2024 Rain Barrel Sale

Rain barrels are containers that capture rainwater for later use in your garden, house plants, or to wash your car. Rain barrels effectively reduce the amount of rainwater that reaches the city’s sewer system and can help prevent the occurrence of drainage backups. City-wide use can help reduce flooding, as every gallon captured matters. The barrels also reduce pollution by capturing water that would otherwise mix with pesticides and automobile fluids that eventually flow to the river.

There will be a pickup day event held on Saturday, May 18, 2024, at Gardens Gate – 611 Dayton Road, Ottawa, IL 61350 between 9:00 a.m. and 12:00 p.m. Rain barrels will not be sold at this event. They must be preordered.

The City of Ottawa Rain Barrel Program is consistent with city’s Combined Sewer Separation Long-term Control Plan, the Ottawa Flood Commission’s Campaign for Public Information, and the Ottawa is Blooming Committee’s environmental initiatives.

The Ottawa is Blooming Committee is tasked with helping Ottawa blossom through gardening, recognition of historic preservation efforts, celebrating Ottawa’s culture, promoting the arts, and implementation of environmental stewardship and projects.
