Lesson
Continued timely adjustments in tariffs could make projects financially viable. The project financial reevaluation at completion concluded that the project was financially viable subject to continued timely adjustments in tariff. This has legal basis as Decree 124/2011/ND-CP allows WSCs to propose water tariffs in a tariff roadmap, which provincial governments approve. The tariff roadmaps of the participating WSCs included adjustments every two years. However, only one adjustment was made in 2019–2022 due to the impacts of COVID-19.

Strong project design, including carefully thought-out subproject selection criteria and adequate financial assessments can help reduce the need for scope changes and mitigate the risk of implementation delays. At approval, this project included seven subprojects in five provinces. Four of the seven subprojects were dropped in 2016 and 2017 because of changes in the companies’ investment priorities, changes in management due to the equitization process, and/or insufficient financial capacity.

Urban land acquisition in densely populated areas poses significant challenges. Compensation rates may rise during implementation, driven by urbanization rather than project schedules, potentially causing delays beyond the control of the project. Aligning civil engineering procurement with land acquisition progress is essential to prevent contractual disputes. Close collaboration, clear milestones, and effective communication mitigate risks. Establishing a resettlement information system aids in early issue identification, maintaining transparency.

Effective institutional arrangements and adequate project management capacity are crucial to project success. At the onset, effective institutional mechanisms and linkages were established to ensure efficient project management andimplementation. Extensive, expanded, and continuingCapacity development through hands-on training, advocacy, and dissemination of knowledge products provided a cohesive approach to ensure that innovative technological solutions to groundwater degradation were effectively addressed and absorbed by stakeholders.

Effective knowledge transfer requires adaptation to local context and the participation of stakeholders in the design and preparation of the necessary materials and documents.The project supported the development of manuals and guidelines (e.g., corporate plans, landfill operation guidelines, public–private partnership guidelines). However, preparation of the documents had minimal participation from key stakeholders and there was limited communication to explain the documents to intended users.

Border crossing points (BCPs) will risk becoming stranded assets in the face of border disputes and other related issues. BCPs completed under the project have remained closed for traffic since April 2021 following a border dispute between the Kyrgyz Republic and Tajikistan. By May 2024, around 10% of the border line with total estimated length of 970 kilometers remained to be delimitated. The countries are determined to complete the process and sign a border agreement within 2024. Until the delimitation is completed, the potential traffic volumes across the borders will remain unknown.

Knowledge gained from projects needs to be shared to optimize benefits. The knowledge developed through the project—the groundwater protection engineering and non engineering measures—would be beneficial if made accessible and promoted to key stakeholders. The recording of data on groundwater mitigation, water reservoirs, river and embankment protection, and wetland benefits should be maintained.

A centralized and unified real-time web portal expedites the execution of all project processing and decision-making pocedures, and is an invaluable asset to the successful implementation in this day and age. The lack of coordination among various branches across the different zones of India hampered the operations of the tranche 1 project. A beta version of a unified central web portal for the entire investment program that was put in place was not able to minimize the operational hurdles faced by PNB, due to the lack of institutionalization across all branches.

Lesson
Flexibility in project design is required to respond to changes in subproject scale and adapt capacity support to the changing needs. This project was implemented across eight provinces, with significant differences in the size and scope of provincial waterworks (PWW) subprojects and local capacities. A flexible design was crucial to its successful implementation.

Extensive upstreamCapacity development is required to address municipalities and contractors’ limited capacities and understanding of complex design, build, and operate (DBO) contracts. Those limitations delayed the procurement and implementation of the wastewater treatment plant (WWTP) contract under this project.

Organizational interventions support and reinforce capacity building for institutional knowledge retention. For instance, organizational intervention, such as handover procedures and an operations manual developed as part of the DBO contract, combined with operation and maintenance staff training to ensure knowledge retention and sustained institutional strengthening in maintaining the operational standards for potable water supply prescribed by the Bhutan Drinking Water Quality Standard, 2016.

Inadequate staffing levels and frequent staff turnovers make training efforts less effective and sustainable. Under their existing structures, all the key project agencies faced challenges due to the perennial shortage of key personnel, made worse by high staff turnover. Therefore, it has been essential for ADB to continually review staff skills and capabilities and corporate structures, and implement measures to fill capacity gaps.

Resource constraints can impede the participation of smaller firms in ADB procurement as well as hinderCapacity development of counterpart agencies. Smaller firms struggled to respond appropriately in some bidding processes, which resulted in their being considered ineligible to participate. The project implementation unit experienced resource constraints, which hindered sustainedCapacity development throughout the project and the participation of outer islands officials in the training activities.

Lesson
Wide time gaps between the finalization of construction cost estimate, initiation of the bidding process, and awarding of contracts should be avoided as these could lead to time and cost overruns. There were significant time gaps of 4–5 years between the finalization of the DPRs, including cost estimates and the completion of the bidding process. Besides causing startup delays, this also led to higher contract costs in comparison to the engineering estimates.
