The Water Commons, located near the eastern end of the Living Village’s east-west axis, is intended to bring the village community together around water and highlight its influence on peoples’ lives. The Water Commons filters rainwater and wastewater through a series of constructed wetlands and rain gardens that step down the hillside, thereby allowing gravity to move water through the system.
Rainwater Capture
Rainwater from the roof is captured and stored in two 10,000 gallon cisterns, buried below grade is treated then reused for spray irrigation and resident laundry.
Waste Water Reuse: System Details
Wastewater from the building flows by gravity to primary treatment tanks then passes through trickling filters for further removal of organic matter and conversion of ammonia. After clarification, the water moves through a vertical flow constructed wetland for additional treatment, then is filtered, disinfected, and stored for reuse in toilet flushing and drip irrigation. Any surplus treated water is discharged to the sanitary sewer, with controls and odor treatment managed in the water treatment room.
Storm Water Management: System Details
Stormwater is treated and managed on‐site through rainwater harvesting for re‐use, surface stormwater features, porous pavement in the vehicular areas with subsurface storage, subsurface infiltration systems below walkways, and imported highly permeable landscape soils.
