10 <br /> 1 Slide #12 <br /> Why Use Advanced Pre-Treatment? <br /> Overcome a Limiting Site Condition <br /> or <br /> Increase System Capacity <br /> 2 <br /> 3 Chair Bedford asked if OWASA's sewer treatment plant is like a massive package <br /> 4 treatment system with the addition of chlorination treatment. <br /> 5 Tony Whitaker said municipal systems like OWASA, use other processes to simulate the <br /> 6 biological activity, like activated sludge. He emphasized that these processes are still about <br /> 7 using natural biological processes to affect biochemical changes. <br /> 8 Chair Bedford asked if OWASA also discharges wastewater into the stream once <br /> 9 treated. <br /> 10 Tony Whitaker said yes. <br /> 11 Commissioner Carter asked what the difference was between monitoring in a system <br /> 12 like OWASA's vs. a package treatment system. <br /> 13 Tony Whitaker said OWASA is required to report to the state and are highly regulated in <br /> 14 terms of the quality of discharge. He said they also likely do test every day for some particles. <br /> 15 He explained why someone would use advanced pretreatment despite the expense. He said <br /> 16 advanced pretreatment is a way to overcome limiting site or soil conditions and increase system <br /> 17 capacity. He explained that given the same amount of soil and the same type of soil, it's <br /> 18 possible to have a bigger system with advanced pretreatment, which means more homes on the <br /> 19 same soil for a developer. <br /> 20 <br /> 21 <br />
