佛罗里达州奥兰治县水务局启动了预测性维护计划，而不是预防性维护计划。工作人员使用流量和压力指示的泵性能来启动维护。为了促进该计划，该县正在用机械密封更换所有填料和填料函，包括对立式涡轮泵进行特殊改造，以接受密封函。该县还将所有轴承更换为密封轴承。对于大型控制阀，限位开关已更换为接近开关，以防止O形圈磨损。现在，余氯检测器被指定为膜式，使用盐水来消除耗时的化学或气体供给系统。对于县级建筑，规定使用聚氨酯或丙烯酸涂料，以最大限度地减少高温潮湿环境中的降解。

The Orange County, Florida Water Department has initiated a predictive maintenance as opposed to preventive maintenance program. The staff uses pump performance as indicated by flow and pressure to initiate maintenance. To facilitate this program the County is replacing all packing and stuffing boxes with mechanical seals, including special modifications to vertical turbine pumps to accept the seal boxes. The County is also replacing all bearings with sealed bearings. For large control valves the limit switches have been replaced with proximity switches to prevent O-ring wear. Chlorine residual detectors are now specified to be membrane type using saltwater to eliminate time-consuming chemical or gas feed systems. For County structures, polyurethane or acrylic paints are specified to minimize degradation in the hot, moist environment.
