Water treatment field trip
Today we went to the Water Treatment Plant and the Wastewater Treatment Plant. First, we went to the lake to see what we thought was in our watershed. After we observed all the items that we saw in the water shed, we went to the Water Treatment Plant. While we were there, Ms. Drizzle and Sprinkle gave us a tour through the plant. We saw how the water gets clean and what they use to clean it. We also went under the plant and saw all the color coated pipes. The light blue pipes were the pipes that carried the water to the Water Treatment Plant. The black pipe carries the backwash to the Wastewater Treatment Plant where it is cleaned and put in Bellingham Bay. The dark blue pipes carried the clean water to your home. Then, we went to the Wastewater Treatment Plant. It really stunk! The reason it smelled so bad was because the water that you flush with, the water that you brush with, the water that you wash with all goes to the Wastewater Treatment Plant. The first thing we did was look at all the stages in the wastewater cycle. First, we saw what the water looked like when it came from our houses. Then, we looked at it when they put the water through the bar screen house. (They used a comb instead of a screen when we observed.) Next, they let if sit. After a couple hours, there were three layers. The bottom layer was sludge, the middle layer was waste water, and the top layer was scum. The items fell heaviest to lightest. Then they use a scum scraper to scrape off the scum and sludge. Then, we saw what the water looked like when they let the microorganisms activate. When they activate they clump together to eat. When you see what that looks like, it looks like little balls of dirt. If you let the microorganisms sit, they will fall to the bottom. Once they fall, a scraper will remove the microorganisms and put them in the incinerator. They water that was left will be put in Bellingham Bay. The incinerator is a place that they burn the scum, sludge at the microorganisms that activated. The incinerator burns at 1500 degrees fareinhight.
