The PI System and the Los Angeles Department of Water and Power: A winning combination
- ChallengeAutomate data collection from disparate sources to improve operational oversight and resource monitoring and increase access to critical information
- SolutionsThe PI System becomes the central hub for collecting data sources and enabling data analysis
- BenefitsExpected improvements in safety, resilience, and customer service
A WIN for infrastructure, supply, and safety
LADWP is the largest municipal utility in the nation, serving over 4 million people living within a 500-square-mile service area. A network of over 7,000 miles of pipeline distributes water in the City of Los Angeles from a wide range of sources, including the Los Angeles Aqueducts, the Colorado River, the Sacramento River, local groundwater, and stormwater capture. Recently, the utility launched a project called the Water Information Network (WIN). LADWP Water System plans to use WIN (which relies on the PI System) to help achieve three major goals: improve management of the departments critical infrastructure, diversify its water portfolio, and ensure the continued safety of its drinking water.
Due to infrastructure investments like relining all pipelines, LADWPs distribution network has one of the lowest leakage rates, with water loss of only 5.2%. However, to further reduce water loss, the utility focused on leveraging its existing vast array of flow, pressure, and customer-usage data to gain insights not possible without a time-series database like the PI System.
LADWP also has to deal with the persistent droughts and wildfires that plague California. The utility must closely monitor its water resources to ensure that there is a sufficient supply to serve the community and be prepared for a natural disaster. This means more water needs to be pumped and stored in aquifers for later use. Having real-time sensors of available storage in the aquifers and the amount of extra water in the Los Angeles Aqueduct system helps facilitate operational decisions and keeps Los Angeles ahead of the next crisis.
The PI System enables a data hub
LADWP knows that the key to facing these challenges is to improve the oversight of its operations through automated remote asset monitoring and better data collection.
The utility already has many kinds of data generated by a variety of sources. These include SCADA data, relational data coming from the CMMS system, and customer billing data. In addition, LADWP compiles spatial data from its ArcGIS system and Microsoft file systems, as well as a suite of in-house applications. To integrate these data sources, LADWP decided to use the PI System to create a data hub where information from disparate sources can be brought together and turned into actionable insights.
The point we're trying to drive home here is that we believe that data and data system integration is the key to achieve highly optimized workflow and truly realize a smart utility,” said Nicole Smith, a project manager at LADWP. "We already have a lot of data out there, and we're trying to bring that all into a central location. That's what we're going to use the PI System for."
Another advantage LADWP sees in the PI System is real-time notifications, which can be used to alert users to the condition of various assets. The utility plans to use Notifications to increase situational awareness of its sensitive infrastructure. LADWP also hopes to take advantage of real-time analytics.
“As we combine all that data, new analysis becomes possible through the use of things like AI,” said Vincent Rivera, an engineering associate at LADWP. “That will hopefully lead us to be able to make quick, informed decisions.” In one use case, the utility plans to use AI and analytics to automate treatment, which would make individual water sampling and mitigations a thing of the past. Finally, the department hopes to use PI Vision to create intuitive dashboards that will make it easy for anyone in the company to access critical data.
A notification pipeline
So far, LADWP has launched three pilot projects as part of WIN. In one example, the department is using the PI System to collect data about the groundwater levels in earthen dams. In the past, this data was available only to a couple of people in field offices near the dams. When managers in the home office wanted to know what was happening with the dams, they would have to call and ask the field office to send over Microsoft Excel spreadsheets. PI Vision screens now make data from the reservoir available 24/7 to anyone at LADWP. “The PI System’s built-in automatic notification system is like a second pair of eyes that reassure [us] that the dam is safe” Smith said.
