Abstract
Ensuring equipment availability and reliability is critical in utility systems, particularly in water distribution networks. Failures in these systems can have severe consequences, including substantial operational costs and widespread service disruptions affecting large customer populations. Reliability Centred Maintenance (RCM) is a proven and systematic methodology used to determine the requirement and effective maintenance strategy for an asset. Despite the wide implementation of RCM in many industries, RCM implementation in water pump stations (WPSs) is still limited. This is due to several challenges, such as the redundancy nature of WPS’s systems, data accessibility, and difficulty of estimating the benefits of RCM implementation beforehand. The objective of this study is to customise the existing RCM framework for WPS’s and develop a method for estimating the expected cost and benefits of RCM implementation. Water stations can greatly benefit from the implementation of RCM by saving time and money in predicting and mitigating failure risks. The customised approach is demonstrated using a major pumping station located in Dubai. Based on data collected from six failure case studies, changing the maintenance technique to one advocated by customized RCM will reduce cost and improve service availability. Results suggest that benefit to cost ratio gained from maintenance technique change is between 1.15 to 9.06.
