The model will outline sustainable mechanisms for the operation and maintenance of small-scale piped water supply systems, enabling these communities to consistently access safe water for drinking purposes.LocationMujibnagar Union, Charfession Upazila, Bhola under DoE Small Island Project area (CR)- sustainable management of 16 mini piped water system serving 1,600 climate vulnerable Households in the project areasEstimated Duration8 months for community mobilization and developing a business model for sustainable operation and maintenance, starting after signing contractReporting to Technical Supervisor of this assignmentWASH Specialist, WASH Section, UNICEFBackgroundBangladesh has achieved substantial progress in expanding access to improved water infrastructure over the past four decades. This includes the development of urban piped water systems, their extension into small towns, and the installation of handpumps on shallow and deep groundwater aquifers, as well as technologies such as Pond Sand Filters (PSF), Iron Removal Plants (IRP), and Arsenic and Iron Removal Plants (AIRP). By the late 2000s, the country reached near-universal access (99%)[1]  to improved water sources. However, this aggregate figure masks persistent challenges in ensuring drinking water security, particularly for the poorest and most climate-vulnerable rural communities.Meeting the Sustainable Development Goals (SDGs) for safely managed drinking water in rural Bangladesh requires new approaches that address multiple, overlapping risks—water quality deterioration, pollution, climate vulnerability, declining groundwater levels, and frequent infrastructure malfunctions, especially in multi-user systems.Recent studies have quantified an exponential growth of private household electric pumps on shallow tube-wells, thereby more than doubling the number since the last estimates in 2006. This scale of infrastructure growth demonstrates the significant role of private capital, estimated to represent over one third of the total rural sector financial flows, as shown in forthcoming research by Fischer et al and in the national reporting of sector expenditure to the Global Analysis and Assessment of Sanitation and Drinking-water[2]. The significant expenditure by households continues to equalize access rates on and in premises across the country but is missing an opportunity to leverage those funding resources towards collective and multi-user systems where public oversight could improve safety, reliability and sustainability. This context presents an opportunity to attract non-traditional finance in new ways towards reliable and safe technologies managed under service models accountable to dynamic monitoring systems[3].Despite progress, several challenges remain:Complex social–ecological context:Bangladesh is one of the most challenging environments worldwide for delivering safe and reliable water services to a population of 170 million including approximately 116 million rural households (BBS Census report 2022). Although improved access appears high, national estimates ofsafely managedrural drinking water—considering functionality, proximity to the premises, and freedom from E. coli and arsenic—drop sharply from 99% to 39.3% (BBS–UNICEF, MICS Preliminary Report, 2025).Climate vulnerability in coastal regions:Approximately 20 million Bangladeshis live in the coastal belt, where climate-related hazards such as cyclones, floods, storm surges, and sea-level rise severely affect drinking water availability. Public WASH systems in these areas face high malfunction rates due to salinity intrusion and repeated storm damage. Salinity poses serious health risks, particularly for pregnant women, yet is not routinely monitored in national water quality assessments[4].Uncertain water quality:Water quality in both public and private systems remains inconsistent due to insufficient testing frequency and scale. A significant proportion of water points are contaminated with E. coli or arsenic (MICS 2025). Bangladesh continues to struggle with widespread natural arsenic contamination in shallow aquifers, and no comprehensive national testing of tubewells has been conducted since the early 2000s—despite a doubling in total installations.Infrastructure functionality gaps:Although the density of water points largely meets policy targets, operation and maintenance (O&M) challenges persist. On average, 13% of public water infrastructure is non-functional, with technology-specific non-functionality rates of 24% for rainwater harvesting systems, 47% for PSFs, 28% for ring wells, and 10% for handpumps[5].The transition from the Millennium Development Goals (MDGs) to the SDGs has shifted emphasis from simply providing infrastructure to ensuring risk-informed, safe, and reliable drinking water services. This shift calls for new service delivery models and governance approaches that strengthen risk management and water quality assurance.The momentum toward safely managed drinking water in rural Bangladesh presents an opportunity to design innovative enterprise models that blend public and private financing, enhance governance adaptability, and reduce risks to water quality and service reliability.Given the rapid expansion of private on-premises water demand—particularly small-scale