Rainwater Harvesting Workshops

Lenny RWH System

Where Does Your Water Come From? Where Does It Go?
GCC Nursery, 431 Carroll St, Brooklyn, NY 11215
Sun, November 13, 11:00am - 12:30pm 

RSVP for a workshop here. 

Learn about what you can do to help prevent Combined Sewer Overflows in New York City. Whenever it rains, raw sewage is dumped untreated into New York City water-bodies like the Gowanus Canal. In this hands on workshop, learn about this problem and come away with ideas about what you can do from adopting a bioswale, to building your own rainwater harvesting system.

Pick up a FREE DEP Rain Barrel for your school, home, or business!*

*EDIT: We are currently out of stock. Sign up for the rain barrel waiting list here. We will email you as soon as a new shipment arrives.


In partnership with GrowNYC, GCC is building a modular Rainwater Harvesting System to capture rainfall at our compost and nursery site. The project will have multiple benefits of capturing rainwater used to irrigate plants, prevent pollution by minimizing combined sewer overflow, provide a shaded workspace for volunteers working on composting and plant propagation, and for school-age and adult visitors to participate in workshops and activities. It will also provide a way to get shelter from the rain and act as a demonstration of what homeowners and gardeners can do at their own site.

Lenny Librizzi is the Director of Green Infrastructure at GrowNYC. He has taught classes and workshops on Green Infrastructure, Water Conservation, Storm Water Management and Rainwater Harvesting, training individuals how to build rainwater harvesting systems and other stormwater management techniques including bioswales and rain gardens. He and his trainees have built over 150 rainwater harvesting systems, collecting over 1,500,000 gallons of water each year. He writes about Community Gardening and sustainability in his Community Gardening Blog.
