IBM Maximo for Water & Wastewater
Treatment plants, pipe networks in Esri GIS, and SCADA-driven maintenance on IBM Maximo Application Suite, configured for water and wastewater utilities
Overview
ASCE's 2025 Report Card counts about 240,000 water main breaks a year in the U.S., while utilities must also prove compliance under AWIA, the Lead and Copper Rule Improvements, and NPDES permits on a limited capital budget. IBM covers water and wastewater through the Maximo Utilities industry solution, which manages water and wastewater treatment in a single platform and database. Maximo Manage runs plant maintenance, inventory, and calibration. Linear, now included in Manage, models mains and sewers as segments so breaks, inspections, and cleaning are tied to a specific stretch of pipe, and Maximo Spatial shows them on Esri ArcGIS maps. Maximo Monitor and Edge Data Collector bring SCADA and PLC data from pump and lift stations into the maintenance workflow, and Maximo Health scores condition and risk to support capital planning. We configure that stack for your utility and build the models IBM does not ship.
What water & wastewater maintenance leaders are prioritizing
What changed for water utilities in MAS 9
Health & Predict for Utilities was retired at MAS 8.11, and its templates covered electrical assets only, so there is no prebuilt water pipe or pump scoring model. Linear Asset Manager is now Linear, included in Maximo Manage. Maximo Spatial 9.0 deprecated Bing Maps and Google Maps as map providers. Maximo Assist was renamed Maximo Collaborate and is now a Maximo Manage add-on.
The problem
~240,000 water main breaks a year. Estimated U.S. main breaks a year, with roughly $2.6 billion in repair costs
$625B 20-year drinking water need. Of which $420.8 billion is for distribution and transmission pipes
23,000-75,000 sanitary sewer overflows a year. EPA's estimated range of SSOs in the U.S. each year
Mains and sewers are long, buried, and expensive to replace. Without break history, material, and soil data by segment, replacement decisions default to age alone.
Treatment plant staff work in a CMMS while distribution and collection crews work in GIS. Split records make it hard to see total asset risk or cost.
AWIA risk and resilience recertification, the LCRI baseline service line inventory, and NPDES operation and maintenance conditions all depend on accurate asset and maintenance records.
Pump station and lift station telemetry stays in SCADA and historians, so abnormal conditions rarely turn into planned work before a failure.
Attackers have been disrupting internet-exposed PLCs at water systems. Published OT security guidance treats a complete OT asset inventory as the foundation of a response.
Experienced operators and technicians are retiring, taking undocumented knowledge of valves, hydrants, and plant equipment with them.
How we fix it
Linear models mains, force mains, and sewers with reference points, segments, and measures, so work, inspections, and defects attach to the exact stretch of pipe. Maximo Spatial syncs Esri ArcGIS features into asset, location, and service address records and embeds maps in Manage and Maximo Mobile.
AI in practice
Segment attributes such as material, age, diameter, soil corrosivity, and break history can feed Maximo Health risk scores or a custom main-break model built for your network.
Maximo Monitor's Edge Data Collector gathers data from OPC-UA servers, Modbus devices, MQTT brokers, and REST APIs, with store-and-forward through connectivity loss at remote lift stations.
AI in practice
Monitor anomaly detection can flag abnormal pump, blower, and motor behavior, and alerts can be configured to raise work orders in Maximo Manage. Maximo Predict can estimate failure probability once enough history is available to train models.
Maximo Health, a Manage add-on, scores condition, criticality, and risk for pumps, motors, blowers, and mains. Asset Investment Optimization recommends a repair and replace mix under a budget constraint.
AI in practice
The same condition, criticality, and life-cycle cost data answers EPA's asset management core questions and supports GASB 34 modified-approach condition assessments.
Calibration, included in Manage, tracks chlorine, turbidity, and pH analyzers and flow meters. Service line material can be held by service address, with replacement work orders and progress reporting for the LCRI program. Maximo Mobile supports offline pump station rounds, hydrant flushing, and valve exercising.
AI in practice
Maximo stores the evidence regulators ask for, but it does not generate EPA reports such as DMRs out of the box. We configure the queries and reports your permits and programs require.
