TEDAGUA is to build the Taboada Waste Water Treatment Plant (Lima – Peru)
Through its parent company, ACS Servicios, Comunicaciones y Energía, S.A., the industrial branch of the ACS Group, TEDAGUA was awarded the contract for the construction and operation during 25 years of the Taboada wastewater treatment plant in Lima (Peru), which will be the largest water treatment plant built to date in South America. With an average flow rate of 14 cubic meters per second and a maximum flow rate of 20.3 cubic meters per second, it will serve a population of more than 4 million inhabitants, representing 56% of the population of Lima and Callao and 72% of the wastewater in both cities.
The direct beneficiaries are a current total population of 4,334,214 inhabitants (5,346,888 inhabitants in 2025), living in 27 districts (Miraflores, San Isidro, Lince, Santa Anita, Ate, El Agustino, San Luis, Cercado de Lima, La Victoria, San Juan de Lurigancho, Rímac, Breña, Jesús María, Pueblo Libre, Magdalena del Mar, San Miguel, La Perla, La Punta, Bellavista, Carmen de la Legua, Callao, Carabayllo, Comas, Independencia, San Martín de Porres and Los Olivos). The indirect beneficiaries will be the rest of the population of the Metropolitan District of Lima.
This is a concession contract (B.O.T.) awarded by the state agency Proinversión, which is controlled by the Peruvian Ministry of Finance. The total budget is 663 million euro, of which 120 million correspond to construction and the rest to operation for a term of 25 years.
The treatment plant will initially consist of pumping unprocessed water, grilles for solids, filtering with a mesh of 6 mm, degreasing - elimination of sand and final fine filtering of 1mm. It will be extended to include the tertiary treatment of effluent water. Originally, the pre-treated water will be piped through an underwater discharge pipe with a diameter of 3,000 mm almost 4 km from the coast, where, by means of a diffusers system, it will be diluted with sea water, without any effect whatsoever on the ecosystem in the area.
