it's treating all of the black water in the building so we can reuse that water to flush toilets and urinals in building we have been able to save 60% of our water -- which is equivalent to 1.5 million gallon thes of portable water we served each year with on-site water treatment systems we heard from a lot of other developers in san francisco they wanted to collect and treat water sources in 20 level the san francisco public utilities commission talked with the building inspection as as the san francisco. department of health we had a number of stakeholder outreach meetings for an ordinance that would allow for the collection and treatment of water treatment in buildings it was passed in

2012 for single individual build buildings in 2013 we wanted to expand for district scale systems how we define district scale systems is more than two buildings today you can install on-site water treatment system in an individual buildings or sharing and selling the water between buildings in the city. or ordinance this is just a quick overview of the ordinance in the ordinance i want to stress was a great partnership with the san francisco building inspection steve paneli and public health june win craft who is here today -- the city can come together and remove barriers and policies that previkt innovation from happening in san francisco. the role of the public utilities commission is program administration our job is to help developers architects and

engineers to understand what nonportable water they can reduce in the building what they can use that for we track we want to know what kinds of water savings are achieved through the buildings and incentives i will speak to in a minute. the role of the department of public health is critical they issue permits to operate these treatment systems why this is critical we want to make sure we're protecting public health we want to ensure these public water treatment systems are protecting health when they're used to flush toilets or irrigation purposes the role of irrigation department inspection is critical they help in term terms of installuation and approval of on-site water treatment systems quickly it streamlines the process and

consists of three major steps design construction and operation phase. the design phase is applying to the san francisco puc about what kind of water source you would like to collect how you propose to treat it and use it for getting into more details with an engineering report that is provided to the san francisco department of public health which requires approval to obtain your permit from the building in inspection -- cross connection being between portable and nonportable a test is performed again to ensure the pipelines are separate and operation are three phases the system is started up but the water is discharged to the sewer to allow the operator to get a sense of how the system is working and ultimately use the

water for nonportable application for nontoilet flushing or irrigation the san francisco public utilities commission provides technical and financial assistance we have developed the guide book to help the steps i walked through. we have a calculate cue later helps them understand should i collect drainage and gray water what kind of demand do i have in the building? currently with i have a grant program the san francisco puc will provide up to $250,000 for an individual buildings as long as they save a million gallons or more of portable water each year for ten years. we also have a $500,000 for district system that saves 3 million gallons up to ten years if in deed this legislation goes forward the puc disease not

provide grants for ordinance or requirements we're looking at amending our grand programming we're considering things if it's an existing dual puming building -- similar to what weiner mentioned a few minutes ago -- wants to connect to one of these new buildings that are forming a district scale water system project. we're aiming to keep the program available to projects that may not necessarily fall under the ordinance there are examples out there of projects that may not fall within the proposed legislation. we're also looking at our capacity fees as well as flow factor assessments and we have been looking at modifying their fees our plan is to take it back to our commission the san francisco public utilities commission with proposed change

in early september. i mentioned earlier we collect a lot of information and track these projects happening in san francisco we have a report -- all of the information is available online this report and i want to highlight a couple examples that are happening today in san francisco. st. anthonies has arraign far vesting system for toilet and urinal plushing bg and e is an existing building that retro fitted the building to collect water for toilet and urinal flushing pier 27 harvests water for irrigation -- in the city is collecting rainwater store and gray water for toilet and urinal

flushing as well as irrigation. transbay transit center one of the original proponents in collecting and treating alternative water sources for gray water systems for urinal and toilet flushing as well as irrigation 31 fre mont -- i think you will hear a presentation on this is you aren't construction to intall a system for collecting rainwater for toilet and irrigation. the last examples are examples of scale operations maconi is looking at expanding the center there say lot of drainage at masconi center we're looking to capture at the convention center as well as the possibility of

installing a truck fill station to provide water for street sweeping purposes in downtown san francisco. we have another project. project. puc has been working with the department of public works to install a treatment system at un plaza the truck fill station the purpose of the water would be again for street cleaning downtown san francisco irrigation and for fountain make up water as i mentioned all of the materials are available online the ordinance our guide book and grant pam at smp.org and i'm happy to answer any questions you may have >> thank you. your staff has been helpful with this process we appreciate that. a couple of questions pirs thank you for those examples i think

it's important for the private sector to see we're not just telling private owners what to do with the cities and transbay the governmental building are being build that is important i think the masconi center falls within the area as well i think everyone's going to have to comply with this legislation. so a couple of things. in terms of monitoring thank you for mentioning that i know the department of public helt is actually taking another look along with other cities about whether the health standards for monitoring gray water but also black water are too conservative can you comment on that >> certaintily in the state of california there are water quality standards for gray and rainwater today however there are not more black water storm

