This link on the Central Public Health and Environmental Engineering Organisation (CPHEEO) website, presents data related to the status of the urban water, sanitation and solid waste management in India. The data includes information on:

  • Status of water supply (physical)
  • Status of urban water supply (financial)
  • Status of urban sewerage/sanitation system
  • Status of low cost sanitation
  • Status of solid waste management

Data is included from different states in India namely Assam, Arunachal Pradesh, Karnataka, Gujarat, Maharashtra, Mizoram, Pondicherry, Sikkim and Tamilnadu respectively.

Deaths due to water pollution
Safe water is a far-longed dream in this country. Everyday thousands are consumed by diseases caused by contaminated water Posted on 02 Aug, 2010 02:38 PM

Deaths due to water pollution occur mainly as a consequence of drinking of contaminated water. The common diseases caused by consumption of contaminated water are Cholera, Viral Hepatitis, Enteric Fever (Typhoid) and Acute Diarrhoeal Diseases (ADD).
 
The number of deaths reported State-wise on account of Cholera, Viral Hepatitis, Enteric Fever (Typhoid) and Acute Diarrhoeal Diseases (ADD) for the years 2007, 2008 and 2009 are given in      Annexure – I-III.  

National Rural Drinking Water Programme - Framework for implementation - MoRD (2010)
The Rural WaterSupply enters its fourth phase with emphasis on ensuring sustainability water with a decentralised approach Posted on 02 Aug, 2010 01:46 AM

The Government of India launched the Accelerated Rural Water Supply Programme (ARWSP) in 1972-73 to ensure provision of adequate drinking water supply to the rural community through the Public Health Engineering System.

The second generation programme started with the launching of Technology Mission in 1986-87, renamed in 1991-92 as Rajiv Gandhi National Drinking Water Mission. Stress on water quality, appropriate technology intervention, human resource development support and other related activities were introduced in the rural water supply sector.

The third generation programme started in 1999-2000 when sector reform projects evolved to involve community in planning, implementation and management of drinking water related schemes, later scaled up as Swajaldhara in 2002.

The Rural Water Supply (RWS) sector has now entered the fourth phase with major emphasis on ensuring sustainability of water availability in terms of potability, adequacy, convenience, affordability and equity while also adopting decentralized approach involving PRIs and community organizations.

Tank study in Belgaum district of Karnataka– A research report by National Institute of Hydrology
The report presents a study of the Rakaskop tank, which caters to the drinking and domestic water purposes of the Belgaum city of Karnataka. Posted on 27 Jul, 2010 08:30 PM

The report presents a study of the Rakaskop tank, which caters to the drinking and domestic water purposes of the Belgaum city of Karnataka. In recent past, it has been observed that the amount of water stored during the monsoon season is not sufficient for domestic purposes in the city throughout the year. The study estimates the dependable yield of the tank and also the evaporation from the tank.

Project Boond - V, a comprehensive mitigation initiative in the drought prone regions of Bharatpur
Water scarcity in Rajasthan as monsoons fail and Bilaspur- dam dries up Posted on 21 Jul, 2010 01:47 PM

With the failure of monsoons in Rajasthan and dry-up of the Bilaspur dam, the water situation assumes graver proportions in most parts of Rajasthan, besides Jaipur, Tonk and adjacent districts. These areas, now in the news for acute water shortage problems, have always depended upon monsoons for their traditional rainwater-harvesting systems and the riverine sources.

While the Government has taken remedial measures with construction of tube-wells across the rural and drought-prone areas, they have been sporadic and insufficient at their best.  Merely announcing relief measures and planning of schemes on paper as an immediate disaster management strategy are not solutions to mitigation of water problems in this State.

Estimation of runoff from Bewas basin using SCS Curve Number method - A research report by National Institute of Hydrology
In the study, SCS-CN method is used to predict runoff volume from the Bewas basin at a dam site meant to augment municipal drinking water supply to Sagar city. Posted on 29 Jun, 2010 10:10 AM

In the study, Soil Conservation Services Curve Number (SCS-CN) method is used to predict runoff volume from the Bewas basin at a dam site meant to augment municipal drinking water supply to Sagar city. The SCS-CN model involves relationship between land use, land cover, hydrologic soil class, and runoff Curve Number of hydrologic soil cover complex, which in turn is a function of soil type, land cover and antecedent moisture condition.

Capacity evaluation of Bhakra reservoir using digital analysis of satellite data - A research report by National Institute of Hydrology
The study assesses sedimentation rate, water spread area and volume of the Bhakra reservoir in Satluj basin using remote sensing data for the years 1988-89 and 1996-97. Posted on 23 Jun, 2010 10:48 PM

The study assesses sedimentation rate, water spread area and volume of the Bhakra reservoir in Satluj basin using remote sensing data of IRS-1B satellite and LISS-II sensor data of the years 1988-89 and 1996-97. The original elevation-area capacity curves and the reservoir levels on the eight dates of pass of the satellite were obtained from the Bhakra Beas Management Board, Nangal.

Using the trapezoidal formula, the capacity in between the maximum (513.904 m) and minimum (450.436 m) observed levels was assessed for the year 1996-97. The loss of capacity till 1988-89 was 491.315 mcum and till 1996-97 was 807.354 mcum. These could be attributed to the sediment deposition in the zone of study of reservoir.

Performance evaluation of percolation ponds for artificial recharge - A research report by National Institute of Hydrology
The study assesses the quantum of seepage to the aquifers through two percolation ponds in Tamil Nadu and assesses the total storage loss in the pond. Posted on 23 Jun, 2010 07:39 PM

The study assesses the quantum of seepage to the aquifers through percolation ponds and establishes their zone of influence, and based on these, correlates the quantum of seepage to the total storage loss in the pond. The assessment of the benefits of the ponds, in terms of artificial recharge to the aquifers is done through an intensive study of two percolation ponds in Tamil Nadu.

A percolation pond is a small water harvesting structure, constructed across a natural stream or water course to harvest and impound the runoff from the catchments for a longer time, to facilitate vertical and lateral percolation of impounded water into the soil substrata, thereby recharging groundwater storage in the zone of influence of the pond.

Piped water supply to Greater Bangalore: Putting the cart before the horse – An EPW special article
The paper critically evaluates the GWSAP which aims at extending piped water supply from the Cauvery to over two million residents in peri-urban Bangalore. Posted on 09 May, 2010 06:47 AM

The paper critically evaluates the Greater Bangalore Water and Sanitation Project (GWSAP), implemented by the Bangalore Water Supply and Sewerage Board (BWSSB). This project aims to extend piped water supply from the Cauvery to over two million residents in peri-urban Bangalore. This ambitious project has been viewed against the backdrop of the broader trends and debates around market-based reforms in the water sector in Karnataka.
