3.1 (NYC Water Story Vocab) Flashcards
Watershed
an area of land that collects freshwater and drains or “sheds” water into a specific waterbody
Reservoirs
- above ground freshwater storage (lake, river, stream)
Aqueducts & Tunnels
method of transporting water from watershed to city
Disinfection
These facilities chlorinate
and add UV light to the
water to disinfect it before
drinking and household
purposes.
Municipal Pipes
The downhill flow of water creates enough pressure to shoot the water as high as six stories in most parts of the city without electricity
or pumping.
Water Sampling
Field scientists test the
water for lead and other
heavy metals, as well as
other indicators of water
quality such as pH and
turbidity (cloudiness)
Water Conservation
Use ONLY cold water for
drinking and cooking (hot
water is more likely to pull
lead from old pipes).
Down the Drain
Used water from sinks and toilets and stormwater from rain and snow enter here.
Combined Sewage System
- mixed heavy rain and snow fall
- During certain rain storms, the sewer system and wastewater treatment plants cannot handle the amount of combined sewage.
- discharges some of the combined sewage into waterways WITHOUT treatment
Wastewater Treatment
- Removed fecal and other wastes
- Primary Treatment: removes trash and large objects and then into chambers and tanks where smaller particles settle out
- Secondary Treatment: wastewater flows into large
tanks filled with microbes that break down organic wastes - End: goes through disinfection
Effluent
Cleaned effluent (waste) is discharged into a
waterbody.
Sludge
- The solids that are collected are processed in large digester tanks which act as stomachs.
- Once digested, the resulting sludge can be put to beneficial use as fertilizer, if it meets STRICT contaminant levels.
- If not, it is typically disposed of at a landfill
Aquifer
a body of rock and/or sediment that holds groundwater
underground reservoir
Groundwater
water held underground in the soil or in pores and crevices (cracks) in rock.
Well
a hole drilled into the ground to access water contained in an aquifer
