Are you wondering if a simple rain barrel can lower your DC Water bill? You are not alone. Many homeowners hear about RiverSmart rebates and credits, but the steps and paperwork feel confusing. In this guide, you will learn how rain barrels qualify, the difference between a one-time rebate and ongoing bill credits, the exact photos and documents you need, and what to do if you live in Washington, VA or elsewhere in Rappahannock County. Let’s dive in.
Rebates vs. bill credits
RiverSmart rebates: up-front help
RiverSmart Homes programs provide rebates or cost-share funding to help you install green stormwater practices like rain barrels, rain gardens, and permeable pavers. These programs are run by the District’s Department of Energy & Environment and partners. They reimburse part of your installation cost after you apply and get approved. Check the current requirements and application steps on the official RiverSmart Homes page.
RiverSmart Rewards credits: lower future bills
RiverSmart Rewards is DC Water’s stormwater credit program. If you install qualifying practices, you can receive a credit on the stormwater portion of your DC Water bill. Credits are based on the amount of runoff you manage from your roof or other impervious surfaces. You must apply with documentation and, in some cases, complete an inspection. Review the latest rules on the DC Water RiverSmart Rewards page.
How the credit shows up
- Credits reduce only the stormwater line on your bill, not your water or sewer charges.
- Approval can take several weeks. After approval, credits typically appear on a future billing cycle and may be prorated.
- Some programs require yearly verification or re-inspection to keep credits active.
How rain barrels earn credits
A rain barrel captures water from your roof through a downspout. By holding that water for later use, it reduces how much stormwater rushes into the system during a storm. For credits, programs look at the roof area draining to the barrel and how much water your system can store. Your credit depends on that managed volume and the program’s approved calculation method. Always confirm the current formula and documentation on the program pages.
Plan and size your barrel
- Identify which downspout you will use and measure the roof area that drains to it.
- Choose a barrel or series of barrels that provide meaningful storage for that area.
- Plan a safe, stable base. A full barrel is very heavy.
- Design a clean overflow path that sends excess water to a pervious area away from your foundation and neighboring properties.
- Check local codes and HOA guidelines before you begin.
For general best practices, see the U.S. EPA’s guidance on rain barrels and Soak Up the Rain.
Install to qualify: key criteria
To qualify for rebates or credits, your installation should meet these common criteria:
- Direct roof connection: Attach the barrel to a downspout or approved diverter that receives roof runoff.
- Defined drainage area: Measure and document the roof area feeding the barrel.
- Adequate capacity: Provide storage that is appropriate for the area you plan to treat.
- Overflow to pervious ground: Direct overflow to lawn, garden, or a rain garden. Avoid hard surfaces and storm drains.
- Mosquito-safe and secure: Use tight-fitting lids and screens; secure spigots and connections.
- Durable and permanent: Place the barrel on a flat, stable pad and secure it so it will not tip.
- Maintenance plan: Be ready to clean screens, manage overflow areas, and winterize.
The step-by-step process
- Plan and size your barrel. Measure the roof area and pick the right capacity.
- Install to program criteria. Use a diverter or direct connection, add screens, and set a stable base.
- Gather documentation. Keep receipts, model specs, and photos as you go.
- Submit your application. Use the latest forms for the rebate and the DC Water credit.
- Prepare for inspection. Some programs accept photo reviews, while others visit in person.
- Receive your rebate or credit. Credits generally appear on future bills after approval.
- Maintain your system. Clean screens, check overflow paths, and winterize as needed.
What to include in your application
Strong documentation speeds approvals. Use this checklist to stay organized.
Application-ready photo checklist
- Wide shot showing barrel location relative to the house
- Close-up of downspout connection and diverter
- Photo of product label or specs showing capacity
- Photo of overflow path to a pervious area
- Photo of the barrel base or platform
- Photo of installer invoice or receipt
- Photos of measurements used for calculations, like roof dimensions
- Optional: photo of the barrel in operation during a storm or a safe staged test
Submission document checklist
- Completed program application form, signed
- Proof of DC Water account and property ownership or authorization
- Product specifications and purchase invoice
- Annotated site plan with measurements and the drainage area
- Photo set listed above
- Maintenance statement and permission for inspection if required
How to draw your site sketch
Keep it simple. A hand-drawn plan is fine if it is clear.
- Outline the property and house footprint.
- Mark the downspout feeding the barrel and draw the barrel location.
- Shade or label the roof area draining to that downspout with measurements.
- Draw the overflow path and where it discharges to pervious ground.
- Add a scale or at least key dimensions in feet.
Inspections, timelines, and common pitfalls
Many programs complete virtual reviews using your photos and sketch. Others schedule an on-site inspection to confirm the connection, sizing, and overflow. Reviews can take several weeks. Rebates are often paid after approval and fiscal processing. Credits typically post on a later billing cycle and may be prorated.
Common mistakes to avoid:
- Missing photos of the downspout connection or overflow
- Incorrect drainage area measurements
- Overflow directed to a driveway or storm drain
- Barrels without insect-proof screens
- Barrels on unstable bases
- Missing owner authorization for non-owner applicants
Maintenance basics
- Clean inlet screens and gutters regularly.
- Keep overflow areas free of debris and erosion.
- Check spigots and seams for leaks.
- Empty or disconnect and store the barrel before hard freezes.
- Keep a simple maintenance log with dates and tasks.

Will a single 50 to 100 gallon barrel qualify for a credit?
- Possibly. It depends on the roof area draining to the barrel and the program’s minimum sizing and capture thresholds. Check current eligibility rules before you buy.
Do I need a professional installer for a qualifying rain barrel?
- Not always. Many programs accept homeowner installations if they meet the criteria and include complete documentation. Larger systems may require licensed installers.
