The lagoon is thirty minutes out of town and the reading you need was taken four minutes ago. It is on the phone in your pocket, next to the band it is supposed to be inside.
LagoonGuardYour basin, on your phone, every fifteen minutes of the year.
The service is a sonde in the water. The product is what shows up on your phone
Six signals. Every fifteen minutes. On a screen you already carry.
CI LagoonGuard puts a solar-powered sonde in the basin and a live picture of that basin in an app. Dissolved oxygen, pH, level, temperature, turbidity and conductivity report every fifteen minutes to a phone, a tablet, and a browser. Readings arrive with the band they should be inside. Alerts arrive with what to do next. The record writes itself.
An operator on two site visits a week observes the basin for roughly two hours out of 168. The other 166 are inferred. Almost every expensive lagoon event — overflow, permit excursion, odour complaint, winter collapse, surprise dredging — happens inside that gap and is found afterwards. What follows is the same week, with and without the app.

- Show live dissolved oxygen, pH, level, temperature, turbidity and conductivity on phone and browser.
- Learn each basin’s own daily and seasonal rhythm, then alert on departure from that rhythm.
- Send an alert that states the reading, the consequence, and the first three moves.
- Generate the operating record and the reporting exports that support WSA and WSER submissions.
- Connect a measured condition to the CI360 Municipal Wastewater chemistry that answers it.
- Control equipment. Nothing in the app starts an aerator, opens a valve, or doses a tank.
- Replace laboratory analysis. Permit parameters still require sampling and accredited lab results.
- Replace the operator. It shortens the time between a change and a decision.
- Require a control building, hardwired power, or a SCADA project to be useful.
- Report a number without context. A reading with no threshold behind it is not a service.
The field unit is deployed on an isolated monitoring path. Sensors read the lagoon; they cannot operate it. There is no button in the app that changes how the facility runs. Physical operation, permit decisions, and emergency response remain with the certified operator and the owner.
Three mornings at the same lagoon, as they arrive on the phone
Pick a morning. The screen and the operator’s next move both change.
This is the working surface. Not a chart library and not a SCADA screen shrunk to fit — a single scrollable list of what the basin is doing right now, ordered so the thing that needs a decision is at the top. Most days it says nothing needs you. That is the point of it.
Screens and values shown are representative of a facultative Prairie lagoon. Actual bands, sensor set and alert routing are set per basin at commissioning against that basin’s own baseline.
The basin is named the way the operator names it, with a live indicator and the age of the last reading. If the link drops, the header says so rather than showing a stale number as if it were current.
Every signal shows the value and the band it is in. 4.2 mg/L means nothing on its own to a relief operator at 03:00. 4.2 mg/L · Good is a decision.
An open condition appears directly beneath the reading that caused it, in the colour of its severity, with the sentence an operator needs. Everything else on the screen stays quiet. There is no wall of red icons to learn to ignore.
Status is carried by a labelled pill and a border, not by colour alone — readable in a truck at noon, and readable by an operator with colour vision deficiency.
Any signal opens to its own 24-hour, 30-day and season traces. The overnight minimum, the diurnal swing, and last year’s same week are already calculated.
Acknowledging an alert writes a name and a timestamp. That line is what answers the question a year later about who knew what, and when.
- Live values with their band, one screen, no configuration.
- Push alerts with the response steps inside the notification.
- Acknowledge with one tap; the log records who and when.
- Switch basins from a list when the site has more than one.
- Works on the cellular signal you already get at the site gate.
- All basins side by side with status at a glance.
- Overlaid traces, derived metrics, and season-over-season comparison.
- Alert history with acknowledgement and resolution against every entry.
- Report generation and export in regulator-ready formats.
- Role-based access for operator, administrator, viewer and inspector.
The browser view is where the week gets explained and the report gets made
Same data, more room. Built for the desk, the trend, and the submission.
The phone answers what is happening now. The dashboard answers what has been happening, and what do I file. Multi-basin sites get a rail with a status colour against every lagoon, so the first thing an operator sees on Monday is which basin has moved and which have not.
| What the console is showing | Why it belongs · operator note | |
|---|---|---|
| 1 | Every basin on one screen | Status colour on each lagoon in the rail, so a nine-basin utility sees the whole system before it sees any single number. The one that needs attention is the one that is not green. |
| 2 | Cards carry the verdict, not just the value | Each signal shows its reading, its unit, and its state. A warning card changes its border and its label; it does not rely on the operator remembering that 82% is close to the line. |
| 3 | One banner for the open condition | The same rule as the phone. The condition that needs a decision sits above the charts with the number and the rate of change in the sentence. |
| 4 | Trends read together, not one at a time | Dissolved oxygen and pH on one 24-hour frame, because the shape of the pair is the diagnosis. A flat pH under a falling DO in summer is a biology problem, not an instrument problem. |
| 5 | Everything on the screen exports | The same view becomes a CSV, a PDF, or a formatted compliance report. Nothing is retyped into a spreadsheet to become a submission. |
DO saturation against temperature, diurnal swing, pH stability index, level change rate, treatment efficiency trend and season-over-season comparison are calculated from the six sensors. Raw values ask the operator to do the correlation by hand, from memory. Derived metrics do it in advance.
