Document Description
Note: Revised Replace the existing gaseous chlorine and anhydrous ammonia storage and feed systems with a liquid sodium hypochlorite and aqua ammonia storage and feed systems. The objectives of the project include; 1) mitigate the risks to community, operating staff and environment associated with accidental spills or leaks of gaseous chlorine and ammonia during the transportation and application of these chemicals in the drinking water treatment process; 2) Improve the reliability of the disinfection systems; and 3) Reduce the costs to permit and maintain the chlorine gas and anhydrous ammonia systems. The Project work activities would occur within the Antioch WTP site with the majority of facilities located within existing buildings and existing outdoor chemical containment structures. The anticipated duration of construction is 13 to 15 months.
