Life cycle analysis (LCA) is a crucial tool for evaluating the environmental impacts of different pipe materials used in water supply systems. This analysis covers the entire life cycle of the pipes, from the extraction of raw materials to manufacturing, transportation, operation, and finally, their disposal or recycling at the end of their useful life….
Artificial cloud seeding is a form of weather modification that aims to enhance precipitation, dissipate fog, or suppress hail. This technology involves the dispersal of substances into the air that serve as cloud condensation or ice nuclei, altering the microphysical processes within the cloud. The concept, which has evolved significantly since its first successful experiments…
By Dr. Sabarna Roy, DI Business Head – Sales & Marketing, The Sandur Group The advantages and disadvantages of manufacturing ductile iron pipes as per ISO 2531 for water application and ISO 7186 for sewerage application, and whether harmonisation of Indian Standards is required in line with International Standards needs to be deliberated widely in…
By Dr Sabarna Roy, DI Business Head – Sales & Marketing, The Sandur Group INTRODUCTIONThe ability to manage an irrigation system is dependent on having an accurate estimate of the percentage of pumped water that becomes available for crop use.

Introduction Hydraulic thrust forces are created due to change of direction, reduction in diameter, and at the end of pipelines under pressure during operation, which may cause joint separation if anchor blocks or anchoring devices are not provided in the pipeline. One of the most common methods of providing resistance to thrust forces is the…
From day one, in India we did not integrate wastewater projects with water supply projects. The reason being: water is a service provided by the Government that is politically sensitive to win elections. The over-arching thought is: wastewater projects have no produce; it is only to be disposed of. With development of technology and acute…
Current irrigation challenges in India and the way forward It is known that 89 per cent of water in India is consumed for irrigation. Today, the major concern is the lack of sustainability of the water sector in India. The Indian government has adopted the path of self-sufficiency in food grains through irrigation by creating…