Administrator, operator, viewer and inspector roles, with multi-factor authentication. An inspector can be given a read-only account against a defined period instead of being sent a folder of screenshots.
An alert that does not say what to do is a louder version of the problem
Reading, consequence, first moves, expected recovery. Four parts, every time, in that order.
Most monitoring products fail here. They push a number and a red icon to somebody who is driving, and the operator learns to dismiss them. LagoonGuard notifications are written to be acted on by a competent operator who is not a water chemist and who may be looking at a lock screen in a truck.
Warning · Cell 1 · Dissolved oxygen 1.8 mg/L. Below 2.0 for three readings. Odour risk begins here. Tap for response steps.
Weekly summary ready · Fort Qu’Appelle Lagoon.
Lite delivers by email. Pro adds SMS and app push. Enterprise adds a phone call on an unacknowledged critical. Whichever channels a site carries, the four-part wording is identical, so an operator reads the same thing on a lock screen, in an inbox, and in the console.
A critical level alert is an operational emergency, not a data point. It is delivered on every channel the tier supports and it stays open until a person acknowledges it. Freeboard is the only signal on this service where the correct response to uncertainty is to drive out.
Dissolved oxygen has dropped to 1.8 mg/L and has been below 2.0 mg/L for three consecutive readings.
Below 2.0 mg/L the aerobic bacteria are oxygen-stressed. Sustained, this produces incomplete treatment and hydrogen sulphide — the rotten-egg odour that generates complaints.
- Check whether the aerators are running, if the basin is equipped.
- If there are no aerators, reduce organic loading where that is possible.
- Watch the trend. If DO falls below 1.0 mg/L, contact Chem International technical support.
With aeration restored, DO should recover within four to six hours. If the basin is unaerated, this may be a normal pre-dawn low — check the trend before acting.
“Expected resolution” is what separates a useful alert from an anxious one. It tells the operator whether this is an emergency, a watch item, or a normal feature of the basin they have not seen written down before. It is also what stops the 04:00 call that did not need to happen.
| SignalSensor and code | WarningWatch and diagnose | CriticalAct now | First moveBefore reaching for a product | Escalate only if… |
|---|---|---|---|---|
| S1Dissolved oxygen | < 2.0 mg/L sustained | < 1.0 mg/L | Confirm aerator status. Check load and temperature before dosing anything. | The overnight minimum keeps falling across three consecutive nights. |
| S2pH | < 6.5 or > 8.5 | < 6.0 or > 9.0 | Check for an upstream discharge. Confirm against the permit range before reporting. | The daily rhythm disappears entirely, or the stability index climbs week over week. |
| S3Level / freeboard | 75% of capacity | 90% of capacity | Establish the rate of rise, then find the source: rain, thaw, pump, or collection system. | Rate of rise increases while the cause remains unidentified. This one escalates on the clock. |
| S4Temperature | Ice cover detected | Abnormal stratification | Declare the seasonal state and move the biological programme to the correct thermal lane. | Ammonia or BOD results diverge from what the temperature band would predict. |
| S5Turbidity | > 25 NTU | > 50 NTU | Read the shape. Ramp points inside the basin; step points upstream. | Clarity does not recover after the bloom window closes. |
| S5Conductivity | ± 20% from baseline | Sustained step change | Log the timestamp and correlate with known discharges. The time of day is usually the answer. | The shift persists past one operating week, or the baseline itself is climbing year over year. |
| Rule of thumb | Thresholds are commissioned per basin against its own baseline, then written down and left alone. A threshold that gets adjusted every time it fires is not a threshold; it is a preference. | |||
If a threshold fires every night, it is wrong. Commissioning includes a seven-day supervised period specifically to tune bands against how this basin actually behaves. An operator who ignores alerts has been trained to by the system that sent them.
Every alert, acknowledgement and resolution is retained. When an odour complaint or a permit question arrives months later, the answer is a timestamped trace rather than a recollection. That record is frequently worth more to the municipality than the alert that created it.
Five signals decide whether a lagoon is treating — and nobody is standing there when they move
Five signals. Six sensors. One sonde.
