Water and sanitation master plan for the metropolitan area of Puerto Iguazú

Consultation with the Aboriginal Communities Mbya Guaraní

We are designing the new works to be built to provide drinking water to the City of Puerto Iguazú and the 600 hectares where the aboriginal communities Yryapu, Ita Poty Mirï, Jasy Porá and Tupamba’e reside. The works will include:

  • A new water intake and treatment work of better quality, which will be supplied from the Paraná River.
  • Give water to all existing networks.
  • New networks for the entire city.
  • Install pipes and tanks to give water to the indigenous communities of the 600 ha.

As it is the best option from a technical and environmental point of view, it has been planned that the tanks are placed so that they are not more than 200 meters from all the houses in the nearby area.

Community centers (schools, health centers, etc.) can be connected, where possible, directly to the water network.

It is proposed to install pipes in the internal streets and tanks with 4 taps in all the communities of the 600-hectare area.

In a meeting that took place in mid-September, the four Mbya Guaraní indigenous communities, settled in the 600-hectare area in the city of Puerto Iguazú, were informed about the best possibilities of having potable water, as well as to consult their opinions on the works and possible actions in order to strengthen the communities in relation to drinking water works through an Indigenous Peoples Plan (PPI) to be executed jointly with the works by the construction company.

The meeting concluded with the signing of a Minute indicating the suggestions received from the communities.

Derivation weir on the Salado River, collection work, link channel, link to the De Dios stream and complementary works

Latinoconsult carries out the project review and supervision of the works of the diversion dam over the Salado river, the intake work, the link channel, the connection to the Canal de Dios and the complementary works, in various locations, Copo department, province of Santiago del Estero.

The main characteristics of the works are described below.

DERIVATIVE AZUD

The leveler weir work (located in the territory of the province of Santiago del Estero, about 3 km south of the border with the Province of Salta; near the town of Cruz Bajada), is developed across the river Salado , and will constitute a hydraulic structure in charge of raising the water level to generate a sufficient difference in level to guarantee its entry into the intake work of the Link Canal, which has been established at 18 m3 / s. It has a total length of 192 m made up of a spillway with thirteen spans of 12.3 m and nine flat gates of 2.7 m each with electromechanical drive.

The volume of reinforced concrete that this work will require is in the order of 2,047 m3. The work has a fish transfer structure, designed to ensure the migration of these vertebrates during spawning periods. It has been planned that a bridge of type A-30 of the D.N.V. to access the right bank of the Salado river and its approach embankments.

The weir is complemented by the lateral closures, on both banks of the river, made up of embankments of compacted cement soil, which aim to prevent overflows, reducing the flood spot to a minimum and protecting the surrounding properties. to the closing zone.

COLLECTION WORK

It has been proposed, for the capture of the flows to be derived, a desander area as a pre-intake and within the riverbed. It is rectangular in shape and its sides perpendicular to the flow are defined by gates through which the cleaning operations will be carried out. Its dimensions are 71 m long by 33.6 m wide.

LINK CHANNEL

Following the intake work and the transition zone in between, a link channel will be built between the intake and the distribution work (node) located 500 m downstream and from which the necessary flows will be derived to the Canal de Dios and also the future canal to Figueroa.

FLOW DISTRIBUTION NODE

At the end of the link channel, progressive 500 m, the work is located that will allow the diversion or distribution of flows both towards the Canal de Dios and towards the future canal to Figueroa.
The regulation of the derived flows is executed by two sets of flat gates, manually operated, of two and four units, respectively.

NEW CHANNEL OF GOD

It is a pipeline that links the flow distribution node, already described, with the current Canal de Dios. This linking channel will ensure the permanent service of the Canal de Dios with a conduction capacity of 3 m3 / s. The length of this pipeline is 21,865 m intercepting the current Canal de Dios coinciding with the foot of the existing waterfall upstream of the derivation to the Virgen de Huachana canal, from where the Canal de Dios continues with its current scheme.

MAINTENANCE AND IMPROVEMENT OF PROVINCIAL ROUTE No. 2

In view of the enormous importance of this work and the importance of it in the northern province, it is essential to maintain and improve Provincial Route No. 2, a road structure that will allow safe access to the entire work, weir and canals, regardless of weather conditions or other circumstances.

MEDIUM VOLTAGE ELECTRIC LINE

A medium voltage power line was built through which energy will be supplied to all the Azud facilities, intake work and accessory structures, at 13.2 KV three-phase. Length of 30 km from SETaN 33 / 13.2 located in the town of Ahí Veremos to the site of the Azud site.

Currently, work is being done on the concreting of the intake and intake work to the connecting canal and the new Canal de Dios, which is excavated up to the progressive 10,000 m with 30% of it already lined. The improvement works of Provincial Route N ° 2 and the embankments of lateral closures on both banks of the Salado River are being completed.
