6. Discharge from the softening units to the sanitary sewer cannot be measured. This means that <br />operation of the process cannot be monitored and no accountability for the amount of water <br />discharged exists. To remedy this problem, discharge flow meters on each softening unit will <br />be installed. <br />M <br />7. The electrical system consists of nearly all original equipment. The original motor starters and <br />incandescent lighting systems will be replaced for enhanced reliability. <br />8. The existing automatic control valves on the softening units arc original equipment and no longer <br />function reliably. These valves will be replaced. <br />9. The interior ferrous metals in the water plant building show signs of corrosion due to <br />condensation. Increases in the amount of ventilation and dehumidification inside the facility to <br />control the problems ass^iated with condensation will be made. <br />10. The plant’s control systems are at the end of their useful life. This equipment will be replaced <br />with a new supervisory control and data acquisition (SCADA) system. <br />11. The piping within the water treatment plant is all original. As renovations take place, all related <br />piping will be inspected and replaced as necessary. <br />The improvement! <\uilined above will extend the usefu? ’ of the water treatment plant an <br />additional 20 t - 25 years. Iron and manganese levels in u.c acated water will be below the <br />Secondary Standards of the Safe Drinking Water Act. <br />Because of the proposed changes in the operation of the softening units, a more uniform, more stable <br />treated water will be produced. This, in turn, will help to alleviate problems with high copper and <br />lead levels in the distribution system. <br />Navarre WTP Rehabilitation <br />»»
