The operational water footprints is again divided into two components as operational water footprint directly associated with production of products and overhead operational water footprint. A considerable fraction of water returns to blue water resources after waste water treatment process therefore only consumptive water use of the blue water footprint is considered in the estimation of water footprint of production of products. The overhead</span><span style="font-size: 14pt; line-height: 90%;"> operational water footprint is </span><span style="font-size: 14.0pt; line-height: 90%;">the water consumption and pollution related to general water using activities including water use in bathroom and kitchen, watering the garden and washing the worker’s clothes within the business.<o:p></o:p></span></div> <div class="MsoNormal"> <span style="font-family: "times new roman" , "serif"; font-size: 14.0pt; line-height: 107%;"> The <b>supply chain water footprint</b> is </span><span style="font-family: "times new roman" , serif; font-size: 14pt; line-height: 107%;">the volume of freshwater consumed or polluted to produce all the inputs of production of the business. Thereby water footprint of one business can be overlapped with water footprint of another business through the supply chain. The supply chain water footprint is also again divided into water footprint related to products inputs and overhead supply chain water footprint. Overhead supply-chain water footprint</span><span style="font-family: "times new roman" , "serif"; font-size: 14.0pt; line-height: 107%;"> </span><span style="font-family: "times new roman" , serif; font-size: 14pt; line-height: 107%;">is the volume of water consumed or polluted due to the materials and energy for general use including cars, trucks, fuels, electricity.</span><span style="font-family: "times new roman" , "serif"; font-size: 14.0pt; line-height: 107%;"><o:p></o:p></span></div> <div class="MsoNormal"> <span style="font-family: "times new roman" , "serif"; font-size: 14.0pt; line-height: 107%;">Supply chain water footprint is larger than operational water footprint of many business which does not have own agricultural activities to produce their input since production of feed for animals requires much water than operating the processing industry including cleaning, washing equipment and pollution . The supply chain water footprint is dominated by green water while the operational water footprint is dominated by blue and gray water.<o:p></o:p></span></div> <div class="MsoNormal"> <br /></div> <div class="MsoNormal"> <b><span style="font-family: "times new roman" , "serif"; font-size: 14.0pt; line-height: 107%;">Water footprint of a person<o:p></o:p></span></b></div> <div class="MsoNormal" style="line-height: normal; margin-bottom: .0001pt; margin-bottom: 0in; mso-layout-grid-align: none; text-autospace: none;"> <span style="font-family: "times new roman" , serif; font-size: 14pt;">The water footprint of a person is the total volume of freshwater consume or polluted to produce all the good and services. According to the recent researches, nearly 4 % of the water footprint of humanity relates to water use at home (Hoekstra and Mekonnen </span><span style="color: blue; font-family: "times new roman" , "serif"; font-size: 14.0pt;">2012</span><span style="font-family: "times new roman" , serif; font-size: 14pt;">). <o:p></o:p></span></div> <div class="MsoNormal"> <span style="font-family: "times new roman" , "serif"; font-size: 14.0pt; line-height: 107%;">Water footprint of a consumer is divided into two components including direct use and indirect use. Direct use refers to the water use at home. It includes the drinking, bathing, cooking and washing at home. Number water units consumed per month is used to calculate the direct water use. The water footprint regarding consumed goods and services is considered as the indirect water use. Multiplication of number unit consumed from each good and services by their respective water footprint is summed to estimate the indirect water use.<o:p></o:p></span></div> <div class="MsoNormal"> <br /></div> <div class="MsoNormal"> <b><u><span style="font-family: "times new roman" , "serif"; font-size: 14.0pt; line-height: 107%;">Reduction of water footprint:<o:p></o:p></span></u></b></div> <div class="MsoNormal"> <b><span style="font-family: "times new roman" , "serif"; font-size: 14.0pt; line-height: 107%;">Industry</span></b><span style="font-family: "times new roman" , "serif"; font-size: 14.0pt; line-height: 107%;">: water meters should be installed to monitor the water use. Water audits should be conducted to identify the leaks and fix them as soon as possible. Raw materials with low water footprint should be used for manufacturing goods and services rather than raw materials with intensive water footprint. As an example, sugar cane cultivation requires more water than beet cultivation. Water results from the evaporation from beet can be used for the operations within the sugar manufacturing industries. Thereby it eliminates total water requirements from blue water resources including ground water and surface water. Therefore use of beet as raw materials can reduce the total water footprint along the both operational and supply chain of sugar manufacturing industry. Rain water harvesting system can be installed to store the rain water. These rainwater can be incorporated into boilers, condensers, cleaning the factory floors and flushing the toilets to reduce the use of portable water within the factories. Waste water treatment plant should be constructed or existing waste water treatment plant should be further improved to enhance the quality of the treated water. These treated water can be used for cleaning purposes and boilers of the factories. The pressure of the water distribution system can be reduced to decrease the volume of water delivered for particular purpose. Regular taps should be replaced by sensor taps to prevent leakages. Dual flush system should be installed for the toilets system rather water intensive single flush system. Dual flush system has separate flushing for feces with high water requirement and urine with less water requirement. The volume of the tank of toilet tank can be reduced by using a displacement device such as bottle filled with water.<o:p></o:p></span></div> <div class="MsoNormal"> <br /></div> <div class="MsoListParagraph" style="line-height: 150%; mso-list: l0 level1 lfo1; tab-stops: list .5in; text-align: justify; text-indent: -.25in;"> <span style="font-size: 14.0pt; line-height: 150%; mso-fareast-font-family: "Times New Roman"; mso-fareast-theme-font: minor-fareast; mso-font-kerning: 12.0pt;"><span style="font-family: "times new roman" , "serif"; font-size: 14.0pt; line-height: 107%;"> </span></span></div> <div class="MsoNormal"> <b><span style="font-family: "times new roman" , "serif"; font-size: 14.0pt; line-height: 107%;">Personal: </span></b><span style="font-family: "times new roman" , "serif"; font-size: 14.0pt; line-height: 107%;">Good and services with large water footprint should be purchased rather than goods and services with small water footprint. Products associated with beef meet requires more water than products associated with chicken meet because the cultivation of feed for cattle often consumes more water. Water saving techniques including sensor taps, faucet aerators, dual flushing systems and rain water harvesting systems can be implemented.

Leaks should be identified and fixed. Spills should be avoided as much as possible. Although people can reduce the negative impacts related to direct water use, it is difficult to reduce the negative consequences of indirect water footprint.<o:p></o:p></span></div> <br />
