Manual on sewage and sewerage treatment - CPHEEO (MoUD)
Dealing with the sanitation of the country with the increasing urbanisation and population. Posted on 15 Sep, 2010 11:07 PM

This manual has been prepared by the Central Public Health and Environmental Engineering Organisation (CPHEEO), a department under the Ministry of Urban Development (MoUD) and aims at meeting the professional needs of practising engineers dealing with the sanitation sector in the country, that focuses on achieving the goal of 'sanitation for all' within a reasonable timeframe.

The manual  is a revised version of the earlier one, which was developed in 1977 and was widely used by field engineers engaged in sewerage and sewage treatment. However, a need was felt to revise and update the earlier manual taking into consideration the advancement in technology.

Allocation of water charges for multi-housing communities in India: Sub-metering and ratio utility billing system (RUBS)
A deliberate competition insinuates among water users as the demand for water increases along with its overuse. All key lies in allocation, reuse and recharge. Posted on 10 Sep, 2010 01:35 PM

 One of the most serious issues of water management is the question how to allocate the water resources to guarantee sufficient amount of water for all demands. That is why, it can be expected that allocation management will gain further importance in the future. It is not exaggerated to declare that “the issue of allocation overshadows all other aspects of water management”.

Water quality status of historical Gundolav lake - Kishangarh - South Asian Journal of Tourism and Heritage
Urbanisation and population explosion has moved Gundolav from a freshwater lake to a wastewater drainage Posted on 25 Aug, 2010 09:44 AM

Gundolav Lake RajasthanThis paper published in the South Asian Journal of Tourism and Heritage describes the water quality status of Gundolav Lake in Rajasthan, which was once used for drinking water as well as for recreational activities under the tutelage of the princely state of Kishangarh. This has now become a site of wastewater disposal and facing a critical threat for its sustenance. 

Recent years have led to an increasing awareness of the importance of water bodies and  the need for conservation of water bodies, especially freshwater wetlands. The Ramsar Convention (2002) identifies wetlands as the starting point for integrated water management strategies. This is because they are the source of fresh water, maintain the health of the water course and water bodies, have the capacity to supply water to meet the human needs and are a key to future water security.
