Water Management and Urbanization Concepts

Gray water is characterized as:

• water that has come into contact with fecal matter

• pure drinking water

• water recaptured from drains that contains soap and cooking oils

• rainwater collected from roofs

Which of these is an advantage of urban development?

• increased pollution

• mass transportation reduces number of vehicles on road

• more water consumption

• higher energy usage

What is a major impact of urbanization on the water cycle?

• decreased need for water

• better natural water filtaration

• increased surface runoff

• improved groundwater recharge
