Stevens Water Treatment Plant (ONSWTP) currently uses an aging chlorine gas system for disinfection. The facility stores liquefied chlorine gas in 90-ton railcars on-site in an open-air, covered storage area. Due to capacity limitations,redundancy and safety concerns,and potential future regulatory challenges associated with the use of chlorine gas,the City recently decided to replace the existing chlorine gas system with a sodium hypochlorite on-site generation(OSG)system. Implementation of the new OSG system is expected to take 3-5 years. In the meantime, while the new system is being designed and constructed, there are some critical liquid piping improvements necessary to the existing gas chlorine system to ensure safe and reliable operation over the next few years. The pressurized liquid chlorine is piped from the railcar storage area to the gas measurement building where it is first converted to gas at the evaporators, and then metered at the chlorinators prior to injection. A portion of the liquid piping between the railcars and the exterior wall of the gas measurement building was replaced in the past few years and is still in good condition. However,the piping from the exterior of the building to the feed side of the three evaporators was in very poor condition and was in need of replacement. Task authorization No. 26 was previously executed to assist the City in the replacement of the liquid chlorine piping that runs between the outside wall of the gas measurement building and the upstream side of the three evaporators(the portion in poor condition).The task authorization covered the design effort for the piping replacement and provided drawings and specifications for piping, fittings,and appurtenances. The purpose of this task authorization is to continue the work started under task authorization 26. Due to the critical nature of the project, this task authorization will assist the City by providing extensive construction phase support services for the successful replacement of liquid chlorine piping.
