What’s the Problem, and Why Does It Matter?

Approximately 40% of Hartford’s land area is comprised of impervious surfaces, and much of the remaining area is covered with clay-heavy soils with low infiltration rates. Impervious surfaces prevent rain from being absorbed into the soil underneath, resulting in excess stormwater runoff and causing added burden and stress on the city’s aging infrastructure. Hartford has a 150 year-old combined sewer system, which means that rainwater combined with wastewater can exceed the system’s capacity during storm events, resulting in discharges of untreated wastewater through combined sewer overflows (CSO).

More than 1/2 billion gallons of untreated wastewater overflow to local streams and waterways annually. These discharges impact the Connecticut River’s water quality over a 30 mile distance up to 50 times per year – every time it rains more than 0.25 inches. Other areas that have impaired water quality as a result of these CSOs include: Wethersfield Cove, North Branch Park River, Trout Brook, Goff Brook, among others. In addition, local basements and streets may experience backups and flooding of raw sewage as well.

What’s the Solution?

Green infrastructure (GI) is an alternative approach to stormwater management that protects, restores, or mimics the natural water cycle, using water as a resource. Widespread adoption of GI techniques can help reduce the cost of eliminating sewer backups and localized flooding, while providing many co-benefits such as cleaner air, cooler city streets, increased public green space, and enhanced wildlife habitat, all of which improve the quality of urban life. One cost-effective approach to green infrastructure is installing a rain barrel.

Installing rain barrels located in the combined sewer areas of Hartford is a low-cost approach recommended in the EPA Next Steps Memo. Homeowners can separate their roof downspouts from the combined sewer system and redirect roof runoff into a rain barrel, which can be used to water lawns and rain gardens. This approach, which has been successfully implemented by other cities around the country, reduces inputs to the combined sewer system while also absorbing excess runoff.

How Can You Help?

NOTE: For the 2019 phase, rain barrels were distributed at pickup events through September to November. The next pickup events will be in Spring 2020, and people will be invited in the order they sign up (as supplies last, and with Hartford priority). 

To help encourage residents to install rain barrels, the Office of Sustainability’s Green Infrastructure Team partnered with the Metropolitan District (MDC) in 2018 to bring FREE rain barrels to Hartford residents. In 2019, we were able to bring back the program with the support of the National Fish and Wildlife Foundation’s Long Island Sound Futures Fund. To date, with these partners and with the help of Keney Park Sustainability Project, the Youth Services Corps (YSC), and Our Piece of the Pie (OPP), over 300 rain barrels have been distributed among residents from across the city. For photos from our events, check out our twitter page @hartfordclimate. Many thanks to all of our partners at the MDC, OPP, YSC, CIRCA and the Hartford Department of Public Works that helped make this happen.

In 2020, there will be a new round of distributions in Spring, and this phase may also include a limited supply of other green materials such as trees and composters (Hartford resident priority). Please sign up in advance to get your name on the list for a rain barrel and potentially other green materials (as supplies last). Use the form below to sign up:

Frequently Asked Questions (FAQs)

  1. How does a rain barrel save me money? Rain barrels capture rainwater, which you can use to do things like water your lawns or wash your vehicle. During peak summer months, you could save about 1,300 gallons of water, and using rainwater means that you don’t have to spend more by paying for that water. Please refer to the Seattle Rain Barrel guide for very helpful information on when and how to use your rain barrel.
  2. When will my rain barrel be ready? We wrapped our 2019 pickups and are prepping for 2020. You will be notified of your pickup date in the order that you signed up (as supplies last). Note that when you pick up your rain barrel, you must have some proof of residency (ID or mail with your address on it).
  3. Do you deliver? We do not offer delivery at the moment, instead the rain barrels will be available for pickup at the North End Senior Center (80 Coventry St.). Pickup details will be sent to registered participants in the order that they signed up.
  4. How do you install a rain barrel? Installing a rain barrel is a fairly easy Do-It-Yourself task. Check out the Resources section below for more information.
  5. Can you install the rain barrel for me? We do not install rain barrels, but installing a rain barrel is a fairly easy Do-It-Yourself task. Check out the Resources section below for more information.
  6. I rent my home. Can I still sign up? Yes, other than being a resident of an eligible town, there are no requirements to receive a rain barrel. Note that if you’d like to connect the rain barrel with your home’s roof leaders, you’ll need to receive your landlord’s permission to install the barrel.
  7. Can I have more than one rain barrel? Glad to hear that you’re interested in installing more than one barrel. We have initially given out more than one rain barrel to our participants, but to the great demand for these materials, we may choose to only provide one barrel per eligible property. However, let us know, and we can keep you on the list for additional rain barrels should they be available.
  8. How big are the rain barrels? The barrels are 2 feet in diameter and 3.25 feet in height. They have a 55 gallon capacity. For photos, click here.
  9. When is the last day I can sign up? This phase of the Retain the Rain program will wrap up at the end of April 2020. 2019 pickup dates have been completed, and 2020 dates haven’t been determined yet. However, we strongly suggest that you sign up as soon as possible. We invite people to the distribution events based on the order they signed up, so it’s important that you indicate your interest in advance.
