Experimentation Using PERT/CPA – Building an artificial waterfall to increase DO
Implementations:
Aeration: In order to increase the dissolved oxygen in the water which will
therefore increase the amount of oxygen supply to the lobsters, raising their
population, we will construct ten artificial waterfalls underneath the Throgs Neck
Bridge (as well as in Oyster Bay, Great Neck and Long Beach) similar in design to the
one on the Brooklyn Bridge in order to create faster moving water and increase
turbulence (falling water traps air, therefore trapping oxygen and adding it to the
LIS) while simultaneously cooling the water. In addition, these waterfalls will cool
the Long Island Sound by collecting the water from the Sound and storing it in solar
powered cooling tanks until the water is cool enough to return to the LIS. We will
construct ten of these waterfalls throughout the Sound, primarily concentrated in
the Western Section, and let them run for ten years and see if the effects are
beneficial enough to continue to construct more or to see if they are effective
enough in that quantity.

 Get an estimate of how much it will cost to build this waterfall - 1 month
 Find sponsors, Create a website that has a donation section, Find investors to
invest in our cause, apply for grants – 5 years
 Hire engineers - 6 months
 Figure which is the safest, most cost efficient way to construct the waterfall 5 months
 Find a way to power the waterfall (green/renewable energy resources) - 3-4
months
 Design filter pools to filter the water that will be used for the water - 3
months
 Research: the waterfall will not cause any harm to the environment, wont
change LIS ecosystem - 1 year
 Get a permit from NY state government to build the bridge - 5 months
 Hire contractors - 2 months
 Hire workers - 2 months
 Hire environmental consultants to make sure waterfall is eco friendly – 2
months
 Give money to workers to get materials (pipes, scaffolding, pumps) - 2
months
 Close off the area for construction and get base of waterfall in – 5 months
 Construct waterfall – 1 year
 Have the opening ceremony for the waterfall (get the public more aware and
involved during this ceremony) – 1 Day
 How big should the waterfall be? 135 feet tall, 90 feet wide

What times should it run? From 7am-9pm
