management/ rainwater resource—
 Increased Water Pollution
 Old Water infrastructure development
 Irrational/ unrealistic-- pricing of fresh water.
 Inefficient/outdated technologies/ management of
 -- poor water sourcing ,--water delivery
 -large leakage, theft, wastage / unaccounted water.
 Focus on water supply- not on water management.
 Lack of accountability/transparency- consumption
 Irrational water norms/standards
 Inequal access to safe drinking water/ sanitation

Water-
Management

How Water can be
made available to
all- Nobody is left
without water

Why Conserve/Manage Water?
 Optimization of Finite Resource-The water source is finite;
 Promoting Equity--Water not equitably distributed
 Saving Energy--Water use impact-- energy required water
supply/hot water Conserving water saves money.
 Preventing Greenhouse gases-associated with treating / distributing water.
 Avoiding Overloading- municipal sewer systems
 Avoiding untreated sewage-- to flow to lakes / rivers.
 Preventing polluting - water in lakes/ rivers, / watersheds.
 Minimising waste water ,-- smaller network
 - Reduced cost of network
 Smaller sewerage– to be treated- less recurring life-cycle cost, less area, less
pollution, lesser discharge , lesser energy consumption
 Extend life of septic system-- by reducing soil saturation

Water Management
 Critical issue of water consumption
 - Water under threat- despite being central to life,
 -- demand on supplying aquifer/sources-
exceeding its ability to replenish itself
 Key objectives of water sustainability-
 i. Promote management, protection / restoration of
freshwater ecosystems
 ii. Improve- Water Quality
 iii. Optimise Consumption- Increase water
Efficiency- Reduce wastage
 iv Promote Equity-No body to left behind

SDG -6- Clean Water/Sanitation

Strategies for
Water Management

Managing Water-Physical Planning
 - Adopting Regional Planning approach-- for sourcing,
consumption/ conserving water for urban /rural India.
 Linking/integrating all human settlements-- with adjoining
peri-urban/ agricultural land, for meeting water demand for
urban /rural
 Making water conservation/ waste water management --
integral part of urban planning process
 Making cities Spongy -- promoting porosity/ open spaces
 -Planning cities/large complexes --making water
efficient/zero waste water
 Rationalizing landscaping --focus on minimizing use of
fresh water.
 --Using landscaping/ flora and fauna-- minimizing water
consumption.--Using local/native trees-

Managing Water-Physical Planning
 Promoting Retaining rather than Draining water
 -Linking all open spaces -with rain water harvesting .
 Identifying/Preserving/protecting/promoting/augmenting--
all existing water resources/draining systems .
 Identifying /promoting/protecting all existing areas-- of bio-
diversity
 Using all existing low-lying areas-- for creating manmade
water bodies/ lakes/ponds for storing water
 Preserving/ collecting/sourcing rain water;- for promoting
ground water recharging;
 Adopting Integrated approach- to rain water harvesting
 Creating more open spces in the city
 Identifying/preserving– all existing water resource

Managing Water- Management
 Making construction sector water- efficient- consuming
1/6th of global water
 Going for off-site construction/ modular construction
 Decentralizing - waste water collection/recycling at
community/neighborhood level
 Mandating all industries-- to be zero-waste water,
 - defining standards /norms for water consumption ,
 Making all Group Housing Societies/healthcare---- zero
water waste by incentivizing
 Eliminating single use -promoting multiple use of water-
at all levels of water consumption.
 Making rainwater harvesting-- integral part of building
construction/ building operation processes..
 Protecting fresh water resources /defining protected
green belts around them
 Producing water efficient- plumbing system/fixtures

Making Cities Spongy

supply/distribution/quality/leakage/misuse/consumption/abuse Using-
and mapping available sources of water
 Creating Awareness- role /Importance of water
 Involving --Communities / all stakeholders

Saving Water
 If human are the cause of problem– we humans can
only provide solution
 If we can cut back on amount of water we use every
day, we’ll be doing planet a big favor.
 Using water efficiently help-- preserve the environment,
 -minimize impact of droughts,
 - take some pressure off public water supply.
 also keeping some money in your pocket- by reducing
utility costs.
 Saving water requires small lifestyle changes—changing
few small habit - help making world a better place,
