Assessing Risk for Operations Reliability and Asset Protection at Six MWRDGC Pumping Stations

Risk reduction is a common strategy for municipalities managing infrastructure in order to protect both public health and existing assets. The Metropolitan Water Reclamation District of Greater Chicago (District) is evaluating and addressing risks resulting from the loss of key components to improve the operations reliability and asset protection for the following six critical pumping stations:

1) Racine Avenue Pumping Station (3,910 mgd Station, Originally Constructed in 1938)

2) North Branch Pumping Station (1,115 mgd Station, Originally Constructed in 1927)

3) Walters Road Pumping Station (9.2 mgd Station, Originally Constructed in 1962)

4) 95th Street Pumping Station (553 mgd Station, Originally Constructed in 1924)

5) 122nd Street Pumping Station (253 mgd Station, Originally Constructed in 1963)

6) 125th Street Pumping Station (737 mgd Station, Originally Constructed in 1918)

The size and complexity of these pumping stations required a multi-disciplinary team of engineers and operators to evaluate the systems and propose modifications that could reduce the overall risk of critical vulnerabilities. A condition assessment was performed at each pumping station to identify the current status of the civil, process-mechanical, structural, building mechanical, electrical, instrumentation, controls, maintenance, and operations systems. This information was compiled and used as the basis for the Risk Assessment Study Sessions. During the study sessions, the risk level associated with the components in each station was ranked using the consequence and likelihood of failure. The final ranking list provided a basis for the District staff to select high priority/impact vulnerabilities. These vulnerabilities were then evaluated to determine the level of modifications required to reduce the risk level. Some specific examples of the risk reduction evaluations will be presented.
