EVERY DROP COUNTS 10% Voluntary Water Reduction in Effect JANUARY/FEBRUARY 2015 Whales and Sharks in the Sunol Valley?! Construction crews at the Calaveras Dam Replacement Project have uncovered a buried treasure, of sorts—more than 600 fossil specimens that date back to when the area was an ocean floor more than 20 million years ago. Alongside the scallops and clams, crews have found teeth from a megalodon shark (a giant ancestor of the modern great white) and, most importantly for science, 10 whale skulls. The fossil record from this period is limited, and these abundant and diverse finds provide new insight into the ancient environment of 20 million years ago. We will work to preserve these fossils to make them available to scientific research. A paleontologist covers a whale skull in Plaster of Paris to stabilize it for transport. Scallop Megaladon shark tooth Ringing in the New Year with solar Recent heavy rains still not enough San Francisco’s newest municipal solar arrays, installed atop City Hall and Thurgood Marshall High School, bring the total number of solar systems generating electricity for City facilities to 19. City Hall’s 80kW rooftop system and the 87kW system at Thurgood Marshall will generate more than 248,000 kilowatt-hours of electricity—enough to power 64 homes for one year. Both arrays are expected to be online and producing clean electricity by January 2015. While we welcome the recent wet weather, California remains in a drought and we need a healthy Sierra snowpack—our “largest reservoir”—to replenish water supplies. Until then, we ask customers to keep up efforts to save water. Our energy portfolio comprises 100% greenhouse gasfree Hetch Hetchy hydroelectricity, renewable solar and renewable biogas power—one of the cleanest energy mixtures in the country. We’re also the clean energy utility for the City’s municipal facilities and residential and business customers at Hunters Point Shipyard. Outdoor water use restrictions remain in effect. Don’t water when it’s raining, avoid irrigation overspray and run off, and limit sidewalk and hardscape washing. Also consider replacing old waterwasting showerheads, toilets, and clothes washers and fixing leaks.

Latest annual reports now available Our 2013-14 annual report, with updates on our water and wastewater system upgrades, advances in green power initiatives, and more is now available at sfwater.org/PAFR. Sewe Our “city under the City” Sewer pipeline replacement doubles Since 2010, the SFPUC Wastewater Enterprise has doubled the total miles of aging sewer pipeline replaced from 6 miles per year to almost 13 miles this past year. “Since we have implemented our new sewer assessment program, we have been able to pinpoint problem areas quicker and prioritize sewer replacement more readily,” says Lewis Harrison, Sewer Collections System Division Manager. We have also more than doubled the miles of sewer pipeline cleaned from 75 miles in 2010 to 170 miles this past fiscal year. Reusing that precious rain Rainwater harvesting— collecting the runoff from roofs or other hard surfaces for reuse— can reduce potable water consumption and help you keep your garden green during dry times. It also maintains the health and beauty of the City’s urban watersheds by keeping relatively clean water out of our combined sewer system. Lower flows reduce the energy and chemicals we routinely have to use in stormwater treatment— and also the potential for overflows and flooding. For more information, visit sfwater.org/rainwater. Construction kicks off for WSIP’s last pipeline project The Peninsula Pipeline Seismic Upgrade project, upgrading three Hetch Hetchy regional water delivery pipelines in four different Peninsula cities, is now in construction. The last pipeline project of our comprehensive Water System Improvement Program (WSIP), it will ensure that these critical water delivery links continue providing water to our customers even after a major earthquake. Completion is slated for December 2015. Brick-lined sewers still make up about 25 miles of our historic 1000-mile system. Free compost, classes, and more at garden supply pop-ups Approximately 30 Bayview Hunters Point community members showed up for the first Bayview Garden Supply Pop-up. Residents young and old came to pick-up free municipal “greenwaste” compost and mulch, take classes in soil health, waterwise gardening, and taste Spilanthes acmella—also known as paracress or the “toothache plant” because it numbs the tongue and mouth. Neighborhood youth get hands-on instruction. Next pop-up: Saturday, Jan. 17 Quesada Gardens, 3rd & Quesada 10 a.m. – 2 p.m. Public tours of 525 Golden Gate January 14, March 11 Reserve your place for an upcoming free bimonthly tour of our new green headquarters at sfwater.org/explore.
