Feedback
Water tank cannot be placed above sink. Too high to reach the hose
Unstable
Too heavy to lift it up high
Have to use hands
Algae is a problem
The water stays inside of a bucket for a while and starts growing Green Algae
Factors that affect algae growth
Possible solution for algae
Flag to indicate water level Flag
Floating device
Semantic opportunities
Terracotta planter
Matryoshka dolls
Pallets
Housing
The real problem is keeping the tank filled. Housing makes adding water more difficult.
An indicator for water level could be useful.
Sourcing Materials

First Installation
First Functional Pump
Plastic Trash Can
Wooden Foot Pump
Feedback and Results Good Perfect water volume. Comfortable to pump. Operation discouraged wasting water.
Feedback and Results Bad Useless and confusing faucets. Cold tap had to be left open. Weak water pressure.
Changes to the site Compost bin was added. Plants were displayed around the composting toilet. Trash can was difficult to access!
Design Flaws Wood did not hold up well. Pump was not secure enough and began to leak water.
Water Tank / Planter
Planter Match the appearance of the water tank with Greens Grow’s style.
Problems Have to make our own lid
Unstable inner sleeve Install a ledge to put the lid on
Risk of leaking water
Back to DIY
External sleeve for flag
External sleeve for flag A sleeve added on to the lid would hold the flag up. No need to drill holes in the bucket.
External structure for flag A pulley system where the flag relies on an external structure. This requires more materials and construction.
