Training modules on planning, development and management of groundwater with special reference to watershed management programmes by ACWADAM
A comprehensive training module on basic hydro-geology and groundwater science Posted on 06 Oct, 2010 08:12 PM

Acwadam

Advanced Center for Water Resources Development and Management (ACWADAM) is a premier education and research institution and facilitates work on groundwater management through action research programmes and trainings. ACWADAM’s main thrust has been on the process of capacity building and facilitation, both founded strongly on its research base.

ACWADAM, with support from the Ford Foundation, has embarked on strengthening civil society capabilities in groundwater management, using the watershed management platform. A comprehensive training module on basic hydrogeology and groundwater science, has been developed, and can be sourced by writing to ACWADAM at acwadam@vsnl.net.

These trainings enable the trainees particularly from Civil Society Organisations to improve the planning, implementation and monitoring of their watershed development and allied projects.

Multi stage aerobic bio reactor for sewage treatment
AN attempt to overcome the problem of clogging and wash out of microbes from reactor, and to enhance the mixing and settlability of microbial granules within the reactor, Posted on 01 Oct, 2010 10:13 PM

About CAT “MAR” (Multi Stage Aerobic Bio Reactor)

This reactor was developed with the aim to overcome the main problem associated with SBR, MBR & FABBR, i.e.,

  • Wash out microbes from the reactor        
Analysis of the UN General Assembly's Resolution on Right to Water and Sanitation
Why historic UN General Assembly Resolution declaring Water and Sanitation as a Right, was opposed and vetoed by those who strongly have been professing for human rights Posted on 30 Sep, 2010 06:47 PM

The historic UN General Assembly Resolution declaring Water and Sanitation as a Right, was passed on the 28th July 2010. 

What is surprising is the complete silence to this UN Resolution from some of the countries who have been traditional champions of human rights, in terms of celebrating it as a historic achievement in advocating a basic right to water and sanitation. Instead some of them went one step short of openly opposing and vetoing the UN Resolution and have heaped criticism on Bolivia for tabling this UN Resolution.

Protect the right to life considering the dignity of women who do not have access to a toilet
How Mumbai tackles its situation of sanitation and water: finds out Jan Jagruti Posted on 30 Sep, 2010 10:26 AM

Sanitation - a big problem in India, as half the population of our country do not have access to this facility. Mumbai is one of the biggest cities in the world and advanced in terms of its commercialization. However, sanitation is one of the most common issues neglected. Our team of women from Jan Jagruti went into the lanes of 3 areas Azad Mohala, Bharatiya Kamla Nagar, Vijay Nagar and spoke to women to understand the severity of the sanitation issue prevailing. These areas have severe problems with public health, due to improper sanitation infrastructure and insufficiency of toilet facilities, compounded by numerous issues of flooding during the monsoon season. Khaaddi, a local area/dumping ground, is widely used by local residents for urination and defecation, leading to the spread of contagious diseases. Though women use paid toilets, the issue of cleanliness and waiting in long queues are the most common problem before them. It is very insecure for them when they use open spaces for defecation.

Water Resources Engineering and Management - A Civil Engineering Course under the National Programme on Technology Enhanced Learning
A web-based course to enhance the quality of engineering education in the country Posted on 29 Sep, 2010 07:42 AM

This Civil Engineering Course under the National Programme on Technology Enhanced Learning (NPTEL) on the broad subject of Water Resources Engineering and Management is being carried out by Indian Institute of Technology’s and the Indian Institute of Science, Bangalore as a collaborative project supported by the Ministry of Human Resource Development (Government of India) to enhance the quality of engineering education in the country, by developing curriculum based video and web courses. In these web based lectures, the authors have developed the subject in detail and in stages in a student-friendly manner. The broad group of Water Resources Engineering is structured into modules on the topic by IIT Kharagpur as follows:

Successful innovations in solid waste management systems: Examples from five local bodies in Tamil Nadu
This booklet illustrates examples of the implementation and impact of solid waste management innovations in five localities in Tamil Nadu Posted on 28 Sep, 2010 11:32 AM

Innovations in Solid Waste Management Systems - Tamil NaduThis booklet about the work of Exnora Green Pammal (EGP), produced by UNICEF and published by the Government of Tamil Nadu,  illustrates examples of the implementation and impact of solid waste management innovations in five localities in Tamil Nadu. The solid waste management systems in these localities are widely regarded as successes that deserve replication.This document has been produced to inspire and enable more local body authorities to emulate such successes in other parts of the country.

Improving solid waste management services in India is an urgent challenge for all levels of the government. Littering and the indiscriminate disposal of solid waste are widely practiced, polluting India's air, water, soil and inhabitants. Such pollution impedes India's efforts to achieve the Millennium Development Goals (MDG).The nation's measures to combat malaria and other diseases (MDG 6), reduce child mortality (MDG 4), and ensure environmental sustainability (MDG 7) are all hampered by the unsightly and unhygienic conditions created by the accumulation of waste.

India’s groundwater typologies – A presentation by ACWADAM
Groundwater typologies in India Posted on 22 Sep, 2010 08:01 AM

This presentation by ACWADAM deals with groundwater typologies in India. The typology of groundwater can be defined in many ways based on a) Uses of Groundwater, b) Geography, c) Geology, d) Hydrogeology (Aquifers), e) Groundwater Quality, f) Stage of Groundwater Development, and g) Socio-ecology of Groundwater.

Chemistry of groundwater – A presentation by ACWADAM
Quality of water is quintessential. Quality of groundwater supply determines where and for what it can be used. Posted on 21 Sep, 2010 10:40 PM

This presentation by ACWADAM deals with the chemistry of groundwater. It is now recognized that the quality of groundwater is as important as its quantity. All groundwater contains salts in solution which are derived from the location and the movement of water through rocks. The quality of groundwater supply depends where and for what it is planned to be used. Thus water quality standards for drinking water, industrial water and irrigation water differ significantly.
