Rain harvesting in a row house?
Committed gardener considering downsizing in from the 'burbs to a small rowhouse in the city. In my current detached single family home I'm now able to modify downspouts to divert rainwater into barrels. However it seems like it would be disallowed to cut into a downspout shared between two rowhouses. This is a photo of the front, downspout marked in red--I assume because the roof slopes in both directions that there's an identical one on the back. Looks like these downspouts go directly into the ground. Is the water sent directly into the storm drain system?
