The software will help the city assess the condition and performance of its sanitary sewer system to identify and solve problems

Innovyze announced that the city of Oakland, Calif., has chosen Innovyze InfoMaster software to help optimize its sanitary sewer infiltration and inflow (I/I) reduction program.

Oakland is the third largest city in the San Francisco Bay Area, the eighth largest in California, and the 45th largest in the U.S. with a population of 413,775. Its underground contains more than 930 miles of sanitary sewer pipes, the approximate distance from its city hall to Denver. The sanitary sewer system includes 31,000 structures and seven pump/lift stations. The city is responsible for the public sanitary sewer main pipes that carry waste to the treatment plant, while the East Bay Municipal Utility District is responsible for sanitary sewer treatment and disposal.

“InfoMaster gives us the critical powers of risk-based asset integrity and mathematical modeling while fully leveraging our existing geospatial asset management solutions and hydraulics and CCTV data,” said Jimmy Mach, P.E., supervising civil engineer for Oakland. “These powerful capabilities will enable us to accurately assess the condition and performance of our sanitary sewer system, effectively solve our I/I problems, prioritize and optimize our capital planning expenditures based on rigorous analytics, and meet regulatory requirements.”

Certified by NASSCO PACP, MACP and LACP V6.0, InfoMaster can accurately estimate both the likelihood and consequence of failure for each individual sewer main in the network, as well as the amount and time of occurrence of future failures. This information facilitates a proactive approach to identifying and managing these high-risk assets to help preserve structural integrity and keep the network operating into the future. It also eliminates reactive maintenance: waiting for pipe failures to occur before repairing.

InfoMaster comprehensive risk-based asset integrity modeling techniques provide reliable pipe failure predictions, even for limited failure records and application to different pipe materials. These techniques can be effectively used to evaluate a variety of pipe characteristics related to failure, and can consider all pipes in the network, not just those with breaks or other failures. Armed with these models, utilities can accurately assess the aging processes of their network pipes and estimate their lifetimes and structural/functional failure potential and distribution over time. Such capabilities can greatly assist utilities in assessing their pipes’ propensity to fail, identifying critical ones (more prone to failure), prioritizing their inspection and determining rehabilitation requirements.

The product suite automatically imports InfoSWMM hydraulic network models and gives utilities insight into all enterprise assets, their conditions, aging and work processes. It also features direct integration with Cityworks, Cartegraph, infraMAP and Lucity, and can interface with other maintenance management software. It enables utilities to use information and analytics in new ways to drive higher productivity and quality while managing costs and increasing operational flexibility.