or drainage water. the department of public health established water quality standards although there will not monitoring requirements today however we believe as a city these kinds of systems should have ongoing monitoring so we developed or program also the san francisco puc is spearheading a national program to look at what is the appropriate water quality standard we have a project we're working with we're funded by the water water research foundation with a panel of experts to develop -- public officials come to consensus at the end of the calendar year looking at water quality standards and monitoring requirements >> great. i also i know the puc is

evaluating potential fee adjustments for buildings that have water reuse systems i want to thank the agency to do that and i want to encourage the agency to make the fee adjustments requiring this for these buildings we want to make sure also they're getting a benefit in terms of less strain on the sewer system. in addition to buildings that do it volume -- volcano tier -- voluntary -- particularly the

incentive funds to help buildings link together to form districts since we're not man dating districts here that is a still a powerful and importative innocent incentive of 3-4 buildings are sharing it spreads the costs and makes it easier for everyone. i hope the agency will considerly consider that. p you could comment we want the city ultimately to be providing recycled water to san franciscoians i know the west side plan is water recycling plant is moving forward. the east side plant for the cohen's district is a little bit further off. i want to get your take on what we can expect to see in the future. >> so we are supervisor weiner

mentioned san francisco looked at the east side and conducted use facilities about building a plant on the east side of san francisco for toilet flushing for buildings whereas the west side is for irrigation in the puc is coordinating with waste water enterprise who are activitily in the water sewer system plant. who are working to upgrade an old aging infrastructure the proposal for the water recycled treatment plant would be located in the south east treatment plant as you can imagine we need to keep the plant running while doing modification to sewer system space is limited so we're working closely with the sewer system program anticipating when we do move forward with construction it would probably be around 2026 there is a lot of moving parts with the south east

treatment plants the bio solids moving forward again space is limited we need to keep the plant running certainly the east side recycled water is part of the portfolio and consider that an important component within the water program. >> when will the west side facility be operational >> we're currently ending the requiremental review program we're planning to go to the commission in august of this year if all goes well with our approvals going into construction with in 2016 with completion in 2018 so a two year construction for the project >> for the benefit of the public i know the west side will provide irrigation to the golden gate park where will the water generally be used >> the west side recycled water project we're building a

treatment plant in ocean side with the existing waste water treatment plant we would serve golden gate lincoln park and portions of the pracidio >> again i would say i really think the city needs to move forward aggressively with it's own water recycling capacity i know it's not something that happens over night i don't think it relieves our need for buildings to have recycled water system even in the roads it's going to take a while i would encourage creative thinking how we might be able to start recycling water for example we're renovating our parks one by one i hate the fact that the deloris park is reportable water it should be recycled water if

ginsberg were here he would say we would love to do that but we don't have it -- move aggressively even if it's one step at a time addressing needs thank you. >> thank you. >> i have a couple of questions quickly i wanted to know the nonportable water program you spent time talking about the future you would like to go into for san pran what is the cost associated to get us to that level of using nonportable water consistently? >> the parts of our program recycled water water we're focused on nonportable for irrigation as well as on-site water treatment plans we have

six projects online in terms of water treatment systems in the building we have total 25 other applicants that are considering using nonportable water in a district in san francisco. the number is growing. just in terms of when we pass the ordinance in 2012 that enabled a streamline process to move forward with these kinds of decentralized water system we're focusing on nonpotable when it comes to san francisco. >> so there are no costs? >> sorry. i apologize. the costs are to the building owner so with treatment system may range from $250,000 to a million dollars it depends on the on-site water treatment system that is selected for example the in our building the living machine costs approximately $1 million in our

system you will hear from 181 fremont they will know in terms of how much that treatment system is. there are 15 vendors, we have collected throughout the country that provide treatment system it varies how much water is collected and used etc. unfortunately there is no one answer there say range >> does that the mean building owners are able to select their preferred treatment system? >> yes. that's a great question. thank you. what we ask for is an engineering report that looks into specifically what water are you going to collect gray or rainwater and how are you going to treat it? what treatment system are you going to reuse? a membrane bio reactor which is compacted versus water treatment

machine. all of that is specific very detailed that gets approved by the department of public health. we don't say what kind of treatment system you need to use. >> thank you very much. supervisor kim? >> thank you. it was great to have an understanding the work our new city public buildings are doing in whole and to learn a little bit more about this proposed ordinance. i think is definitely a step in the right direction i think there is nothing more tragic than the amount of clean water we waste that could have otherwise been gray water foundation drainage this is something good to see i noticed some of our publics buildings like pier 27 and a couple other sites you said their primary

nonpotable ratter is rainwater? >> yes so pier 27 was collecting rainwater they were also complying with the city storm water ordinance as a way of complying with that ordinance and installing harvesting system to reuse the water for those purposes and uses >> these would require these large development projects would reuse rainwater gray water and drainage is it all three or either/or >> it doesn't require any particular -- they have to do a water budget then try to meet as many of the water needs as possible. with those various sources >> one of the concerns i had about rainwater we haven't had a lot of rainwater. so in a year like this year i

