    About

    GLOwanus is a public art project designed to inform Gowanus residents about water quality in the Gowanus Canal. When GLOwanus flashes, it’s signaling that untreated wastewater is polluting or has recently polluted the Canal. 

    The recent rezoning of Gowanus will bring approximately 20,000 new residents to the neighborhood, yet the local water management system is already past its capacity. The Gowanus Canal is a site for Combined Sewer Overflow (CSO) which requires new sewage containment plants to be built around the canal. But in the years before these are completed, a shift needs to occur in public education, awareness, and participation around water quality issues.

    Designed by Brooklyn-based artists Manav Singla and Ridima Jain, GLOwanus is a small lantern that cycles through different colors when the Gowanus Canal is under a City-issued waterbody advisory — meaning there’s a good chance CSO has recently spilled or may soon spill into the Canal. Placed in homes and businesses near the Canal, GLOwanus alerts people to this serious environmental issue. Using less water in your home or business, especially immediately before and during rainstorms, is one way to help reduce the level of CSO.

    The GLOwanus team is led by Gowanus residents Francesca Bastianini and Steven Koller, two fellows from Van Alen Institute’s Neighborhood Design Fellowship program with continued support from Van Alen. They’ve built on their experience in the fellowship to develop the GLOwanus light installation, paired with an information campaign with tips on how to help prevent CSO and hold authorities accountable for the Canal’s cleanup.

    Currently, our storefront windows are displaying information about CSO with illustrations by Martha Hall— stop by to learn more about this issue.

    GLOwanus lamps are programmed by an open source code developed by Stuart Lynn.

    What is CSO?

    CSO, or Combined Sewer Overflow, occurs when New York City’s water management system is overwhelmed by rainwater. To learn more about CSO and how this project hopes to raise awareness within the Gowanus community, we spoke with Steven Koller, a Neighborhood Design Fellow and an Environmental Science and Policy PhD student at The University of Miami. He explained:

    “New York City has a combined water management system, partially due to the fact that it’s quite an old system. 60% of the city’s water management is combined, meaning that when you flush the toilet, take a shower, or wash your dishes, all of that water gets combined into the same pipe as the water that’s flowing off the street via grates. Most of the time, that’s not an issue. But when you have a rain event — and it doesn’t need to be a big one — the system gets overloaded.

    “And this water is normally tied to a wastewater treatment plant, of which there are quite a few around the city. But during these rain events, the system can’t pump it all to the wastewater treatment plant. And so it’s released to roughly 700 outfall points around the city in all five boroughs, including at the head of the Gowanus Canal at Butler Street. On average, the canal receives roughly 270 million gallons of CSO annually.”

    Timeline

    Apr – May 2022

    Community Workshops

    Residents and students from Gowanus will learn about how water works through natural systems and city infrastructure to impact our daily lives, and how they might impact our lives in the future. Participants learn how to advocate for change through a better understanding of the problem, knowledge of where they can have an individual impact and where they have an impact at the community level.

    Oct – Dec 2022

    Installation Prototype

    Van Alen Institute will exhibit a prototype of the light installation in our storefront windows at 303 Bond Street.

    Jan – Dec 2023

    Community-Wide Installation

    The light installations will be distributed to residents and businesses in the Gowanus community, raising awareness of water quality throughout the neighborhood.
