Lead a 5-person crew maintaining 410 miles of 6–48 in. gravity sewer, 22 lift stations, and 9,800 manholes serving 240,000 residents. Reduced SSOs from 27 to 10 per year by building a risk-ranked cleaning schedule in Cityworks that targets grease and root hot spots on 30-, 90-, and 180-day cycles. Run a combination jet-vac truck program that cleans 1.3 million linear feet of main a year, 18% above the department target. Plan and supervise CCTV inspection of 85 miles of pipe annually; code defects to NASSCO PACP standards and feed rehab priorities to engineering, shaping a $4.2M CIPP lining program. Supervise permit-required confined-space entries (300+ per year) with zero lost-time injuries over 4 years; wrote the crew's updated entry and rescue checklist. Set up emergency bypass pumping for 6 main breaks and 2 force-main failures, restoring service within an average of 5.5 hours. Train new operators on jetter safety, traffic control (MUTCD), and lift-station rounds; 4 crew members have since earned Class II licenses.

Performed hydro-jetting, root cutting, and vacuum cleaning on 160 miles of sanitary sewer; consistently top producer in feet cleaned per shift. Completed weekly checks on 11 lift stations: pump amperage, wet-well levels, floats, and SCADA alarms; replaced impellers, check valves, and level transducers. Logged and closed 1,400+ work orders in Cityworks and helped migrate 12 years of paper maintenance records. Responded to after-hours customer backups and SSO events, completing state-required overflow reports to Idaho DEQ within 24 hours.

Installed and repaired storm drain inlets, catch basins, and culverts; operated a backhoe, mini-excavator, and 10-yard dump truck. Set up work-zone traffic control for crews on arterial roads with daily volumes above 30,000 vehicles.
