The Project consists of the following:

• Component I: Sanitation Infrastructure. This comprises construction of sewage collection network, trunk collector, pumping stations, pressure lines, sewage treatment modules and household sewage connections.
• Component II: Environmental Rehabilitation. This comprises removal of sediments and surface vegetation from the two lakes, preparation of environmental studies and plans, monitoring of raw water and treated water and conducting environmental education workshops.
• Component III: Institutional Strengthening and Innovation. This comprises upgrade of water analysis laboratory, preparation of design and modelling studies for biogas plant for sludge reuse and water loss control program in central Belém and conducting community workshops on gender and diversity.
• Component IV: Project Administration, Audit and Evaluation. This comprises consultancy services for project management, construction supervision, external audit and evaluation for the Project.

The Project’s outputs to be achieved by year 5 from loan signing date are:

• Construction of 120 km sewage collection network, 4.5 km trunk collector, 14 pumping stations, 2.5 km pressure lines, 2 sewage treatment modules and 31,500 household sewage connections.
• Removal of about 0.35 million cubic meters of sediments from Água Preta Lake, removal of surface vegetation across about 0.58 million square meters from Bolonha Lake, preparation of environmental studies and plans for the Project, define 29 raw water monitoring points at the two lakes and 50 supplied water monitoring points in the Central Zone distribution network of Belém and conducting workshops under the environmental education program.
• Upgrade of the water analysis laboratory, preparation of design and modelling studies for implementing a biogas plant and a water loss control program in central Belém and conducting community workshops on gender and diversity.

These outputs are expected to translate into the following Project outcomes that are to be realized starting from year 6 from loan signing:

• Improvement in water quality index of Água Preta and Bolonha lakes.
• Increase in percentage of population connected to the sewage network of Belém and Ananindeua.
• Reduction in monthly lake cleaning operating cost.

The Project will contribute towards achieving universalization of sanitation services and revitalizing water bodies serving as the main water source in BMR as envisaged in the Basic Sanitation Policy and Multi-Year Plan 2024-2027 of Pará.

The Government of the State of Pará will execute the Project through the Sanitation Company of Pará (Companhia de Saneamento do Pará or COSANPA) which will oversee day-to-day implementation of the Project. A project management unit within COSANPA will be responsible for carrying out bidding, contract management and supervision of works and services.

The implementation period for the Project is five years from 2025 to 2029.

The Project has been categorized as Category B in accordance with NDB Environment and Social Framework. The main Project-related environmental and social impacts include impacts on permanent protected areas, disturbance of aquatic habitats, contamination from sewage handling and disposal, gender-related issues from presence of external labour in the vicinity of local communities, potential impacts on cultural heritage sites, construction-induced environmental impacts, community nuisances including utility service interruptions and traffic disturbances, and occupational health and safety issues.

The Project’s environmental and social impacts and risks will be further identified, assessed, and mitigated through conducting simplified environmental impact assessments, development of environmental and social management plan and stakeholder engagement plan, and adherence to country system requirements. These provisions have been included in an Environmental and Social Impacts Management Plan devised by NDB for the Project.

The Project will be financed through loans from NDB and FONPLATA and funding from the state’s budget.
