WATER USAGE
Only 20 per cent of the water is used for drinking, cooking;
Over 60 per cent is used for bathing, washing and flushingdown the toilet. Important that our water toilets are still 10-12 litres per each pull of the chain.
Literally, water down the drain
...80% potable water ends up as waste-water
GREEN BUILDING CONSULTANCY SERVICESGREEN BUILDING CONSULTANCY SERVICES
IN COMMERCIAL BUILDINGSq Major Water consumers are
n Plumbing (Flow / Flush Fixtures)
n HVAC
n Landscaping
q Thus efficient use of water can lower water use fees, lowersewage volumes to treat etc. and thus lower capacitycharges and limits
q Technologies are available to treat gray water, harvest rain
water and use treated water for landscaping / flushing etc.
q Potential to reduce water consumption upto 30%
