Although you may think that weather and climate change seem to have little to do with each other - they are two different things in themselves! However, according to the research of NEW YORK CITY STORMWATER RESILIENCY PLAN, climate change has been unpredictable and will interfere with all aspects of our life in New York in the coming decades. According to the previous blog, extreme weather such as heavy rain has become more intense and frequent in New York. Of course, the harm to people's lives is not only "sea level rise" and "the mainland where people live is submerged", but also more inclined to tidal flooding and coastal flooding (of course, these are also potential dangers for coastal cities like New York, see the previous blog for details). Stormwater flooding has more obvious interference to people's lives.
Stormwater flooding, as its name implies, is caused by daily heavy rainfall, which is due to the increasingly frequent heavy rainfall caused by global warming - this is an external cause. Another internal reason is the Combined Sewer Overflow (CSO) caused by the backwardness of the sewage system due to the aging of urban infrastructure.
Combined Sewer System (CSS) is the sewer system used in New York. It is a sewage system that collects local rainwater, household wastewater and industrial wastewater and then outputs them through the same pipe. However, when flooding comes, the water will exceed the capacity of CSS, which will lead to the pollution of water source due to the untreated wastewater directly overflowing into the nearby rivers through pipes. The combined sewer system (CSS) carrying rainwater, domestic sewage and industrial wastewater may be flooded by rainwater and melted snow. These CSS can discharge untreated waste into nearby water bodies through combined sewer overflow.

At this point, you may have a fluke mentality: Ha! What do these phenomena have to do with me? Maybe I live in the community of the separate sever system!
However, according to the report of NEW YORK CITY STORMWATER RESILIENCE PLAN, 60% of New York's communities are such CSS, so CSOs have become a circular environmental damage caused by climate change and aging infrastructure that cannot be ignored in cities.
Therefore, in addition to strengthening the replacement of sewage systems into separate sewage systems, strengthening urban Green Infrastructure (GI) is also one of the solutions for long-term and sustainable development. GI practice helps to control rainwater at the source, remove pollutants, and reduce rainwater runoff and the amount of waste ultimately flowing into the sewer system and local water bodies.
So pay attention to every rainfall around you, pay attention to the ecology around the wells when walking, and pay attention to the garbage washed by rain at the roadside... They may become a toxic element in your daily water or white garbage floating in front of your door.
