1. WATER MANAGEMENT SYSTEM WATER SAFE SUSTAINABLE AND FOR ALL A PRESENTATION BY: ANUJ BHAJANKA AVINASH CHIRANIA GUWAHATI COLLEGE OF ARCHITECTURE

3. THE SITE GUWAHATI COLLEGE OF ARCHITECTURE An Architectural Institute With Self Sufficient Water System Would Serve As A Living Example For The Masses To Be Aware Of And Adopt These Practices. People Look Towards Architecture To Serve Them With Better Living Standard….

5. 10 Resident @ 135 Lts/day/head 320 Students +40 Staff @ 45 Lts/day/head Watering Plants @ 100 Lts/day Car Wash @ 200 Lts/day Daily Consumption 17850 Ltrs. Annual Consumption 3527850 Ltrs.* PRESENT WATER CONSUMPTION 1350 Lts/Day 16200 Lts/Day 200 Lts/Day 100 Lts/Day * CONSIDERING 201 WORKING DAYS

6. BIFERCATION OF DAILY WATER USAGE FLUSH BATHING DRINKING WASHING UTENSILS COOKING WASHING CLOTHS => 40 LTRS => 4 LTRS => 3 LTRS => 20 LTRS => 25 LTRS => 20 LTRS INSTITUTIONAL USAGE RESIDENTIAL USAGE TOTAL USAGE 135Lts. TOTAL USAGE 45Lts.

7. CONCEPT “ WATER MANAGEMENT DOESN’T MEAN RESTRICTING THE USE,BUT REDUCING THE WATSE………” IDENTIFYING THE WASTE.. FRESH WATER USED FOR FLUSHING “ DOES IT MATTER WHAT KIND OF WATER IS USED FOR FLUSHING….” DISCHARGE OF RAIN WATER AND GREY WATER TO DRAIN. “ IF WE LOSE A DROP OF WATER EVERY SECOND, IT AMOUNTS TO ABOUT 10000 Ltrs. OF LOST WATER IN A YEAR…..”

8. EcoTrap inserted in the urinal outlet. This combination trap seal blocks out sewer gases, and blocks out urine odors from the room. NO FLUSH URINAL No-Flush urinals resemble conventional fixtures. The urinal bowl surfaces are 99% urine repellent. Daily cleaning procedures are the same as flushed urinals.

12. RAIN WATER HARVESTING 2500MM ANNUAL RAINFALL OVERHEAD TANK 66000 ltrs MICRO HYDRO ELECTRIC PUMP EXISTING UNDERGROUND RESERVOIR 125000 ltrs SLOPE ROOFTOP RUNOFF 70% OF (329 X 2500) = 575750 LTRS SURFACE RUNOFF 70% OF(301 X 2500) = 526750 LTRS OVERFLOW WATER TO THE GROUND CATHCHMENT AREA 329 SQ.M PERCOLATION PIT SANDBED FILTER OPEN SURFACE AREA 301 SQ.M WATER IS PUSHED BACK IN THE PIPE WHEN THE TANK IS FULL, THIS OVER FLOW IS DIRECTED TO THE PERCOLATION PIT. GROUND WATER RECHARGE ANNUAL RAIN WATER AVAILABLE- = 575750 + 526750 = 1102500 LTRS ANNUAL FRESH WATER REQUIRED = 613050 LTRS 489450 LTRS IN EXCESS

13. DEEP WELL BORING DEEP WELL BORING FOUNTAIN FOR AERATION TO UNDERGROUND RESERVOIR PUMP DURING DRY DAYS i.e. FROM THE MONTH OF NOVEMBER TO JANUARY WATER DEMAND CAN BE MET BY THE EXISTING DEEP WELL BORE. THE FOUNTAIN…THOUGH AN ARCHITECTURAL ELEMENT IT NOT ONLY ADDS TO AESTHETICS BUT ALSO HAS A FUNCTIONALITY… IT REDUCES THE IRON CONTENT BY OXIDIZING FERRIC TO FERROUS… FILTER BED

14. SCHEMATIC DIAGRAM OVERHEAD TANK RECYCLED WASTE WATER TANK W.C./URINAL BATH / WASH KITHCEN EXISTING UNDERGROUND RESERVOIR SOIL PIPE TWO WAY VALVE SEPTIC TANK TANK FOR COLLECTING GREY WATER DEEP WELL BORING BLACK WATER RAIN WATER PIPE

15. BLACK WATER HARVESTING 11100 liters of BLACK WATER is generated every 6 days…… This water is rich in urea content, nitrogen, phosphorous…… IS WASTING SO MUCH WATER INTO THE DRAIN A INTELLIGENT THOUGHT…….. WATSE WATER TANK TAKEN UNDER GROUND THROUGH AGRICULTURE PIPES TO THE SOIL IN THE ROAD DIVIDER CONTRIBUTING TO PUBLIC --------------- RELEASED UNDER GRAVITY ROAD

16. AGRICULTURE PIPE LIME BAGS UREA RICH WATER NOURISHES THE PLANTS These pipe avoid contamination of ground water. BLACK WATER UTILIZATION

17. 33% water can be saved without effecting normal life, just by reducing wastage… Use Bucket Instead Of Running Water For Car Wash Watering Plants During Morning Or Evening Save Water Loss Due To Evaporation. Low Flow Shower Heads Maximizes Water Coverage & Minimizes Water Volume A Bottle Of Mineral Water In The Cistern Controls The Amount Of Water Being Flushed At One Go. Kitchen Activities Should Be Planned To Reduce Wastage Of Fuel And Water Use Mug Instead Of Running Water While Brushing Run Dishwasher, Washing Machine And Dryer Only When Fully Loaded HABITUAL PRACTICES
