the jordan group, and ms. collins. all of you. we thank you for doing such an outstanding job, and let me say this, that every year they are accepting volunteers, so any of you looking for something to get involved in, there are a lot of good things to do. this is one of the many that you can get involved with and support. now, let me give you the very important direction -- there is food over on the other side. please help yourself. hang out with us a little while longer. god bless you. go in peace. thank you.

because we have a great waste water system here in san francisco, we do about 80 million gallons of waste water here in san francisco, which means we basically fill up 120 olympic sized swimming pools each and every day here in the city. we protect public health and safety and environment because we are discharging into the bay and into the ocean. this is essentially the first treatment here at our waste water treatment facility. what we do is slow down the water so that things either settle to the bottom or float to the top. you see we have a nice

selection of things floating around there, things from bubble gum wrappers, toilet paper, whatever you dump down the toilet, whatever gets into our storm drains, that's what gets into our waste water treatment and we have to clean. >> see these chains here, this keeps scum from building up. >> on this end in the liquid end basically we're just trying to produce a good water product that doesn't negatively impact the receiving water so that we have recreation and no bad impact on fish and aquatic life. solids is what's happening. . >> by sludge, what exactly do you mean? is that the actual technical term? . >> it's a technical term and it's used in a lot of different ways, but this is organic

sewage sludge. basically what it is is, oh, maybe things that come out of your garbage disposal, things that are fecal in nature. it's sludge left in the water after the primary treatment, then we blend those two over and send them over to digestion. this building is built to replace tanks here that were so odoriferous they would curl your hair. we built this as an interim process. >> is there a coagulant introduced somewhere in the middle of this? . >> this coagulant brings solids together and lets the water run through. that gives us more time in the digestion process, more time to reduce the amount of solids.

these are the biggest ones in the world, like we always like to do in san francisco. they are 4 meter, there's none like it in the world. >> really? wow. >> three meters, usually. we got the biggest, if not the best. so here we are. look at that baby hum. river of sludge. >> one of the things is we use bacteria that's common in our own guts to create this reduction. it's like an extra digestion. one of the things we have to do to facilitate that is heat that sludge up and keep it at the temperature our body likes, 98.6 degrees. >> so what we have here is the heat exchanger for digester no. 6. these clog up with debris and we're coming in to -- next wet weather season so we always come through here, clean them out, make sure that we get maximum heat exchange during

the colder wet weather. sludge season. >> rubber glove. >> right here. >> rubber glove, excellent. all right, guys. >> thank you. >> good luck. >> this is the full on hazmat. . >> residual liquid. we're taking it time to let it drain. we don't want to get sludge on it necessarily. take your time. stand on the side of it. . >> should we let it release for a while? . >> let it release. >> is that the technical term? . >> this is the most important bolt on the whole thing. this is the locking bolt. it locks this thing right in

place. so now. >> take your hammer and what we want to do, we get rag build up right in here. the hot water recirculates right in here, the sludge recirculates in here. the sludge sometimes has rags in it. all we want to do is go around the clean the rags. let me show you how. take the slide hammer, go all the way through the back, go around. >> got you. >> during the real rainy season, how does that change the way dealing with this job? is it a lot more stuff in there? . >> what we do, charles, we do this quarterly. every four months we go around and clean all the heat exchangers so we don't have a large build up. . >> go around?

. >> yeah. (sound of hammering). >> what i'm trying to do, charles, is always pull it out on the low stroke. >> right. so you are not, like, flying out. now talk about clean up. . >> then where does this stuff get deposited? . >> we're going to dump it in a debris box and it will go back to the plant. >> if you think back, the romans came up with a system of plumbing that allowed us it use water to transport waste away

from the hub of civilization, which enabled cities to grow. . >> you have a large bowl, a drive motor and another motor with a planetary gearbox with differential pressure inside there. the large mass up there spinning separating the solids from the liquid. we have to prevent about once a month, we go in there grease those, change the oil, check the vibration levels. the operators can tell just by the hum of that machine that it's a harmonic noise emitted that it's out of balance and the machine needs to be cleaned. it will start vibrating and we have vibration analysis machines that will come over here and check the levels. so it's kind of an on-going

thing that you have to stay on top of on a daily basis. >> handled properly, you take organic residuals, as we call them, that are leftovers of our society and turn them back into some energy. and we have another ability to take that sludge and get a nutrient value for crops there. we actually are running a kind of composting energy recovery system. >> well, this is a dirty job. we try to do it safely and we try to do it without imposing too much on the public. people want to flush their toilets and have things go away and not be bothersome again. we do a lot to try to accomplish that. i'd like to invite you to come back any time you want. once you got this in your blood, you are not going to be able to stay away. the raging waters are fun and when we do digester cleaning i

