Assessing and maintaining Fire Hydrants is fundamental in Distribution System Management in order to protect the public welfare, improve a utility’s ISO rating and can aid in maintaining water quality when incorporated into an organized flushing program.
A number of conditions can affect a hydrant’s performance including Water System improvements, changes affecting zone valve settings, usage changes, damage from accidents or vandalism, wear and tear, deterioration, mechanical malfunction and work performed on water lines without hydrant isolation valves being reopened. Uncovering any of these problems and correcting them prior to the hydrant being needed is imperative to determine fire hydrant capabilities in the event of an emergency.
In addition to determining fire flows, testing can uncover mechanical problems from valves that don’t operate properly, to leaks and even pump damaging debris flowing from hydrants. Flow test data also provides essential field information to aid water service planners and the Fire Prevention Bureau to accurately estimate water main capabilities. Water main and hydrant flow capabilities influence decisions about required fire protection and fire resistance features for new developments; where priorities should be placed; and Water System upgrades of older, smaller water mains.
R&M’s Fire Hydrant Maintenance and Assessment program is designed to comply with AWWA Waterworks Distribution Standards (M17) and meet the requirements of environmental oversight agencies.
