PV WaterUsageBreakdown

In 2013, Portola Valley residential water consumption was 305 gallons/person/day, up from 283 in 2012. By way of comparison, the Bay Area average per capita was 79. Since 70% of Portola Valley residential water usage is outdoors there are many opportunities to cut consumption by 25% as mandated by Governor Jerry Brown. (In Portola Valley, we expect to actually need to cut consumption by 35% since we are in the heaviest consumption tier: more than 165 gallons/person/day.)
