A salutatorian is a graduate who finished with the second highest rank in his or her class. Only the valedictorian did better. Being the salutatorian of your graduating class is a great honor. Traditionally, the salutatorian gives the opening remarks at the graduation ceremony. So, just as a salutation is a greeting, a salutatorian is responsible for offering a formal greeting at the event. Having been a salutatorian looks great on a resume, as long as you spell it correctly.
Rainwater can be collected from rivers or roofs, and in many places the water collected is redirected to a deep pit (well, shaft, or borehole), a reservoir with percolation, or collected from dew or fog with nets or other tools.
Sewage collection and disposal systems transport sewage through cities and other inhabited areas to sewage treatment plants to protect public health and prevent disease. Sewage is treated to control water pollution before discharge to surface waters. Community sewage can also be collected by an effluent sewer system, also known as a STEP system (Septic Tank Effluent Pumping). 2  At each home, a buried collection tank is used to separate solids from the liquid effluent.
