DRY FIRE HYDRANT OPERATION AND MAINTENANCE System must be checked and pump tested upon completion to verify system capacity and condition. Perform regular pump test and back flushing on at least an annual basis or as per NFPA recommendations. Records and schedules should be coordinated with local fire department training and testing needs. Maintain access to dry hydrant free of debris and woody vegetation. Keep the all-weather road clear of snow and debris and in good repair. Maintain area in pond around intake strainer free from floating debris and all pond vegetation that could become lodged in the strainer during pumping. Water weeds must not be allowed to plug the inlet of the pipe.
