Privatisation of urban water supply in Khandwa, Madhya Pradesh - An update from Manthan Adyayan Kendra
Khandwa is a medium-sized town located in western Madhya Pradesh. The 'Khandwa water supply augmentation project' has been awarded to Vishwa Utilities Pvt. Ltd., a Hyderabad based company under the Urban Infrastructure Development Scheme for Small and Medium Towns (UIDSSMT) on a Public-Private Partnership (PPP) basis for water supply augmentation to the town, for the next 25 years. The project has been under execution since October 2009. The private party would supply water to the town @ Rs 11.95 per KL. The raw water for this would be pumped from a reservoir 51 km, away from the town. This report by Gaurav Dwivedi and Rehmat, Manthan Adhyayan Kendra deals with the privatisation of urban water supply in the town.

Treating waste water using natural substances: Sol gel immobilization of humic and fulvic acids using microfibrillated cellulose
Microfibrillated nanocellulose has large pore sizes (100 to 1000 nm) and provides a large surface area of contact with surroundings. When manufactured by acid hydrolysis of substrate i.e. wastes from wine and sugar industry by acetobacter xylinum, it is lignin free and has a more intricate structure. (nanocellulose obtained as water suspension).

Humic acids and fulvic acids - Sol gel immobilization

Humic acids and fulvic acids have been known to remove heavy metals, toxins, viruses and other inorganic matter and convert them to organic matter. These acids can be obtained from dried cowdung by mild alkaline treatment and filtration.

Precious Kaveri water down the drain; wasted to wash vehicles: Letter to the Chairman, Bangalore Water Supply and Sewerage Board
I tried sending a suggestion to Bangalore Water Supply and Sewerage Board (BWSSB) to tackle the urgent crisis in Karnataka this hot summer but didn't get any reply. Water crisis is a serious issue. When people do not have water to irrigate their lands, to drink for themselves, it pains me in the heart to see people wasting water profusely to wash their vehicles which goes down the drain. Manjunath M P presents the letter he sent to the Chairman, BWSSB.

National Environmental Engineering Research Institute seeks opinion from the public on the concept of groundwater recharge with treated municipal wastewater
The Ministry of Water Resources, Government of India, New Delhi, has entrusted National Environmental Engineering Research Institute (NEERI) to undertake a feasibility study on "Artificial groundwater recharge using treated municipal wastewater". Artificial groundwater recharge is a process of augmenting the natural purification processes occurring within the soil aquifer in the vadose zone. This treatment technique is known as Soil aquifer treatment (SAT).
