Querétaro Aqueduct II
One of the largest hydraulic works in Mexico
FCC forms part of this project that is going to significantly increase the Mexican hydraulic infrastructure.
Over the last fifteen years, the capital and state of Querétaro have become one of the privileged living locations for thousands of people, having the highest annual growth rate in the country, increasing industrial and commercial activities, with extraordinary challenges regarding public services.
The Querétaro State Government commenced an iconic project, not only because of its magnitude, but also because it called for the joint participation of the Federal Government. the State Government and private initiative in order to tackle the root problems for future water requirements of the Querétaro Capital and. at the same time, release a significant volume of the aquifer operation by enabling the interruption of forty of the eighty-three existing wells for providing the city with potable water in order to allow their future recovery in benefit of future generations. This project was designated Acueducto II.
The contract was awarded to ICA, FCC Construcción, Aqualia and Mitsui de México for the construction, operation and maintenance of the system. The concession for the provision of water supply services to the City of Querétaro was established for eighteen years.
The project goal is to satisfy the Santiago de Querétaro water supply challenges in the short, medium and long terms and to eliminate the existing pressure on aquifer sustainability and guarantee the lowest production costs.
The aqueduct is 123 kilometres long and runs northeast to southeast through a large part of the State of Querétaro, crossing the continental watershed formed by the Río Pánuco and Lerma-Chapala basins. The production capacity is 1,500 litres per second and overcomes a total height of close to 1,200 metres from the diversion dam to the purification plant.
The water will come from the “El Infiernillo” springs, which are located on the River Moctezuma some four kilometres downstream from the rocky formation of the Moctezuma Canyon. This water is of high quality and its capture will not cause any negative environmental effects.
The spring water will be captured by means of a diversion dam located 800 metres downstream from the capture site. The capture site will include a first pumping station where the drive section is located that transports the water over 24 kilometres of abrupt terrain.
A second re-impulsion pumping station will be located 1,700 metres from the capture site and 585 metres high over the river course, from which the piping runs almost five kilometres through a tunnel.
The installations for the operations centre for the Acueducto II system will be constructed at the end of the drive section, together with the safety reserves of water and the system head purification plant.
It is proposed to capture and supply forty-seven million cubic metres of water annually to the cities of Querétaro, Bernal and Cadereyta in order take care of a population of one million inhabitants.
The full project is being carried out with complete respect for the environment, safeguarding society's wellbeing and incorporating cutting-edge technology into the system design.
