Connected to the existing drinking fountain

UCI Students can now use the drinking fountain or enjoy chilled, purified water in a to-go container

In addition to the millions of gallons of water used in the process of making plastic bottles, on average, two gallons of water are wasted in the purification process for every gallon that goes into the bottles

Stormwater Runoff DesignStormwater Runoff DesignAlbany Village, UC BerkeleyAlbany Village, UC Berkeley

Wide landscaped areas receiving roof runoff

Plantings for swales: dogwood, flowering shrubs, native grasses and currants (also note covered enclosure for trash containers), rushes and maples, and ferns

Chain of detention ponds take runoff from parking and street near recently restored Codornices Creek

Large swale takes runoff from a perimeter parking lot edged by community gardens and a natural area. Rocks prevent erosion at curb cuts; raised drain prevents flooding.
