Our home has a sump pump in the basement because of a high water table. As a result, the pump is sending a lot of water out through a pipe with an outlet about 30 feet from our house, near the edge of our property. My wife doesn't want that water to go to waste. She is interested in making a pond by the outlet where the water comes out of the pipe. As a test, she dug up a little area, and found that it fills up quickly with the water that our sump pump expels.
Is a pond a good use for this ground water? I'm concerned that the water might contain a lot of pesticides from our neighbors' lawns or other contaminants. That might make it risky to add fish, but if we don't add fish, a lot of mosquitoes could breed there. If you think a pond is feasible, how could we design an ecosystem that makes use of this water?
What other uses would you recommend for the water that our sump pump puts out?
