Rain barrels are containers designed to capture and store rainwater that runs off a roof through a downspout. This collected water is used for non-potable purposes like watering gardens or washing cars, conserving municipal water supplies. The investment for a rain barrel system varies substantially, depending on the unit’s size, material, and necessary hardware.
The Cost of Rain Barrels by Type and Capacity
The barrel’s capacity is the most significant factor determining the initial expense, with larger units naturally costing more. Standard residential models typically hold between 40 and 60 gallons. A basic plastic polyethylene barrel in this size range generally costs between $95 and $140. These entry-level options are usually round or flat-backed to sit flush against a house wall.
The material and design greatly influence the price, separating basic collection units from decorative options. Simple plastic barrels are the most economical choice, sometimes retailing for as low as $70 for a 50-gallon model. Barrels designed to mimic wood, terra cotta, or stone are significantly more expensive, with decorative 50-to-65-gallon units often priced between $200 and $400 or more.
Larger storage needs may require a high-capacity rain tank, sometimes called a cistern. A system that connects multiple barrels provides a modular and often more cost-effective way to increase total water storage than purchasing a single large unit. Purchasing a complete rain barrel kit, which includes the barrel, spigot, and basic fittings, is typically priced slightly higher than buying just the empty shell.
Necessary Accessories and Installation Costs
The purchase price of the barrel is only one part of the total project cost, as several accessories are necessary for proper functionality.
A downspout diverter channels rainwater from the gutter into the barrel. It also filters out debris and redirects excess water back into the downspout system. These diverter kits, if not included with the barrel, typically cost an additional $30 to $90 and are essential for a closed-loop, mosquito-proof system.
Elevating the barrel is required for gravity to provide sufficient water pressure for filling a watering can or running a short hose. Pre-made rain barrel stands or pedestals, constructed from durable plastic or wood, are available for approximately $50 to $115. Alternatively, users can construct a less expensive DIY base using materials like cinder blocks or repurposed lumber to achieve the necessary elevation.
For homeowners who wish to maximize their water collection, linking kits are needed to connect multiple barrels in a series, creating a single, larger reservoir. These linking kits, which include the necessary hoses and connectors, generally range from $10 to $25 per connection. If professional installation is chosen, hiring a handyman or a plumber to cut the downspout and connect the diverter adds a labor cost. This labor typically falls between $45 and $200 per hour, depending on local rates and the complexity of the setup.
Reducing the Net Cost Through Rebates and Programs
The final net cost of a rain barrel can be significantly reduced by utilizing various conservation programs offered at the local level. Many municipal water utilities or regional water management districts provide rebates to encourage residential water harvesting. These programs are geographically specific and vary widely, sometimes offering a fixed dollar amount, such as up to $55 for the purchase of qualifying barrels.
Other programs offer incentives based on the system’s capacity, often providing a rebate of $0.50 to $1.00 per gallon of storage capacity up to a predetermined maximum cap. For example, some city programs may offer up to $400 per property, which can cover the entire cost of a basic rain barrel system. Consumers should consult their local water utility’s website to check for current rebate eligibility, application guidelines, and specific requirements.
In addition to direct rebates, some state or local governments offer tax incentives related to water conservation equipment. These incentives can include an exemption from sales tax for rainwater harvesting components or a property tax exemption for the value added by the system. These financial incentives lower the barrier to entry, making the investment in a rain barrel system more appealing.