The screens above are only as good as what is behind them. Six sensors on one sonde carry five signals: oxygen, chemistry, capacity, season and load. Each is banded against this basin’s own baseline, not a textbook. Tap a band on the section drawing to see what it covers.
The basin stores rather than treats. Protect what biology remains and hold the record for spring. Product intervention rarely earns its place here.
Cold-adapted support is the correct lane. CI ColdZone BioLift holds activity through the range where ordinary biology stalls.
Standard operating range. Watch ammonia against DO and load rather than changing the biological programme.
CI HotZone BioLift is formulated for lagoons at 25.5°C and above, where metabolic demand and low oxygen arrive together.
Cold-water and warm-water biological products are not stronger and weaker versions of each other. They are different organisms selected for different thermal ranges. Running the warm-season product through a cold basin is not conservative — it is the wrong lane. The temperature sensor is what makes that a measured decision instead of a calendar one.
Odour counteractant suppresses the malodour. It does nothing about the oxygen deficit, the sludge burden, or the upstream load that produced it. Use it to hold the community relationship while the measured cause is corrected — and record both, so the next complaint season starts from evidence.
The reporting period ends and the report is already written
The second product is the file, and it is the one that is worth the most a year later.
Every reading, alert, acknowledgement and resolution is retained for the term of the tier. The report is generated from that record rather than assembled by hand from a clipboard, a spreadsheet and a memory of what the week was like. What used to be an afternoon is a download.
What the record has to survive is a question asked a year later.
Saskatchewan Water Security Agency permits require lagoon operators to monitor and report effluent quality — typically BOD, TSS, pH, chlorine residual where disinfection is used, and fecal coliform — at an inspection frequency set by system classification. Federal Wastewater Systems Effluent Regulations apply to systems collecting more than 2,500 m³ per year or serving more than 10,000 people, with regular effluent monitoring reported to Environment Canada.
LagoonGuard is supplementary to both. It does not certify effluent quality and it does not replace accredited laboratory analysis. What it does is supply the continuous operating record behind the samples: what the basin was doing between submissions, when conditions changed, what the alert was, who acknowledged it, and what was done. That is the part of a file that is normally missing.
Continuous sensor data supports permit reporting. It does not replace effluent sampling or laboratory analysis for compliance. Confirm reporting obligations with your regulator and permit conditions.
What a compliance report contains.
Facility name, permit number, reporting period, and the certification statement naming the LagoonGuard system serial and the operating client.
Days in compliance, alerts triggered, actions taken, and daily minimum, maximum and average for every monitored parameter.
Thirty-day, ninety-day and annual charts, plus every threshold breach with its timestamp and its resolution.
Calibration records and the maintenance log — the evidence that the data behind the report was trustworthy.
Hosted in Canadian cloud regions, with handling aligned to Canadian privacy legislation.
TLS 1.3 in transit, AES-256 at rest, certificate-based device authentication.
Administrator, operator, viewer and inspector roles, with multi-factor authentication.
Raw data held one to five years; aggregated trends retained substantially longer for season-over-season comparison.
The field unit has no control authority over lagoon equipment. It reads and reports.
Enterprise sites can pull data into existing SCADA, CMMS or reporting systems through a secure API.
LagoonGuard is a CI SupportLab service, and it is designed to sit alongside the CI360™ Municipal Wastewater programme rather than replace anybody’s judgement about it. The measured condition selects the lane: oxygen demand points to oxygen release and sludge reduction, temperature selects the biological support product, and a conductivity step points upstream to the collection system. Sites running both get a chemical review cadence driven by data instead of by the calendar.
One pole, one sonde, under two hours — and it has to survive a Prairie winter
The part of the service that is not on a screen.
The hardware constraint that matters on the Prairies is not accuracy. It is surviving −40°C, running on solar through a short December day, and holding a cellular link from a basin outside a town of 700. The field unit is a pole-mounted enclosure with a solar panel and a battery large enough to carry several days without sun, connected to a weighted sonde suspended at roughly half a metre. No control building, no trenching, no hardwired power.
