Background:
The Centre for Microfinance and Livelihood (CML), an Associate Organisation of Tata Trusts, has been implementing a Water Quality and Security Programme (WQSP) in Assam and a parallel water quality initiative in Tripura, addressing arsenic, iron, fluoride and bacteriological contamination in groundwater. Under this programme, CML has installed Arsenic Removal Plants (ARPs), Iron Removal Plants (IRPs), Fluoride Removal Units and Bacterial Removal Units across 200 villages in Assam (90 villages in Kamrup and 50 villages in Nalbari, along with additional villages under source-based interventions) and 60 villages in Tripura.
CML now wishes to commission an independent Impact Assessment (IA) of this Water Quality Programme, to document and quantify the changes brought about through these interventions and generate evidence-based recommendations for scale-up, sustainability and convergence with government schemes.
Objectives of the Assessment
- Assess and quantify the changes observed among beneficiary households and communities as a result of the Arsenic, Iron, Fluoride and Bacterial removal units installed by CML;
- Assessment of usage of Point of Use filter for Arsenic Removal
- Assess the extent and drivers of adoption of purified water (JJM-supplied water treated through CML-installed units) among target households;
- Assess the overall impact of the programme on community behaviour change around safe drinking water practices;
- Assess how community ownership has been generated, including the functioning of Water User Committees/local caretakers and the collection of community water tariffs; and
- Develop actionable recommendations for strengthening adoption, behaviour change, ownership and sustainability of the installed units.
Key Thematic Areas for Assessment
- Adoption of JJM water through CML-installed purification units — extent of usage, reasons for adoption/non-adoption, and comparison with alternate water sources still in use;
- Behaviour change — shifts in household water collection, storage and consumption practices attributable to the programme; and
- Ownership & sustainability — functioning of community institutions (Water User Committees), regularity of community water tariff collection, and local arrangements for operation and maintenance of the units.
Scope of Work & Coverage
The assessment will cover a sample of 40 villages, constituting approximately 20% of the total 200 programme villages across Assam
and Tripura, as detailed below:
- State District(s) Villages Covered IA Sample (20%)
- Assam – Kamrup – Villages Covered: 90 – IA Sample (20%): 18
- Assam – Nalbari – Villages Covered: 50 – IA Sample (20%): 10
- Tripura – Dhalai / North Tripura – Villages Covered: 60 – IA Sample (20%): 12
- Total Villages Covered- 200 and IA Sample- 40
- The final list of sample villages will be shared by CML in consultation with the selected agency, ensuring representation across technology types
- (ARP/IRP/Fluoride/Bacterial units), districts, and years of installation.
Methodology
The assessment is expected to adopt a mixed -methods approach, drawing on both qualitative and quantitative tools, including at minimum:
- Group Discussions (GDs) with beneficiary communities/Water User Committees in each sample village;
- Interpersonal communication and informal interactions with community members, Jal Mitra (Pump operators) and frontline
- functionaries; and
- Individual household interviews/surveys to capture quantifiable indicators of adoption, usage, and behaviour change.
- Bidders are encouraged to propose an appropriate sampling framework, survey tools and analytical approach in their technical
- proposal, in line with the objectives and scope outlined above.
Deliverables
- Inception note, including finalised methodology, sampling plan and data collection tools;
- Cleaned primary data sets (quantitative and qualitative);
- A detailed Impact Assessment Report, covering findings against each objective and clear, actionable recommendations; and
- A summary PowerPoint presentation of key findings and recommendations, for presentation to CML and its partners.
