This operational manual describes the process for planning and implementing performance-based contracts (PBCs) for nonrevenue water (NRW) reduction.
... Exibir mais + An NRW-PBC is a contract for outsourcing technical, commercial, and construction activities related to NRW reduction, while providing the contractor with incentives to achieve the desired results. Unlike conventional NRW reduction contracts in which contractors are paid based on inputs (for example, number of connections replaced), NRW-PBCs pay the contractor for outputs, such as amount of water saved, number of illegal connections detected, or number of customers receiving 24/7 service. NRW-PBCs differ from management contracts, concessions, leases, or other forms of private sector participation, in that the utility retains control of utility operations and assets. The PBC allows the utility to take advantage of the expertise and incentivized performance of specialized private sector firms to reduce NRW. NRW-PBCs do not entail privatization of management, operations, or assets. This manual can be read in its entirety for general knowledge of NRW-PBCs and the NRW-PBC preparation process. Practitioners can also reference individual sections of the guide during the NRW-PBC preparation process. The primary users of this manual are those involved in assessing, preparing, and implementing NRW-PBCs. This includes governments, water utilities, regulators, consultants, contractors, and international finance institutions.

Ratings for the Dakar Diamniadio Toll Highway Project for Senegal were as follows: outcome was moderately satisfactory, Bank performance was moderately satisfactory, and monitoring and evaluation quality was substantial.
... Exibir mais + Some lessons learned included: the intervention of the World Bank in this project, dedicated to the mitigation of the impacts of the major infrastructure on dwellers, combined with International Finance Corporation (IFC) support in the form of a loan to the private sector, was instrumental to enable the mobilization and coordination of both international funding institutions (African Development Bank (AfDB) and French Development Agency (AFD)) and the private sector in the financing and operation of the toll road. Clearly defining the boundaries of a project may sometimes be a delicate task, and teams should always keep a clear view of the project’s objectives at preparation. A set of actions to handle the resettlement processes were piloted during the project that appeared very relevant and should be considered best practices, including the opening of a local office in the affected areas serving as a one-stop shop near the affected people in Pikine for the processing of compensations and collection of complaints; the hiring of nongovernmental organizations (NGOs) and independent safeguards specialists to help dialogue with the people, mitigating the risks of misunderstanding and speeding-up the processes; and the design and implementation of an extensive communication strategy. Upon conclusion of the infrastructure, the pace of implementation of the resettlement processes slowed down substantially, affecting the overall project implementation.

The development objective of the Gansu Rural-Urban Integration Infrastructure Project for China is to provide residents in select areas of Wuwei municipality and Linxia County with expanded all-weather access to rural and urban areas.
... Exibir mais + Some of the negative impacts and mitigation measures include: (i) traffic noise prediction of the road is based on the noise model and algorithm; (ii) the traffic noise prediction values for the typical characteristics of the section along the road are calculated; (iii) road traffic noise has caused a certain degree of impact on the acoustic environment along the line; (iv) Do not build sensitive areas that require special protection such as schools, hospitals, and residential buildings within the range of the distances on each side of the road. If new construction is required; (v) when correcting the traffic noise value, comprehensive consideration shall be given to the factors such as topography at the sensitive point and the height difference between the road surface and the road surface.

Like in many large cities in developing countries, traffic in Grand Casablanca, Morocco, is congested and public buses are crowded. These conditions are alleviated by a combination of supply-side infrastructure expansions, such as more buses and new road capacity, and demand-side pricing instruments, such as parking and fuel taxes.
... Exibir mais + Using an empirical urban transportation mode choice model for Casablanca, this study finds a mix of these expansion policies and pricing instruments to alleviate congestion and maximize aggregate social welfare. The optimal mix is sensitive to the marginal costs of the infrastructure expansions. If the city were to spread out in its periphery where land constraints do not exist and land is available at lower prices, a supply-side instrument, particularly the optimal expansion of roads, would be far more effective in achieving welfare gains than the use of optimal pricing instruments without new roads. By contrast, if the city were to densify in already built-up areas, land and other physical constraints and the high price of land may leave expensive “elevated roads” as the only option. In this case, demand-side instruments together with the elevated roads would equally contribute to reduce traffic congestion and in-bus crowding.

The development objective of Corridor X Highway Project is to increase transport efficiency and improve traffic safety on the three project sections of Corridor X, between Nis and Dimitrovgrad and Grabovnica and Donji Neradovac respectively, and to improve road management and road safety in Serbia.
... Exibir mais + This restructuring requires the following changes : (i) ensure Bank involvement in the remedial measures for a landslide located in Gradinje along the E80 road section constructed in the project, which would involve design, construction, and supervision of the remedial measures; and (ii) continue the financing of technical assistance including engineering supervision consultant contracts that are in place for works financed by other International Financial Institutions (IFIs).
