The methodology presented for pumping stations is based upon three models: a supply model, a demand model, and a margin model. The supply model considers so-called states of a system which define the operational condition of each pump. The demand model also uses the concept of states which refer to different water demand levels. The demand model is used to determine the availability, frequency of demand states, and transition rates of the states. The margin model computes the difference between supply and demand provided that the required head is satisfied. The frequency and duration (F&D) analysis then uses the three models above to compute failure probability, failure frequency, and cycle time of failures for the pumping station. F&D analysis also provides information for computing other reliability parameters.
