Visiting Reservatório De Rio D’Ouro in Nova Iguaçu, Brazil: Tickets, Hours, and Essential Tips

Date: 14/06/2025

Introduction

The Reservatório De Rio D’Ouro, nestled in the Serra do Mar mountain range within Nova Iguaçu, stands as one of Brazil’s most significant feats of early engineering and environmental stewardship. Since the early 20th century, it has played a crucial role in supplying potable water to the ever-growing population of Rio de Janeiro, while its integration into the lush Atlantic Forest ecosystem has made it a beacon of both cultural heritage and biodiversity conservation (Cedae; Nova Iguaçu City Hall; INEPAC, 2020).

This comprehensive visitor guide provides detailed insights into the reservoir’s history, engineering, architecture, environmental context, visitor logistics, and conservation efforts—equipping travelers, students, and heritage enthusiasts with everything needed for a rewarding experience at one of Nova Iguaçu’s most treasured landmarks.

Historical Overview

Origins and Early Construction

Conceived as a solution to Rio de Janeiro’s chronic water shortages, the Reservatório De Rio D’Ouro was constructed between 1908 and 1913 by the Companhia de Águas do Rio de Janeiro. Its site was selected for the perennial Rio D’Ouro river, ensuring a stable water source for both urban and rural communities (Cedae). The reservoir’s completion marked a milestone in Brazilian civil engineering and laid the groundwork for modern water management systems in the region (Nova Iguaçu City Hall).

Integration into the Guandu System

As Rio de Janeiro’s population expanded, the reservoir became a key component of the Guandu System, connecting to one of the world’s largest water treatment plants and ensuring a reliable supply for millions (Guandu System Overview). Ongoing upgrades have reinforced its infrastructure and integrated advanced monitoring technologies, keeping the reservoir at the forefront of operational safety and efficiency (Cedae Modernization).

Engineering and Architectural Highlights

Dam Structure and Hydrological Management

The earthfill dam, standing about 30 meters high and stretching over 400 meters, was innovative for its time, utilizing local clay and rock to achieve structural stability. Its spillway system and impermeable core ensure resilience against tropical storms and prevent seepage, while modern telemetry enables real-time monitoring (ANA - Agência Nacional de Águas).

Architectural Features

The reservoir’s neoclassical design, robust masonry walls, arched spillways, and stone-and-iron sluice gates exemplify harmonious integration with the Atlantic Forest. Ancillary service buildings, with traditional tiled roofs, blend seamlessly with the landscape (INEPAC, 2020). Notable artistic elements include bronze sculptures by Carrier-Belleuse and a monumental fountain (O Globo).

Environmental and Cultural Significance

Conservation and Biodiversity

Situated within the Tinguá Biological Reserve, a UNESCO-recognized protected area, the reservoir contributes to safeguarding endangered species, such as the golden lion tamarin, and preserves watershed functions critical for Greater Rio de Janeiro (ICMBio - Tinguá Biological Reserve; BBMag). The surrounding Atlantic Forest acts as a natural water filter and climate regulator.

Heritage Value and Education

Designated as a state heritage asset by INEPAC in 1989, the reservoir is a symbol of local identity and engineering achievement (INEPAC, 2020). It is a hub for educational programs, community art, and environmental awareness, fostering stewardship among residents and visitors alike (Oliveira & Fogaça, 2021).
