One system for your plant — headworks to
final effluent report.
ComplyFlo replaces paper logbooks, spreadsheets, and disconnected apps with one secure platform built for how wastewater plants actually operate — from daily parameter logging and process control to monthly DMR packages and TCEQ compliance tracking.
We reduce human error in data organization and formatting. Operators retain full responsibility for data accuracy and final DMR submission to TCEQ.

The problem today
Paper logbooks. Disconnected spreadsheets.
A month-end DMR scramble.
Most wastewater plants today track daily readings in paper logbooks, calculate process parameters manually, manage SSO events on whiteboards, and compile monthly DMRs from spreadsheets that no single person fully controls. ComplyFlo replaces that entire system.
- Operators log DO, pH, TSS, MLSS by hand in a paper logbook — re-entered into a spreadsheet for reporting
- Process calculations (SVI, F/M, SRT) done by hand or in isolated spreadsheets — formula errors go undetected
- Monthly DMR compiled from multiple spreadsheets under deadline — one tab wrong, one submission wrong
- SSO events logged on notepads — the 24-hour TCEQ verbal notice tracked manually, 5-day written report drafted from scratch
- Permit milestones tracked in a calendar or not tracked at all — renewals missed, CEUs lapsed
- Microbiology results recorded on paper — no link to SVI or DO trends that explain what's happening
- Maintenance tracked in emails and sticky notes — no record of what was done or when
- No single view of plant health — operators check multiple systems or nothing at all
- Single-tap parameter entry from the plant floor — DO, pH, ammonia, chlorine, TSS, MLSS, and custom parameters all in one place
- SVI, F/M, SRT, HRT, RAS rate, and more calculated automatically from live readings — no manual math
- Monthly DMR package generated from the data you've been entering all month — one-click export
- SSO events logged with automatic TCEQ countdown — 24-hour verbal notice timer, 5-day report pre-filled and printable
- Permit milestones tracked with lead-time alerts — DMR due dates, TPDES renewals, operator CEUs, sampling schedules
- Microbiology log overlaid on SVI, DO, and MLSS trends — bulking risk, toxicity events, and nitrification stress flagged automatically
- Equipment registry with PM schedules, work orders, and chemical inventory — maintenance tracked the same place everything else lives
- Live plant dashboard with per-train tiles — one screen shows the whole plant
"ComplyFlo found a formula error in a consultant's manual SVI/BOD calculation that was about to go into a TCEQ submission."
Process calculations done by hand or in spreadsheets carry formula drift risk — one incorrect cell, copied across months, produces wrong DMR values before anyone notices. ComplyFlo computes every formula from your live readings automatically, using the correct formula every time.
Plant Dashboard
One screen. Your whole plant.
The ComplyFlo dashboard gives operators, lab techs, and plant managers a live snapshot of plant health — not a summary built hours after the fact.
Flow, DO, pH, MLSS, SVI, F/M ratio, and chlorine residual shown as live cards — each with its latest reading, trend direction, and permit limit status. Out-of-range readings flag in red immediately.
Permit limit alerts in real timeFor parallel treatment plants, each train gets its own F/M and MLSS tile. Compare train performance side by side — see where a process issue is isolated before it becomes a compliance issue.
Multi-train POTW supportCorrelate wet-weather events with process upsets directly on the dashboard. When flow spikes after a rain event, you can see exactly what happened to your parameters at the same time.
Wet-weather event context"Days since last SSO" displayed at the top of the dashboard. Open events surface with overdue-report alerts. One click to the full SSO event record.
TCEQ notice countdowns visibleNext DMR due date, TPDES renewal window, upcoming sampling events, and operator CEU deadlines — all visible on the dashboard with lead-time alerts so nothing sneaks up on you.
No missed deadlinesFor plants with anaerobic digesters, the VFA/Alkalinity ratio tile shows stable / warning / souring status automatically. Volatile solids reduction and gas production tracked alongside.
Anaerobic digester supportParameters & Readings
Single-tap entry. From anywhere in the plant.
Operators log readings from a phone or tablet — no paper logbook, no re-entry later. Every reading is timestamped, attributed to the operator who entered it, and tied to the physical asset it came from.
Aeration basin DO with permit limit alert and trend. Low DO surfaces immediately on the dashboard.
Influent and effluent pH tracked with permit min/max range. Out-of-permit readings flagged in red.
Water and ambient temperature. Impacts nitrification kinetics — overlaid on F/M and SRT trends.
Influent and effluent ammonia for nitrification tracking. Permit exceedance alerts built in.
Effluent nitrate for nutrient compliance. Tracked alongside ammonia for full nitrogen picture.
Total residual chlorine (TRC) for disinfection compliance. Dashboard tile shows live status vs. permit limit.
Effluent turbidity for filtration compliance. Trending view shows filter performance over time.
Effluent TSS and mixed liquor suspended solids. MLSS feeds SVI and F/M calculations automatically.
