Storm water overwhelms our city’s sewage system. This results in residential and commercial waste water being dumped into fresh waterways before being treated- causing pollution. Bioswales use engineered soils, absorbent plants, and porous concrete to slow the rate of storm water flowing into the sewer. This gives the sewers time to drain properly and waste water gets treated as it was intended- avoiding excess water pollution. Passive infrastructure like bioswales reduce human impact on the environment while using few resources to upkeep and are therefore a perfect example of green building.
