Water conservation by Industry – A case study of Mahindra and Mahindra, Zaheerabad
Posted on 30 Apr, 2010 11:07 AMThe presentation deals with Mahindra and Mahindra’s (M&M) work on optimal utilization of groundwater resources in its vehicle manufacturing plant at Zaheerabad, Andhra Pradesh. M&M had taken help from ICRISAT and Groundwater Department of GoAP to study the hydro-geology and topography of the estate and prepare ground water maps.
A time bound master plan of water augmentation was worked out to undertake activities like rainwater harvesting pits, new locations for borewells/ openwells/ percolation tanks, planting of less water intensive trees, re-usage and re-cycling of wastewater, rainwater channels to recharge the under ground water reservoirs and installation of drip irrigation.
Water conservation by Industry – A case study of ITC, Saharanpur
Posted on 29 Apr, 2010 12:41 PMThis presentation describes the work of ITC Saharanpur, a cigarette manufacturing company in the field of water conservation. Its water saving projects are centered around re-use of treated water for reducing water consumption, Effluent Treatment Plant (ETP) based effluent network system in residential areas, rainwater harvesting, installation of Cold Plasma Unit in place of wet scrubbers and installation of a jet spray system.
Rain water harvesting, recycling, reuse of waste water and using less water will help in water conservation, says Sekhar Raghavan, director of Rain Center, Chennai

Case studies on Water Management by Industry from the CII-GBC National Awards for Excellence in Water Management (2007)
Posted on 21 Apr, 2010 12:43 PM
The CII-GBC National Awards for Excellence in Water Management 2007 are an important step towards encouraging, supporting and applauding industry efforts to conserve water and reduce toxic effluent discharge. As India's economic boom gathers more and more momentum with each passing year, industrial water and energy use and related environmental impacts are going to be among the most critical factors in resource sustainability debates in the country and elsewhere. The companies portrayed represent a wide spectrum of industry: paper, metals, agro-processing, synthetic fibre, petroleum, transport, cement, energy, fertilizer, soft drinks and more.
Water Footprint Manual: State of the art - A method of water footprint assessment by the Water Footprint Network (November 2009)
Posted on 11 Apr, 2010 07:37 PMhe Water Footprint Manual, 2009 by the Water Footprint Network is a comprehensive and up-to-date outline of the method of water footprint assessment. It introduces
how water footprints can be calculated for individual processes and products, as well as for consumers, nations and businesses.
The concept is introduced as a comprehensive indicator of freshwater resources appropriation, as against the traditional and restricted measure of water withdrawal.
The hidden water use behind products are measured over the full supply chain and water consumption volumes are measured by source and polluted volumes by type of
pollution. All components of a total water footprint are specified geographically and temporally. Blue water (surface and groundwater), green water (rainwater stored
in the soil as soil moisture) and grey water (polluted water) footprints are defined and are included along with the indirect water use in measuring the overall water
footprints.
The core of the manual deals with the four distinct phases in water footprint assessment: (1) setting goals and scope; (2) water footprint accounting; (3) water
footprint sustainability assessment; (4) formulation of response. The goals and scope would vary for national governments, river basin authority, company etc. Water
footprint accounts give spatiotemporally explicit information on how water is appropriated for various human purposes. The manual articulates the need for clarity
about the inventory boundaries, about where to truncate the analysis, at what level of spatiotemporal explication and for which period of data when setting up a water
footprint account. It in addition deals with difficult questions like whether to include the water footprint of labour, transport or energy applied in a production
system in the assessment of the water footprint of the final product.
The manual then goes on to state the inventory boundaries of water footprint sustainability assessment. The sustainability of a water footprint is viewed upon from
different perspectives: the environmental, social and economic perspective. Besides, sustainability is measured at different levels: local (e.g. violation of local
environmental flow requirements), catchment or river basin level (e.g. contribution to the violation of environmental flow requirements downstream). In addition, the
water footprint of a product has implications beyond the level of a particular river basin. In the section on water footprint accounting the coherence between various
sorts of water footprint accounts is looked at. The manual presents complex equations explicating the water footprints due to processes and products and has sections
dealing with calculation of (a) green, blue and grey water footprint of growing a crop or tree (b) green and blue evapotranspiration using the CWR (Crop Water
Requirements) option in the FAO’s CROPWAT model (c) green and blue evapotranspiration using the ‘irrigation schedule option’ in the CROPWAT model. The manual also
presents the data sources for the calculating these.

An ecological framework for water management in a domestic context - A spreadsheet-based toolkit by Biome
Posted on 08 Apr, 2010 10:43 PMBased on user-entered data on domestic water demand, waste water discharge, rainfall availability and recharge, extent of reuse of treated waste water, this spreadsheet-based toolkit developed by Biome Solutions allows you to juggle around with the relevant data fields, and figure out various ways in which you can bring down your overall groundwater draft (and hence ecological footprint) as low as possible, and gives a snapshot result of your overall household-level water input and output situation.
