Infrastructure

Basic infrastructure in Brazilian favelas in the 2020s is mostly present, often irregular in quality, and uneven across regions. The remaining gaps — concentrated in sanitation — define much of what state programs claim to address.

Most favela housing in Brazil today has piped water and metered electricity. Sewerage, drainage, formal waste collection, and broadband internet are present at lower rates and with substantial variation across regions, cities, and within individual communities. The simple framing that favelas lack services has not been accurate at the macro level since at least the 2010 census; the more precise question is which services, at what quality, and how reliably.

Water

According to the IBGE Census 2022 release on aglomerados subnormais, a substantial majority of housing units in Brazilian informal settlements have access to piped water through a public network. In Rio de Janeiro, service is provided by the state utility CEDAE (and from 2021 by the concessionaire Águas do Rio) to most large favelas; in São Paulo, by Sabesp; in Minas Gerais, by Copasa; with similar patterns in other states. The remaining gaps are concentrated in newer occupations, in peripheral and rural-edge settlements, and in particular regions.

Water service quality, however, varies substantially within communities. Hillside favelas in Rio experience pressure drops at higher elevations; many residents rely on individual storage tanks (caixas d'água) to bridge intermittent supply. Billing and metering have been progressively regularized in larger Rio and São Paulo favelas, partly through agreements between residents' associations and the utilities.

Electricity

Electricity penetration is near-universal in identified aglomerados subnormais. The dominant pattern is metered service from the regional concessionaire — Light or Enel in Rio (depending on the area), Enel São Paulo (formerly Eletropaulo) in São Paulo's Sul and Capital areas, CEMIG in Minas Gerais, and so on. Informal connections (gatos) have historically been common and remain present in some communities, particularly in newer occupations and where regularized service has been delayed.

From the late 1990s onward, several utilities ran regularization programs in favelas, sometimes through partnerships with residents' associations, that converted informal connections into metered ones. The Light Comunidade Eficiente program in Rio and the Eletropaulo / Enel programs in São Paulo are recurring references in this literature.

Sanitation

Sanitation is the largest infrastructure gap. The IBGE 2022 release indicates that a substantial share of housing units in aglomerados subnormais lacks connection to a sewerage network — often by a large margin compared with non-favela urban housing in the same cities. Dominant alternatives are septic systems, irregular discharge into stormwater drains, and direct discharge into waterways. The consequences are environmental — water-body contamination, particularly in Rio's Guanabara Bay and the Capibaribe basin in Recife — and public-health (gastrointestinal illness, leptospirosis episodes after flooding, respiratory illness in vulnerable populations).

The 2020 Marco Legal do Saneamento (Law 14.026/2020) established new federal targets for universal sewerage coverage by 2033 and substantially restructured the sector toward private concessionaires. Implementation in favela areas has been uneven and is one of the most-watched policy debates in this period.

Solid waste

Waste collection in favelas is provided in larger communities by municipal services and by community-led collection in steeper or harder-to-access areas. Smaller streets and stairways are typically beyond the reach of standard collection vehicles; in Rio, the Comlurb operation has used backpack collection and community-paid sub-contractors. Where waste collection is insufficient, waste accumulates in informal disposal points or in storm drains, with downstream flooding and health consequences.

Internet and telecommunications

Mobile internet penetration is high, with most households using mobile data and many also using fixed broadband from formal providers (Vivo, Claro, Oi, TIM) or from community-based local internet providers. The IBGE 2022 data and the Cetic.br household survey on ICT use indicate that internet access in favelas, while lower than in adjacent formal neighborhoods, is now widespread and is one of the fastest-changing service indicators.

How service has been built

Infrastructure in favelas has not arrived through a single program. It has been built through three overlapping channels: large-scale federal and state programs (Favela-Bairro, PAC Favelas, São Paulo's Urbanização de Favelas, Belo Horizonte's Vila Viva); utility-led regularization programs through partnership with residents' associations; and self-organized community provision, particularly for last-mile water, electrical, and internet connections within streets the formal network does not reach.

What is contested

Two questions persist. The first is the appropriate division of labor between formal utility provision, community-managed provision, and hybrid arrangements; advocates of full formalization argue that residents have a right to standard services, while community-led provision has produced flexible and effective coverage in many cases. The second is the implementation of the 2020 sanitation framework, which has redrawn lines of responsibility and is being applied unevenly across favela areas.
