This program is aimed at Chambly residents (owners of a residential, institutional or industrial building) who have purchased a rainwater barrel over the current year. Only rainwater barrels that have been commercialized and certified are eligible for the subsidy program. Note that creating your own rainwater barrel does not qualify for the subsidy. The subsidy amounts to $25 per barrel, for a maximum of two rebates per property. The subsidy application must be accompanied by a proof of residence, as well as the original bill of sale (including the name and contact information of the retailer, and the date of purchase), and be submitted before October 31 of the current year. You can download and fill out the form on the Web site (Environnement/Subventions), then submit it to the Public Works Department.
