SAN FRANCISCO (AP) - A San Francisco lawmaker wants to require new buildings to use non-drinking water for toilet flushing and hydrating plants.
The San Francisco Chronicle reports that legislation introduced Tuesday calls for many large new buildings to use gray water - wastewater from baths, sinks and other kitchen appliances - for toilet flushes and landscape watering.
The plan would require private developers to create piping systems to capture and clean the gray water. The Chronicle says the proposal has drawn criticism from some developers, who say it would add millions of dollars in construction costs when there are cheaper ways to save water.
The proposed law also calls for the city to use gray water to clean and irrigate public spaces within 5 years.
