Water, water everywhereNor any drop to drink- Samuel Taylor
Assured and Fit for Purpose water supply by 2035
VISION
Ensuring quantity and quality of water in all
rivers andaquatic bodies
Grand challenge 2/10

WATERY FACTS
Water, water, everywhereNor any drop to drink- Taylor
Smart Leak DetectionBetter Cooling Towers and BoilersTreatment Ts-Biomimetic and Novel materials-CNT, graphene, FOZero Discharge- R&R TsHarnessing Atmospheric moistureSeismic tomography for rock rigidity
11 FUTURE Ts
Superstrong one atom thick graphene membrane is porous and needs less pressure to push water through it
GRAPHENE MEMBRANES
CNT immobilization in hydrophobic membrane pores favorably alters water−membrane interactions
Inspired by the mangrove plant and human kidney, biomimetic membrane is mechanically stronger and allows only water molecules to pass through
FORWARD OSMOSIS

FUTURE Ts
Non contact level sensors for riversWater meter without plumbingSeawater agriculture-seaweedsMicrobial fuel cell in wastewaterNet water positive materialsNextgen RO membranesHydrofacturing during floods
FUTURE RESEARCH
Ground water – social property and not individual assetPriority drinking, cooking and domestic – min 50 lpd per capita, desirable 100 lpd – max 150 lpdLeast amount of transportation – local sources and local distribution networkingFiltering and solar purificationRecycling. Grey water purified and used for toiletsBlack water for fertigationWater harvesting and ground water rechargeAfforestation of all sloppy areas
