Mechanical Integrity Test of Deep Injection Wells IW-1, IW-2, IW-3, and IW-4 at the South Regional Wastewater Treatment Plant

Work under this Contract consists of the Mechanical Integrity Testing for Deep Injection Wells No. 1, No. 2, No.3, and No. 4 at the South Regional Wastewater Treatment Plant.

The City of Hollywood (City) owns and operates the Southern Regional Wastewater Treatment Plant (SRWWTP). The SRWWTP is permitted to treat an average annual daily flow of 55.5 million gallons per day (mgd). The SRWWTP has four (4) deep injection wells (IW-1, IW-2, IW-3, and IW-4). As specified in Rule 62-528, Florida Administrative Code (FAC), deep injection wells must demonstrate both internal and external mechanical integrity every 5 years. Mechanical integrity testing (MIT) for all the deep injection wells at the SRWWTP and net MITS are shown in the table below:

MIT of each injection well will consist of performance of a video survey, pressure testing, temperature logging, and performance of a radioactive tracer survey (RTS). The Florida Department of Environmental Protection (FDEP) requires that a MIT Plan providing testing procedures be submitted to, and approved by, the Underground Injection Control (UIC) program of the FDEP. Additionally, it will be necessary for the City to hire a well testing Contractor to perform the actual MIT of the wells. A set of Technical Specifications detailing the testing procedures is required for the City to solicit competitive bids from potential testing Contractors.

Brown and Caldwell, along with its subconsultant, McNabb-Miller Hydrogeologic Consulting, Inc. (MMHC), has completed the MIT Plan and technical specifications. The same team will perform the professional services associated with the MIT testing.
