Overview A major challenge of urbanization in South Asia is the provision of continuous water supply with 100% coverage of households, and ensuring sustainable water service delivery. In most of the cities in the region, the urban population suffers from intermittent water supply services with partial coverage, limited connection to households, and water quality issues. Poor water supply services create a downward spiral, leaving customers unwilling to pay water tariffs, insufficient revenue for scientific system maintenance and improvement, and further service deterioration. Even new infrastructures often fail to sustain quality water services because of the service provider’s lack of technical, institutional, and financial capacity, and limited social support. To address these challenges, the State Government of Karnataka and the Asian Development Bank (ADB) have been working on urban water infrastructure development projects. This article is adapted from 25 Years of Partnership with Karnataka: Evolving Model for Sustainable Urban Water Service Delivery, an ADB report that looks at pioneering projects and lessons learned that can be replicated in urban sector interventions in South Asia. Interactive Partnership for Improved Interventions Project interventions in urban Karnataka have evolved in the last 25 years, reflecting lessons from previous projects and innovations in new project design and scope to improve urban water services, and operation and maintenance arrangements. The partnership started with sector analysis and capacity building through technical assistance, followed by policy dialogues that identified required investment interventions and policy actions. Procedural, technical, and institutional challenges in implementation and operation and maintenance were jointly reviewed and corrective actions were taken. Lessons learned from past programs were shared during consultations held for designing the ensuing interventions. The success of project-specific interventions have been scaled up and institutionalized to bring broader changes in subsequent phases. The interactive partnership has promoted institutional transformation, adopting a phase-wise programmatic and inclusive approach to ensure sustainable service delivery in urban Karnataka. Ilkal Model: Achieving 24/7 Water Supply Ilkal, a small town in North Karnataka known for its silk sarees and red granite, suffered from intermittent water supply services. Public water supply coverage reached only 57% of residences with intermittent water service. Karnataka Urban Infrastructure Development Finance Corporation, under an ADB-supported project, introduced good water supply practices to the local municipality and Ilkal became the first municipality in India to achieve 100% water supply coverage all day, every day in every household. The Ilkal model provided service connections to individual houses, imposed district-metered areas to reduce water losses, introduced an innovative contract modality (performance-based construct and operate contract), used participatory planning, and conducted rigorous community development through sensitization and behavioral change campaigns. The performance-based construct and operate contract was designed to ensure optimal risk allocation between the public sector for project design and a private operator for project construction and operation, and a performance-based payment to encourage the private operator to complete construction in a timely manner and deliver a better quality of service to the customers. The private operator carries out construction after validation of the detailed designs provided by the public sector and operates the system for 4 years before transferring operations and maintenance back to the public authority. This model works well for water supply improvement because it holds a single contractor responsible for both construction and operations and maintenance. The arrangement ensures that contractors deliver high-quality infrastructure because their future remuneration depends on their performance during the operations and maintenance phase. Modality of a Performance-Based Construct and Operate Contract PBCOC = performance-based construct and operate contract.

This arrangement succeeded in providing Ilkal continuous water supply, reducing nonrevenue water, encouraging water conservation, and recovering costs for operations and maintenance. Through district-metered areas, physical losses fell to less than 8% from 50%. Also, water consumption was significantly reduced to below 100 liters per capita per day, against the average India standard of 135 liters. While ADB initially provided operation and maintenance cost support, this expenditure was fully covered by user charges by 2019, and the contract has been extended between the municipality and the contractor. High tariff collection efficiency ensured full recovery of the operation and maintenance expenditures. Other key features of the Ilkal model are extensive participatory planning and enhanced community awareness programs to facilitate inclusion and behavioral change of customers, sensitizing communities on hygiene, water supply, and waste management aspects, and encourage a willingness to pay and the adoption of volumetric tariffs. Community involvement in the program from its inception made planning process grounded, established local ownership, generated an enabling environment that addressed stakeholders' concerns about metering and volumetric tariffs, and clarified the role of the private operator. KIUWMIP Model: Building a Robust Virtuous Cycle in Water Services The Karnataka Integrated Urban Water Management Investment Program (KIUWMIP) was designed to enhance sustainable water security and coordinate the planning, development, and management of urban water resources. The program incorporates several key designs that include 24/7 water supply, 100% coverage, house service connections, and nonrevenue water reduction through district-metered areas in all project towns. The performance-based construct and operate contract modality piloted in Ilkal is applied to all water supply contracts under the KIUWMIP. The program avoids complex project scope, limiting interventions to only 7 towns in 2 tranches. This model also includes transformative policy and institutional reforms at the state level to ensure sustainable water service delivery. In addition to state-level policy reform, the initiative introduced innovative implementation mechanisms in project towns, such as dedicated funds to incentivize reform implementation, and the introduction of newly developed information technology modules for service delivery and dynamic asset management. An incentive fund was set up to motivate urban local bodies to implement reforms and become efficient and responsive municipal service providers. The incentive fund is implemented in 3 stages: financial and commercial capacity enhancement; technical capacity enhancement; and sustainable management capacity enhancement. Eligible expenditure under these activities and incentives allocated are given upon successful accomplishment of the reform actions. Enhanced information technology modules were also developed to help the urban local bodies operate their water services sustainably. The modules are designed to improve information management—with enhanced data capture, including establishment of comprehensive customer database, analysis, benchmarking, dissemination, and monitoring—and management decisions on water services. The integrated modules enable the urban local bodies to make timely management and planning decisions in asset management through the digitalization of property-linked customer databases, GIS mapping, and supervisory control and data acquisition. Building on the Ilkal model, the KIUWMIP model established a robust virtuous cycle for sustainable water service delivery.

Lessons Learned Evidence-based project design, participatory planning, support from local beneficiaries, and institutional arrangements are key to create a virtuous cycle for sustainable water services. The experiences in Karnataka provide lessons for urban development in other Indian states, South Asian countries, and beyond. Access to high-quality services must be an explicit target of water projects. Maximizing project impact to beneficiaries and providing a complete solution should be the top priority and the first round of a virtuous cycle for water services. Well-defined project design and scope minimize implementation problems. During project preparation, capacity should be assessed to find the right balance between project complexity and implementation capacity. Extensive community awareness programs are essential for making the planning process grounded and inclusive. Technical interventions aided with community engagement are key factors for bringing success and inclusivity in water projects. Institutions matter. Continuous institutional transformation and business process reengineering of project interventions help ensure sustainable water service delivery at a larger scale. A virtuous cycle cannot be built in a day. Interventions have evolved over decades through constant interactions among stakeholders and establishment of trust-based development partnerships. Development partners should learn from past experiences, adopt a programmatic approach, and continue to reach out to beneficiary communities to ensure sustainable service delivery. Resources A.
