The project consists of furnishing all labor, materials and equipment to perform mechanical integrity testing (MIT) of nine (9) existing injection wells at the Central District Wastewater Treatment Plant (CDWWTP) and one (1) existing injection well at the South Miami Heights Water Treatment Plant (SMHWTP), complying with security restrictions: and all associated and appurtenant items and WORK as specified herein and as required by Miami-Dade Water and Sewer Department (WASD) during the course of the contract. The WORK includes suppressing the artesian flow of the wells with a food grade salt brine, removing the existing well head, scrubbing the 24-inch outside diameter (OD) seamless steel final casing with a steel wire brush, and scrubbing the 25.96-inch and/or 18.18-inch OD Fiberglass Reinforced Plastic (FRP) final casing with a nylon bristle brush (only for the three[3] Industrial Injection Wells [CDIIW-1 and CDIIW-2 at CDWWTP, and SMIIW-1B at SMHTWP]), flushing with potable water, performing a high-resolution video survey log (VSL) of the entire well to be able to see the casing and tubing joints as well as the open hole section, performing a pressure test up to 150 pounds per square inch (psi) on each well final casing, shutting in the well for a twelve (12) hour period, then performing high-resolution temperature (HRT) and conductivity logs, performing the radioactive tracer survey (RTS) using medical grade Iodine 131 (I-131), rebuilding the well head providing new 6-inch 100% gate valves (if necessary), replacing all gaskets, nuts, bolts, and painting all above ground piping. The CONTRACTOR must also meet all the security requirements, which now include having all personnel who will be on-site fingerprinted.
