# EQUA AIMMS

> EQUA AI builds EQUA AIMMS, the Autonomous AI Operating System for Critical Infrastructure Maintenance. When critical equipment fails, technicians repair the asset while AIMMS handles all the digital work from fault to fix: bringing evidence together, guiding troubleshooting, tracking safety items, verifying parts and inventory, coordinating suppliers and quotes, routing customer-defined approvals, keeping approved records current, supporting verified closeout, and preserving repair history for the next fault.

Key facts:
- Company: EQUA AI. Product: EQUA AIMMS. Website: https://equa.work
- Primary market: U.S. critical infrastructure. Current focus: municipal wastewater treatment and water resource recovery, extending to power generation and storage, power delivery and grid, and data centers and critical facilities.
- The public fault-to-fix story: FAULT -> UNDERSTAND -> PREPARE -> REPAIR -> RETURN -> LEARN.
- Operational connectivity is read-only (SCADA events, historians, IoT sensor sources). AIMMS does not require control-system writes of any kind and holds no write path to a PLC, DCS or SCADA system: no setpoint, restart, interlock or actuator command, at any permission level.
- Read-only governs what AIMMS may WRITE, not what it may conclude from what it reads. AIMMS connects directly to SCADA, historians and IoT sensors, detects anomalies and deviations in that data, can raise the fault itself and alert the responsible people rather than waiting for an operator to notice an alarm, and surfaces slower drifts as recommended scheduled maintenance. Detection is a read; control is a write; the boundary is on the write. This is not a substitute for a condition monitoring programme: vibration analysis, infrared thermography, oil and wear debris analysis and motor current signature analysis run against ISO 17359 are a separate discipline with their own instrumentation.
- Autonomy is customer-defined: roles, permissions, spend limits, safety policies, and approval gates decide which actions AIMMS may take. Every permitted action produces a time-stamped receipt.
- Existing systems remain in place: CMMS, EAM, ERP, GIS, inventory, procurement, and email. External writeback is configured and validated per customer.
- The four measured metrics, stated exactly: 31.7% lower MTTR (14.2 h to 9.7 h), 80.4% faster quote cycles (4.6 d to 0.9 d), 96% faster quote-to-order (3 d to less than 1 h), and 50% lower measured safety-risk exposure on approval-gated workflows. Measured in one anonymized industrial production deployment. They are not a result in your sector, a forecast, or a universal guarantee. Results vary by workflow, asset mix, data quality, operating environment, and customer controls. MTTR is time to repair, not total downtime, and must not be restated as a downtime reduction.
- The homepage and each sector page open with a pressure chapter: five structural pressures on critical infrastructure maintenance (assets staying in service longer, the people who know them leaving, the repair truth scattered across systems, the right part harder to get right and get fast, less room for downtime), what each does inside one repair, and what AIMMS does about it. Coordination delay is not listed as a sixth pressure because it is what the other five produce when an asset fails. The chapter carries no scope paragraph: it was removed on 17 August 2026 by owner instruction. What bounds the claim is structural instead, and it holds on every page: no EQUA measured metric appears in the chapter, the sector chapters state that published third-party research does not establish AIMMS effectiveness, and the terminal diagram ends on the customer authorizing return rather than on AIMMS producing it.
- Sector pages also publish cited third-party benchmarks (Black & Veatch, AWWA, NERC, Wood Mackenzie, Duke University Nicholas Institute, ASCE, Uptime Institute), each carrying its source and year, and explicitly modelled sector estimates that state their assumptions and assume no AIMMS effect. Neither is an EQUA measurement.

## Resources

Thirty resources, published from May 21, 2026 to September 7, 2026. Two further articles are written but not yet published, and no release date is set for them; they are absent from the site entirely until each is published, and this file is updated with each release. Each answers one operating question or records a company milestone. Third-party statistics carry in-text attribution and a Sources section.

