This presentation by ACWADAM on earth system deals with the interactions between the four elements that make up this system. The complexity of the earth system, in which spatial and temporal variability exists on a range of scales, requires that an organized scientific approach be developed for addressing the complex, interdisciplinary problems that exist.

The presentation by ACWADAM on earth system deals with the four elements that make up this system. Earth science generally recognizes four spheres, the lithosphere, the hydrosphere, the atmosphere, and the biosphere; these correspond to rocks, water, air, and life. These four interdependent parts or the earth's spheres are described as:

• the lithosphere, which contains all of the cold, hard, solid rock of the planet's crust (surface), the hot semi-solid rock that lies underneath the crust, the hot liquid rock near the center of the planet, and the solid iron core (center) of the planet
• the hydrosphere, which contains all of the planet's solid, liquid, and gaseous water,
• the atmosphere, which contains all of the planet's air, and
• the biosphere, which contains all of the planet's living organisms.

This presentation by ACWADAM deals with hydrologic properties of the rock framework in which groundwater occurs and through which it moves. In watershed programmes, it is necessary to develop a correct understanding of the storage and transmission of water within such channels because the shape of openings in a rock or sediment, their size, volume and interconnection play a vital part in the hydraulic characteristics of an aquifer.

This presentation by ACWADAM deals with introducing groundwater management protocols for wells in different phases of groundwater use. These protocols include geo-hydrology in watershed development, protection of recharge areas, efficient well use, pump capacity regulation, distance with respect to drinking water well regulation, depth regulation in drinking water well, regulation of agricultural water use and groundwater management through sharing.

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 manual has been developed by the Central Public Health and Environmental Engineering Organisation (CPHEEO), a department under the Ministry of Urban Development (MoUD) and is intended primarily for the managers and technicians in-charge of the O & M of the urban drinking water supply systems.

The aim of the manual is to serve as a guide for strengthening the technical, operational and managerial capabilities required of the concerned personnel to operate and maintain water supply services as per acceptable norms of quantity, quality, sustainability, reliability and cost.

This manual has been developed by the Central Public Health and Environmental Engineering Organisation (CPHEEO), a department under the Ministry of Urban Development and aims at assisting the policy & decision makers, planners, managers and technical personnel involved in solid waste management activities, in safe and hygienic handling & disposal of municipal solid waste generated in the urban areas in India.
