Wastewater systems are infrastructures that collect, transport, and treat water contaminated by human use. They are the hidden circulatory system of cities, mediating between sanitation, ecology, and public health. Increasingly, they are reimagined as ecological infrastructures where treatment and landscape coincide. Wastewater systems reveal how waste is managed, concealed, or metabolized in urban metabolism.
Parco della Pace is a transformation of a former airport into a vast ecological machine that operates simultaneously as water infrastructure, biodiversity habitat, and public space. Parco della Pace offers a complex interplay of geometries—traces of the former runway, the rigid grids of adjacent military grounds, and the superimposed logic of new water systems—generating a distinct spatial language that remains legible at multiple scales.
What distinguishes this project is its unapologetic embrace of scale, engineering, and earthworks, yet without sacrificing ecological subtlety. The site functions as a large-scale detention basin, integrating hydrological processes into a resilient landscape capable of absorbing and slowly releasing floodwaters. Water becomes both technical infrastructure and ecological mediator, generating new habitat edges and transitional ecotones that allow species to recolonize this former infrastructural void.
Beyond its technical accomplishments, Parco della Pace also offers a productive ambiguity between program and process. Today, it offers a base that is generous, extensive, and resolutely territorial in scale. In time, it will negotiate between the formal and the open-ended, between cultural programming and wilderness zones left to self-organisation. The project resists the impulse for total scripting, instead establishing a layered framework that will evolve across ecological time. In this sense, the park presents a form of engineered openness, where large-scale interventions initiate processes whose full resolution remains necessarily incomplete.
The book, Thinking Through Soil: Wastewater Agriculture in the Mezquital Valley, by Montserrat Bonvehi Rosich and Seth Denizen, came out last week, published by Harvard University Design Press. It is an enormous study, partly conducted through the Thinking Through Soil studio course at the GSD, Department of Landscape Architecture, and with the help of the […]
In Copenhagen’s new climate park form radically follows nature Copenhagen’s latest and most radical climate park, Grønningen-Bispeparken, transforms a derelict, barren grass area into a cohesive 20,000 m2 lush, playful, biodiverse, and art-filled urban nature park for all. Grønningen-Bispeparken is not a romantic promenade park but a transformative paradigm shift in urban development, where form […]
Sara Eichner is a visual artist and designer with a keen interest in data visualisations and cartography. She works with Geographic Information Systems (GIS) and programming languages like Python and uses design software to translate data into comprehensible visual stories. Her work is people-centred and she often uses data to represent less-heard voices. Eichner is […]
