Ecological sanitation will develop only when the government and industry see’s its potential benefit to society. The future of ecological sanitation lies in seeing its potential and investing further in its research, development and infrastructure. We cannot imagine the eco-san systems exist after 50-100yrs from now. With no doubt we can say that it will be much more sophisticated than now. But eco- san principles of containment, pathogen destruction and recycling of nutrients will remain…

• The water scarcity is caused by Indian action.

• The flows in the western… Continue

Impact of Climate change on flood sector has reviews such as

•  mapping flood prone areas using modern technologies like remote sensing, satellite data and air borne laser terrain mapping.
• flood plain zoning bill be adopted and enforced
• flood hazad zonation maps be prepared and widely publised
• flood forecasting and warning network be strengthened and modernised
• instrumentation for monitoring of glacial lakes and warning for outburst flood be…

Government of India will soon implement for e-waste management, they are planning to send a notice to all electronic manufacturing companies to collect the e-waste by putting up collection centre in certain places and reuse the waste product. The manufacturing companies should collect and reuse the product. E-waste includes computers, laptops, TV, refrigerator, washing machine, mixer and grinder, music systems etc. this would be the best E-waste management step taken by the government. should… Continue

Nowadays in opting appartments people opt for higher floor.. the cost of apparments also increases as the floor number increases. The construction companies have started building above 20floors with gated community. they say the higher the floor pollution free, but my point of view is higher the floor also the suspended particulate matters move upwards and take time to settle back to downward. my option of selection of floor would be below 3 and not above it. some opt for higher floor saying…

According to this, the molten plastic would be mixed with heated blue metal pieces and then mixed with bitumen. The molten plastic would form a thin layer over the metal binding the road strongly. This reduces the use of bitumen.

Global anti-incinerator alliance says, when roads degrade, the plastic which is non biodegradable will permeate the soil and pollute the ground water.

But this method is not been adopted anywhere. Will this be a good idea of disposing plastics?

Molten… Continue

CETP was promoted by MoEF in 1984 to treat wastewater from small and medium scale industries sector (SMIs). First CETP was constructed in1985 in Jeedimelta near Hyderabad. CETP was followed by other states in TN, MP, Gujarat, and Maharashtra.

A bulk environmental pollution is caused by SMIs. Small scale industries policy has no thought for environmental planning. For the effluent from SSIs the concept of CETP was introduced. The MoEF has instructed the SPCB to establish CETPs in…

• Recharges and formation of new aquifers because of increased incidents of floods

• Ground water with draw/during summer may decrease, however, during the winters; the demand of ground water will increase

• More surface water reservoirs will be required to harness flood waters and will lead to more recharge over longer period.

• Erosion activity will be more

• Evapo-transpiration losses shall be more especially in area where ground water levels are shallow.

• High… Continue

Rajasthan has resulted in a rapid depletion in ground water level and deterioration in water quality due to over exploitation. In Rajasthan, owing to meager surface water resource, ground water is only sources of dependence and survival, over 70% irrigation and 95% drinking water supply schemes are based on ground water resources. Availability of surface water is mainly restricted to canal command areas of Indira Gandhi Nahar Project, Chambal and Mahi rivers. To meet the demand, the…

India has been facing water stress and scarcity at various degrees at various places in the country. On the advent of climate change it is appropriate to take adoptative measures in all sectors particularly agriculture. Considering Water-Energy Nexus , it is necessary to evaluate water related equipments, machineries, utilities and even water supply schemes in total by arriving at their respective ‘Carbon Foot Prints’(CFP). This could be done for both existing schemes and newly proposed schemes… Continue

DEWATS are effective, reliable , cost efficient and custom-made wastewater treatment systems, which are perfectly suited for small to medium size systems(5-1000m3 /d) on community level and for individual users like institutions, hospitals or enterprises(SME). On community level ,DEWATS can be integrated into a sanitation complex, which is operated on pay and use basis, ccreating income opportunities for local personal. DEWATS solutions are not intended to replace but rather to… Continue

Coastal zones in India are currently facing increasing stresses and shocks as a consequence of cumulative environment change driven by population growth, urbanization, industrial development, trade and capital flows, liberalization of transnational corporation activity and life style, attitudinal changes and unsustainable growth leading to degradation of coastal zones and ecosystems.

A large percentage of coastal population is directly dependent on coastal and marine resources like… Continue

The ultimate goal in the design of a deep filter bed used in water treatment is to produce good quality of filtered water. The design parameters are not seen generally linked to the economic aspects of the filter beds. With the advent of dual media filters which produces about twice the quality of water than produced from conventional monomedia beds with equivalent water quality. the initial cost of the dual media filters are on the higher side when compared to the monomedia filters.A lower…

Climatic changes wont be smooth transition to a warmer world.Climate change elements fall into 3 categories:

• melting ice and permafrost.
• climate phenomena like EI Nino and the Gulf stream that influences other elements.
• changing rainfall patterns in the tropical and sub tropics.

Four sets of risks associated with these elements and the impacts:

• Sea level rise
• Unstable monsoon in India
• Drought in…
