Two bored tunnels have carried the culverted Maldonado's overflow since 2012. The monitoring network funded by the same loan was never finished, and the World Bank's evaluators rated the outcome Moderately Unsatisfactory.

Two bored tunnels — 9.8 km and 4.6 km, both 6 m across — have carried the culverted Maldonado's overflow since mid-2012, financed by a World Bank loan and sized for a 1-in-10-year storm. Water enters them hydraulically; no source describes a sensor in that loop. The measuring layer is separate: rain, wind, flow and level sensors feed a control desk, and a Sistema de Alerta de Tormentas with automatic stations and a Doppler radar was begun in October 2016, its data to converge at the city's Centro Único de Coordinación y Control. Readings raise alerts and send crews — no source describes a pump or gate starting on a threshold. The Bank's own evaluation arm rated the loan Moderately Unsatisfactory: the tunnels got built, but only two of six secondary-network groups were under way at closing and funding fell short of a complete monitoring network under the loan.

Live 📅 since 2005

📊 Impact

World Bank ICR: the works were designed to prevent flooding in the city's Maldonado basin in a 10-year storm, with about 342,968 direct beneficiaries in the basin's critical zone. The Bank's Independent Evaluation Group nonetheless rated the project's outcome Moderately Unsatisfactory, with the secondary drainage network under way in only 2 of 6 planned areas at closing.

🎓 Lesson

Bundling concrete and instruments in one budget rewards the concrete. IEG's own lesson from this loan is that combining structural and non-structural components in one project needs specific implementation arrangements that give both weight — here the tunnels were finished and the monitoring network was not.

Sources

↗ World Bank — IEG ICR Review, Urban Flood Prevention and Drainage (P088220)Published 13 April 2015Independent review. Gives the Moderately Unsatisfactory outcome rating, appraisal cost US$189M against actual US$193.01M, an IBRD loan of US$134.01M (originally EUR 98M), board approval 5 April 2005 and closing 31 August 2012 after extension from 31 December 2010; states the secondary drainage works were 'underway in 2 of the 6 proposed areas, with the remainder expected to be completed with City funds', and draws the lesson that combining structural and non-structural components in one project is challenging. The PDF at the same document ID returned unparseable binary to our fetcher; this identical .txt rendition was read instead.
↗ World Bank — Implementation Completion and Results Report, ICR2686Published 28 November 2012Source for the tunnel dimensions (9.8 km and 4.6 km, 6 m inner diameter, both in operation from mid-2012), the design standard ('designed to avoid flooding in the area of the City within the Maldonado Basin during rain events of 10 year intervals'), the figure of roughly 342,968 direct beneficiaries, and the statement that 'shortage of funding meant that the Project could not achieve the development of a complete hydrological monitoring network for the City'. PDF unparseable; .txt rendition read.
↗ Gobierno de la Ciudad de Buenos Aires — Sistema de Alerta de TormentasOperator page. Dates the system to October 2016, describes a network of 34 automatic meteorological stations 'of which 10 are already transmitting data', a dual-polarisation Doppler radar then still being installed at Merlo, and data converging at the Centro Único de Coordinación y Control, 'currently operated by the Ministry of Justice and Security'. The page reads as an undated snapshot close to launch — we did not find a current count of stations actually transmitting, so the entry claims none. Nothing on the page describes automatic actuation of pumps or gates.
↗ Gobierno de la Ciudad de Buenos Aires — Red hidrométricaConfirms the sensing layer: 'Los sensores monitorean en forma constante la lluvia, la temperatura, el viento, el caudal y el nivel del agua', feeding 'un tablero de control donde se visualizan en mapas y gráficos con la finalidad de detectar variaciones en los caudales y anticipar posibles inconvenientes'. No sensor count, no public data feed and no automatic response described — the basis for this entry's placement as warning-only.
↗ Infobae — inside the Maldonado conduits, 2 July 2024Describes maintenance rather than control: constant inspection because 'en esos conductos pluviales una obstrucción puede generar un problema muy grande', robots in the smaller pipes, cleaning of some 900 km of conduits and 30,000 sumideros by Espacio Público e Higiene Urbana, and a 6 m conduit that routes inflow from the Province to the Riachuelo via the Cildañez. Also cites rainfall up about 11% over two decades. No sensor-driven control is mentioned anywhere in the piece.

What the mapping says
The ICR describes two 'drainage tunnels (of length 9.8km and 4.6 km respectively and 6m inner diameter)' and notes 'the tunnels only began to be operated in early to mid-2012'. Infobae (2024) reports the conduits still in service and under routine inspection.

What the mapping says
Neither the ICR's description of the tunnels nor Infobae's 2024 account of their operation mentions any sensor-controlled gate or pump on the tunnel inflow; Infobae describes inspection and cleaning, not control.
Caveat
This is a statement about what the sources describe, not a claim that no sensor exists.

What the mapping says
The city's pages describe data reaching a control board 'con la finalidad de detectar variaciones en los caudales y anticipar posibles inconvenientes' and an alert system improving emergency handling; neither describes automatic actuation of pumps or gates.
Caveat
The 'send crews' half is inferred from the stated purpose (emergency management), not from a described dispatch procedure.

  • Publisher names and source languages have not yet been classified; domains are recorded without guessing.
  • Existing source notes are descriptive locators, not page- or paragraph-exact citations.

🇺🇸 TARP: Chicago's Deep Tunnel & Reservoir System · Chicago Both tunnels fill hydraulically: Chicago's real-time control is still research, and Buenos Aires's monitoring network was never finished. 🇺🇸 DC Water's Clean Rivers Tunnels & the Consent Decree Behind Them · Washington D.C. Outside obligations built both: a federal consent decree in D.C., a World Bank loan in Buenos Aires — and neither tunnel is sensor-driven. 🇧🇷 Alerta Rio: rain gauges, thresholds & favela sirens · Rio de Janeiro Rio's gauges report every five minutes and a Civil Defence officer sounds the siren; Buenos Aires's readings raise alerts and send crews.
