Lesson
Land acquisition in secondary towns can be a lengthy process and can cause significant delays in startup and implementation. Addressing the issue requires strong support from the relevant city corporations and district administrators, motivational campaigns, and adequate compensation packages. Advancing the preparation and approval of the Development Project Proforma to secure necessary funds for land acquisition early in project processing can reduce project startup delays.

The potential close-down and reconstruction of the Erlangmiao WWTP was totally unanticipated. ADB was not notified of this matter until the project completion review in December 2014. This indicates the lack of thorough and serious policy dialogue with the executing agency. If WMG notified ADB early of its urban plan updates related to the activities (e.g. Erlangmiao WWTP in this case) under the project, such low effective subproject could have been avoided through a scope change.

The project cost overrun is another major lesson learnt. Regardless of common factors, such as Chinese yuan appreciation and raise of labor and material prices, inadequate project preparation and insufficient engineering design contributed directly to the project cost increase because they resulted in costs underestimate at appraisal and frequent contract variations during implementation.

The lessons from delayed construction of the Huangpu Road WWTP showed necessity of securing domestic approval in advance, prior to the loan effectiveness. If flooding control permission had been approved earlier, construction of the plant could have been completed on schedule and thus the overall project output could have been delivered completely. The lessons learned from procuring the design, supply, and installation contract for the Huangpu Road WWTP were meaningful for improving procurement efficiency in similar projects and contracts.

The project experienced significant delay in implementation and in delivering the project outputs. This was mainly caused by the construction delay of the Huangpu Road WWTP, which was completed in August 2015, 1.5 years after the loan closing.

Wastewater Tariff Revision. NMG (Nanjing Municipal Government) should continue to regularly review the tariff level, monitor and ensure that the wastewater tariffs are capable of meeting full cost recovery, covering the O&M (operations and maintenance) costs, interest, depreciation, debt repayment, and a reasonable profit margin.

Flexibility in Project Design. Changes in the design of the project during implementation should be considered in order to achieve a better outcome. For instance, the cancellation of the Jiangxinzhou WWTP (wastewater treatment plant), because of the introduction of new technology to use the sludge to co-incinerate at a power plant, has provided a cleaner form of power generation and is good practice for recycling waste.

Loan Reallocation. To optimize the utilization of the loan, cost savings identified during implementation can be reallocated to other components during the midterm and final reviews. Under the project, NMG (Nanjing Municipal Government) was able to reallocate the proceeds from the cancellation of component E to the other components, resulting in optimum utilization of loan proceeds.

Implementation Arrangements. The project management office serves a critical coordinating function in executing projects that involve several implementing agencies. The NPMO's (Nanjing project management office's) strong leadership and good communication skills proved to be crucial for the efficient implementation of the project. In addition, the establishment of databases and monitoring mechanisms by each implementing agency during the early stages of the project was very useful. Assurance of a good partnership among implementing and oversight agencies is essential.

Land Acquisition and Sludge Disposal. Potential land for use by the project was secured and confirmed at appraisal and confirmed before loan effectiveness. However, land issues related to sludge disposal still arose during implementation, resulting in the cancellation of Component E. Sensitivity in site selection, careful assessment of land acquisition issues, and consultation with stakeholders during preparation are therefore essential..

Operation and Maintenance (O&M). In Nanjing, management responsibilities for O&M of river systems, drainage systems, WWTPs (wastewater treatment plants), and sewerage systems were fragmented between Nanjing Qinhuai River Construction Company and Nanjing Municipal Water Company (under NCIC or Nanjing Urban Construction Investment Holding [Group] Company Limited), NDMD or Nanjing Drainage Management Department (under NMUMB or Nanjing Municipal Urban Management Bureau), water resources bureaus, and the district governments. This resulted in considerable confusion and inefficiency.

The free connection policy has clearly shown its enormous impact on water supply coverage. A condition of connecting a premise to the water supply is that it must have a sanitation facility complying with local sanitation regulations. Residents are willing to install an approved sanitation facility so they can access the free connection to the piped system. Moreover, this policy has tremendously impacted sanitation coverage in the target communities.
