find its way back into the earth. Instead, it is channeled

This often results in CSOs ("combined sewer overflows"), which cause untreated waste-water to discharge directly into local waterways.
The use of "green infrastructure", gradually being implemented through PlaNYC and other programs, can help to mitigate this problem. By storing these excess flows for slower release back into the environment, or for future use, which can also be thought of as "yields".
But until such strategies become more widespread, every time it rains, it's like leaving money on the table!
Hmmm. . . .maybe clouds really do have silver linings!
