What does the Municipalidad de Concepción ask for to modify or extend a building already under construction?

Its published requirements are a request signed by the owner and the responsible professional, plans and schedules of the proposed changes covering both structure (if any) and architecture, and cost sheets. These are listed under the Catastro section of the municipal website, which also lists requirements for subdivisions (fraccionamiento) and location certificates. Confirm the current requirements for new construction directly with the municipality, since only the modification list is published online.

Which parts of Concepción flood?

Press reports from May 2025 describe flooding on Isla Bonita (Chaco'i), across the river from the old port, and on the north side of the city where the Arroyo Calaverita overflowed. That month the river reached 5.25 m at Concepción, compared with a normal level of 3 m. Lots near the riverfront or the Calaverita deserve a site-level flood check before you set foundations and floor levels.

Is city water reliable for a new home in Concepción?

ESSAP serves the city from a Paraguay River intake and reported 8,836 active users in October 2024. Service has been strained: very low river levels in 2024 forced work on the intake pumps, and in May 2026 residents of several barrios complained of lack of water while ESSAP promised distribution fixes and 1,200 m of new sewer collectors. Planning for on-site water storage is a sensible backup.

Concepción Today

Concepción, founded in 1773, is the departmental capital and a river port on the Paraguay River, with Route PY05 running east to Pedro Juan Caballero. In May 2026 the mayor said the city was gaining a place in the national economy, with Frigorífico Concepción and the Universidad Nacional de Concepción among its anchors. Paracel's pulp mill site at Paso Horqueta, about 20 km from the city, started infrastructure works in May 2026, and the president of the local merchants' and industries association estimated that about 10,000 people could need housing in the area at the construction peak.

Building in Concepción: What to Know

The Paraguay River and the Arroyo Calaverita set flood risk: in May 2025 the river reached 5.25 m at Concepción against a normal level of 3 m, displacing families from Isla Bonita (Chaco'i), across from the old port, while the Calaverita overflowed into homes on the north side of the city. Water and sewer service is provided by ESSAP, which draws raw water from the Paraguay River; in October 2024 the river stood at 0.38 m, close to its 1968 record low of 0.34 m, and crews had to work on the intake pumps to keep supply going. In May 2026 ESSAP announced replacement of 1,200 m of sewer collectors in critical spots after complaints about sewer collapses and water shortages in barrios such as Itacurubí, San José Olero, Inmaculada and Calaverita.

Why Investors Build in Concepción

Outside interest centers on the Paracel industrial hub, which employed more than 1,200 people directly as of May 2026, and on the Sudati plant announced for the same hub, worth more than US$200 million. Public works cited by the mayor in May 2026 include the Pozo Colorado to Concepción highway, to be the country's first concrete-paved route, the Gran Hospital del Norte and a future costanera (riverside avenue). Local business leaders expected growth in hotels, restaurants and real estate as the projects advance (InfoNegocios, May 2026).
