The Waterpod project based in New York city, consisting of a group of artist, decided to attempt to design, build, and have five people live on a self-sufficient, as possible, barge for a period of six months. Our Team, along with other teams from our Engineering 215 class at Cal Poly Humboldt, were given a list of problems that needed to be addressed. Some of these problems were food, clean water, electricity, and waste management. Each team was given a task, which they were to research, design, and build a system that completes the task given. Once completed, the projects were shipped to New York, where they were implemented on the Waterpod's barge~(Plan as of 5/5/09). The Waterpod team's barge is planned to set sail on June 1st, 2009 and to cruise the New York Waterways along the Hudson River docking at different places along the way. While docked, the public will be able to come aboard and see the different systems being used by the crew to survive.

Introduction[edit | edit source]

Our teams objective was to design a system that would grow food for the occupants of the barge without the presence of soil. There are many different types of soil-less grow system designs. In the beginning the client gave a specific set of criteria to our team. We used the criteria, to help us make a decision on what type of soil-less system we chose from. Our Criteria were:

  • Cost
  • Size
  • Weight
  • Durability
  • Transportability
  • Ease of set up
  • Use of recycled materials
  • Design and construction time
  • Educational value
  • Level of energy efficiency

The two soil-less system types we chose between were aeroponics and hydroponics. Each of these two types had many different designs that we could choose from. For aeroponics, there was the True Aeroponics, Deep Flow Aeroponics, Bubbleponics, and Fogponics. Right away we could eliminate the Fogponics system due to the high cost and our small budget of just 300 dollars. Hydroponics had many design choices to choose from as well. Some of these include, NTF (Nutrient Film Technique), Ebb and Flow, Wick System, and Drip Systems. The Nutrient Film Technique was able to be eliminated in the beginning because of the large amount of water that this system would require.

As the criteria became more specific, our choice of which type of systems we could choose from became easier. At first all that we knew is that we wanted to use as little electricity and water as possible, but had no figures on how much was allowed to us. This made most of the systems still available as choices. As a team we came up with many different alternative design solutions, then met up and weighed the designs against our criteria. By doing this our team was able to eliminate all but the top three designs that met our criteria best.

These three systems designs were Umbrella Aeroponics, True Aeroponics System, and the Bubbleponics Supertray. Our team made a few changes to the True Aeroponics System design and decided to build it. After we talked with the client a little bit more about their final criteria for us, we decided to change our design. The energy consumption for the pump required to run this system was more then the client was willing to use. Instead we decided to keep our overall design, but to make it into a gravity fed hydroponic system. Eliminating most of the electricity required for the growth of their plants.

Final Solution[edit | edit source]

Our final solution, "The Drip Hydroponic System" was designed to best fit the needs of our client.

Implementation and Use of Design[edit | edit source]

The hydroponic system should be set up in an area that has regular temperatures that hover between 55-70 degrees Fahrenheit. Nutrient solution will have to be bought and then mixed with the correct ratio of water to fill the fifty-five gallon drum. Once the pump has been fully submerged into the solution container it will sit on the bottom. Then place the desired plants in the sixteen holes on the 8" plant housing. Once the plants have been placed and pump has been plugged in with the timer, turn the pump on and watch the plants grow. The solution will have to be changed out, on average, every 7 days and a new solution batch mixed up for the plants. The solution may be need to be changed either more or less frequent due to different outside variables that can affect how fast the plants use the nutrient Solution. These variables include humidity, temperature, and size of plants. The only part of the project that needs to be watched is the nutrient solution drum. The Ph and Temperature inside of the drum should be checked regularly in order for the plants growth not to be stunted.

Results[edit | edit source]

The Drip Hydroponic System, after some alterations, works perfectly. During tests runs the system grew tomatoes, strawberries, and lettuces for a week. Growth was noticed and no leeks were discovered. All together the system is functional and meets the client criteria. The Drip Hydroponic System uses very little water, uses very low electricity, and is shippable.

Construction instructions[edit | edit source]

The Construction instructions for our Drip Hydroponic system are summarized with photos in the PDF on the bottom. On average the assembly time takes only one hour. The only tool that is needed is a jar of PVC cement to permanently join the different sections.

The hydroponic system should be set up in an area that has regular temperatures that hover between 55-70 degrees Fahrenheit. Nutrient solution will have to be bought and then mixed with the correct ratio of water to fill the fifty-five gallon drum. Once the pump has been fully submerged into the solution container it will sit on the bottom. Then place the desired plants in the sixteen holes on the 8" plant housing. Once the plants have been placed and pump has been plugged in with the timer, turn the pump on and watch the plants grow. The solution will have to be changed out, on average, every 7 days and a new solution batch mixed up for the plants. The solution may be need to be changed either more or less frequent due to different outside variables that can affect how fast the plants use the nutrient Solution. These variables include humidity, temperature, and size of plants. The only part of the project that needs to be watched is the nutrient solution drum. The Ph and Temperature inside of the drum should be checked regularly in order for the plants growth not to be stunted.

Next steps[edit | edit source]

We are closely monitoring the drip hydroponic system as it travels to New York and is then implemented in the barge. The team will be following the progress of the Waterpod throughout the six months to ensure of final design was sufficient for their use. We will also be asking the Waterpod for feedback on the design so that the team can iterate the design after testing has proceeded.

In addition it is necessary to find out:

  • Overall efficiency of the design.
  • Quality of the final developed product.
