Driving Smarter WASH Interventions Across Rural Bangladesh

PKSF is one of Bangladesh’s leading development institutions, working to improve the socioeconomic well-being of rural communities. Through large-scale programs in microfinance, livelihoods, WASH, and human capital development, PKSF partners with government agencies and donor organizations to deliver sustainable impact nationwide.

Streams Tech developed a comprehensive GIS/GPS-based Monitoring & Evaluation (M&E) system for PKSF’s Bangladesh Rural Water, Sanitation and Hygiene for Human Capital Development (HCD) project—funded by the International Development Association (IDA) and the Asian Infrastructure Investment Bank (AIIB). 
The digital platform enables PKSF and its Partner Organizations (POs) to collect, validate, analyze, and visualize real-time WASH data across 78 upazilas, ensuring transparency, accountability, and evidence-based decision-making. 

The project aims to expand access to improved water and sanitation facilities while promoting healthy hygiene behaviors and strengthening human capital in rural Bangladesh. 
Operating across four divisions—Mymensingh, Rangpur, Chattogram, and Sylhet, the program supports: 

• Water facility upgrades 
• Sanitation loans and infrastructure 
• Hygiene and behavior change campaigns 
• Local entrepreneurship development 

The initiative benefits over 4.7 million people and directly advances SDG 6.1 and 6.2. 

The project is structured around three key focus areas: 

1. WASH Access & Infrastructure 

• 60,000+ water facility upgrades 
• 500,000 households installing twin-pit latrines 
• Geo-tagged mapping of handwashing stations, bathing units, and drainage works 

2. Health & Hygiene Behavior Change 

• Community-level BCC campaigns 
• Tracking hygiene practices including handwashing and menstrual hygiene 
• Session logs and household visit tracking for outreach verification 

3. Economic Empowerment & Gender Inclusion 

• 4,000 local entrepreneurs supported (masons, plumbers, WASH service providers) 
• 150 women-led menstrual hygiene businesses strengthened

The BD Rural WASH project demonstrates significant progress: 

• Reach: 4.7 million+ beneficiaries across 78 upazilas 
• Infrastructure: 500,000+ sanitation interventions monitored in real time 
• Entrepreneurship: 4,000 Local Entrepreneurs trained in WASH services 
• Hygiene Adoption: Improved handwashing, sanitation, and MHM practices 
• Data Systems: Real-time dashboards for all implementing levels 
• Accountability: Two-tier validation and audit trails for data integrity

Before digital transformation, PKSF faced: 

• Fragmented manual data collection across thousands of field points 
• Limited visibility of WASH activities across remote regions 
• A need for accurate geo-tagged verification of water and sanitation facilities 
• Inconsistent reporting formats across Partner Organizations 
• Limited connectivity in rural locations delaying data submission 

Streams Tech developed a cloud-based, modular platform tailored to PKSF’s operational needs. 

System Architecture 

• Web-based dashboard for PKSF, DPHE, and Partner Organizations 
• Android mobile app with offline data collection and sync 
• Role-based access control for admins, supervisors, enumerators 
• GIS-enabled visualization using Google Maps API and GeoServer 

Monitoring & Reporting 

• Survey modules for all WASH activities, verification tasks, and member profiles 
• Automated data approval workflows (two-tier validation) 
• Real-time dashboards with drill-down by division, upazila, PO, and indicator 
• Indicator Performance Tracking Table (IPTT) to measure impact 

Data Synchronization 

• Offline-first mobile app with background sync 
• Secure cloud hosting with HTTPS & SSL 
• Automated Excel/CSV import modules 
• API integration with MIS and PO data systems 

Learning & Feedback 

• Embedded feedback loops for enumerators and supervisors 
• Visual analytics for gaps, trends, and high-need areas 
• Eight large-scale trainings and multiple ToTs delivered across the country 
• Over 300+ personnel trained per session

• WASH facility coverage 
• Sanitation loan progress 
• Behavior change session reach 
• Verification of water and toilet standards 
• Entrepreneur engagement and training 
• Geo-tagged infrastructure mapping 

• Frontend: Angular, JavaScript, Bootstrap 
• Backend: Java (Spring Boot), PostgreSQL + PostGIS 
• Mobile: Android (with offline sync) 
• GIS: Google Maps API, GeoServer 
• Cloud: Secure hosting with HTTPS & SSL 
• Integration: REST APIs