| Component | Specification | Why it is specified that way |
|---|---|---|
| 1 | EnclosureIP67-rated polycarbonate or aluminium, NEMA 4X | Roughly 30 × 25 × 15 cm.Small enough to mount on an existing fence post or pump-house wall without a structural conversation. |
| 2 | Operating range−40°C to +60°C | Rated for Prairie winter and Prairie summer.The failure mode that matters is a unit that stops reporting in February, which is precisely when the site is hardest to reach. |
| 3 | Power20 W solar panel and 40 Ah lithium battery | Three to five days of autonomy without sun.Sized for short winter days and overcast weeks, not for average annual irradiance. |
| 4 | Communication4G LTE primary, satellite fallback | Transmission every 15 minutes, configurable; burst transmission on an alarm event.Satellite is the answer for genuinely remote basins where a cellular link cannot be relied on. |
| 5 | SecurityVPN tunnel, AES-256 encryption, certificate-based authentication | Encrypted in transit (TLS 1.3) and at rest.The monitoring path is isolated by design: the unit reads the lagoon and cannot operate it. |
| 6 | Sonde deploymentWeighted PVC or stainless sonde on a dock, pump house, or floating buoy | Intake at approximately 0.5 m, adjustable to the basin design.Placed away from inlet and outlet turbulence so the reading represents the cell rather than the pipe. Auto-cleaning is available for high-solids basins. |

Non-invasive current clamp on the aerator feed. Turns “check whether the aerators are running” into a fact instead of a drive.
Ultrasonic sludge blanket measurement. Makes dredging a planned capital item rather than a discovered one.
Air temperature, wind, precipitation. Correlates rainfall with level change. This is what makes thaw and storm overflow predictable.
Ion-selective electrode. Advanced nutrient monitoring where the permit or the loading justifies the added cost and calibration burden.

Client tasks
Trained during onboarding
Wipe biofilm and solids from the sonde. This single task prevents most false trends.
Clean the solar panel. Dust and snow cover are the usual causes of a power alarm.
CI field technician
Scheduled service visits
pH electrode calibration monthly; turbidity cleaning and calibration every three months.
DO sensor cap inspection and replacement; DO and conductivity calibration.
Annual
CI technical team
Battery health check, full system audit, firmware update, and a threshold review against the year of data.
Season-over-season comparison — the report that tells the owner whether the basin is holding or degrading.
Water quality sensors in a lagoon foul. Optical caps age, pH electrodes drift, and biofilm forms on everything left in the water. A monitoring service that does not name a cleaning and calibration schedule is a monitoring service that will quietly stop being accurate in its second year.
Three levels — what changes is coverage and cadence, not whether the service works
Every tier includes installation, onboarding, cellular data, app access, and CI technical support.
A hamlet with one basin and a good operator does not need what a regional utility with nine lagoons and an API requirement needs. The sensor platform and the app are the same in all three tiers; what moves is how many parameters are read, how often they report, how long the record is kept, and how much of the compliance paperwork is generated for you.

How much of your lagoon are you actually watching?
Enter your real visit schedule. The readout is arithmetic, not a sales estimate.
The number that decides whether this service is worth anything to a facility is not a price. It is the proportion of the year the basin is observed, and the hours currently spent driving to observe it. Put your own schedule in and the tool returns the coverage arithmetic, the tier that matches the site, the sensor array that goes with it, and the CI360 chemistry lanes worth pre-staging for the conditions you selected.
Set the four numbers on the left, tick whatever is true about the site, and the readout will show how much of the year the basin is currently observed against what continuous monitoring would produce.
This is a screening calculator, not a quotation or a design. Sensor selection, thresholds, mounting and service scope are confirmed against the actual basin during site assessment. Nothing here changes permit obligations.
Two to three weeks of unfiltered data before any threshold is finalised. Every band in the app is set against the lagoon’s own behaviour.
Warning and critical for each signal, agreed with the operator and recorded. A threshold nobody agreed to is a threshold nobody will act on.
First contact, second contact, channel, and what happens when a critical alert goes unacknowledged. Decided before the first one fires.
A supervised go-live week to remove the alerts that fire on normal basin behaviour. This is where alert fatigue is prevented.
Monthly cleaning, calibration intervals, and the annual audit booked into the work-order system rather than remembered.
Thresholds, contacts, sensor placement and design freeboard recorded where the next operator will find them.
Hours per week with no data. This is the number the service exists to move, and it should approach zero.
Alert issued to alert acknowledged. A rising figure usually means the thresholds need tuning, not that the operator needs reminding.
Alerts that turned out to be normal basin behaviour. Should fall sharply after the go-live week and stay low.
Percentage of expected transmissions received. Drops here are power, link, or fouling, and each has a different fix.
Routine monitoring trips replaced by remote data. Track it honestly; emergency trips do not count.
Hours per reporting period. This is the benefit that finance understands without having to be taught lagoon chemistry.
CI SupportLab™ LagoonGuard is a monitoring service guide, not a substitute for site-specific engineering, permit conditions, or operator judgement. Application screens shown are illustrative representations of the operator interface; layout, values and alert wording are configured per site. Sensor accuracy, thresholds, transmission intervals and service scope are confirmed per site during assessment and commissioning. Continuous sensor data supports regulatory reporting; it does not replace effluent sampling or accredited laboratory analysis. Confirm all product dilution, dosage and handling against current labels and SDS before use.
