Calvin, Giordano & Associates, Inc. (CGA) managed the Town’s Utility Rehabilitation Project from start to finish. The project consisted of investigating the existing potable water, storm sewer and sanitary sewer systems while identifying and performing cost benefit analyses on each required improvement, and construction administration.
The potable water system investigation included fire flow analysis, coupon sampling and as-built review. A new system was designed to increase / maximize available fire flow, and replace deteriorating or known problem areas within the existing system. The project also relocated backyard water meters with front yard services which included AMR (automated microwave readable) water meters resulting in an operating cost savings to the Town. Service sizes were increased to provide for both domestic and landscape water meters thus allowing for a savings to the water charges. The final design included the replacement of over 32,000 LF of water main, 1,587 water services, 1,278 new water meters, and 46 additional fire hydrants.
The sanitary sewer system investigation included video analysis of the existing gravity system, Inflow/Infiltration (I/I) testing, and a review of water consumption vs sewage transmission. Based on the system analysis and facility design life, over 50,000 LF of sanitary sewer main was CIPP lined or replaced. In addition, the Town’s two (2) sewage pump stations were rehabilitated with updated and more efficient pumps including SCADA controls. The force mains from the pump stations to the shared force / transmission main were also replaced. The observed post-construction reduction in I/I has reduced their monthly sewage transfer and disposal costs by over 30%, thus bringing the Town back into compliance with the County issued Consent Decree.
The storm sewer system was upgraded to include three (3) SCADA controlled drainage pump stations, nine (9) shallow injection drainage wells, twenty (20) control structures and the RCP drainage pipe to interconnect the existing gravity drainage system with the newly installed pumped well system. Recent analysis has shown that the utilization of pressure wells has reduced the TMDL discharge into Biscayne Bay by 90%. The reduction in TMDLs was a key requirement in obtaining over $1Million in FDEP grant funding. CGA also administered the installation of over 45,000 LF of curb and gutter replacement as well as 167,000 SY of asphalt roadway resurfacing.
CGA also assisted the Town by obtaining certain funding for this project, which included the Miami Dade Building Better Communities General Obligation Bond, FDEP Grants, Regions Bank publically bid bond issuance, and the FDEP’s State Revolving Loan Program.
