Major factors considered to design this PSF operated by Solar?Major factors considered to design this PSF operated by Solar?
Ensure continuous flow in the PSFs.
Encourage bio-sand filter.
Mechanized Solar pump for ensuring continuous flow.
Introduced double action lift pumps in case of
. Introduced sensor to prevent overflow and ensure
continuous flow.
Introduced lighting system at the night by solar thuspromote protection.
Considered pond protection

Introduced mechanizedpumping system forcontinuous flow.
PSF cost was almost
2,20,000BDT excluding pondrenovation.
Solar system cost was 1,61,000BDT

Major lessons learnt from the ProjectsMajor lessons learnt from the Projects
General & For Solar system:
Activation of WMC after phase out of the project.
Accountability and transparency of the management committee.
After phase out, relevant stakeholders responsiveness.
ene c ar es are sa s e .
Environmentally friendly as contributing nothing to global warming
The efficiency of the solar system also varies on the season and location of
the sun.
Solar system design could be little bit higher than the requirements.
In many cases, Solar system providers dont have any local office.

More effective for bacteria removal due to biological activities.
Easy operation & maintenance
PSFs are expected to be long term functional.
No laborious manually pumping
Establishment cost of the PSF with solar s stem is com arativel hi h but

covering more people.
Availability of pond water throughout the whole year especially in the dry
season. Lack of advocacy initiatives for protection (Saline intrusion, Shrimp culture)
of the sweet water pond in the coastal reasons

Way ForwardWay Forward
Reduction of the cost may be explored for scaling up the technologies
DPHE could take lead to replicate the interventions.
Step forward to encourage private sectors to establish Regional/local solar
service providers.
Initiate to preserve sweet water pond at Arsenic and Saline contaminated
areas. DPHE could take lead role to motivate the Land ministry and other
relevant ministries.
Aware policy makers regarding solar technology to provide scope in the
investment plan.