MLSS, TSS, and VSS testing has a dedicated lab worksheet — enter your raw measurements, ComplyFlo calculates the results automatically. No spreadsheet, no formula to remember. Results feed directly into SVI and F/M calculations.
Plants with existing SCADA or PLC systems can stream readings directly into ComplyFlo via a secure token-based API — no manual entry required for instrumented parameters. Per-train and per-digester tagging so data lines up with the physical asset it came from.
Process Calculators
The math your operators do every day — done automatically.
Every calculator pulls from your live parameter readings — no re-keying, no spreadsheet, no formula drift. Results update the moment a new reading is entered.
Target 80–150 mL/g. Above 150 suggests bulking. Above 250 is severe. 30-day trend shown automatically.
Food-to-microorganism ratio for process control. Target 0.2–0.5 lb BOD/lb MLVSS·day for conventional AS.
Solids retention time — critical for nitrification (needs 8+ days at 20°C). Tracks WAS flow, effluent TSS, and total volume.
Calculates the daily WAS volume needed to hit a target SRT. Takes the guesswork out of wasting decisions.
Return activated sludge flow rate for maintaining target MLSS. Updates when MLSS or influent flow changes.
Aeration basin HRT — target 4–8 hours for conventional AS. Flags when flow pushes HRT below safe range.
Secondary treatment standard ≥85%. 30-day trend chart shows if removal is drifting before it becomes a permit issue.
Disinfection dose calculation with target CT value. Helps operators dial in chlorine without over-dosing.
Microbiology
Know what's living in your aeration basin — before it causes a problem.
Activated sludge microscopy is one of the most useful diagnostic tools available to a plant operator — and one of the least documented. ComplyFlo gives it a proper digital home.
Log activated-sludge microscopy results on a 0–6 abundance scale for filaments, protozoa, and indicator organisms. Attach microscope photos directly to the record. Custom organism catalog per plant.
ComplyFlo's advisor interprets your microbiology scores against your current SVI, DO, and F/M values and flags risk conditions in green / yellow / red — bulking risk, young sludge, toxicity events, and nitrification stress.
The microscopy timeline overlays biology scores directly on SVI, DO, pH, and MLSS trend lines. See exactly which organism abundance change preceded the last SVI spike — and use it to catch the next one earlier.
Compliance & Regulatory Tools
Every TCEQ deadline tracked. Every report pre-built.
ComplyFlo models the compliance obligations that wastewater plants actually live with — not a generic checklist, but TCEQ-specific event types, countdowns, and report formats built into the platform.
Log sanitary sewer overflows with location, cause, volume, receiving water, containment, and cleanup actions. Automatic countdown for TCEQ's 24-hour verbal notice and 5-day written report. One-click 5-day report pre-filled from the event record.
24-hr & 5-day TCEQ deadlines auto-trackedRecurring deadline tracking for TPDES renewal, monthly DMR, PPR, CMOM, BAR, permit sampling schedules, and operator license renewals — with lead-time alerts so nothing catches you by surprise.
Alerts fire before the deadline, not afterLightweight registry for significant industrial users (SIUs), categorical and non-categorical dischargers, and hauled-waste accounts. Sample results auto-flagged for exceedances. Inspection records and NOVs stored and searchable.
Pretreatment program supportTCEQ Class A/B/C/D/OIT license tracking with expiration alerts. Live CEU progress bar per operator so administrators can see at a glance who's on track and who needs hours before their renewal window.
CEU progress bar per operatorYour monthly Discharge Monitoring Report generated from the parameter readings you've been entering all month. NetDMR-ready format, fiscal year Sep 1–Aug 31, one-click export. The data is already there — the report just builds itself.
One-click export — data already enteredWhen your plant ships biosolids or sludge to a compost or disposal facility, ComplyFlo digitizes the outgoing manifest — transporter, disposal site, TCEQ numbers, cubic yards, receiver signatures — stored and searchable forever.
Outgoing loads to compost / disposal sitesPlant Operations & Maintenance
Equipment, maintenance, and chemical inventory — in the same system as everything else.
Most plants track maintenance separately from process data — a whiteboard here, an email chain there. ComplyFlo puts equipment history, PM schedules, and chemical inventory in the same platform your operators already use every day.
Asset registry for every piece of process equipment. Manufacturer, install date, service intervals, maintenance history, and current status — searchable and tied to the process trains they support.
Configure maintenance intervals per asset. ComplyFlo generates work orders automatically when a PM is due — parts needed, estimated labor hours, and assigned technician. No one has to remember to schedule it.
Log chemical usage per dosing event. Track on-hand inventory, order history, and consumption trends. Know when you're running low before the weekend shift finds out the hard way.
Pretreatment Surcharge Billing
Turn hidden costs into recovered revenue.
Most wastewater plants lose thousands of dollars a month to high-strength waste they treat but never bill for. Our Surcharges module automates the entire surcharge program — from lab result to invoice line item — so every pound of BOD, TSS, FOG, and ammonia gets captured, calculated, and collected.
