SDG 6 AT A GLANCE
Focuses primarily on sustainable
management of water and avaibility of
safe drinking water for all
Statistical concerns it focuses on lowering:
• 2.2 billion people with no access to safely
managed water (UN 2022)
• 3.5 billion people with no access to proper
sanitation (UN 2022)
• 2.5 billion people in water-stressed countries
(UN 2020)
PRACTICAL SOLUTIONS 1
IMPROVING WATER TREATMENT & USAGE
We can focus on improving water treatment process and minimizing wastage to largely
increase access to safe drinking water in water-stressed areas.
Some processes that can aid us in these are:
Implementing AI in Water Treatment Plants
• Helps ease need of manpower in ETP, hence aid in decreasing the overall cost by reducing
labour fees.
• Can be used to check BOD and COD of effluents realtime and make proper errorless
judgements.
• Can be used for maintenance, where AI reports back any damaged parts, such as the
clarifier rotor is stuck from debris in the treatment plant is instantly detected and quickly
fixed.
• Helps make instant adjustments and increase efficiency
PRACTICAL SOLUTIONS 1
IMPROVING WATER TREATMENT & USAGE
Using Toilet to Tap Technology
• Collecting wastewater from different sources for instance household or industries
• These waters has to go through advanced treatment process for example: UV ray treatment or
reverse osmosis
This creates a cost effective solution for water scarcity. It also aids in reducing the price of
drinking water.
Using Toilet to Tap Technology
CITY-WIDE PIPELINES CAN WASTE HUNDREDS OF LITERS OF WATER A DAY JUST DUE TO
UNDETECTED SMALL LEAKAGES.
• Drone has sensors which can swiftly detect the leakage and chances of pipes bursting.
• Traditional leakage detection consis of checking pipes that stretches for hundreds of
kilometers and may days.
This heavily reduces labor costs and time consumption.

IMPROVING WATER TREATMENT & USAGE
PRACTICAL SOLUTIONS 2
COOPERATE WITH GOVERNMENT
We can focus on establishing cooperation with government to aid us in various plans and
installments and hence reduce chances of conflict with the law and to make attaining our
SDG goals more easier
Installing Water ATM’s
• We can install small water ATMs on rural areas, but these takes land and land
takes governments cooperation.
• This helps us efficiently reduce the lack of access of water in water-stressed
rural areas and slums in urban areas.
• Examples - Sarvajal cooperated with
governemnt and successfully installed hundreds
of water ATM’s in rural areas and saved lives
with drought occurred.
PRACTICAL SOLUTIONS 2
COOPERATE WITH GOVERNMENT
Installing ground water pumps
• We can cooperate with government in order to install groundwater pumps to
rural areas.
• Example: RFL cooperates with Bangladesh Government and provides tubewell and access to
free drinking water to 50+ families
PRACTICAL SOLUTIONS 2
COOPERATE WITH GOVERNMENT
Develop Solar-Powered Desalinators
• NGO’s and concerned organisations can cooperate with government to install
solar-powered desalinators to provide access to clean water in coastal arid
areas such as Cox Bazaar.
• Bangladesh Government already have
plans of installing zero-duty Solar Powered
Desalination plants
• This will be especially effective at tackling
the lack of clean water for Rohingya refugees
PRACTICAL SOLUTIONS 3
COOPERATE WITH ENTREPRENEURS AND INVESTORS
Encouraging them into water-entrepreneurship programs
• Collaborate with companies to invest in water-entrepreneurship programs
that will benefit both them in impact returns and the people.
• Involves corporations to brainstorm better water sanitation methods and
distribution of clean water in their business model
• Best example is FreeWater, a successful Texas
based startup.
• The water bottle ‘pays for itself’ by ad revenue
from the ads displayed on its label.
• This means people can just recieve this clean
drinking water for free, or at least, no monetary
costs.
PRACTICAL SOLUTIONS 3
COOPERATE WITH ENTREPRENEURS AND INVESTORS
Encourage Businesses into CSR activities
• We can let them know the positive impacts and benefits of CSR activities in terms of
impact returns and brand image improvement
• This means companies gets to promote their end and sustainable development
goals are also met.
• For example, Energypac’s CSR activities in Khulna helped save 200+ families who are suffering
from water salinity and scarcity.
• More giant corporations like Cocacola, Pepsico, BAT are also investing in clean water oriented
CSR activities
PRACTICAL SOLUTIONS 3
COOPERATE WITH ENTREPRENEURS AND INVESTORS
Promoting Sustainable Water Practices within Supply Chains
• We can convince MNCs and other corporations on the benefits of practicing
water sustainable methods in their supply chain.
• This will benefit both them by reducing overall production cost, and help
meet SDG 6 goals.
• For example, Nestle decided to minimize
unneccessary water usage on their factories to get
AWS certified.
PRACTICAL SOLUTIONS 4
INVESTING MORE IN INNOVATION
Research more efficient methods of solar-powered desalination method
• Hard to deploy the current desalination plant models on coastal areas since they are
very huge and expensive.
• More researching can help bring out more efficient and compact models that can be
deployed more easily and in a mass scale
• Innovative companies like Nevron Project are
constantly trying to making newer models of solar
powered desalinators more compact
PRACTICAL SOLUTIONS 4
INVESTING MORE IN INNOVATION
Researching mobile water treatment-units
• There are instances where access to water is present, the problem is that they are
wastewater or stagnant water that aren’t safe to drink. There is also no ETP plants aroung
the area such as in rural areas.
• The solution to these are coming up with water treatment units that are smaller, compact
and easier to deploy. Allowing more access to fresh water.
• Example: Portable water treatment units by UN & Power4All being deployed in areas with wastewater and no
treatment options
PRACTICAL SOLUTIONS 4
INVESTING MORE IN INNOVATION
Researching Cloud-Seeding Technologies.
• With current technology, we can artificially change cloud conditions to cause rainfall in
drought struck land. The problem is that its a very difficulty and complex process.
• Further research can help similar result at higher ease
• Example: Colarado River that was drying up is being replenished of its water content by cloud seeding by USAF.
PRACTICAL SOLUTIONS 5
IMPLEMENT WATER-CAPTURING TECHNOLOGY
Usage of Fog-Collectors in Rural Forests
• Many rural areas are dependant on tubewell for water, but during drought, its an issue. For
this we can use fog collectors that collect water droplents in mesh and collect it.
• Example: Used in Chile a lot, where communities in desert can harvest around 500, 000 liters of water per day!
PRACTICAL SOLUTIONS 5
IMPLEMENT WATER-CAPTURING TECHNOLOGY
Promoting Green-Roof construction
• Involves construction roofs of urban houses in such a way that it grows vegetation and
also uses the grounds filtration to collect debris-free rainwater.
• Some designs also seeps excess water back to groound water, hence helps groundwater
reservoices stay filled.
PRACTICAL SOLUTIONS 5
IMPLEMENT WATER-CAPTURING TECHNOLOGY
Install Borehole-Recharge systems in Urban areas
• Urban areas lack less open soil that seeps rainwater and filters and stores them as ground
water
• Borehole recharge systems are collection method where the rainwater is directly filtered and
transported to deep groundwater aquifiers. There it is stored and can be used as clean
drinking water to slums and other areas with contaminated water.
• Example: African water-stressed regions. The
people are benefiting from borehole recharge
systems.
THANK YOU!
Overall these 5 processes helps meet
various targets of SDG 6
Such as water use efficiency, reduction of water stress, access to
clean water, sustainable management of water resources and
water quality & ecosystem protection.
THANK YOU!
