Rainwater harvesting reduces the volume of water that enters the municipal storm sewer system during wet weather, which frees up capacity for conveyance, storage and treatment in downstream stormwater infrastructure. It also conserves treated drinking water which provides cost savings to municipalities through reduced demand for municipally-supplied water and to property owners through lower water bills. | Rainwater harvesting reduces the volume of water that enters the municipal storm sewer system during wet weather, which frees up capacity for conveyance, storage and treatment in downstream stormwater infrastructure.
