3. Lift Station Pump Performance <br />Results of the 41ift station pump performance tests will be presented in a <br />separate letter report. <br />C. Conclusions <br />The following are the conclusions reached by ADS based on all collected data and <br />available information: <br />• Parts of the system are in an advanced state of disrepair, with numerous <br />deteriorated manholes and lines, as well as structural failures. <br />• Numerous tees and end-of-line segments in the collection system make <br />proper system maintenance difficult. <br />• Continuation of the current preventative maintenance program will alleviate <br />sewer backups in areas were they occur. <br />D. Recommendations <br />The following activities should be undertaken as part of an overall plan to <br />improve the city of Paris' wastewater collection and transmission system and <br />reduce wet weather overflows: <br />Complete rehabilitation of all defects in the five highest rated basins (PR13, <br />PR30, PR29, PR06, and PR07) at a cost of approximately $880,000. <br />Conduct post-rehabilitation flow monitoring in these five basins to determine <br />the effectiveness of the rehabilitation program. <br />Update the hydraulic model using the data collected from the post- <br />rehabilitation flow monitoring and permanent flow monitors. Results from <br />the updated hydraulic model will be used to validate current assumptions and <br />reconfirm the recommendations for rehabilitation and capacity improvements <br />ADS Environmental Services, Inc. <br />I-2 <br />
