Water & Wastewater

Patrion's field engineering team delivers specialized automation and control services for municipal and industrial water & wastewater facilities, addressing process control, telemetry, instrumentation, and compliance-driven reporting. The group works across treatment plants, lift and booster stations, distribution networks, and wastewater collection systems, deploying and servicing PLC platforms such as Siemens SIMATIC S7 (S7-300/400 to S7-1500 migrations), Rockwell Automation ControlLogix/CompactLogix, and Schneider Modicon series. For SCADA and HMI implementations Patrion integrates AVEVA (Wonderware), Ignition (Inductive Automation), Siemens WinCC, GE/AVEVA iFIX, and Schneider EcoStruxure, plus historians like OSIsoft PI and Wonderware Historian for long-term regulatory recordkeeping and process analytics. Patrion engineers design and commission rugged telemetry architectures using DNP3 (secure and secure DNP3), IEC 60870-5-104 for regional utility interop, Modbus TCP/RTU for field devices, OPC UA for secure data exchange, and HART for instrument-level diagnostics. Remote sites are supported with industry-grade RTUs such as Schneider SCADAPack and ABB RTU500, and communications via licensed radio, private LTE/5G, or cellular with VPN redundancy. Instrumentation partners routinely specified and calibrated include Endress+Hauser, Emerson Rosemount, Siemens SITRANS, and Hach analytical instruments for pH, chlorine, turbidity, dissolved oxygen, and mag-flow metering. Typical projects include PLC/SCADA upgrades, panel fabrication to UL 508A, full FAT/SAT execution, loop checks, instrument calibration traceable to NIST standards, and control narrative and tag database delivery per ISA-95 conventions. Patrion performs PLC code modernization (IEC 61131-3-compliant Structured Text, Ladder, Function Block), alarm rationalization to ISA-18.2 principles, and historian configuration for automated Discharge Monitoring Reports (DMR) and EPA eReporting workflows. Given rising cyber risk and regulatory scrutiny, Patrion embeds cybersecurity controls to IEC 62443 and NIST SP 800-82 guidance: network segmentation using industrial switches (Cisco IE/Ruggedized), firewalls, jump servers, multi-factor authentication, secure OPC UA channels, and IEC 62351 where applicable. The team also delivers predictive maintenance and analytics using vibration sensors, IoT edge gateways, MQTT/AMQP feeds, and condition-based maintenance workflows integrated with CMMS/Maximo. Patrion's field crews execute rapid-response troubleshooting, pump and VFD tuning (ABB ACS880, Siemens SINAMICS, Danfoss VLT), surge/transient mitigation, odor control systems, sludge process optimization, and energy reduction strategies. Deliverables include as-built documentation, instrument datasheets, control narratives, training for operations staff, and lifecycle roadmaps to manage obsolescence and long-term compliance with AWWA, EPA Clean Water Act reporting, and local permit limits.
