Safety analysis of water supply to water treatment plant

Operational reliability of the CWSS is the ability to supply a constant flow of water for various groups of consumers, with a specific quality and specific pressure, according to the users’ requirements in the specific operational conditions, at any time (in which case we use the readiness indicator K) or in the specific time range (then we use reliability function R(t)) (Rak 1993, Rak 2005, Kwietniewski et al. 1993, Tchórzewska-Cieślak & Rak 2010).