imagine could of these sites would convert to potable water instead. >> we have designed our program to cover all types of water sources so it's not just rainwater in case it doesn't rain there is also the opportunity to look at other sources that are more reliable and readily available and produced on a more ongoing basis. >> i know this is beyond the scope of ordinance supervisor weiner talked about sites on the east and west side. on the west side for irrigation and east nonpotable water to developments if smaller buildings are interested in also converted to nonmore -- nonpotable what are the alternatives? >> for smaller use we encourage

rainwater services using arraign barrel to catch your rainwater we also have what the city of san francisco you can install a three way install irrigation that is not spray for homeowners we have a program online in terms of material we're actively seeking a contractor to encourage more workshops and more outreach with our residence to expand the program further we anticipate nah program being up and running again. in the fall of this year. >> i wasn't aware of that so single family own owners and smaller buildings go to pcu to rerout their water >> yup there is permit required from the department of building

inspection if a homeowner wants to alter al tear yor plumbing if they want the bath water for outdoor there is the irrigation permit that is required by the building inspection. san francisco will permit that water to facilitate that process >> so we're paying for that permit. >> yes and the puc will rebate the permit fee to the homeowners and a manual online to help them how to install gray water systems >> for those that may not be familiar are there any costs to doing that? are there any health concerns they should be thoughtful about when they convert housing to that type of system? >> that's why i have been stressing the word sub surface you are not treating the gray water what you are allowed to do

under the state of california is take the laundry and use it in your backyard for sub surface irrigation and spray you don't want to come into contact with that water for health concern. also you don't want to irrigation any register tables you would eat. with gray water but there is certainly applications again we have had a program in place we will continue to resume that place once we get get another contractors so there is cyst from san francisco residents we provide workshop and training >> routing that water to your toilet is there any potential kurns there? >> we handle that case by case basis i would defer that to june for the department of public health we want to ensure the public is protected pr any potential contaminates in the

water. >> it's a great opportunity i want to make sure everyone is well educated on the safety of installing a system like that in our home which we want to encourage our residences to do >> thank you. >> thank you. >> thank you. i think it's also important to understand when there are treatment systems where you are actually treating the gray water black water really it can be used for so many different purposes which i think is really exciting for the future of water thank you. now for our final report before public comment i ask bill worthan from urban fabric working on 181 fremont water reuse system. >> good afternoon my name is bill worthin i'm the founding

principle for urban fabric -- we work with the san francisco green building code i'm here to talk about 181 fremont those of you that know 181 it's connected to the transbay terminal it's a hard connection to the public park it's the lower 2/3 in the building up in the cut is commercial use and the residence is 637 luxury residences year-and-a-half ago when we looked at this project it's in the san francisco for the lead goal -- we were asked by jay paul and the architecture and orlandoidiaz and [inaudible] as well. we were asked what it would take

to get to lead platinum we need to luke at water reuse this building has an on-site. membrane bio reactor the tanks are installed i will show pictures of it in a minute the tank takes all of the water from the residential units as well as bike changing in the commercial office runs it through p five building the gray water systems and back up to the toilets in the building it will save 1 million gallons a year. we did a water budget we're the first project in the city's quarter of a million dollar grant to receive the system. what is here is the gold and platinum strategy with the gray water use what is it take to get to the use of platinum without game works changing the

architecture which is not going to happen so we had to look at on sign water resewers we were the water on 528 -- and back in 2007 and 2008. so the architect had experience with how the technology worked and figure out how to allocate the space go through a water budget and figure out how it would work out. these are the tanks sitting in the basement right now the first with the person in front of it that is the membrane bio reactor the building is using rainwater collection if this is a building under the storm water ordinance we would have to put in the tanks in the project any way. and there is tanks for the great water collection the pre treatment and the treatment before it goes back up into the building the reactor is we are

talking about two types of reactors that do the same thing -- or a living within this is an aqua fill bio membrane reactor the system is eight by 16 feet treated 5,000 gallons of water a day to compare that is the same size system in 525 golden gate puc headquarters if this is all office tower would ut the same system 5,000 gallons a day. this system costs $300,000 to install plus the rainwater catchment which is 120,000 plus the cost of the dualing plumbing on the waste side because we're in the purple pipe so the cost is on the purple supply side. these are the tanks if anybody

would like a tour we are happy to set that up. we have brought developers through it. i think the key important in my experience with water reuse is 95% of the water goes into a commercial office building and 50% of the residential nonpolar resources this is an opportunity for us to deal with water supply and keep the potable sources with nonpotable supplies that is an important point. if anybody wants to know more about how the water works urban fabric fabric.com blog i think the key points are the system practical i spent a week last june to kick the tires on the system they installs we
