You are watching: Water is the essence of wetness

1 Water is the significance of wetness… And wetness is the essence of beauty. ~Derek Zoolander zoolander

*

2 You might have actually some questions… What is stormwater? Why perform civilization treatment around it? Why must I care about it? Is stormwater affecting me all the time? Are there times of the year once stormwater has greater effects? Do world of particular areas should be more came to about stormwater than others? Rest assured, together we will answer these questions and also more!

*

3 What is stormwater? Water that originates during precipitous events

*

4 Wright here can the water go?

*

5 Remember the Water Cycle Stormwater that doesn’t go right into the ground or retransforms to the setting is called Stormwater Runoff

*

6

*

7 The effect of led surfaces!!

*

8 Why perform civilization care about stormwater?...............2 factors 1. The water itself FLOODING!!!!FLOODING!!!! $$$$$$ Landslides

*

9 2. What’s in the Water Pollutants Nitprices Phosphates Heavy metals

*

10 Seasonal Effects!

*

11 Roadway Salt! We deice roadways in the winter using salt… NaCl Chloride ion (Cl-) is damaging to the environment and also can affect plant and wildlife.

*

12 Snow Melts in Spring Spring freshet Increased quantities of stormwater because of snowmelt in beforehand spring. Carries sediment and various other pollutants through it.

*

*

14

*

15 “Although the freshet occurs every spring, tright here is even more flow in some years than others. Throughout an average year, around two and a fifty percent billion pounds of sediment wash dvery own the Susquehanna into the Bay. In exceptionally wet years it can be twice that.”

*

16 2.5 billion lbs = approx 3 Realm State Buildings

*

17 Stormwater management! Sepaprice vs. linked stormwater and drain Swales and pipes Retention and also Detention Ponds Rain Barrels and Cisterns Eco-friendly Roofs Rain Gardens Permeable pavements

*

18 WASTEWATER Let’s work-related out the interpretation. How is wastewater various from sewage? Any water negatively impacted by huguy affect Subset of wastewater that has feces and/or urine

*

19 “In a wet 2006, even more than 1 billion gallons of untreated water was released right into the river” How does stormwater connect to wastewater?

*

20 Wastewater Management Sewer Systems Transport wastewater & sewage to the… Wastewater Treatment Plants (WWTP)

*

21

*

22 Old times!! Humans resided in little groups…waste wasn’t much of an issue

*

23 Messopotamia, Rome, & China People develop farming which enables for life in the city. Population densities increase = several waste in one location

*

24 London: A Case Study! In the days once London was still small, people dumped their waste external their windows! This ongoing for a time till someone said, “Gee, I really don’t like walking in my very own poo!” Pip-pip…Cheerio!

*

25 Sewage in London Sewers were built! BUT All wastewater was sent out to the Thames! By 1849 fish were eliminated! Between 1831 and also 1866: 4 cholera epidemics!

*

26

*

27 London, Lancaster, and Philadelphia Combined sewer: old mechanism designed to carry both sanitary waste and also surconfront runoff

*

28 OVERLOADING THE SYSTEM!!

*

29 OUTFALLS Where linked sewage system water and runoff is discharged right into rivers

*

30 Sepaprice drain and Stormwater Excludes surface runoff from sanitary waste

*

34 Google: “what happens after the flush” esa21.kenneobserved.edu/activities/ww.../ww-treat-after-flush-epa.pdf What happens after the flush?

*

35 (BMPs)

*

36 Swales A ditch that channels and also absorbs stormwater runoff. Slows stormwater’s entrance right into streams or lakes. The finest kinds are planted through native vegetation.

*

37 Swale Pics! Vegetated swaleSwale via dams

*

38 Retention vs. Detention Retention Ponds (Wet Pond) Detention Pond (Dry Pond) A Permanent, fabricated pond provided to host stormwater and also release it slowly. A artificial basin that holds water temporarily throughout heavy storms.

*

*

41 Rain Barrels Containers supplied by human being to capture stormwater that would normally run off their roof and also right into the storm drainpipe. Usual uses: Watering lawns Wash cars / clothes

*

42 Cisterns A LARGE container used to store water to be offered at a later time. Normally is underground

*

43 Green Roofs A structure that is partially or entirely spanned with vegetation. Advantages: 1. absorbs rainwater 2. insulation to house 3. habitat for wildlife 4. lowers urban air temperatures MORE COOL EXAMPLES

*

44

*

45 Rain Garden A sunken vegetated area used to collect and also store stormwater. Often offered near parking lots.

46 Permeable Pavements Surfaces led through materials that permit the passage of stormwater to the soil beneath.
