Lawson Maximo Interface Benefits
• Inventory Link to Maximo– Assist planner in locating parts in warehouse for
corrective maintenance– Spare parts can be added to preventive maintenance work
orders– Kitting of parts can be completed electronically
• Equipment Cost Information– Material costs are captured on each work order and used
to quantify cost for snow events or emergencies– Material costs are captured for each equipment item and
used for repair verses replacements

Process Control & Project Support
• Comprised of 9 staff with a wide array of background,education and expertise including:
1 - Instrumentation specialist1 - Sr. Field Inspector3 – Engineers2 - Project Managers2 - Program Managers.
• Staff were previously spread throughout FODproviding a variety of operational and technicalproject support functions.
• Group has been in place for approximately 8-months.
![Page 14: Field Operations Department Wastewater Operations ... · • 284 miles of water distribution piping • 11 pump stations • 11 storage facilities • 4700 valves Transport System](https://reader035.vdocuments.net/reader035/viewer/2022081411/60b0c54a51d277762d0696f8/html5/thumbnails/14.jpg)
Future Program Objectives
• Increase use of available tools to support daily work activities (GISapplications, GPS systems, hydraulic modeling, Process Book, SCADAdata, Historical Operation data, etc).
• Work to further optimize CSO operations, chemical treatment (residualanalyzers), energy consumption, headwork choking, etc.
• Improve use of SCADA systems and adjust operational setpointsthrough facility audits and coordination with operations staff.
• Evaluate facilities during peak operations to help determine whatimprovements are required to enhance performance and ease ofoperation.
• Refine maintenance service contracts to ensure critical maintenanceneeds are met and work is preformed cost effectively and efficiently.
• Work towards streamlining and electronically documenting permittingprocess and reviews.

Siphon Program Goals and Methodology
1. Sonar inspect each siphon once every three years.2. Maintain each siphon once every four years.3. Siphons that have been identified to be historical
maintenance problems, maintain once every quarter.
Yearly Target Numbers1. Inspect 20 siphons (48 individual barrels) each year.2. Maintain 15 (38 individual barrels) siphons each year.
