DESIGN PROCESS

FIRST REJECTED IDEA:  The filter would attach to the faucet externally  

The Idea:  

The first idea we rejected was that the filter would attach to the faucet externally. We thought this would be a better idea for maintenance on the filter, and for possibly replacing the filter if needed.  

Rejection Reason 1 - Processing Water:

The idea could not have worked because the processes of filtration that we chose takes time. The amount of time the water takes to pass through the faucet is not nearly enough time to filter anything using the processes that we chose. So, you would be left with undrinkable water.  

Rejection Reason 2 - Energy:  

Electricity is needed for our filtration process because the mixing chambers require electricity. In such a small area the electricity would be hard to connect to the attachment, and there would be multiple visible wires.  

Rejection Reason 3 - Efficiency and Consistency:

An attachable filter would be less efficient, as it would need to have replacement filters and maintenance most likely. An attachable filter would also not be as effective because of the amount of time in the filter. It would cause problems in the consistency of water cleanliness.  

Rejection Reason 4 - Attachment:  

With an attachable filter, depending on the pressure the filter might not be able to stay attached, making it likely the filter would become unstable.

SECOND REJECTED IDEA: We would have one large underground filter per house  

The Idea:

The second idea we rejected was that each house would have one filter, rather than having a filter for a larger area. We thought that it would be better for the filtration in each house, and for the consistency.

Rejection Reason 1 – Unoriginal:    

Our second idea was very similar to the average process of filtering wastewater. With a similar power source and overall idea. This realization led us to have the idea of having an off the grid water filtration system for people who live in rural places that do not have access to clean water or electricity.  

Rejection Reason 2 – Not Helpful:   

We realized this because of how uncommon it actually is for dangerous metals in pipes to get into your water, which contradicts the “problem” we were trying to solve.

Rejection Reason 3 – Too Expensive:  

This is because our idea was to have every house to have their own coagulation system. Having another layer of filtration would be helpful, but the cost of this is far too unrealistic because the ratio to people getting sick that have electricity is far lower than people who do not have access to electricity. 7 out of 10 people who don’t have access to clean water live in a rural area. This is what led us to having a cheaper, off the grid, fully filtering, disinfecting, and coagulating system.
