Chlorination facilities for disinfection, when required, shall be located in a separate room adjoining the pump operating room.

For in-line booster stations, the chlorination shall be automatic; and for booster stations with pumped storage, a manual system is considered adequate. However, the need for chlorination facilities and mode of operation shall be checked with WSSC, before start of design.

For layout of the chlorination facility, mode of operation, controls, major components, heating and ventilation, safety requirements, etc., refer to the Mechanical and Electrical Design Guidelines for Chlorination Facilities (under preparation at this time). (28-ME-DG-02 § 11)
