The Arjón Aqueduct system takes water from the Coronda River, which is part of the Paraná River alluvial valley. Untreated raw water is piped from the river to the treatment plant through a 1,200 mm diameter pipe, at a flow rate of 2.17 m³/s, according to the General Plan. Once treated, the liquid is then pumped through water mains and secondary feeders to each of the localities being supplied, where it will be stored in tanks.

The work will provide the populations in these areas with good quality drinking water, reducing public health risks from water-borne diseases, and allowing localities currently limited by water shortages to develop and flourish. Section 2 includes the execution of all the works involved for the stretch between Pumping Station No. 2, in Matilde, to the entrance chamber to the cistern at Pumping Station No. 3 in San Carlos Centro.

The course of the main water pipe, which is 19.5 km long, will lie parallel to local roads. The pipes used include HDPE DN 1000 mm K10, HDPE DN 1000 mm K08, HDPE DN 900 mm K08 and HDPE DN 900 mm K06, according to the section. The structure is expected to have the capacity to transport the flow envisaged with a 30 year horizon. A pumping station will be built on the trunk section in the town of Matilde, on the Provincial Road no. 36. The main feeder pipe will receive a flow of Q10 = 989 l/s with a delivery head of H10 = 82 mca. Likewise, in order to supply the town of Matilde, the idea is to aim for a design flow of Q10 = 3.3 l/s and H10 = 55 mca.
