Week 7 - Designated Tasks
Week 6 and Week 7 Goals and Tasks:
Scott - Finish up the information for compatibility for solar panels with the pump and filter system
Michael - Creating the parts of the apparatus in Creo - specifically pump
Patrick - Drawing filter system in Creo
Katie - Fixing up the blog and working on the tank in Creo
Alex - Fixing up the blog and working on the tank in Creo
Laura - Starting rough draft for final proposal and making sure all requirements are followed
Once all of the parts are created in Creo, we will combine them and make a working system.

Tank Information - Continuation of Week 6
Tank Information:
After
doing extensive research, we came to the conclusion that males need two gallons
of potable water per day, while females need one gallon of potable water per
day. This is an average of one and a
half gallons of water per person, per day.
Therefore, we would get a 165 gallon tank, which would provide for
around 100 people. The motive for
switching from stainless steel to plastic is for a number of reasons. First, cost and size have a tremendous impact
on the tank. The stainless steel tanks
found are cost to size efficient, but the size was comparable to a house. A big tank would decide the complexity of the
filter and the pump system. Therefore, a
smaller tank would be best, since this project will start small and progress
can be made if it turns out to be successful in Africa.
The new plastic tank found is 65
gallons, which is much smaller compared 793 gallons. One of the benefits of a stainless steel tank
is its ability to keep water cool.
However, the water pumped from the Nile into the tank will be warm
anyway, and there is not an air conditioning system within the tank, so the
ability to keep the water cool is irreverent.
The plastic tank will develop bacteria growth over a long period of
time, but since the tank will be completely emptied by the end of the day,
according to calculations. Therefore,
the plastic tank will be sufficient for the criteria this project
includes. Below is a picture of the
website the plastic green tank is purchased from, totaling to 149.99 dollars. The 793 gallon stainless steel
tank was 880.00 dollars. By changing to
the new plastic tank, over 700 dollars will be saved. Since the tank is plastic, there will need to
be some type of covering the tank can be stored under to be protected from
direct sunlight.
Below is a picture of an autoCAD multiview drawing from the website listed below. This is the website we would purchase the tank from: http://www.plastic-mart.com/product/6025/65-gallon-vertical-water-storage-tank-crmi-65vtfwg
The image below is a picture of the 65 gallon, green tank.

65 Gallon Vertical Plastic Water Storage Tank:
• This 65 gallon fresh water storage tank is designed for storage of potable water.• 65 gallon CRMI water tank is manufactured from Food and Drug Administration approved and compliant linear polyethylene with U.V. inhibitors and designed for the containment of liquids of up to 1.0 specific gravity.
• Tank features a vented lid and comes standard with female threaded inlet/outlets
• 65 Gallon water storage tank can be ordered in green or black polyethylene plastic
Water Tanks are for storage and are not designed to be pressurized. Tanks are designed for water storage use only.
Lid Size: 8"
Inlet: 1"
Outlet: 2"
Polyethylene plastic tanks are preferred for economical and chemical resistant attributes in alage growing system and bio-diesel process and storage. http://www.tanksystems.com/
These water tanks will last over 25 years and are approved by the FDA for potable water storage. UV inhibitors are built into the plastic to protect it from the sunlight. The colors available help to discourage algae growth. This tank is available through Loomis Tank Centers and also Plastic-Mart; both places sell the tank for roughly the same price.
