The City of Toronto has ordered us all to disconnect our eavestrough downspouts from their underground connections to storm sewers. That will keep rainstorms from overflowing the storm sewers and washing excess water and sewage into Lake Ontario. It will help to keep the water table, the underground water level, higher and withstand drought.
We are encouraged to add rain barrels as well to conserve rain water for watering lawns or plants. Hmmm, should the barrel be on a stand for gravity-fed watering?
