The current upgrades to the Main WWTP and MOLS required the MOLS to be bypassed using the 30"force main to allow the 36"line to be removed from service during upgrades. The 30" line failed when the bypass pumps were energized and upon inspection was found to have deteriorated beyond use. The failure of the 30" line leaves the MOLS dependent upon the single 36" force main which does not have enough capacity to handle the permitted peak flow of the Main WWTP and the line is 50 years old and beyond its expected useful life. If the 36" line were to fail the full flow of sewage to the Main WWTP would have to be discharged into the DD7 canal to prevent overflows throughout the City especially in the area around Duff Drive between Lakeside Drive and Lewis Drive. This situation would continue until a replacement line could be procured and installed which could take 4 to 6 months. Due to the health and safety risk associated with a failure of the main in addition to potential fines, we request approval to issue a change order to ALLCO, LLC under the Main WWTP Improvements contract for the engineering and construction of a 42" parallel force main with associated connections. The expenditure for the engineering and pipe replacement is expected to be approximately $5,650,000.00. I Ronald Burton,hereby approve the emergency change order to ALLCO, LLC.
