Since 1980, 32% of certified commercial shellfish farming areas in Puget Sound have a total area of ​​140,000 acres and are partially or completely closed due to water pollution.

Rainwater is the term used to describe the water produced during a rain event. Rainwater that is not flooded on the ground becomes a surface runoff, directly or indirectly goes through a rainwater pipe and a drainage port into a waterway. All rainwater is not being handled in the local waterway

Introduction Managing the outflow of rainwater and its influence is a serious problem faced by many communities in the western North Carolina province and nationwide. Citizens complain that flooding spills have led to floods and state and federal governments are forcing regional rainwater plans to manage rainwater contamination. Rainwater can be discharged into streets and artificial drainage systems, including rainwater drain pipes and underground pipes commonly called "sewer pipes". These sewers should not be confused with hygiene sewers that transport humans and industrial wastewater to the treatment plant. I reached the river. Rainwater entering the rainwater pipeline usually does not receive any treatment before entering the creek, lake and other surface water. The rain here flows to the Broad River of France, then to the Tennessee River and then to the Mississippi River, which eventually flows to the Gulf of Mexico.

Where will the rain flow when the rain enters the rainwater pipe? (Answer: After entering rainwater pipes, rainwater usually enters rainwater ponds, rivers, lakes, which is also known as surface water and finally enters the ocean.Original streets are rainwater and sewage systems Next, water is first sent to a sewage treatment plant where it is treated / purified and returned to the surface water ecosystem.How to reduce rain, rain, lake, pond, rain entering the sea (Answer: Use low-impact development and green infrastructure (GI) technology to reduce the outflow of rainwater from sources and to develop hydrology and water quality from the development site to the state before development You can recover

How does water permeable pavement reduce outflow of rainwater and pollution affect downstream ecosystem? (Answer: Reducing the amount of water that enters the traditional rainwater infrastructure system will limit the amount of pollutants entering the downstream ecosystem.The permeable pavement will reduce rainwater runoff by promoting rainwater infiltration ) This course was developed by the University of Water Conservation Research University in South Florida.
