A recirculating fountain and limestone-edged bioswale in the resident habitat at a supportive senior community.
Project · Pro Bono with HFCC

Water that cleans itself.

Three fountains reclaim the water, clean it with biochar and lime, and return it — the whole loop run by a single 100-watt off-grid solar system. No meter. No grid. No bill.

§ I · The Brief

Living water, where seniors live.

Permanent supportive housing for seniors who reached homelessness late in life. The brief was restorative, not ornamental — bring moving water into the ground where people live. One hard limit: no utility bill, no grid tie.

That single constraint wrote the rest of the design for us. If the water had to be free to run, it had to be a closed loop — reclaimed, cleaned, and returned on site, running on what the sun hands over and not one watt borrowed from anyone.

§ II · The Build

Three fountains. One closed loop.

Three fountains reclaim the water, clean it with biochar and lime, and send it back out — linked by aqueducts so the water keeps its appointments instead of standing around going stagnant, which is the one thing water reliably does the moment you stop watching it. A limestone-edged bioswale takes the overflow and anchors a band of native habitat at exactly the height of someone who would like to sit down.

The whole apparatus — all three fountains and the filtration — runs on a single 100-watt off-grid solar setup. No grid tie, no meter, no monthly envelope from the utility. The sun runs the water, the water cleans itself, and the loop closes, having asked the larger economy for precisely nothing.

The sun runs the water. The water cleans itself. Nothing leaves the loop.
