REGULAR MEETING NOVEMBER 25, 2013 <br /> idea briefly on what the sewer overflow looks like (referring to the Power Point) the image to the <br /> left is under normal dry weather conditions the pipes are big enough to handle the overflow that <br /> comes through them and those all go to the treatment plant, the water get treated, and then <br /> discharged to the river in a clean state according to our NPDES Permit that we have. In wet <br /> weather however, we get a rain event, this is the 60 to 70 times a year that this happens, the <br /> sewer surcharges, so it can't handle all the flow, it backs up, and then spills over a dam and flows <br /> into the river. The reason that we don't dam that up entirely because if it didn't overflow in the <br /> river it would all overflow into people's basements, streets and other places that we would have <br /> serious human health issues. So here is our system (referring to the Power Point) the red dots are <br /> the 36 combined sewer overflows in the City. City limits is 40 square miles and half of our city <br /> limits is still on a combined sewer system. The development of this plan goes back to 1989, <br /> South Bend started study their CSO system as far back as then and really started in earnest <br /> looking at their long term control plan in 2002. They were working with EPA and DOJ came in <br /> and put a lot of pressure on actually everyone in the State to get these long term control plans <br /> done and developed. In 2008, they started their technical plan and were negotiating level of <br /> control with EPA and the Department of Justice and then in 2011, the end of 2011 signed the <br /> consent decree on the long term control plan. So here is what our plan looks like (referring to the <br /> Power Point) comparison to other plans about $40,000 on a cost per acre basis and we have <br /> talked about this before but our population is small and we have such a large combined area our <br /> cost per capita is very high, it's an issue that we're unfortunate to have, but nevertheless we need <br /> to take responsibility for and address. So our plan basically requires us to develop and eliminate <br /> these wet weather overflows at all times except for 4 times during a typical year. We can never <br /> have dry weather overflows and when we do have wet weather overflows we've got to disinfect. <br /> So we have to have some means of disinfection on the nine remaining overflow points that we <br /> have during those four occurrences a year. So it will be significantly less than what we have <br /> today. Some ask why not just eliminate them all, that was part of the alternative analysis that <br /> they looked at and they looked at a number of different plans to try to get the cost down and do a <br /> cost benefit analysis and to eliminate them all was I believe over a billion dollar issue and you <br /> would have half of the city torn up just separating sewers or building huge tanks to store it. We <br /> have talked about this as well we have do have some re-openers built into the plan. This is <br /> something that we are serious about it reopening the plan, it is very difficult to have a 20 year <br /> plan and not to expect there to be changes in it. So we know that there are going to be things that <br /> we can do with green infrastructure and with technology that we can make improvements on the <br /> plan and so we will continue to re-look at the plan and find better ways to implement this and <br /> hopefully save some money in the process. So the next five years here's what we are looking at <br /> in terms of requirements in our consent decree,by December 31, 2017 we need to have <br /> completed all the Phase I Collection System Controls. So the Phase I stuff that we have been <br /> talking about in separating sewers and trying to keep sewage out of basements according to the <br /> consent decree needs to be done by December 31, 2017, these are all controls,projects that we <br /> not only have in process but completed. Phase II controls upstream of the East Race we have got <br /> to start by March 1, 2014 and Phase II storage tank at Leeper Park we have to have started by <br /> March 1, 2017. So in the next number of years those are the key spots in the consent decree that <br /> we have to meet otherwise we will have stipulated penalties associated not meeting those. So <br /> here is our plan (referring to the Power Point) what we are proposing to do and the next steps. <br /> #1 get the sewage out of the basement. There are a number of sewer separation projects that we <br /> need to do in various parts of our community, addressing those 225 homes that we looked at and <br /> surveys in getting that sewage out of their and reducing as such the overall amount of flow that's <br /> going to be going to the system, reducing the overflows to the river and trying to keep as much <br /> of this as we can going to the treatment plant. We know that we are going to have more flow <br /> coming to the treatment plant and our consent decree requires us to change our treatment plant to <br /> meet a peak flow of 100 million gallons a day. Right now we can meet a peak of 77 million <br /> gallons a day and so that is also part of the first phase of projects that we need to do and we are <br /> staring to move forward on and these would be all these project would be ones that we are <br /> looking at doing in this time frame that we are talking about for rates in 2014-2017. So looking <br /> at the, we recently updated our facility plan for the treatment plant and have a plan moving <br /> forward on how do we get to a 100 million gallon per day plant facility. These are the phase I <br /> plans/projects, you see the East Bank, part of that has been done, we still have to do East Bank <br /> Five, Avenue has been done, we've got Oliver Plow, some work to be done there, Kensington <br /> and the sewer separation projects that we talked about as well as Southwood needs to be done as <br /> well sewer separation, and wastewater treatment plant upgrades that I discussed. So next steps <br /> are also at the same time we are moving forward with the Phase I which we talked about getting <br /> the sewage out of the basements and upgrades to the treatment plant we know that we've got <br /> 5 <br />