PLCs, RTUs, HMIs, and cellular modems can be managed as Maximo assets with firmware, network, and location attributes, supporting the automated systems element of an AWIA risk and resilience assessment.
AI in practice
The Maximo Assistant in the MAS AI Service can answer questions such as which assets need attention, drawing on asset and work history.

The platform
Compliance
Risk and Resilience Assessments must cover pipes, treatment, storage, automated systems, and operation and maintenance. Maximo's asset register, criticality, and Health risk scores supply the asset inventory behind the assessment.
Service line material by address, replacement work orders, and a Spatial map of the inventory support the baseline inventory and replacement plan. Litigation is ongoing, so check EPA for the current deadlines.
PM compliance on treatment units, permit-linked job plans, and calibration of discharge monitoring instruments provide evidence for proper operation and maintenance conditions.
Linear sewer segments, cleaning and CCTV schedules, overflow event work orders, and failure codes support CMOM programs required by permits and consent decrees.
Analyzer calibration records, treatment equipment PMs, and sampling station assets support treatment technique and monitoring requirements.
Inventory and condition in Manage and Health, criticality, and investment optimization address EPA's five core asset management questions.
PLC, RTU, HMI, and modem records with firmware and location attributes support the asset inventory and water sector taxonomy the guidance calls for.
There is no OSHA water-specific standard. Confined-space job plans and HSE permits support 29 CFR 1910.146, and PSM (29 CFR 1910.119) applies where chlorine is stored above threshold quantities.
Water is covered by the Maximo Utilities industry solution, which IBM describes as managing water treatment and wastewater treatment in a single platform and database. There is no separate "Maximo for Water" product, so most water-specific capability comes from Manage, Linear, Spatial, and Health.
Maximo Linear models continuous assets such as mains and sewers using reference points, segments, and measures, so work, inspections, and defects can be tied to a specific stretch of pipe. In MAS 9, Linear is included in Manage, and Maximo Spatial shows the segments on Esri maps.
Yes, through the Maximo Spatial add-on. It connects to ArcGIS Enterprise and ArcGIS Online feature services, can sync GIS features into asset, location, and service address records, and embeds maps in Manage and Maximo Mobile. Spatial 9.0 deprecated Bing Maps and Google Maps as providers.
Yes, through Maximo Monitor. The Edge Data Collector gathers data from OPC-UA servers, Modbus TCP/RTU devices, MQTT brokers, and REST APIs and stores and forwards it through connectivity loss. Readings can drive alerts, Health scores, and work orders in Manage.
IBM ships no prebuilt water main model. Main-break risk models typically combine pipe material, age, diameter, soil corrosivity, pressure, and break history, and in Maximo those attributes can live on Linear segments and feed Health risk scores or a custom Predict model.
AWIA Section 2013 requires community water systems serving more than 3,300 people to complete a Risk and Resilience Assessment and an Emergency Response Plan and to review and recertify them every five years. The assessment must cover operation and maintenance and automated systems, which depend on accurate asset records.
Service line material can be recorded per service address or asset, replacement work can be managed as work orders, and Maximo Spatial can map the inventory. EPA's LCRI requirements are subject to ongoing litigation, so confirm current dates with EPA.
CMOM (Capacity, Management, Operation and Maintenance) is EPA's framework for wastewater collection systems to prevent sanitary sewer overflows, often required in NPDES permits and consent decrees. Maximo supports it with preventive cleaning and CCTV inspection schedules on sewer segments, overflow event work orders, and reporting.
Maximo Health scores asset condition, criticality, and risk, and its Asset Investment Optimization recommends a repair and replace mix under a budget. These are the same inputs EPA's asset management framework and GASB 34's modified approach call for.
Cityworks is GIS-centric and popular with municipalities, and Trimble has rebranded it as Trimble Unity Maintain while sunsetting the on-premises version. Maximo is a full EAM covering treatment plant maintenance, inventory, procurement, calibration, linear networks, and GIS through Spatial, and tends to fit larger utilities and those with complex plants.
