Are the treatment vessels protected? (i .e. fenced from vandals , irrigation water is not <br /> sprinkling over the equipment, birds/vermin are not nesting overhead/near by)? YIN <br /> Note configuration of each vessel, is it the lead , lag, first, middle or last in the series? Is vessel contaminating those located <br /> down stream <br /> PRESSURE TANKS Tank ID: Tank ID Tank ID COMMENTS <br /> Is a pressure tank positive for Bacteria? YIN . If N , go to next. section. <br /> What is the MPN concentration of bacteria from the effluent of each tank? <br /> Has any work been done on a tank? If Y, note date. YIN <br /> Is each tank protected to prevent unauthorized access? YIN <br /> Note if the tank is a bladder (B) or hydronuematic (H) tank. <br /> Is tank or piping/valves/man-way/sight tubefinternal bladder at a tank leaking? YIN <br /> Did the system lose pressure below 5 psi (Le lose electrical power; break a water line; <br /> lose a pump; run out of water). Is pressure holding at the tank? YIN <br /> Are there any connections to irrigation , fire, industrial piping that could be cross - <br /> connections? (backflow devices removed, need repair, need to be installed) YIN <br /> Is pump cycling on and off, is pressure tank holding pressures, is tank <br /> waterlogged (lacks air space in the top 1 /3-1 /2 of the H tank) or has a hole in the <br /> bladder of a B tank? YIN <br /> Has any work been done on the system? (repair water line, install/replace/repair a component; use of <br /> a pressure washer; serve water for an event that used more water then normal) YIN <br /> Is tank protected with a backflow prevention device? If Y, what type YIN <br /> Has the tank been cleaned of sediment? If Y, note date YIN <br /> Was tank water logged with chlorinated water after the last TCR MCL? YIN <br /> If Y, note date <br /> STORAGE TANK USED TO STORE SYSTEM WATER? If N, then go to next Tank ID: Tank ID : Tank ID COMMENTS <br /> section . <br /> Is a storage tank positive for Bacteria? YIN . If N, then go to next section. <br /> What is the MPN concentration of bacteria in effluent of each tank? <br /> Is each tank protected to prevent unauthorized access? YIN <br /> Is the tank properly vented with a down turned and screened "J" vent? YIN Birds vermin and debris can enter <br /> into the tank w/o vent screens <br /> Has the tank been clean of sediments and disinfected to overflow levels after the last TCR Bacteria can reside rsediments and <br /> MCL? YIN not be eliminated duri ng disinfection <br /> process. <br /> What is chlorine residual (total/free) of the water exiting the storage tank today? <br /> Are there any unsealed openings in the tank such as access doors, vents or joints? YIN <br /> How often is the water in the storage tank changed ? Water that resides too long may grow <br /> bacteria <br /> Is the storage tank leaking at seams, bottom , connections, valves , hatches? YIN <br /> Has any work been done on the system? (repair water line, install/replace/repair a <br /> component; use of a pressure washer; serve water for an event that used more water <br /> then normal , did tank run out of water) YIN <br /> Page 4 of 6 <br />
