In its 17-year partnership with the National Water Commission, VINCI Construction Grands Projets has been active on projects designed to provide people in Jamaica with improved access to water resources over much of the island, including the northwest parishes, in Negril, Lucea, and Montego Bay for drinking-water production and distribution systems, in Kingston for Constant Spring, Seaview Mona & Hope and in Falmouth and Ocho Rios for treatment-plant upgrades, at Port Antonio for a multi-use urban network (drinking water, wastewater, and drainage), and for wastewater treatment plants at Boscobel and Elletson Flats. We provide services at all stages of the water-management cycle, including modular solutions that meet specific client and local needs. VINCI Construction Grands Projets has had a hand in no less than 80% of Jamaica’s water production, including raw river water and groundwater table intake, various treatment processes, storage, supply, and distribution to consumers, along with water-network management, invoicing systems for consumer use, and water purification prior to its return to the environment.
The Cork wastewater treatment and mud-recycling plant, located at Carrigrenan at the very tip of the verdant Little Island peninsula at the mouth of the Lee River and 15 kilometres east of Cork, was upgraded to serve a population of 250,000. The plant is the final component in the city’s water-sanitation network. VINCI Construction Grands Projets led the civil-engineering mandate that includes 16 hydraulic storage tanks, 10 reinforced-concrete transfer chambers, 7 buildings, 23,000 m3 of concrete, and 3,800 tonnes of steel. The plant was opened in January 2004.
In 2014, VINCI Construction Grands Projets signed its first contract in the Dominican Republic with the Instituto Nacional de Aguas Potables y Alcantarillados (INAPA).
The goal was to design and build a wastewater treatment system in the cities of Monte Cristi, Neiba, Azua, San Jose de Ocoa, San Cristóbal, and Villa Vasquez.
This design-construction project, covering 6 cities, consists of the design of 400 km of sewerage systems, 10 pumping stations, 5 lagoon water treatment systems and 1 activated sludge water treatment system.
The project also includes the installation of a 54-km sewerage system, the construction of three pumping stations (270, 170 and 11 m3/hour) and a lagoon water treatment system. In Villa Vasquez, it involves constructing a 36-km sewerage system, one pumping station (270 m3/hour) and a lagoon water treatment system. In San Cristóbal, the project consists of the construction of an activated sludge water treatment system. Finally, with the assistance of WMI (VINCI Construction Grands Projets subsidiary), we have the task of establishing a technical diagnosis for drinking water supply.
In operation since 1976, the Marne Aval (downstream) SIAAP water treatment plant in Noisy-le-Grand was entirely modernised in 2009. This wastewater treatment plant is compact, modern and highly advanced technologically. It features the most stringent techniques for high environmental quality in the construction sector. So, this modernisation doubles the wastewater treatment capacity of the Marne Aval plant and reduces the space required.
VINCI Construction Grands Projets has participated in the modernisation of the Brussels South filtration plant, which was opened in 2000. The project, including the implementation of an entirely new water, sludge, and odour treatment equipment, is now able to significantly improve the quality of the water treated, especially on nitrogen and phosphorus, for 25% of the wastewater in the Brussels region.
The Communauté d’Agglomération du Pays Ajaccien (CAPA Ajaccio urban district council) has been engaged in a voluntary effort to restore the quality of water. To sustain this initiative and create the required conditions for a regional development project, the state and the CAPA have signed the “Horizon 2013 – Contribution of Ajaccio to cleaning up the Mediterranean” agreement to upgrade the agglomeration’s sanitation system so that it meets the standards of the European Union’s urban wastewater treatment directive.
VINCI Construction Grands Projets was mandated by Sri Lanka’s national agency for drinking water and sanitation to rehabilitate and expand the drinking-water treatment plant in Kantale. The project calls for the construction of a new 1,500-cubic-metre raw water storage tank, new water-treatment capacity equal to 18,000 cubic metres a day, and a new 1,500-cubic-metre tank to store treated water. The project also covers the rehabilitation of all structures and buildings in the existing plant, including replacing process, electromagnetic, and electrical equipment. Also included in this project are the development of two water intakes and raw-water pumping stations and supply and installation of the equipment for the treated-water pumping station. Finally, the project also covers automation of the treatment plant and pumping stations and supervision of the drinking-water distribution system as a whole for the region of Trincomalee.
As compared with the rest of Cambodia, Phnom Penh, the capital, is well-supplied in drinking water. However, this city with a population of 1.6 million is adversely impacted by uneven access to drinking water from one community to the next – a problem aggravated by its fast-paced population growth and industrial development. In response to this situation, the Phnom Penh Water Supply Authority (PPWSA) decided, as part of its 2005-2020 Master Plan, to build a new treatment plant in Niroth to produce drinking water. The project includes a water-intake system in the Mekong River, a raw-water pumping station, a filtration facility, and a treatment plant that feeds potable water into the city’s distribution system. Given the project’s considerable scope, a decision was made to divide it into two phases, with each phase encompassing a capacity of 130,000 cubic metres a day. A call for tenders was issued for each phase, and VINCI Construction Grands Projets won the call for tenders for the second phase in 2014, one year after the entry into service of the initial phase.
As part of developments north of the city of Doha, the capital of Qatar, a consortium consisting of VINCI Construction Grands Projets, QDVC, and Entrepose Contracting was entrusted with the task of building the largest wastewater-pumping station in the Gulf States. The structure was designed to collect, raise, and convey wastewater from North Doha to a plant located some 20 kilometres to the north in the desert. The project included construction of a wastewater-pumping station with a capacity of 900,000 cubic metres a day as well as the supply and installation of pipes.
We built a wastewater treatment plant in the commune of Saint Joseph on Reunion Island for Communauté d’Agglomération du Sud (CASUD).
