A San Rafael-based essential oils producer is offering free DIY rain barrels to Marin Water customers. EO Products is focused on sustainable manufacturing, including putting its manufacturing products back into use, and the donated barrels were previously used in its business operation.
These non-food-grade barrels can easily be converted into water storage barrels for use in residential and commercial rainwater catchment systems, enabling Marin Water customers to supplement their outdoor watering needs. With the free barrels, a few needed supplies and some DIY instructions, customers can create their own rain catchment systems at a reduced cost.

About the registration process
- Marin Water customers interested in receiving a free barrel should complete the form below completely and submit. Customers may request as many barrels as they need. While supplies are limited, Marin Water will do its best to provide the requested quantity to customers selected for the barrel giveaway.
- Each month, Marin Water will randomly select barrel recipients from the list of customers registered to receive the free DIY rain barrels. The number of customers selected each month will be dependent on the availability of the barrels.