really hope you can come back. that's quite a sight. >> yeah, that sounds interesting. >> i really appreciate you coming by and it was a >> the mayor, the office of workforce development, kick off a new program which is to engage some of the artists in reinvigorating the streetscapes. organized in partnership with neighborhood based economic development organizations, the art in storefronts taps into the incredible creativity of the artist community to help improve

the quality of life and the business climate in poor neighborhoods. the tenderloin, central market, they view, and the mission's 24 st.. at the launch party, the mayor released the first of 13 projects located on taylor and market street. we were there to capture the celebration and to get a closer look at the newly transformed storefront. >> we have an analyst at saying, you know what, we get it. if we close out and we put some plywood, we know it will have graffiti on it. we know that people will not respect this space. they are opening up their businesses, their buildings and they are saying, let's invite young artists in and let's have these artists go at it in great very visually stunning storefronts. >> this is a pilot project that

was started by the mayor as part of his local stimulus plan in partnership with the mayor's office of economic and work- force development. we carried this space in the mission. we were hired to curate this project. we have been the ones that have been handling all of the day to day working with the artists helping to secure their locations. >> we are doing projects in central market, the tenderloin, the bayview, and the 24th street corridor. >> we are looking at the history of the neighborhood and their ability to translate a the kind of things that go on on a day- to-day basis. >> we have over 200 applicants. it was wonderful to see how many people participated. these people clearly understand

the neighborhood. >> this is a very unique neighborhood. it has always been involved in the arts from early on. of they have seen a lot of the art and what it has done to the neighborhoods. i think that they will still connected to it. they will actually embrace it. i think it will be a good thing for all of us. >> if you are walking in the tenderloin, you'll be able to see this piece that is in front of the original [inaudible] which is a restaurant that has a lot of history. there are exciting projects on market streets. there are two gorgeous minerals as well as six different installations. they are making huge figures that they will be able to see.

>> there is a definite level of appropriateness of stuff i am using. a lot of businesses died in 2009. >> i think i'm trying to deal with the maximum out of space possible. that is surging right now. everyone is doing what they can with what they have. sometimes that introduces a lot of interesting things. there is nothing that inspires quite like this. >> the project benefits both the property owner, the neighborhood, and the artists, all of whom have been effected by the economic downturn. >> this is brand new work. >> we chose artists that had a diverse array of media from home

video to coulter, paintings. >> when people walk around these neighborhoods, they will be able to see works that deal with the history of the neighborhood. they will see works that deal with movement and the works that celebrate some locations. they will be able to see works of that deal with new projects like the san francisco film museum which is a small organization that is starting. this is their first presentation to the public. >> this has introduced us to different organizations. they are building our portfolio. our project centers on a film that was found in 1906. shortly afterwards, the earthquake destroyed the majority of the market street

area. that is what we want to focus on. this is dedicated to film and san francisco history. >> we are having a support network now, this enhances our mission and what we are trying to do it and it will protect us forward. >> i hope that we continue. there are storefronts all over the city. we have been approached by many of them. it is about getting the resources together. >> this calley is working with the san francisco arts commission and building a tool kit. >> this will be an open source body of information. people can download the different things that we had to do with the artists. negotiations with the property owners. there is also the artist selection.

people can take it in their own hands to put art in the storefront.

>> the san francisco arts commission's public arts program

made a big splash in the civic center with the world premiere of three heads, six arms. the artist came from shanghai to help us celebrate the unavailing. we had a chance to speak with him about his work. >> the san francisco arts commission is pleased to be celebrating their relationship between san high and san francisco. the shanghai and san francisco. this is a 30 relationship that stretches back to win dianne feinstein was the mayor of san francisco.

we premiered a new work of art here in san francisco called the three heads, six arms. welcome to san francisco. thank you for bringing your extraordinary sculpture. can you tell me about what inspired you to create this sculpture? >> this started with some trips that i took years ago. i went to to bed and i saw a lot of statues and i started to really feel the spiritual life of people in tibet. it really inspires me and i went back to shanghai and i started the creation of this.

>> we see that one of the heads of the bullet it is your face. can you talk about the significance of that? -- we see that one of the heads of the buddha is your face. >> i started doing public art almost 10 years ago. what i want to express this as an extension of my our practice. this is an accumulation of my own experience as a performance artist. >> we see that the scale is very important. we have seen other works where a limb of this culture is on the fl
