The design of the tank will utilize the pumps to fill the tank as needed but then once the storm event has subsided and flows are down to means that the sewer and plant can accept them, we will then drain the tank by gravity back into the sewer system. The system is completely enclosed and it will have a dome on top of the tank to prevent odors. There are vents associated with the tank and when the tank is filling the air will need to be displaced or when the tank is draining air would need to be brought into the tank to prevent the tank from pressurizing, or pulling a vacuum. These vents are tied to a dual carbon filter system to mitigate odors since the location of the tank is adjacent to a residential area. Also the tank will not have wastewater in it at all times since this will only be utilized during storm events. The building is approximately 125 foot in diameter and it can store about 1.5 million gallons at peak capacity and by using the hydraulic model with the pumps we are able to fill the tank at a rate of 10 million gallons a day in order to alleviate the flooding, and the hydraulic concerns that are historic for this area. Mr. Olivos asked how the facility be will be enclosed? He stated that he sees an eight -foot chain link fence however does not see a gate on the plan. Mr. Fallon answered the entire perimeter of the site will have an eight -foot chain link fence and there is a dual swing gate for vehicles to enter onto the main drive. There will be a stone path that leads to the manhole structure that will also have an individual swing gate for staff to enter the structure for maintenance and cleaning on the interceptor. Mr. Olivos asked if the facility will be mostly automated. Mr. Fallon answered yes. It will be tied into the plant to the SCADA communication system so it can be observed and monitored from the waste water treatment plant. Mr. Fallon also noted that there will be a generator that will be used for backup since the need for the tank is during storm events. Mr. Matthews commented on the choice of using Owens Corning Brownwood roofing materials and asked about the choice. Mr. Fallon answered that they were a few factors in choosing the roof material. First, since the current site is an undeveloped wooded area the thought of going with shingled hip roof versus a flat roof was to be cognizant of the residential areas surrounding the undeveloped areas to the site. Second, they wanted to match the appearance of the other sanitary lift stations located throughout the city. Third they wanted to be cognizant of the Army Corps and the wooded area and have the roof look natural and be non obtrusive. Mr. Matthews noted that he understood the choice and reasons to make the building unremarkable. Director Upton commented that in the preliminary discussions regarding flat roof cmu brick versus what is presented on the plans is to maintain the same rooftop profile as the surrounding neighborhood so it looks and blends in. Mr. Olivos observed that the tank will be underground however from the plans there are not any notes on the material of tank. Mr. Fallon answered that the majority of the tank will be below grade and the top four feet of the tank will stick out above grade which will be poured concrete. On top of the poured concrete there will be a flat aluminum geodesic dome. 2
