Information About Disconnect / Redirect Downspoutsĭownspout Disconnection, Green Infrastructure, U.S. Consider local regulations and where the water will be directed to avoid property damage, unsafe conditions or other potential problems.
Note: Downspout disconnection may not be appropriate for all locations. Redirecting downspouts to a landscaped area is a great way to help reduce runoff from a property. Water is then redirected to flow into a rain barrel or to a lawn or garden where it can soak into the ground. Downspouts may also be connected to a pipe in the ground that connects directly to the sanitary sewer or storm drain system.ĭownspout disconnection is the process of disconnecting the downspout from a pipe or the paved area. MAKE SURE DOWNSPOUT EXTENSIONS END AT LEAST THREE FEET AWAY FROM BASEMENT FOUNDATIONS, AND WATER IS BEING DIRECTED ON GROUND THAT SLOPES AWAY (DOWNWARD) FROM YOUR BUILDING.Downspouts are often directed onto a paved surface, such as a driveway, which sends water directly into the street when it rains.DO NOT ALLOW WATER TO SPLASH OR POND ON ADJACENT PRIVATE PROPERTY.FIRMLY ANCHORED SPLASHBLOCKS SHOULD BE INSTALLED IF DOWNSPOUT DRAINAGE IS TO TRAVEL OVER LANDSCAPING OR DIRT.DIRECT DOWNSPOUT EXTENSIONS AWAY FROM THE BUILDING TO PREVENT SEEPAGE INTO BUILDING FOUNDATIONS OR ADJACENT PROPERTIES.
#DOWN SPOUT INSTALL#
Secure extension with sheet metal screw or pop rivets.Ī) Plug top of drain hole with crumpled newspaper and fill to top with at least 1" of mortar cement.ī) Optional: Install a splash block to protect grass and shrubbery. Hold extension in place and drill a hole on each side. Secure with sheet metal screws or pop rivets.ī) Place the end of extension over elbow (length will depend upon installation). Distance will vary depending upon installation.Ĭ) Loosen mortar cement from drain tile, and remove lower portion of down spout.Ī) Place the larger end of elbow over edge of downspout, hold elbow in place and drill a hole in each side. 10" above the ground using a hack or sabre saw. Step1Ī) Drill a 1/4"hole in mortar joint and hammer stand-off bracket into wall attach the downspout.ī) Cut downspout appx. The following illustrations will demonstrate that the physical disconnection is relatively simple, inexpensive, does not require a permit, and can be accomplished with a minimum of inconvenience. When you are completed, your project should be a permanent solution which is beneficial to your grass, flowers, shrubbery and trees. Before you disconnect your downspout, consider where you are directing the water, and that cold weather will cause icing conditions. The City will continue and expand its efforts to educate citizens on the benefits of disconnecting existing downspouts and on alternative uses of stormwater.ĭownspout disconnection can help prevent basement sewage backup. Public service announcements, community meetings, instructional video tapes, brochures and discounts on materials for downspout disconnection have all been provided to homeowners.
The City actively encourages homeowners to disconnect their downspouts from the sewer system and direct the water instead to their yards or gardens. While impractical in some places (where there are only hard surfaces or where drainage could impact neighboring property), the potential to reduce basement flooding and increase natural infiltration is great. The effectiveness of the inlet control system depends on the number of roof downspouts that are disconnect-ed from the sewer system. This measure helps relieve the burden on the sewer system and reduce the frequency of basement flooding and combined sewer overflows into our waterways. Stormwater is detained on city streets for brief periods before flowing back into the sewer system. The system works by installing restricters to slow the flow of stormwater into the sewer system. The City of Chicago was the first major metropolitan area in the country to successfully implement an inlet control system to relieve basement flooding.
