Why am I Here?

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

Augmenting water availabilityWater quality challengesMore crop per drop agricultureWastewater managementDesalinationUncertainties and Calamities Management Water quality monitoring and surveillance

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

FO PLANT, OMAN

Hydration Bag

Geo-synthetic textilesTrenchless TsClimate-resilient CropsImmersion vibratory roller compactor concreteRadar to detect groundwater and contamination

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
