crews. this allowed us to make this happen. they were blocking deliveries to the system, there is a little picture here. we have moved to the pump around with a wheat field test, we are still monitoring the situation, we are going to get out there and do more detections in the next week to verify that we have gotten yet. we addressed in the big leagues of was coming up on the street. we received a three-quarters of an inch of rain in that area and less than an hour. combined with high tide, we had hollowed-lying areas here. it affects up to 20 businesses

more or less. what you see here, the picture that was on the news that came from -- i am almost done, so ask questions. the last picture, let me show you a picture of this thing. we intend to be able to address these issues. thank you. >> if you recall, we started a project to work around that general area. and we ran into a pg&e utility box that wasn't where it was supposed to be. we had to cancel and start again. if we had been able to fix that,

this would not have been anywhere near as important. the since this is the only way to get the flow from the northern part of the city down from the southeast, having it leak is obviously unacceptable. if we had to build and repair it from the outside, it would have meant that we would be closing down two lanes of the embarcadero for many evenings over the next several months. it is great that it was able to be fixed from the inside. when we get that new main in place, we won't have to rely on this as the only way to get sewage from that part of the city. >> when we have an issue with this, we have about a day of storage and before we start the coh -- >> what is the level of service standard that we have adopted?

>> again, this issue will be handled -- >> 1.3 inches over three hours, it is very low. we are glad to throw everything we can at ait, we're looking at how the flow patterns are working in this will be a challenging area. we probably shouldn't have been developed a way it is. the community hall, and particularly the urban watershed assessment will be looking at what we can do to try to mitigate this. >> there was flooding the number of years ago.

you just can't fix it there. if you look at the watershed view of the world, you can see how you could avoid a runoff coming down. the other problem is that it was high tide. part of the discussion for ssip is if we're supposed to start pumping out the sewers to allow the water to a slowdown. this is putting infrastructure, these houses and businesses in a creek bed. >> we will see more and more of these with the sea level issues. the service goals that we established at the beginning as we learn more about that, it does not fully describe what we need to do.

>> that is the current system, so you may want to change them. the problem is that to change them may require huge changed all the collection points in the entire city. >> i thought that we have revisited those. >> we used to talk about them as five-year storms and nobody knew what that meant. we tried to figure out what it means for normal people in terms of how much water is falling from the sky. a recollection is that it is what it is currently designed to do. >> it is designed to hold a certain amount of water. it is experiencing some runoff, the lower-lying areas get

impacted. we will be bringing to you in the summer, the idea about what a double of the improvements we need to build and where they are impacted. >> that was basically to improve system performance concurrent design levels? >> correct. >> they did not improve the design standard? >> not yet. >> hire appreciate the images of the workers that are addressing the emergency conditions. i want to know if you would just give a brief description specifically related to the diver. what kind of employee that is, what kind of training they have? just to give an illustration of what they are doing, and how

they are resolving the problems and those emergency situations? >> we brought in a contractor, highly trained with various backgrounds and specialized in this field. >> will have divers in the water department that are not certified to do this kind of work. it was a 36-inch main. if you go in with an oxygen packs on, you end up having to drag 1,500 feet of oxygen. we brought in seven outside people to do it. >> can delete area, we have drained the line, but there is hot selling in areas, so they were not swimming through a fully charged force main. >> like shawshank redemption.

[laughter] >> there you go. >> thank you. and they were probably still available on youtube. >> world's dirtiest jobs/ ? they did a program on the waste water folks. >> is really quite remarkable. >> the other item as an update on the water system improvement program. >> i wanted to start with a brief update on awards. we have received a number of them at the latest one we got is the exceptional performance and safety award for the american public workforce association. we have logged over 3,200,000

construction hours without any major safety incidents. and all hours if the incidence rates are well below national averages. also, note worthy, last week received bids on our seismic home appliance 3 and 4, very important and critical projects. we did not expect that many, the contract with 51 million. it came in at 38% below. a pretty aggressive bid, a pretty well-known contractor. we have yet to certify that bid. a lot of the efforts on the

construction side have been spent on negotiating the backlog of change orders. we are about to finish negotiating all remaining changeover's on the number of projects, so i expect there to be something before you to close out a number of projects. i wanted to mention a couple great settlements that we reached on the east today segment of the bay division tie line #5. we reached a settlement for remaining change orders that will allow us to close the project 5 million under the total you have approved. that is good news. last friday, we also reached a global settlement on the number of change orders for the treatment plant. he carried a $9.8 million backlog and we were able to negotiate all those for $3.7

million under. but we were able to reach of verbal settlement that has yet to be put in writing. we were pleased with that, a lot of large changes at that plant. on the peninsula segment, we have been trying to work through a dispute related to some quality work on welding. we haven't been successful in those negotiations, so to avoid a costly legal action, both parties have agreed to pursue mediation on that. we will be seeking be assistant mediator and we will be doing that sometime in june. work is proceeding pretty much as planned, we are seeing some challenges. there were landslide incidents in recent weeks. it sounds big, but they are not

huge. nonetheless, it is impacting some disposal sites. there is also on forseen site conditions at the intake chaff that will require some changes and modifications in our work. there is no question it is carrying the largest risk. the total risk level is $50 million. we are now 50% excavated, the segment between the shaft and the portal, we are holding true through that segment. we are expecting that to happen in june. we are expecting to encounter some pretty challenging ground conditions in that area.

stay tuned to what we call squeezing ground. we're hoping to be able to delay it. we are trying to maintain safe working conditions. the show covers, we are monitoring the conditions there. what hundred and 75 feet a day, how wanted to brief you. our team is working very closely ha trying to come up with a recovery schedule.

the currently projected delays, i will be meeting with in the executive to make sure that the issue is high on their radar screen. very briefly, i wanted to let you know that we have changed over the management of the construction management bureau. it is now being replaced and is now moving on, replaced with one of our most capable persons on board that has been with us since 1992. i am very pleased with all the work we have accomplished so far together. i wanted to remind you that may 7 is the water for people event and you are all invited to join us.