- [The Fault-to-Fix Trace: One Pump Failure, Every Digital Step, Including the Ones That Went Wrong](https://equa.work/resources/fault-to-fix-trace-one-pump-failure): one pre-authored wastewater incident, a mechanical seal leak on a dry-pit non-clog influent pump, traced stage by stage across FAULT, UNDERSTAND, PREPARE, REPAIR, RETURN and LEARN: what was read, what was done, what artifact each step produced, who decided and what was recorded. Includes three points where the first answer was wrong, a superseded part, an inventory record contradicted by the shelf, and an approval gate with no available approver, two of which end in a human decision rather than an automated recovery. The scenario and all durations are authored, not measured, and no EQUA metric appears in it.
- [The Maintenance Benchmark Provenance Ledger: Published, Practitioner Opinion, or Folklore](https://equa.work/resources/maintenance-benchmark-provenance): a figure-by-figure audit of the benchmarks that circulate in maintenance and reliability, including world-class wrench time, 90% PM compliance, the planner-to-technician ratio, the DOE/FEMP predictive-maintenance returns, the Black & Veatch water figures, the Uptime human-error percentages, transformer lead times and the MIT NANDA pilot-failure number. For each: the origin, what was measured, sample and year, and whether it traces to a primary at all. EQUA's own four measured figures are audited in the same table by the same rule, including the business-hours clock behind the 96% figure and the fact that the full measurement method has not been published.
- [A Shift Handover That Carries the Open Fault](https://equa.work/resources/shift-handover-open-fault): US water and wastewater has no published shift-handover standard. UK Health and Safety Executive guidance on effective shift handover is free, government-published and maps onto a plant control room almost unchanged. The translation, plus a one-page handover sheet built so an open fault crosses the shift boundary with its evidence and its reasoning attached, not just its alarm.
- [What "Read-Only" Does and Does Not Buy You: Questions to Put to Any Vendor Reading Plant Data](https://equa.work/resources/read-only-what-it-does-not-buy): a read-only commitment bounds what software may write and answers almost nothing else: not where the component runs, not which zone it sits in, not which side opens the connection, not what happens if the vendor is compromised. Grounded in NIST SP 800-82r3, which is public domain and warns that outbound connections from an OT network carry significant risk. States plainly that a system with no control-system write path can still influence physical work through a wrong recommendation, dispatch, permit status or closeout record. Describes no vendor's deployment, EQUA's included.
- [The After-Hours RFQ Workbook: What to Send at 2 a.m. So the Quote Comes Back Usable](https://equa.work/resources/after-hours-rfq-quote-comparison): two copyable tables. A request-for-quotation content checklist covering the installed configuration rather than the catalogue model, supersession, required-by time, receiving hours, substitution rules and return terms on a wrong part, with one line on what goes wrong when each field is missing. Then a normalisation sheet that makes three quotes with different lead times, freight, warranty and payment terms actually comparable. Carries no EQUA metrics.
- [Grading the Autonomy Claim: The Questions to Ask a Vendor Whose AI Closes Work Orders by Itself](https://equa.work/resources/grading-the-autonomy-claim): a buyer-side interrogation instrument: the question, the evidence a good answer produces, and the red flag a bad answer leaves, across what is autonomous versus drafted, what may be written and to which systems, how autonomy levels are enforced technically, what happens when the system is wrong or an approver is unavailable, and the data and exit questions. EQUA answers its own questionnaire in full, including where the honest answer is that it has not published something.
- [What Your Work Order History Can and Cannot Do](https://equa.work/resources/work-order-history-what-it-can-do): coordinating the next repair and training a model on five years of history are two projects with different data requirements, and vendors routinely conflate them. Ten questions to put to your own CMMS administrator that tell you which one your records can actually support, plus the sequencing argument against cleaning the CMMS first, marked as the publisher's position rather than neutral advice.
