PPlanter is a scalable, reconfigurable public urinal and sink that uses modular biofilters to treat urine and wastewater. A network of sensors for automated monitoring and a web/mobile interface enable public feedback and participation in the PPlanter design and propagation of future iterations.
The PPlanter works for both men and women, and conveniently takes up a single parking space so that the entrance is flush with the sidewalk.
The PPlanter system works as follows:
- An ADA-compliant sink is supplied with a human powered foot or hand pump connected to a freshwater supply tank. The greywater from the sink, along with soap residue, flushes and cleans the urinal, keeping odor to a minimum.
- The greywater, soap and urine (blackwater) from the ADA-compliant urinal are funneled to a sealed storage tank. The combined water is then pumped into an adjacent planter that houses bamboo plants set in a lightweight mixture of soil and recycled styrofoam coated in pectin. The water from the urinal and sink is evapotranspired by the bamboo and released into the air as distilled, purified water. The bamboo harnesses the incredible amount of nitrogen and phosphorus found in the urine and uses it to produce more bamboo. With high traffic urinals additional planters can be added to the system.
Come to our fundraiser "Refreshed + Relieved" at 111 Minna Gallery on October 8th from 6-9 pm! Then, come see the first PPlanter prototype on October 20th at 5th St and Minna, anytime from 12 - 10 pm!
PPlanter is a rapidly deployable, reconfigurable public urinal and sink that uses modular biofilters to treat urine and wastewater. The network of sensors for automated monitoring and this web site are an integral part for public feedback and participation in the design of future iterations.