>> mr. jensen? >> members of the commission, a few items to report. i spoke to you on a long-term viable water supply strategy. we will continue to initiate that in the coming months. in the previous meeting, we would want some capital debt.

the rate projections were part of the discussion of the two of ago. just so you know, we're operating on that. the key to the staff for making that available. wholesale water rates are on the agenda for the afternoon. we have some comments after that.

and finally, looking for the water system improvement program. we are in the process of producing the mid-program. for the board members, she is in charge of that. if there are any issues that you can find that we think need attention, we will present them to the commission with recommendations in the past. we value the close working relationship, the fact that the program is working incredibly well. i don't expect very bad news. there will be some constructive recommendations. any questions?

>> madam secretary, if you would call the consent agenda. >> approved a modification for waste water enterprise contract, north shore improvements. with the time extension of 150 consecutive calendar days and no change the contract amounts. authorizing the general manager to extend the term of between the san francisco public utility commission and the sanitation district, no additional funds are needed. the award water enterprise contracts for the peninsula in 2011 compensation. in the amount of 5 million -- to

the lowest qualified bidder. approve the plans and specifications and waste water enterprise contract. in the amount of $2,944,425, of which $1,862,164 -- funded by the department of public works to the lowest qualified and responsive better. for waste water enterprise contractors, mixed liquor, and headworks facilities improvement and improve the modification number to increase the contract with a time extension of 270

consecutive calendar days and authorize final payment to the contractor. wd-2627, reservoir rehabilitation and authorize the general manager to authorize the contract for the rehabilitation and seismic upgrade. approve water conservation operating agreement. with the urban storage for another two years, authorize the general manager to increase the agreement by $24,500 with a time extension of two years. accept work performed by 2595, sacrificial -- to descreasecreae

contract amount. and authorizing final payment to the contractor. >> any items to be removed from the consent calendar? can i have an motion? >> moved and seconded. >> the consent calendar passes. >> item 10, authorizing the general manager to exit an mla to not exceed -- with the duration of three years to fund the purchase and installation of 36 water conserving drinking fountains.

>> that was my cue for the power point. thank you. we launched an initiative where we installed 15 stations in public locations. for the purpose of clarity, where you can fill a water bottle. in 2011, there was a state and federal legislation to have

schools provide access to fresh drinking water. for many people, they assume there is access to drinking water, and that is not the case. at the federal level, it did not provide the school with an opportunity to opt out because of financial reasons. the initial initiative and other educational efforts, it seems like a the opportunity for us to secure a partnership with them. we will have the opportunity to get a sense of the time and cost for the installation and get some intel and insight. we heard from the plumbers,

initial units installed, what they found when they opened up the wall and have the pace of being able to install the units. with also set in california endowment, a statewide health foundation. they paid for all of the water bottles as part of the initial -- it is important to mention the role that the health department has played through out the process. we are doing pre and post tests to see if the children drink more water after the units come in, and we do see that frequently. the larger initiative program,

it allows you to install 36 of the public schools over the next three years. if they were chosen based on several criteria, there is no existing drinking fountain adjacent to the cafeteria or that it is there, doesn't work. the third criteria was the it was part of the upcoming bond. another 26 schools in addition to the 36 we are focused on will be covered vase of the upcoming bond work. educating the students over other beverages, to increase their awareness about where the water comes from.

an important component to this initiative, there is a mentor should program around the installation of the unit. for the shuttle component, high- school students are taking a the technical class's through this program, they will be able to shout of the installation. -- shadow the installation. this slide shows you a map of where the drink schools are located. and the next slide has a list of all the schools, the highlighted one's heart of the schools better on the superintendent's special zone lest the our priority zones -- list that are priority zones.

[chime] sure thing. let's see. the powerpoint presentation is gone. thank you. this slide shows the example of the budget for this project. the water enterprises supporting this effort through the conservation budget. it is fairly straightforward, we cover the cost to partner with the water bottles. for each of the line items in the budget, whether it is around the cost for the taxation -- tap station, what it could cost, etc.. the staff are extremely excited about the ability to continue to

partner with the department of public health a round of forging the federal government which regards to the kids that have access to drinking water on the premises. to thank the staff that has done the heavy lifting in making this collaboration happen, you can imagine is a lot of work. from the communications team, they provided a lot of leadership on this topic. they came up with the idea of having the shuttle component. and we have been working really closely from the school district. that is the presentation, and if there are any questions, we are available for that. >> for the school's not on the

list, what was the criteria for keeping schools off of the list? >> there are schools that we already covered that are part of the first pilot, and there are an additional 26 schools being covered through the upcoming bond, and there were schools that have water access with the drinking fountain that was adjacent to the cafeteria. >> the goal is to cover elementary and secondary schools? what is the timetable for that? >> three years. >> 2015? >> yes. >> what was the priority? >> we have been working with the school district trying to get a sense for them, when they will be doing construction or other work at the schools, the is trying to get into the summer months or the break months and getting in the schools that they h
