About 500km of pipes will be installed in the first phase to meet the needs of more than 200,000 people. The project involves the laying of approximately 500km of pipes and the design and construction of eight treatment plants with population equivalent capacities ranging from 4,000 to 60,000 as well as six lifting and pumping stations.
Vinci Construction Grands Projets has signed the design-build contract with Instituto Nacional de Aguas Potables y Alcantarillados (INAPA). It covers wastewater collection, transfer and treatment systems in the cities of Monte Cristi, Neiba, Azua, San Jose de Ocoa and San Cristobal. This project is part of the Dominican Republic’s government's cholera eradication programme.
In addition, an audit will be conducted with a view to improving the performance of the system and optimising the commercial service for the operator. Including six months of design studies, the works will take 42 months to complete.
The facilities are to comply with sustainable development criteria: simple operation, environmental protection and high-quality treatment. For example, final disinfection will take place in an ultraviolet radiation facility; its power will be supplied by photovoltaic panels, which cover 80% of overall energy requirements.
