Our team built a drainage system for a set of 3 water tanks that is designed to filter out dirty water.  


Materials Used:

- RIDGID AC11301 Water Pump

- 4 Tubaware Sterilite Clear

- Sensor Light


- String

- Wood shaped like cork

-Rubber Washer

-Dap Marine Sealant Silicone

-3 Plastic Hexscrew Drainage Joints

- Wires

-Plastic tube / hose

-Solid State 12 vdc 


-2 Funnels


 How To Build:

1. Take 1 clear Tupperware container and cut a hole at the bottom to fit the  shape of the water filter. (From now on I will refer to the Tupperware Containers as Tank.)

2. Insert the water filter and then seal it with the marine silicon sealant. Let it cure for 24 hours (This will be called Tank 3).

3. Get another Tank. We will call this Tank 1.

4. At the top of Tank 1 drill a hole to fit the shape of the Funnel.

5. At the bottom of Tank 1 drill a hole to fit the shape of the Hex Drainage Joint. (From now on I will use HDJ for Hex Drainage Joint).

6. Get another Tank. This will be called Tank 2.

7. Drill a hole at the top of Tank 2 to fit the HDJ.

8. Connect Tank 2 and Tank 1. 

9.  On the side of Tank 2 drill a hole to fit the funnel. 

10. Insert funnel

11. On the side of Tank 2 take a piece of Styrofoam and glue it on the outside. Do this to the opposite side you just placed the Styrofoam on.  

12. Make a hole to fit the laser on one side, and the sensor on the other. 

13. Glue the sensor and laser on.

14. Make sure that the laser will hit the sensor. 

15. Drill a hole at the bottom of Tank 2 and the top of Tank 3 to fit a HDJ.

16. Run a string through the HDJ.

17. Attach Tank 2 and Tank 3 together.

18. Put the rubber washer and cork through the string so that it will close Tank 2.

19. Drill a hole out the side of the top of Tank 2 so that the string can be attached to the servo

20. Tie the string onto the servo.

21. Get another Tank. We will call this Tank 4.

22. Drill a hole at the top of Tank 4 to fit the shape of the water pump.

23 Attach Tank 3 and Tank 4 together and Use the Marine Sealant to hold.

24. Drill a hole out of the side of Tank 4 so that a hose can run through it.

25. Drill a hole in Tank 1 at the top to fit a HDJ.

26. Insert HDJ into Tank 1.

27. Connect hose from the Water Pump in Tank 4 to the HDJ on Tank 1.

28. Make a base for the Water Distribution Model as you please. 

29. My group used wood and added a handle to the top of Tank 1

30. Use the Arduino and code to attach to necessary components.

31. Make sure to control the amount of water flow via the Water Pump by lower the amount of voltage received.

32. The laser will run off a “light on” and “light off” sequence.



1. Enter water into the side funnel on Tank 2.

2. Add Syrup to turn the clean water dirty through the side funnel.

3. The laser will be diffracted by the dirty water and the Arduino code will then read “light off”

4. “light off” will open up the gate via the servo connected to the string.

5. The water will then run into Tank 3.

6. The Pump will send it from Tank 3 up to Tank 1.

7. Tank 4 acts as an excess tank for any water the runs through the Water Pump.

8. The process repeats telling the gate to open and close when the water is dirty.








  • The project was a success. However the only major problem we ran into was getting the gates to close. I believe we needed more power in order to get the right amount of suction. If we were to expand this project we might try making a bigger scale model. 
  • There are different ways you could use this model, but the main idea is having water moving from Tank 1 to Tank 2 via a laser and light sensor. 
  • You could use this for a household water system and the laser knows when to switch out the tank. 
  • Another idea I had was to put different water colors into each tank. Then you would time synchronize the tanks to switch at the right time. This would cause a water show to continually move from tank to tank color by color. 
  • You could also use this as a juice machine. The laser would be able to tell when the water would be too frozen or to concentrated so it needs to switch, or turn on, and stir the tanks.
  • After building the project we’ve came to the conclusion that in order to be more precise and effective we should try and use different types of lasers such as green lasers. Each type of laser has its own strength, therefore its important to be as accurate as possible.
