Urban centers across the globe face an escalating ecological crisis as rapid expansion replaces permeable soils with asphalt, concrete, and stone. When heavy rains arrive, these impervious surfaces prevent natural water absorption, leading to catastrophic urban runoff, overloaded drainage infrastructure, and severe flooding. Addressing this pressing challenge at a human scale, architecture studio El Sindicato Arquitectura has introduced Yaku—a modular urban furniture and sustainable runoff management system installed in Isla Tortuga Park in northern Quito, Ecuador.
Derived from the Kichwa word for "water," Yaku is designed to bridge the gap between hard municipal infrastructure and ecological consciousness. Rather than merely channeling stormwater away through hidden subterranean pipes, the Yaku module actively engages with the natural water cycle above ground. The prototype functions as a multi-functional public amenity that captures precipitation, temporarily stores it, and facilitates controlled ground infiltration. Simultaneously, it serves as a gathering space that encourages citizens to interact with public infrastructure, fostering a deeper awareness of urban ecology and water conservation.
Key highlights of the Yaku project include:
Location: Isla Tortuga Park, northern Quito, Ecuador.
Structural Typology: A modular design engineered for versatile installation across diverse urban surfaces.
Cultural Integration: Fosters public community engagement while educating citizens on the critical relationship between urban form and natural hydrological cycles.
Chronology of the Project
The journey of the Yaku module from a theoretical concept to a tangible urban intervention reflects a methodical approach to sustainable landscape design and public architecture in high-altitude Andean environments.
Phase 1: Conceptualization and Contextual Analysis (Pre-2026)
Quito’s unique geography—stretched across valleys and steep Andean slopes—makes it acutely vulnerable to erratic rainfall patterns and heavy runoff. El Sindicato Arquitectura identified a critical deficiency in how public spaces managed micro-drainage. Traditional urban planning in the city routinely relied on rapid evacuation systems, which exacerbated downstream flooding risks. The design team began conceptualizing a decentralized, nature-based solution that could intercept water close to the source while simultaneously adding public value to underutilized parks.
Phase 2: Prototyping and Engineering the Module
The design phase focused heavily on modularity and adaptability. The architects needed a structure that could be deployed on varying topographies without requiring heavy, disruptive civil engineering works. Engineering efforts concentrated on internal filtration layers, structural durability against UV radiation and high-altitude weather conditions, and intuitive integration with pedestrian pathways. The name Yaku was chosen to honor indigenous Kichwa roots, embedding cultural stewardship into the material reality of the design.
Phase 3: Installation at Isla Tortuga Park (Mid-2026)
Isla Tortuga Park in northern Quito was selected as the pilot testing ground due to its high pedestrian traffic and existing surface runoff vulnerabilities. Installation took place with minimal disruption to the surrounding parkland, showcasing the non-invasive nature of the modular system. Upon completion, the site transitioned into an active testing and gathering space, allowing the architects, municipal planners, and the public to observe the module’s hydrological and social performance in real-world conditions.
Supporting Data: Urban Hydrology and Nature-Based Solutions (NBS)
To fully grasp the significance of El Sindicato Arquitectura’s intervention, it is essential to contextualize the challenges of urban hydrology in modern Latin American cities.
The Impervious Surface Problem
According to urban planning and environmental studies, a typical city block with 75% to 100% impervious cover generates nearly five times the runoff volume of a typical woodland of the same size. In Quito, where sudden downpours are common, surface runoff overwhelms storm sewers, washes pollutants directly into local ravines and rivers, and strips urban soils of essential moisture.

Historically, cities have responded to stormwater management through massive, capital-intensive gray infrastructure projects—such as deepening riverbeds or constructing enormous underground retention basins. However, contemporary urban resilience strategies increasingly favor Nature-Based Solutions (NBS) and decentralized interventions. By distributing smaller retention and infiltration units like Yaku throughout a city’s network of parks and plazas, municipalities can significantly flatten peak runoff curves while enhancing localized biodiversity and microclimates.
Official Responses and Design Philosophy
The design philosophy driving Yaku centers on the democratization of ecological infrastructure. El Sindicato Arquitectura approached the project with the belief that municipal systems should not be hidden away from public view, but rather integrated into the daily lives of citizens.
"Isla Tortuga Park provided the ideal canvas to test a philosophy where infrastructure and public space are no longer mutually exclusive," notes the design team behind El Sindicato Arquitectura. "By transforming a technical necessity—managing urban runoff—into an inviting piece of public furniture, we shift the public perception of water from a hazard to be drained into a vital resource to be celebrated."
Urban design critics and local municipal stakeholders have praised the project for its dual functionality. By merging landscape architecture with practical civil engineering, Yaku demonstrates that climate-resilient interventions do not require sterile, industrial aesthetics. Instead, the module uses warm materiality, ergonomic seating geometries, and visible hydrological pathways to spark curiosity and dialogue among park-goers. When children and adults sit near the module, they are subtly reminded of where rainwater goes, how it filters, and why maintaining soil permeability matters for the health of the entire urban basin.
Implications for Future Urban Planning
The successful deployment of the Yaku module in Quito carries profound implications for urban resilience planning, particularly across Andean and Latin American cities facing similar topographical and climatic pressures.
1. Replicability and Scalability
Because Yaku is designed as an independent, modular unit, it is not bound to the specific geometric constraints of Isla Tortuga Park. The system can be scaled up, duplicated, or reconfigured to fit tight street corners, school courtyards, transit plazas, and linear parks. This scalability lowers financial barriers for municipal governments looking to implement green infrastructure without launching multi-million-dollar civil works.
2. Shifting Public Consciousness
Physical infrastructure shapes cultural attitudes. For generations, urban water management has been treated as an out-of-sight, out-of-mind utility managed exclusively by municipal engineers. Yaku actively brings hydrology into the public realm. By making the water cycle visible and interactive, the project helps cultivate a generation of urban dwellers who understand watershed health, climate adaptation, and the importance of sustainable resource management.
3. Integrating Indigenous Wisdom with Modern Design
By naming the module Yaku—invoking the Kichwa word for water—El Sindicato Arquitectura honors ancestral relationships with nature. Modern sustainable architecture is increasingly finding that traditional ecological knowledge, when paired with contemporary computational design and environmental engineering, yields the most resilient and contextually appropriate solutions.
As cities worldwide race to adapt to the unpredictable realities of climate change, interventions like Yaku offer a hopeful blueprint. They prove that tackling complex planetary crises—such as urban flooding and ecological degradation—can begin at the most local, intimate scale: a bench in a neighborhood park where people gather, rest, and watch the rain soak gently into the earth.