piped systems—there is an increasing need to ensure sustainable, safe, and reliable service provision for drinking, hygiene, and domestic uses. However, most private-sector investments remain outside collective governance and regulatory oversight, challenging the long-term sustainability and equity of water services.In this context, UNICEF seeks to engage a consultancy agency/firm to develop a sustainable business model for climate-resilient mini-piped water systems inMujibnagar Union, Charfession Upazila, Bhola, under the Department of Environment (DoE)’s Small Island Project-climate resilient Project. The assignment focuses on the sustainable management of 16 mini piped water systems serving approximately 1,600 climate-vulnerable households. The business model will strengthen institutional coordination, improve information systems, and ensure financial sustainability through innovative, performance-based service delivery mechanisms—ensuring no one is left behind.Objectives, Purpose, and Expected ResultsThe purpose of this assignment is to engage a qualified consultancy agency/firm to develop a viable, climate-resilient, and financially sustainable business model for the safe, reliable, fully functional and equitable operation of 16 mini-piped water supply systems serving approximately 1,600 climate vulnerable households in Mujibnagar Union, Charfession Upazila, Bhola.The business model shall integrate public, private, and community roles to ensure year-round access to safely managed drinking water, strengthen institutional coordination, improve monitoring systems, and establish accountability mechanisms that protect the rights of underserved households living in highly climate-stressed small island environments.The overall objective of the assignment is to design asustainable, climate-resilient, and pro-poor water service delivery modelthat ensures reliable access to safe drinking water for climate-vulnerable communities through improved operation, maintenance, governance, and financial systems for small-scale piped water infrastructure.The consultancy is expected to achieve the following specific objectives:Develop a business modelfor the operation and maintenance of mini-piped water systems in for rural areas in Bangladesh.Design a pro-poor, cross-subsidy mechanismthat guarantees cross-subsidy mechanism for lifeline quantities (30 Liter per day per household Revenue Water + 10 Liter per day per household Non-Revenue Water) of safe water forextremely poor and vulnerable households, including women-headed families, persons with disabilities, and households with young children.Construction oversight: The agency will ensure technical supervision of construction works of 16 mini-piped water system constructed through DoE contractors.Establish a water quality assurance, Climate Resilient Water Safety Plan and monitoring frameworkthat ensures regular testing for key health-related parameters, including microbial and chemical contaminants, Water safety framework, aligned with national standards and/or WHO guidelines.Expansion of services for making viable business model,the DoE-UNICEF water supply project will only install basics infrastructure like installation deep tubewell and solar system with piped network to communal stand post for low income and hardcore poor at their courtyard. The agency will extend this pipe line to users’ premises (toilet, bathing place, kitchen areas etc.) with meter water supply facilities through user’s contribution as appropriate to expend this services.Develop a feasible, community-adapted O&M planthat enables long-term functionality of the systems through clear roles, capacity development, asset management, financial management procedures, and supply chain considerations.Strengthen community engagement and demand generation, including behavior change communication to promote the value of safe water, water safety plan, water management and good hygiene practices among climate-vulnerable populations to reduce secondary contamination.Develop scalable models for replication. The agency will prepare policy brief for development of sustainable business models for delegated management, performance-based contracting, or social enterprise operations that ensure efficiency, reliability, accountability, and sustainability.Expected ResultsThe consultancy will deliver a sustainable, pro-poor business model for the operation of 12 climate-resilient mini-piped water systems with possible increase to 20 systems in Mujibnagar Union, including a viable cross-subsidy mechanism for vulnerable households. Expected outputs include an O&M plan, an inclusive infrastructure design framework, and a water-quality monitoring protocol aligned with national standards. The assignment will strengthen private-sector engagement, community mobilization, and demand for safe water. By 2026, climate-vulnerable households—especially the poorest, women-headed families, and persons with disabilities—will have improved, reliable, and safely managed drinking water access through sustainable service delivery systems. of AssignmentThe consultancy agency/firm will be responsible for designing a comprehensive, climate-resilient, and pro-poor business model to support the sustainable operation of 16 mini-piped water systems in Mujibnagar Union.
