Chapter 1.0 Summary of Findinqs and Recommendations Water Facilities Work Plan Amendment No. 1 (Amendment 1; to the December 2007 Water Facilities Work Plan (Base Document) was prepared in April 2009 to incorporate additional information and requirements for funding by the Florida Department of Environmental Protection (FDEP) State Revolving Fund (SRF) Program. This Amendment No. 2 to that December 2007 Water Facilities Work Plan was prepared to identify additional projects to remove asbestos cement (AC) pipe from the City of Casselberry water distribution system to reduce water loss resulting from fracturing of the AC pipe because of age and pressure variations. The City of Casselberry has identified several key potable water distribution pipe replacement projects that will improve service and quality to its customers while helping comply with ongoing maximum contaminant limit (MCL) compliance issues associated with EPA's Stage 2 Disinfection Byproduct (DBP) Rule. In addition to helping with MCL compliance via reduced chlorine disinfectant decay coefficients, the proposed pipe replacement projects will conserve a significant amount of water lost to leaks and breaks, reduce operational flushing requirements, increase fire flow capacities and increase cross connection control. The proposed project locations are provided in Appendix A. A number of the proposed projects will result in increased pipe size to a minimum of 6 inches in diameter to enable additional fire hydrants to be added for increased fire protection. The proposed plan is to replace an additional approximately 117,328 total linear feet of water main piping. By pipe diameter, the new pipe is broken down by diameter as: 15,189 linear feet of 12", 6,922 feet of 10", 18,540 feet of 8", 73,527 feet of 6" and 150 feet of 4" asbestos cement water main to reduce pipe fract ares wasting water and manpower.; Including approximately 1,580 feet of 4" water main in order to provide better fire protection. The proposed projects will replace 4,646 feet of 2" polyvinyl chloride (PVC) water main with 6" water main to increase hydraulic efficiency of the system. The total estimated construction cost for the selected alternatives is $8,462,641. It is estimated that it will cost another $169,253 for engineering and $47,104 for administering the projects. A breakdown of these estimated costs is contained in Appendix B.
