(i) All hose bibs shall be provided with caps and shall be kept capped except when in use.
(f) All bulk tank openings and valves shall be kept closed and completely sealed at all times to prevent contamination from entering the tank.
(g) A manhole shall be provided for routine maintenance, cleaning and sanitizing.
(i) The manhole shall be large enough to enter for inspection.
(h) A drain at the lowest point in the tank shall be provided to allow for complete drainage.
(i) All reducers, adapters, pipe fittings and any other water-handling equipment carried on board must be stored protected in dust-proof containers.
(j) All tank valves and other openings shall be kept closed, latched, and sealed when not in use.
(a) When using an overhead standpipe filling source, the filler hose shall terminate at least two hose diameters above the overflow of the tank and must be supported by a device which will provide for overhead protection of the fill hole.
(i) Threaded or clamped caps must be attached to the discharge and entry points of the standpipe and shall be used to protect the standpipe when it is not in use for filling.
(b) When filling through a direct connection:
(i) A vacuum breaker or other suitable means to prevent backflow from the bulk tank into the water system is required at the filling source; and
(ii) Filler hoses remaining attached to a hydrant shall be:
(A) Tightly capped; and
(B) Stored off the ground; or
(C) Flushed; and
(D) The connecting end sprayed with a sanitizing solution prior to connecting to the bulk tank.
(a) When water is discharged from the bulk tank, the manhole and all other openings to the air must remain closed and be properly vented and screened to prevent the entrance of contaminants.
(b) The fill hose opening of the receiving tank must be protected from contamination during the filling procedure.
(c) During discharge, backflow of water from the receiving tank to the discharge (bulk) tank shall be prevented by one of the following methods:
(i) Maintaining an air gap between the discharge hose and the receiving tank;

(ii) Filling the tank with a diluted (50 ppm) chlorine sanitizing solution and allowing it to sit in the tank for 24 hours. Approximately one gallon of bleach containing 5.25% sodium hypochlorite will make 1,000 gallons of a sanitizing solution with a concentration of 50 ppm. A chemical test kit must be used for verifying the concentration of sanitizers; or
