The water travels from the clearwell to the high service pump chamber where it <br />is pumped into the distribution system. Fluoride, chlorine, and phosphate will be added to the <br />finished water. <br />Main Level <br />Chemical Rooms <br />Chemical rooms are clustered on the east side of the building with exterior doors to allow easy <br />access for chemical deliveries. It is expected that chemical rooms will be required for chlorine <br />gas, sodium permanganate, fluoride, phosphate, and possibly polymer to aid in backwash <br />settling. <br />High Service Pump Room <br />The high service pump room contains the pumps that pump treated water from the clearwell into <br />the distribution system. Because most of the electrical load is located in the high service pump <br />room, it is in close proximity to the electrical room and generator room. <br />Electrical Room <br />The electrical room contains the motor control equipment and electrical panels. The location of <br />this room in close proximity to the high service pump room, mechanical room, and generator <br />room provide for short conduit and wire runs. <br />Mechanical Room <br />This room contains the make-up air, dehumidification, and HVAC equipment. The location of this <br />room on an outside wall provides space for air louvers. <br />Blower Room <br />The blower room contains the filter backwash blower. The backwash blower provides air which is <br />used to help clean the filter media during a backwash. <br />Office/Control Room/Lab <br />An office/control room/lab is provided for operators to have a SCADA computer to monitor and <br />control the water system. A lab sink and desktop analyzer will be provided to allow operators to <br />monitor water quality. The office is located in the front of the building next to the entrance, and <br />has lots of windows for natural light. <br />Generator Room <br />A standby generator will be located in the generator room. The generator is capable of running <br />the water treatment plant in the event of a power outage or possibly for peak shaving (peak <br />shaving requires additional emissions compliance). The service entrance and automatic transfer <br />switch are located in this room. Two exterior walls are provided for intake and exhaust louvers. <br />Upper Level <br />The upper level is depicted on the Upper Level Floor Plan in Appendix F. The upper level <br />consists of filters and walkways. Windows will be provided in the filter room to allow for natural <br />lighting. Walkways will be provided around the filters to allow the plant operator to inspect the <br />FEASIBILITY STUDY -DRAFT RAMSY 154354 <br />Page 29 <br />
