Customers will receive at least a month's notice of the changeover. Back to top Fire Protection Even with the new zones, water pressure will not be any lower than the current pressure in the central part of Cary. Town officials have been planning the Western and Southern pressure zones since 1992 and have tried to keep people building in those areas informed. A sprinkler system that was designed to handle the reduced pressure probably will not require any adjustment. A qualified engineer will need to check the sprinkler system to determine whether adjustments are necessary.
Water pressure is only one of several criteria that fire insurance rating services use.
The change in system pressure should not affect homeowners' fire insurance premiums. Even with the new, lower pressures in the western and southern zones, the Town's distribution system will equal or exceed National Fire Protection standards. The pressure change could affect commercial customers with calculated sprinkler systems. Individual engineering evaluations will be necessary for those sprinkler systems to determine whether equipment such as a booster pump is needed. The Cary Fire Department will work with these customers.
