Downspout disconnection reduces stormwater in the sewer system.
Roof downspout disconnection.
Downspout disconnection is the process of disconnecting the downspout from a pipe or the paved area.
Downspouts may also be connected to a pipe in the ground that connects directly to the sanitary sewer or storm drain system.
Drill a hole on either side of each fitting and screw in a sheet metal screw to secure the fitting.
Disconnect and help keep excess water out of sanitary sewers.
This prevents stormwater from directly entering the storm sewer system or flowing across a connected impervious surface such as a driveway that drains to a storm sewer.
Some downspouts cannot be disconnected.
This reduces the amount of directly connected impervious area in a drainage area.
If necessary use needle nosed pliers to crimp the old downspout pipe so it slides into the new elbow.
Use similar downspout material or use adapters to change to plastic pipe.
Downspout disconnection is the process of separating roof downspouts from the sewer system and redirecting roof runoff onto pervious surfaces most commonly a lawn.
