The opportunity was taken during upgrade of the Middle Renwick Road, Central Water Treatment Plant and Essons Valley to comprehensively appraise the serviceability of the existing components. All remaining treatment plants are regularly inspected and maintained to a high standard. Progressive upgrades have been undertaken as necessary throughout their life. Distribution and Booster Pum ps - The majority of pumps are monitored through the SCADA telemetry system and critical parameters relayed to operational engineers. Routine maintenance inspections and servicing is undertaken and the pumps are maintained to a high standard. Storage - Asset Condition - There is a considerable range of storage reservoirs throughout the region in terms of material, size, age and condition. Page 55 htgneL sniaM
