiana.

National Environmental Engineering Research Institute seeks opinion from the public on the concept of groundwater recharge with treated municipal wastewater
The Ministry of Water Resources, Government of India, New Delhi, has entrusted National Environmental Engineering Research Institute (NEERI) to undertake a feasibility study on "Artificial groundwater recharge using treated municipal wastewater". Artificial groundwater recharge is a process of augmenting the natural purification processes occurring within the soil aquifer in the vadose zone. This treatment technique is known as Soil aquifer treatment (SAT).
