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.,

• The plugging & clogging of filter and
• Wash out microbes from the reactor        

This manual has been developed by the Central Public Health and Environmental Engineering Organisation (CPHEEO), a department under the Ministry of Urban Development (MoUD) and  serves as a standard guide in public health engineering by providing a code of day to day practice for public health engineers to follow.

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.

This link on the CAG website provides the details of an international conference that was held on 15-16 March 2010, in the backdrop of the environmental audit proposed by the the Comptroller and Auditor General (CAG) of India, for management and conservation of the environment .

The purpose of this conference was to deliberate on the causes of pollution, action taken by governments and civil society to address this and environmental, management and legal interventions needed to put lakes, rivers and ground water on the path of sustainability.

More than 20 experts on water and water pollution issues were invited to share their views as panelists during the conference. Apart from these distinguished panelists, the heads of supreme audit institutions from countries like Austria, Maldives, Bangladesh and Bhutan were also present to share their experiences regarding audit of water pollution in their countries.

 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”.

Description:

The Consortium for DEWATS Dissemination (CDD) Society is a not-for-profit organisation working in the field of decentralised basic need services across India. Decentralised solutions for waste water treatment, water and energy supply, solid waste management and urban sanitation planning are successfully promoted for the past ten years.

This 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.

The paper by Challenge Programme on Water and Food (CPWF) attempts to assess and improve water productivity in conservation agriculture systems in the Indus-Gangetic basin, in which during the past 40 years an intricate mosaic of interactions between man & nature, poverty & prosperity and problems & possibilities has emerged. Rapid expansion in agricultural water use is a common theme across these interactions and access to water is central to the livelihoods of the rural poor.
