Drinking water in disaster affected areas
The coastal area of Bangladesh is the biggest victim to climate change : SIDR,
AILA

3.  Coastal people suffer from
scarcity of drinking water
 People have to carry water
from far away, even 2-3 km
 Some families spend good
amount of money for water
The Core Problem

Solar Water Pumps (SWP)
 Project description: Water is pumped by using solar energy
to overhead tank, sent by gravitational force through
underground pipeline (2-6km) near to household clusters
(8-10 dispenser points). For surface water sources, a simple
pond sand filter is used for micro bacterial contamination
removal.
 Technology:
 Ground water: test and identify drinkability of water
source before pumping
 Surface water: purify in a four-stage filtering systems
 Salt water: Solar powered desalinization plant
(expensive!)

Solar Water Pumps (SWP)
 Scale of the Intervention: 122 installed Projects; 17 under
technical assistance with CDMP
 Beneficiary: 50,000+ households
 Outputs: Providing 1.9 million litres of safe drinking water
per day, ensuring hygiene and health among salinity affected
coastal belt
 Outcomes:
 Community livelihood improvement
 Income generation scopes
 Improvement of health
 Women empowerment
 Productive time enhancement
 Environmental sustainability: Water source conservation
and preservation

Management and Ownership
 The plants are owned by the Union Parishad (UP)
 Beneficiaries form management committees; UP and UNO from the local Govt. are
involved as committee members
 Management committees are involved in site selection, pipe line route, sites of
dispensers. Beneficiaries contribute in initial investment
 Management committees appoint caretaker for operation & maintenance
 Plant lifetime is 20 years; comes with 5 years free service.
 Beneficiaries pay 30-50 Taka per month, which is used for
 salary of caretakers
 maintenance of the plants
 Other business models are being tested:
 Leasing to local NGOs
 Leasing to private entrepreneurs

Gender impact of SWP
Issues Pre-project
scenario
Benefits from the intervention Outcome
Productive
time
Women with
children had to
walk 4-5hours to
collect safe
drinking water
from distant
sources
1. Dispenser points near to
households are reducing water
collection time
2. Saved times are now being used
in productive activities such as:
 Income generation
 Education
Livelihood
enhancement
Pregnancy
and
maternal
health
safety issues
Pregnant women
and mother of
infants had to
travel miles in their
final days of
pregnancy
1. Less pregnancy complications
2. Increased family time
3. Breast feeding and proper nursing
time
Improved
maternal and
child health.

Gender impact of SWP
Issues Pre-project scenario Benefits of intervention Outcome
Income
generation
Women had little /No
income
1. Remuneration of the
female dispenser manager
2. Income scope from water
refilling into the jars
Livelihood
enhancement
Empowerment
of the female
dispenser point
managers
Women are politically
marginalized in rural
coastal belt
1. Social recognition and
empowerment of rural women
2. Engagement of women in
decision making process
Women
empowerment
Health and
safety
Water Bourne
diseases, skin
diseases, salinity
induced health issues,
specially in children
1. Water lifted from 700-1000
feet deep boreholes are
usually bacterial
contamination free
2. PSF based systems treat
bacteria and other solid
impurities
3. RO systems eliminate
salinity, bacteria and other
Better health,
specially in
children

Challenges:
 Ownership issues
 Operation, maintenance and
management issues
 Economic viability for
scalability
 Local Government’s readiness
Learnings:
 Technology is ready, management
issue is the core challenge
 Local Government engagement is
a must for future scaling up
 Private party/NGO involvement
may be beneficial for business
model development
 The management system is
crucial for sustainability,
community mobilization issues
are vital