- [Mapping the Alarm Tag to the Asset ID: The First Blocker in Every Integration](https://equa.work/resources/alarm-tag-to-asset-id): one pump has a SCADA tag, a maintenance-system asset record, a GIS feature and a spares line, and nothing guarantees they agree. Why the identities diverge, the difference between a tag that identifies a signal and an identifier that identifies an asset, a worked mapping worksheet, and dispositions for the cases that never reconcile: tags mapping to nothing, one tag covering two assets, decommissioned assets still emitting, and spare-part identities that depend on the installed rebuild rather than the nameplate.
- [When EQUA AIMMS Is the Wrong Purchase](https://equa.work/resources/when-aimms-is-the-wrong-purchase): seven situations in which AIMMS is not the right thing to buy, including no read access to operational data, no maintenance system worth writing back to, no defined approval structure, a need that is actually instrumentation coverage or a condition monitoring programme, and a procurement requiring a named reference customer or a published security certification. Also states what EQUA has not published and a buyer is entitled to weigh.
- [What AWWA's 2026 Survey Actually Says About After-Hours Work](https://equa.work/resources/awwa-2026-after-hours-work): AWWA's 2026 State of the Water Industry report added an overtime module. The finding is governance, not hours: 32.7% of the utility respondents to that question report no formal overtime policies or procedures and only 13.0% report comprehensive ones, while investing in technology is named by 7.9% among nine overtime strategies. Reports faithfully that the report's own impact table puts safety incidents as the least affected by overtime, which cuts against the intuitive expectation and against the publisher's commercial interest.
- [The Alarm Is Not the Repair: What Work and Asset Systems Do Next](https://equa.work/resources/what-work-systems-do-after-an-alarm): a neutral buyer guide for water utilities covering Trimble Cityworks, IBM Maximo, Siemens Asset Management Software (Asset Essentials), Cartegraph, CentralSquare Lucity and the broader CMMS field, with current ownership and dates, typical fit, and what each does in the first hour after an alarm. It does not rank them, declares no winner, and states that none of the vendors reviewed it.
- [What EQUA AIMMS Connects To, and What Stays the System of Record](https://equa.work/resources/what-equa-aimms-connects-to): the work and asset management systems (Cityworks, Maximo, Brightly Asset Essentials, Cartegraph, Lucity, Infor EAM, SAP PM, eMaint, Limble, MaintainX, Fiix), historians and control-system event sources read strictly read-only (AVEVA PI, Ignition, Wonderware, Rockwell FactoryTalk, Emerson Ovation, Hach WIMS), geospatial (Esri ArcGIS), finance and procurement (Tyler Munis, Oracle, SAP), and documents (Microsoft 365, SharePoint). States what AIMMS reads, what it writes back only where a customer configures and validates it, and what stays authoritative.
- [AI CMMS, EAM, APM and Predictive Maintenance: What Each Actually Does](https://equa.work/resources/ai-cmms-eam-apm-taxonomy): what each category is for, what it is authoritative over, what question it answers and where it stops, including the three different things vendors currently mean by "AI CMMS", and the EN 61703 decomposition of MTTR into administrative delay, logistic delay, repair time and technical delay.
- [Which Federal Money Can Buy Maintenance Software at a Water Utility](https://equa.work/resources/srf-eligibility-maintenance-software): what EPA's State Revolving Fund guidance says about software eligibility, the asymmetry between the clean water and drinking water funds on asset management systems, the express exclusion of annual support contracts and ongoing software maintenance, and why every path ends at a state determination.
- [How to Measure a Maintenance-AI Pilot](https://equa.work/resources/how-to-measure-a-maintenance-ai-pilot): the clock boundaries, denominators, exclusions and confounders that decide whether a pilot number means anything, plus the conditions attached to EQUA's own four measured figures and a six-item evidence checklist to demand of any vendor.
- [EQUA AI Wins Pitch Pulse 2026 AI & Predictive Systems Session](https://equa.work/resources/equa-ai-wins-pitch-pulse-ai-predictive-systems-2026): EQUA was selected as one of two Session 02 winners after Srikant Naidu presented AIMMS and now advances to the in-person Grand Finale in San Diego.
- [What the 2026 PLC Attacks Mean for Wastewater Operations](https://equa.work/resources/plc-attacks-wastewater-operations): The July 2026 FBI/EPA advisory on internet-facing water-sector PLCs, and what closing that exposure does to maintenance.