Why plants need this
Hauled-in and industrial waste hits your headworks at 10x–100x the strength of domestic sewage. Without a surcharge program, your residential ratepayers are subsidizing industrial dischargers. Surcharges shift that cost back where it belongs.
Every calculation is tied to a specific lab sample, manifest, and ordinance rate — with a full audit trail. When a hauler or industrial customer disputes a charge, you have the math, the chain of custody, and the signed manifest in three clicks.
Key benefits
Gallons × concentration × 8.34 happens automatically the moment a lab result is entered. No spreadsheets, no transcription errors.
Set your own $/lb for BOD, COD, TSS, FOG, ammonia, pH penalties, and any custom parameter your ordinance covers. Update rates annually without touching historical invoices.
Only charge for strength above domestic baseline (e.g. BOD over 250 mg/L). Thresholds are configurable per customer or per waste stream.
Industrial permittees, septage haulers, FOG haulers, and grease trap pumpers can each have their own rate schedule and exemptions.
Surcharge line items flow straight into the customer's monthly bill alongside disposal fees. One invoice, one payment, one QuickBooks/SnapTax sync.
Pull results directly from your LIMS or enter manually. Either way, the sample is locked to the manifest and the customer.
See surcharge revenue by parameter, by customer, and by month. Identify your top-loading dischargers at a glance.
Export the reports your council, EPA region, or state primacy agency expects — pretreatment program summaries, SIU loading reports, and annual surcharge revenue totals.
The bottom line: Plants using our Surcharges module typically recover 15–40% more revenue from high-strength waste in the first year — money that was already being treated but never billed. The module pays for itself in the first month and funds the capital improvements your headworks actually needs.
SCADA & Data Integration
Works with whatever data path your plant can provide — today.
Not every plant will approve a direct SCADA connection on day one. ComplyFlo doesn't require it. We accept whatever your plant can reliably deliver — from manual uploads to historian extracts to live OPC UA feeds — and move you up the automation curve at your own pace.
Immediate reduction in transcription errors. Operators upload whatever they have — ComplyFlo maps, calculates, and validates.
Daily automated data capture for compliance reporting from historian or reporting tools — without requiring direct SCADA API access.
Near-real-time compliance monitoring, automatic daily rollups, and exception alerts from live plant tags. Coming Phase 3.
CSV/XLSX uploads, manual mapping, daily validation, month-end review package.
Automated daily pulls from plant historian and reporting databases.
Near-real-time tag reads via lightweight site gateway. No inbound firewall holes.
Ignition and VTScada templates. MQTT broker ingestion for plants already publishing OT data outward.
Facility templates for common permit types, audit-ready evidence packs, and guided NetDMR preparation.
Security model
Read-only. Outbound-only. Your SCADA stays in your hands.
Water and wastewater cybersecurity guidance is clear: cloud-connected OT data requires segmentation, least privilege, and defense in depth. ComplyFlo's integration architecture is designed around these principles from the ground up. We are a compliance data layer — not a SCADA system, and never a SCADA control path.
Security by design
We read your data. We never write to your systems.
Every integration ComplyFlo supports is read-only. We cannot write to PLCs, historians, or SCADA systems. Our local connector uses outbound-only connections — your plant never opens an inbound firewall hole to the cloud.
No write capability to SCADA, PLCs, or historians. Ever. Read-only enforced at the connector level.
The site connector makes outbound connections only. No inbound firewall rules required. Your OT network stays segmented.
Only pre-approved DMR-relevant tags are ever read. No browse-all access. Your plant defines exactly what ComplyFlo can see.
Every imported, adjusted, reviewed, and approved value is logged with timestamp and user identity. Immutable and exportable.
The integration layer is architecturally separated from ComplyFlo's SaaS tenant environment and from plant business IT networks.
Multi-factor authentication required for all users. Role-based access controls limit what each user can view, edit, review, or approve.
Who ComplyFlo is built for
Purpose-built for every type of wastewater facility.
Whether you run a small package plant or a multi-train POTW, ComplyFlo scales to fit — the same platform, configured for your permit parameters, your trains, and your regulatory requirements.
Multi-train activated sludge plants, water reclamation facilities, and utility districts (MUDs, WCIDs) that need to modernize paper logbooks and prove TCEQ compliance.
Small plants with lean staffing that need one system — not five — to log readings, track compliance, and generate monthly DMRs without a dedicated compliance manager.
Plants with industrial user programs that need to track SIU permits, log sample results against limits, manage inspections, and store NOVs in one searchable system.
Contract operators managing multiple plants who need consistent data entry, centralized compliance tracking, and exportable reports without building custom systems for each client.
Advanced treatment plants with nutrient limits, reuse permit requirements, and more complex monitoring schedules that benefit from ComplyFlo's flexible parameter and milestone tracking.
The built-in process calculators make ComplyFlo a useful tool for operator exam prep and on-the-job training — real plant data, real formulas, real-time results.
